In 2015, a Pakistani court in the case of Leghari v. Federation of Pakistan made history by accepting arguments that governmental failures to address climate change adequately violated petitioners’ rights. This case forms part of an emerging body of pending or decided climate change-related lawsuits that incorporate rights-based arguments in several countries, including the Netherlands, the Philippines, Austria, South Africa, and the United States (US). These decisions align with efforts to recognize the human rights dimensions of climate change, which received important endorsement in the Paris Agreement. The decisions also represent a significant milestone in climate change litigation. Although there have been hundreds of climate-based cases around the world over the past two decades – especially in the US – past and much of the ongoing litigation focuses primarily on statutory interpretation avenues. Previous efforts to bring human rights cases have also failed to achieve formal success. The new cases demonstrate an increasing trend for petitioners to employ rights claims in climate change lawsuits, as well as a growing receptivity of courts to this framing. This ‘rights turn’ could serve as a model or inspiration for rights-based litigation in other jurisdictions, especially those with similarly structured law and court access.

The sooner that they realize that global warming is much more than the plight of polar bears and other animals or just some abstract warming of the planet or ocean acidification; the sooner that they come to Jesus and realize that the people are being harmed right now and will be increasingly harmed; that’s a much better way to advocate for climate change policy than arguing for protections for the polar bear. So if Leonardo Dicaprio wanted to be a bigger player on global warming he should step up and advocate for people instead of polar bears.Footnote 1

In September 2015, Judge Syed Mansoor Ali Shah of the Lahore High Court in Pakistan made history with his finding that the national government’s delay in implementing the country’s climate policy framework violated citizens’ fundamental rights.Footnote 2 A few months earlier, the Hague District Court in the Netherlands had handed down its decision in Urgenda v. The State of the Netherlands to considerably more media fanfare.Footnote 3 The Hague District Court ordered the Dutch government to adopt more stringent greenhouse gas (GHG) emissions reduction measures in line with international scientific recommendations.Footnote 4 In the academic and media commentary that followed the Urgenda decision, much was made of the case being the first to use a tortious cause of action to hold a government to account for its inadequate climate change mitigation efforts.Footnote 5 Far less remarked upon were the rights-based arguments put by the Dutch non-governmental organization (NGO), Urgenda, in support of its contention that the Dutch government was not doing enough to protect its citizens from climate change harm. Unlike the Lahore High Court in Leghari, which based its decision on the breach of rights obligations, the Hague District Court did not find a violation of the petitioners’ human rights in Urgenda. Nonetheless, it gave serious consideration to the arguments based on human rights, and used rights as an interpretative tool in analyzing the question of whether the Dutch government had breached its duty of care towards Urgenda and the Dutch people.Footnote 6

While cases that urge courts to address climate change on human rights grounds are not an entirely new phenomenon,Footnote 7 success in rights-based climate change claims has been more elusive. However, the result in the Leghari case, coupled with other recent pending and decided cases that raise rights arguments, suggests that this situation may be changing.Footnote 8 In addition to the Urgenda case, petitioners have raised rights claims in recent climate change litigation in the Philippines,Footnote 9 the United States (US),Footnote 10 Austria,Footnote 11 and South Africa.Footnote 12

Up to this point, the vast majority of lawsuits in countries with the most extensive climate change litigation, such as the US and Australia, have involved statutory law causes of action alleging that governments failed to take climate change considerations adequately into account in their decision-making processes.Footnote 13 The most high-profile US climate change case to date, Massachusetts v. Environmental Protection Agency,Footnote 14 focused on statutory interpretation: whether the US Environmental Protection Agency (EPA) had abused its discretion through the manner in which it refused to regulate GHG emissions under the Clean Air Act.Footnote 15 However, climate change lawsuits based on claims of rights violations represent a turn away from these more conventional modes of litigation.Footnote 16 They coincide with the increasing prominence internationally of human rights–climate change linkages, including the endorsement of this linkage in the Preamble to the Paris Climate Agreement concluded in December 2015.Footnote 17 In parallel with these policy and legal developments at the international level, rights claims in climate change litigation seek to direct public and political attention to the detrimental human consequences of climate change, arguments that ultimately may be more persuasive in motivating action to address the problem.Footnote 18

This article contends that emerging case law, such as the Leghari and Urgenda decisions, illustrates a trend towards petitioners increasingly employing rights claims in climate change lawsuits, and a growing receptivity of courts to this framing. As early cases demonstrate the potential of rights-based claims in a climate change context, they are likely to encourage similar cases in other jurisdictions. This could facilitate a greater ‘turn’ towards rights in climate change litigation around the world. Indeed, human rights suits are particularly apposite as the basis for the development of a transnational climate change jurisprudence given the widespread adoption, and similarities in formulations, of rights across diverse legal instruments, including human rights treaties, domestic statutory or constitutional bills of rights, and national and subnational constitutional rights provisions.Footnote 19 Moreover, with worsening impacts from climate change which affect human communities more directly and substantially,Footnote 20 linkages between climate change and rights protection are likely to become ever more salient, attracting further litigation on this basis. While it is important not to overstate the extent of this ‘turn’ – and many jurisdictions may continue to be largely resistant to such framingFootnote 21 – this emerging jurisprudence represents an important step forward for rights arguments in the climate change context.

To ground the analysis of this case law in this article, Section 2 provides an overview of the likely human rights impacts from climate change, which have become an increasing focus of human rights bodies and the international climate change regime over the past decade. It also briefly surveys the principal previous attempt at rights-based climate change litigation – a 2005 petition by the Inuit peoples to the Inter-American Commission on Human Rights – to identify the common legal hurdles faced.Footnote 22 Section 3 of the article then discusses recently decided cases and pending litigation in which rights arguments have been raised, and sometimes successfully deployed, to force greater action by states to address climate change. It identifies two key uses of rights-based claims by courts in climate change cases: firstly, as the basis for findings that defendants’ actions or omissions with regard to climate change potentially give rise to rights violations; or, secondly, as an interpretative tool that assists courts in finding breaches of other legal obligations, such as those in tort, in violation of a statutory obligation, or under the public trust doctrine. Section 4 analyzes the scope for further development of rights-based climate claims in other jurisdictions, drawing on the model offered by decided and ongoing climate change litigation in which rights arguments feature. Section 5 concludes with a consideration of the likely future role of rights-based cases in climate change jurisprudence.


Global warming should be seen not as an environmental crisis but as a human rights issue that risks the lives, livelihoods and homes of millions of people.

A succession of weather-related disasters around the world – from Superstorm Sandy, Typhoon Haiyan and Cyclone Pam to massive floods in Pakistan, crippling drought in Ethiopia and heatwaves in central Europe – have highlighted the human cost of climate change.Footnote 24 In developed countries, such events cause extensive damage to property and infrastructure, injury and, in some instances, loss of life.Footnote 25 The death toll from extreme weather disasters is often greater in developing countries, where events like severe storms, floods or droughts may also destroy housing, threaten food supplies and access to clean water, and deprive people of their livelihoods.Footnote 26 These weather-related disasters – predicted to become more frequent and severe with climate changeFootnote 27 – have obvious implications for the realization of fundamental human rights.

In this section, we briefly survey the growing international recognition of human rights–climate change linkages in the United Nations (UN) human rights system and under the international climate change regime. However, acknowledgement of the potential for climate change to affect the enjoyment of human rights does not translate readily into a strong legal claim for rights violation. Early lawsuits that sought to hold public and private actors accountable for rights violations based on climate change-related harm have faced a number of hurdles that will continue to be pertinent for future efforts at rights-based climate change litigation.

2.1. Recognition of the Human Rights–Climate Change Linkage

It is only relatively recently that the relationship between climate change and human rights has become a sustained focus of international law and policy making.Footnote 28 The issue of human rights–climate change linkages was first taken up by the UN Human Rights Council (HRC) in 2008.Footnote 29 Council Resolution 7/23 expressed the body’s concern that ‘climate change poses an immediate and far-reaching threat to people and communities around the world and has implications for the full enjoyment of human rights’.Footnote 30 At the same time, the HRC commissioned the Office of the UN High Commissioner for Human Rights (OHCHR) to prepare a study on human rights and climate change.

This seminal OHCHR study, released in January 2009, noted broad international agreement that climate change has generally negative effects on the realization of human rights.Footnote 31 Although the universal human rights treaties – such as the International Covenant on Civil and Political Rights (ICCPR)Footnote 32 and the International Covenant on Economic, Social and Cultural Rights (ICESCR)Footnote 33 – do not include a specific right to a safe and healthy environment that might be compromised by climate change, the study emphasized that all UN human rights treaty bodies recognize the intrinsic link between the environment and realization of a range of human rights.Footnote 34 These include individual rights to life,Footnote 35 health,Footnote 36 food,Footnote 37 water,Footnote 38 and adequate housing,Footnote 39 as well as the collective right to self-determinationFootnote 40 and procedural rights concerning access to information and participation in decision making regarding environmental risks.Footnote 41 As the OHCHR study recognized, weather-related disasters exacerbated by climate change have the potential to affect human rights broadly, for instance, by giving rise to deaths, disease or malnutrition (right to life, right to health), threatening food security or livelihoods (right to food), impacting upon water supplies and compromising access to safe drinking water (right to water), destroying coastal settlements through storm surge (right to adequate housing), and in some cases forcing relocation as traditional territories become uninhabitable (right to self-determination).Footnote 42 The study also highlighted the linkages between climate change harm and threats to international peace and securityFootnote 43 – an issue that has attracted growing international and domestic attention in subsequent years.Footnote 44

In addition to the general implications of climate change for human rights, the OHCHR study noted that impacts are unevenly distributed. Hence, climate change impacts are likely to be ‘felt most acutely by those segments of the population who are already in vulnerable situations due to factors such as poverty, gender, age, minority status, and disability’.Footnote 45 In countries with low capacity to adapt to climate change, particular risks exist for women, children and indigenous peoples. These findings were affirmed in HRC Resolution 10/4 (2009) and echoed in subsequent resolutions, including the 2015 HRC Resolution on Human Rights and Climate Change.Footnote 46

In the international climate regime under the auspices of the UN Framework Convention on Climate Change (UNFCCC), the impacts of climate change on individuals and communities have also received more attention in recent years, in tandem with developments in the UN human rights bodies. At the 16th Conference of the Parties (COP) to the UNFCCC in Cancún (Mexico) in 2010, the COP took note of HRC Resolution 10/4:

which recognizes that the adverse effects of climate change have a range of direct and indirect implications for the effective enjoyment of human rights and that the effects of climate change will be felt most acutely by those segments of the population that are already vulnerable owing to geography, gender, age, indigenous or minority status, or disability’.Footnote 47

The Cancún Agreements also affirmed the importance of addressing adaptation ‘with the same priority as mitigation’,Footnote 48 and recognized the need ‘to strengthen international cooperation and expertise in order to understand and reduce loss and damage associated with the adverse effects of climate change, including impacts related to extreme weather events and slow-onset events’.Footnote 49

A greater focus in the international climate regime on ‘adaptation’ (i.e., the ‘process of adjustment to actual or expected climate and its effects’)Footnote 50 and ‘loss and damage’ (essentially, those climate change impacts which cannot be avoided through adaptation)Footnote 51 has inevitably directed more attention to how individuals and communities are affected by climate change, and their relative adaptive capacity.Footnote 52 This emphasis has brought the climate change regime into closer alignment with international efforts on sustainable development, disaster management, and human rights protection.Footnote 53 Such linkages were the focus of intense lobbying efforts in the lead-up to the UNFCCC Paris negotiations in December 2015, with strong support offered by the UN OHCHR and the Special Rapporteur on Human Rights and the Environment, John Knox.Footnote 54 While the final text of the Paris Agreement did not mention human rights in its operative provisions as many had hoped, it included the following preambular reference:

Acknowledging that climate change is a common concern of humankind, Parties should, when taking action to address climate change, respect, promote and consider their respective obligations on human rights, the right to health, the rights of indigenous peoples, local communities, migrants, children, persons with disabilities and people in vulnerable situations and the right to development, as well as gender equality, empowerment of women and intergenerational equity.Footnote 55

The Paris Agreement also includes significant provisions on adaptation and, for the first time, a self-standing article dealing with loss and damage.Footnote 56 When coupled with the long-term temperature goal of remaining ‘well below’ 2 degrees Celsius (°C) and ‘pursuing efforts to limit the temperature increase to 1.5°C above pre-industrial levels’ – goals which themselves acknowledge the importance of significantly reducing ‘the risks and impacts of climate change’Footnote 57 – the Paris Agreement arguably reflects recognition of the need to safeguard the interests of the most vulnerable people and communities as part of the global climate change response. Writing in the aftermath of the negotiations, Special Rapporteur Knox summarized this view, concluding that ‘the Paris Agreement signifies the recognition by the international community that climate change poses unacceptable threats to the full enjoyment of human rights and that actions to address climate change must comply with human rights obligations’.Footnote 58

2.2. Lessons from Early Rights-Based Climate Change Litigation

Growing recognition of the ways in which climate change implicates human rights has been significant not only as a driver of greater integration in these previously separate international agendas, but also ‘because it provides a tangible legal framework for analyzing state actions that lead to climate change’.Footnote 59 Looking at climate change through a rights lens can aid in framing proactive strategies to try to pre-empt human harm, as well as responses to climate change-related disasters ex post.Footnote 60 Although the implications of climate change for the realization of human rights are increasingly obvious, the more difficult issue that arises is whether the effects of climate change on human rights provide evidence of an actionable rights violation.Footnote 61 As highlighted by the OHCHR study, discussed above, claimants in rights-based climate change litigation face several hurdles. These include:

  • establishing causal links between a country’s GHG emissions, or failures in adaptation policies, and specific climate change impacts, which in turn adversely affect human rights;

  • specifically attributing human rights effects to climate change, especially where climate change also causes other social, economic and political types of harm;

  • using predictions of future climate change impacts to found claims of human rights violations, which are more normally established after actual harm has occurred;Footnote 62 and

  • applying rights protections extraterritorially with regard to actions occurring outside the state(s) in which the effects are most acutely felt.Footnote 63

Early rights-based climate litigation, which preceded decisions such as that in the Leghari case, struggled with these obstacles. A good illustration is provided by the 2005 petition filed with the Inter-American Commission on Human Rights (IACHR) on behalf of the Inuit indigenous people of the US and Canada, which was the first international attempt to frame a claim for redress for climate change harm in human rights terms.Footnote 64 The Inuit petition set out in great detail how climate change is already interfering with, and will further compromise, the Inuit’s human rights as a result of increasing temperatures and earlier melting of the snow and sea ice on which their culture, identity and economy depend. The petition drew on the human rights protections under the American Declaration on the Rights and Duties of Man,Footnote 65 as well as other international instruments, including rights to life, health, property, cultural identity and self-determination.Footnote 66

At the heart of the petition was the Inuit’s claim that the US – as the largest contributor to global GHG emissions at the time, with limited efforts to reduce emissions under the administration of President George W. Bush – was internationally responsible for rights violations brought about by climate change in the Arctic. The petition sought to establish causal links between acts and omissions of the US government and violation of Inuit human rights through climate change on a number of bases. The petitioners pointed to the scientific consensus on the links between increasing global temperatures and anthropogenic GHG emissions accepted even by the US government,Footnote 67 the role of the US as the largest emitter of GHGs at the time,Footnote 68 its refusal to ratify the Kyoto ProtocolFootnote 69 and to introduce domestic measures to control and reduce emissions,Footnote 70 and the fact that the US decision to persist with unregulated emissions of GHGs from its territory was taken in full knowledge of the radical impacts of climate change for the Arctic environment on which the Inuit depend for cultural survival.Footnote 71 The petition requested the IACHR to issue a report finding the US responsible for violations of the Inuit’s human rights and recommending that the country adopt mandatory measures to limit its GHG emissions and cooperate in global efforts to that end.Footnote 72

However, in a brief response to the Inuit petition, the IACHR found it was not possible ‘at present’ to process the complaint. The Commission indicated that ‘the information provided does not enable us to determine whether the alleged facts would tend to characterize a violation of the rights protected by the American Declaration’.Footnote 73 As a legal intervention designed to protect the Inuit’s human rights and to generate action on climate change, the IACHR petition failed. Yet it still had considerable impact. The Commission agreed to hold a subsequent hearing on the connections between climate change and human rights, which has been identified as a factor that helped to put the issue on the agenda of UN human rights bodies.Footnote 74 The case also received media coverage, which drew attention to the problems faced by the Inuit.Footnote 75

Despite the lack of formal success achieved by rights-based climate change cases in the past, the enhanced international profile of human rights–climate change linkages over the last decade, together with the growth of a body of jurisprudence on the implications of general environmental degradation and natural disasters for the protection of human rights, has encouraged a continued focus on the possibilities for rights-based claims in climate change litigation.Footnote 76 The following section examines the Leghari and Urgenda decisions in 2015, as well as other recent cases that have raised rights arguments, in order to evaluate the jurisprudential step forward that they may represent.


Climate change is a defining challenge of our time and has led to dramatic alterations in our planet’s climate system. For Pakistan, these climatic variations have primarily resulted in heavy floods and droughts, raising serious concerns regarding water and food security. On a legal and constitutional plane this is clarion call [sic] for the protection of fundamental rights of the citizens of Pakistan, in particular, the vulnerable and weak segments of the society who are unable to approach this Court.

Leghari v. Federation of Pakistan,

Order of 4 Sept. 2015, Lahore High Court,

Judge Syed Mansoor Ali ShahFootnote 77

The lead-up to and aftermath of the Paris climate change negotiations saw the emergence of a new suite of climate change cases in which petitioners have framed their claims, at least partly, in rights terms. These cases illustrate both a greater willingness on the part of litigants to attempt human rights arguments in a climate context, and also a growing receptivity of courts to this approach. The following sections examine the rights-based arguments advanced in the Urgenda and Leghari decisions, as well as those in more recent cases in other jurisdictions such as the US, the Philippines, Austria and South Africa. These cases suggest new avenues for rights-based claims to challenge government and corporate climate action, whether as the basis for a finding of rights violation or as a supplement to arguments that seek to establish breach of other legal obligations. While these decisions – all issued by lower-level national courts – represent a trickle rather than a flood, and must each be assessed within the particular socio-legal context in which they arise, they nonetheless point the way to how rights-based climate suits may be successfully framed and highlight the strategies that might be deployed to overcome hurdles raised in earlier cases. Our preliminary assessment is that these cases may represent the beginnings of a ‘rights turn’ in climate change litigation that is likely to inspire similar lawsuits in other countries, especially those with similarly framed laws and court access. However, the vast majority of cases around the world are likely to continue to be statutory claims.

3.1. Urgenda v. The Netherlands

The Urgenda case catapulted to international public attention with the ruling of the Hague District Court on 24 June 2015.Footnote 78 The Court held that the emissions reduction efforts of the Dutch government were inadequate judged against the norm of 25 to 40% for developed countries urged by climate science and international climate policy. The Court ordered the Dutch government to ensure that national GHG emissions by the year 2020 are at least 25% below 1990 levels.Footnote 79 Although an appeal has been lodged against the Court’s decision,Footnote 80 in the interim and given that the 2020 deadline is fast approaching, the Dutch government has indicated that it will implement the District Court ruling.Footnote 81

The case before the Hague District Court was brought by UrgendaFootnote 82 on its own behalf and on behalf of 886 Dutch citizens who authorized the NGO to act in their stead. Urgenda invoked a range of legal bases for its claim, only one of which concerned human rights. Most of the Court’s decision focused on another of Urgenda’s arguments – namely, that the Dutch government owed a duty of care to the NGO, to the parties it represented, and to Dutch society more generally, which was breached by the government’s inadequate climate change mitigation policy. Urgenda also argued that, through its contribution to global GHG emissions, the Dutch government unlawfully exposed the international community to the risk of dangerous climate change, with the potential for irreversible damage to human health and the environment. The Court ultimately upheld Urgenda’s claim that the state’s 2020 emissions reduction target was inadequate judged against the standards of climate science and international climate policy, and that this gave rise to a breach of a duty of care under Dutch law. While the content and scope of this duty of care was the focus of much of the Court’s judgment, additional human rights arguments put by the NGO also played a significant role in the analysis. In particular, the decision illustrates how such arguments were applied as an interpretative tool that assisted the Court in reaching its ultimate finding regarding the existence of a relevant duty of care and its breach.

The human rights arguments developed by Urgenda drew on the protection of the right to life (Article 2) and the right to home and family life (Article 8) under the European Convention on Human Rights (ECHR) to which the Netherlands is a party.Footnote 83 While the ECHR does not include an explicit right to a safe or healthy environment, the forms of protection in Articles 2 and 8 have been interpreted repeatedly by the European Court of Human Rights (ECtHR) as extending to situations of threatened environmental harm from hazardous activities and natural disasters.Footnote 84 To constitute a rights violation, the effects of the environmental harm concerned must generally be of a serious and direct nature.Footnote 85 In such cases, the state may be under a positive obligation to take measures to safeguard the rights of individuals from such harm.Footnote 86

Urgenda sought to extend the environmental rights jurisprudence of the ECtHR to the climate change context. It contended that the failure of the state to take adequate measures to safeguard its citizens from climate damage constituted a violation of the rights to life and to respect for home and family life. In this regard, the Urgenda claim parallelled the Inuit petition described in Section 2 above. As in the Inuit claim, the Court in Urgenda ultimately did not find that inadequacies in the Dutch climate mitigation policy breached human rights.Footnote 87 The Court ruled that Urgenda, as a legal rather than a natural person, could not be a victim of any breach and hence could not advance a claim of human rights violation on its own behalf. In relation to the 886 individual co-claimants, the Court held that it did not have sufficient information about how their interests were affected to rule on the issue of whether a rights violation had arisen.Footnote 88

While not finding a violation of rights in the case, the Court in Urgenda nonetheless indicated that rights arguments remained relevant to its analysis in other ways. In assessing the rights-based claims put forward by Urgenda, the Court adopted a similar approach to that applied in its analysis of the relevance of other international environmental obligations cited by Urgenda as a basis for liability on the part of the Dutch government. The Court found that Urgenda could not rely directly on these obligations to derive a right of action, but that they had a ‘reflex effect’ within national law such that they could be taken into account in applying or interpreting ‘national law open standards or concepts’.Footnote 89 Similarly, the Court found that the ECHR rights protections invoked by Urgenda, and their interpretation by the ECtHR, could ‘serve as a source of interpretation when detailing and implementing open private-law standards … such as the unwritten standard of care of Book 6, Section 162 of the Dutch Civil Code’.Footnote 90 The human rights standards held ‘meaning’ for the Court in assessing the question of whether the state had failed to meet its duty of care towards Urgenda.Footnote 91 Specifically, they informed the analysis of ‘what degree of discretionary power the State is entitled to in how it exercises the tasks and authorities given to it’ and ‘the minimum degree of care the State is expected to observe’.Footnote 92

The Court’s approach to rights-based claims in the case might be summarized as that of using human rights as an interpretative tool in analyzing Urgenda’s primary contention of breach of a duty of care. Exactly how human rights are to be used in this way was not made clear by the Court, although the judgment offers a few clues. For instance, at several points in its findings the Court described climate change in terms which referenced its impacts on human communities: a ‘highly hazardous situation for man and the environment’,Footnote 93 ‘a global hazard that could result in an impaired living climate in the Netherlands’,Footnote 94 and a problem with ‘serious consequences for man and the environment, both in the Netherlands and abroad’.Footnote 95 The nature and the extent of the damage ensuing from climate change were also factors taken into account by the Court in determining whether the state exercised the due standard of care through its current climate policy.Footnote 96 It held:

If, and this is the case here, there is a high risk of dangerous climate change with severe and life-threatening consequences for man and the environment, the State has the obligation to protect its citizens from it by taking appropriate and effective measures. For this approach, it can also rely on the aforementioned jurisprudence of the ECtHR.Footnote 97

Arguably, the Court also took human rights into account in judging between the adequacy of mitigation and adaptation measures as a response to the risks posed by climate change. Its conclusion, after reviewing the available scientific evidence, was that mitigation was ‘vital for preventing dangerous climate change’ as adaptation measures would ‘not be sufficient to protect citizens against the aforementioned consequences [of climate change] in the long term. The only effective remedy against hazardous climate change is to reduce the emission of greenhouse gases’.Footnote 98

3.2. Leghari v. Pakistan

Compared with the media storm that followed in the wake of the Urgenda ruling, the decision of the Lahore High Court in Pakistan in the Leghari case caused barely a ripple.Footnote 99 The ruling of the Lahore High Court, however, is no less innovative and is potentially more transformative than the decision in Urgenda. Unlike the Urgenda judgment, the Leghari case represents a successful use of rights arguments as the legal foundation of a climate change suit. Moreover, its focus on government inaction to address adaptation challenges ties in far more closely with the human consequences of climate change than the technical discussion of carbon budgets and emissions targets that dominated the Urgenda hearing. Building adaptive capacity and reducing vulnerability to climate change is also generally regarded as a national and local government responsibility, with failures to take adaptation measures more clearly linked to harm to the nation’s populace. These features of the Leghari case point to its potential as a model for future rights-based, adaptation-focused litigation, although whether courts in other jurisdictions would be as receptive to such claims as Pakistan’s traditionally activist judiciary is more open to question.Footnote 100

The petitioner in the case, Mr Ashgar Leghari, was described in the orders of the Court as an ‘agriculturalist’ with a livelihood dependent on farming.Footnote 101 Leghari brought his case before the Court using public interest litigation – a concept well-established in Pakistani jurisprudence as providing an exception to common law locus standi rules in order to allow the enforcement of the fundamental rights protected under Pakistan’s Constitution in respect of a group or a class of people, such as the poor or other vulnerable groups.Footnote 102 Leghari submitted that climate change posed a serious threat to water, food, and energy security in Pakistan, and hence offended fundamental rights safeguarded under Pakistan’s 1973 Constitution, including the right to life (Article 9), the right to dignity of person and privacy of home (Article 14), and the right to property (Article 23).Footnote 103

The action of the state complained of in the case was inadequate implementation of the country’s National Climate Change Policy 2012Footnote 104 and supporting Framework for Implementation of Climate Change Policy (2014–2030).Footnote 105 Given Pakistan’s high vulnerability to climate change impacts – as evidenced by the devastating floods of 2010 and 2011 – the focus of the National Climate Change Policy is adaptation, including vulnerabilities across various sectors such as water, agriculture and forestry, and appropriate adaptation measures to address these vulnerabilities.Footnote 106 Adaptation and building climate resilience is similarly the focus of the Framework for Implementation concluded in November 2013. This document categorizes and prioritizes proposed adaptation measures to be taken by federal government departments and provincial and local authorities, with the most urgent items designated as ‘priority actions’ to be delivered ‘within 2 years’ (by 2016).Footnote 107 However, as the Joint Secretary of the newly reconstituted Ministry of Climate Change admitted frankly to the Court during the proceedings, despite various reminders to government departments to report on their progress in implementing adaptation measures, by and large the response was not positive and indicated a lack of awareness and sensitivity to the issue.Footnote 108 Representatives of various ministries – including those with responsibility for water and flood management, planning, forestry, agriculture, and disaster management – also made submissions to the Court, but these ‘could not satisfactorily show that adaptation measures as listed in the Framework were seriously afoot’.Footnote 109

In contrast to the ‘delay and lethargy’ of state agencies, the Lahore High Court in its order of 4 September 2015 saw climate change as ‘a defining challenge’ and a ‘clarion call for the protection of fundamental rights of the citizens of Pakistan, in particular, the vulnerable and weak segments of the society who are unable to approach this Court’.Footnote 110 According to the Court, the failure of Pakistani governmental authorities to implement the national climate policy framework in a timely fashion ‘offends the fundamental rights of the citizens which need to be safeguarded’.Footnote 111 It identified various rights and principles that supported this conclusion, including:

  • ‘[f]undamental rights, like the right to life (Article 9) which includes the right to a healthy and clean environment and right to human dignity (Article 14);’ and

  • [c]onstitutional principles of democracy, equality, social, economic and political justice that included ‘within their ambit and commitment’ the international environmental principles of sustainable development, the precautionary principle, environmental impact assessment, inter- and intragenerational equity and the public trust doctrine.Footnote 112

The Court also explicitly – and more fully than has been seen in earlier climate change cases around the world – identified a principle of climate change justice. Past traditions of environmental justice, it said, which were ‘largely localized’, needed to move to climate change justice in recognition of this ‘more urgent and overpowering’ problem.Footnote 113 The Court saw fundamental rights as lying ‘at the foundation of these two overlapping justice systems’.Footnote 114

Taking an activist approach, which has become a feature of many judicial opinions in Pakistan and neighbouring India,Footnote 115 the Lahore High Court not only found breaches of legal provisions regarding fundamental rights but also went on to design judicially administered machinery for remedying those breaches.Footnote 116 It held that:

[the r]ight to life, right to human dignity, right to property and right to information under articles 9, 14, 23 and 19A of the Constitution, read with the constitutional values of political, economic and social justice, provide the necessary judicial toolkit to address and monitor the Government’s response to climate change.Footnote 117

The Court order of 4 September 2015 directed relevant ministries, departments, and authorities to nominate a climate focal person to liaise closely with the Ministry of Climate Change to ensure implementation of the Framework and, out of the priority actions listed in the Framework, to present a list of adaptation action points by the end of 2015.Footnote 118 Further, to assist the Court in monitoring the departments’ progress in implementing the Framework, the Court ordered the establishment of an expert climate change commission comprising representatives of the key government ministries, NGOs, and technical experts.Footnote 119

A mere ten days later, on 14 September 2015, Judge Syed Mansoor Ali Shah of the Lahore High Court had before him, as ordered, 18 representatives from federal and provincial authorities and a list of their nominated ‘focal persons’ for liaison with the Ministry of Climate Change. The Court order of 14 September reiterated that ‘climate change is no longer a distant threat’ for Pakistan,Footnote 120 but the judge opined, after listening to the government representatives appearing before him, that ‘no material exercise has been done on the ground to implement the Framework’.Footnote 121 The Court consequently decided to establish a Climate Change Commission to ‘expedite the matter and to effectively implement the fundamental rights of the people of Punjab’.Footnote 122 This Commission will have the responsibility for selecting and implementing adaptation priorities in a way that respects fundamental rights of citizens to be safeguarded from climate harms that affect those rights.Footnote 123

3.3 Other Recent Domestic Climate Litigation Invoking Rights Arguments

A number of other recent, domestic climate change cases have advanced rights arguments, further reinforcing the jurisprudential trend initiated by the Urgenda and Leghari decisions. Rights have been invoked in one of two ways, which parallel the approaches taken by the petitioners in Urgenda and Leghari. In the Juliana case in the US, and in a complaint before the Commission on Human Rights in the Philippines, the petitioners argue that the failure of the defendants to reduce GHG emissions adequately, and hence avoid the worst effects of climate change, is in breach of the petitioners’ constitutional rights. Neither of these actions has reached the merits phase, which makes it difficult to predict how decision makers might ultimately rule, although in the US context commentators have highlighted the numerous obstacles to a successful constitutional rights claim.Footnote 124 In other climate-related cases recently decided by courts in Austria and South Africa, rights arguments were deployed as a factor in evaluating other legal claims. Rulings in the plaintiffs’ favour in both cases provide further evidence of the growing receptivity of courts of rights arguments in a climate context, particularly where rights are used as an interpretative tool to analyze the operation of other legal obligations.

Allegations of Rights Violations: US and Philippines Cases

The case of Juliana v. United States Footnote 125 represents a novel iteration in a wave of US lawsuits brought in the last few years based on arguments that government failures to adequately constrain GHG emissions breach a public trust obligation to safeguard natural resources in the public interest.Footnote 126 The organizing force behind this litigation is Our Children’s Trust, a group formed ‘to elevat[e] the voice of youth to secure the legal right to a stable climate and healthy atmosphere for the benefit of all present and future generations’.Footnote 127 In the Juliana case against the US government, public trust arguments are again being advanced by the youth plaintiffs involved, but this time are coupled with claims that the defendants’ actions in failing to adequately mitigate climate change violate the substantive due process rights of the petitioners to life, liberty and property, as safeguarded in the US Constitution.Footnote 128 The plaintiffs are seeking a declaration that their constitutional and public trust rights have been violated, and an order enjoining the defendants to refrain from violating those rights and directing them to develop a plan to reduce carbon dioxide (CO2) emissions.Footnote 129

Decisions issued so far in the Juliana case do not engage directly with the merits of the constitutional rights claims. On 10 November 2016, Judge Ann Aiken of the US District Court for the District of Oregon issued an opinion and order rejecting the motions of the US government and fossil fuel industry to dismiss the action. This preliminary decision confirmed that the plaintiffs have a justiciable case and standing to pursue their case at trial. A threshold question for the court was whether there was a fundamental liberty right at issue in the claim, which in US constitutional law on due process rights determines the applicable level of judicial scrutiny. A fundamental right can be another enumerated constitutional right or an unenumerated right deeply rooted in history or tradition, or fundamental to the scheme of ordered liberty, the understanding of which may change over time. In her judgment, Judge Aiken determined the existence of a new fundamental right: ‘the right to a climate system capable of sustaining human life’. Her opinion noted that ‘a stable climate system is quite literally the foundation “of society, without which there would be neither civilization nor progress.”’Footnote 130 Accordingly, the Court found that:

where a complaint alleges governmental action is affirmatively and substantially damaging the climate system in a way that will cause human deaths, shorten human lifespans, result in widespread damage to property, threaten human food sources, and dramatically alter the planet’s ecosystem, it states a claim for a due process violation.Footnote 131

In March 2017, the US government (now under the administration of President Trump) and fossil fuel industry intervenors requested – in an unusual interlocutory appeal – that the US District Court for the District of Oregon allow the Ninth Circuit Court of Appeals the opportunity to review Judge Aiken’s order before the trial takes place. The defendants also requested that the appeal be expedited, and that the trial be put on hold if the appeal is granted. The Juliana plaintiffs resisted this motion, arguing that any delay in getting to trial would irreversibly prejudice the youth in securing and protecting their fundamental constitutional rights. In a decision issued on 1 May 2017, US Magistrate Judge Thomas Coffin recommended the denial of the defendants’ requests.Footnote 132 In his findings and recommendations, the Judge indicated the potential for this landmark case to:

define the contours of plaintiffs’ constitutional rights to life and a habitable atmosphere and climate, declare the levels of atmospheric CO2 which will violate their rights, determine whether certain government actions in the past and now have and are contributing to or causing the constitutional harm to plaintiffs, and direct the federal defendants to prepare and implement a national plan which would stabilize the climate system and remedy the violation of plaintiffs rights.Footnote 133

His recommendations and findings also cautioned that the defendants and intervenors ‘underestimate the nature of the danger allegedly created by their actions’,Footnote 134 which would be better fleshed out by the taking of evidence in trial. This ruling, although open to further review, would seem to lessen considerably the chances of the defendants’ interlocutory appeal succeeding, and pave the way for the case to proceed to trial.Footnote 135

Like the Juliana case and the Leghari decision in Pakistan, the complaint currently being considered by the Commission on Human Rights in the Philippines alleges violations of rights protections as a result of climate change-linked extreme weather disasters to which the defendants’ actions have contributed.Footnote 136 The petition, filed by Greenpeace together with groups and individuals in the Philippines, is unusual in targeting private actors – the 50 largest fossil fuel companies known as ‘carbon majors’.Footnote 137 It calls for ‘a comprehensive investigation into the responsibility of the Carbon Majors for violations or threats of violations of human rights resulting from the impacts of climate change,’Footnote 138 drawing on principles articulated in the UN Guiding Principles on Business and Human Rights.Footnote 139 The petition also alleges responsibility on the part of states where carbon majors are incorporated on the basis that such countries have a customary international law duty to prevent harm by ensuring that these companies refrain from the activities that interfere with the rights of Filipinos.Footnote 140 The petition was accepted by the Philippines Commission on Human Rights in December 2015 during the Paris Agreement negotiations. The Commission subsequently requested the companies named in the petition to respond by the end of September 2016, which resulted in some fossil fuel companies – such as Exxon, Shell and Peabody – challenging the Commission’s jurisdiction and filing motions to dismiss the complaint.Footnote 141 While these jurisdictional challenges are ongoing, the Commission has nonetheless moved forward with a national inquiry, which is significant as this procedure is only used (rarely) for matters of great importance to the country and its citizens.Footnote 142

Rights as an Interpretative Tool: Austrian and South African Cases

Recent decisions of courts in Austria and South Africa illustrate an alternative pathway for rights arguments in climate change litigation, which bears some similarities to the use made of rights claims in the Urgenda case. In both cases, the plaintiffs challenged authorizations granted for emissions-intensive projects. In the Austrian case, at issue was the Lower Austrian government’s approval for a third runway at the Vienna-Schwechat international airport. In the South African case, the decision challenged was that of the Minister of Environmental Affairs to issue an environmental authorization for a new coal-fired power station before completion and consideration of a climate change impact assessment as part of the overall environmental impact assessment (EIA) for the project. Rights in both these cases were advanced as a supplement to the primary claims focused on government compliance with statutory obligations.

In the Third Runway at Vienna International Airport case,Footnote 143 the rights provisions argued before Austria’s Federal Administrative Court (Bundesverwaltungsgericht) included Article 37 of the Charter of Fundamental Rights of the European Union (CFREU), which calls for a ‘high level of environmental protection and the improvement of the quality of the environment’ to be integrated into EU policies and ‘ensured in accordance with the principle of sustainable development’;Footnote 144 provisions of the Austrian Federal Constitution committing the state to the principle of sustainability and to comprehensive environmental protection;Footnote 145 and provisions of the Lower Austrian Provincial Constitution, which contain state commitments to ensuring adequate living conditions and which make specific reference to environmental and climate protection.Footnote 146

The Court held that these rights provisions, directed primarily at legislators, were relevant as an interpretive aid in seeking to interpret undefined legislative requirements such as the notion of the ‘public interest’.Footnote 147 In evaluating where the balance of public interest lay in respect of the runway application, the Court weighed potential public benefits (such as accommodating increased flights, promoting economic development and job creation) against the public interest in avoiding negative impacts, including environmental harm and growth in GHG emissions contributing to climate change. The Court noted that climate change in Austria is already under way and will have broad, major impacts on people, animals, plants and the entire environment. Ultimately it ruled that the construction and operation of a third runway at the Vienna international airport would be contrary to the public interest in environmental protection, and climate protection in particular.

In the South African case, Earthlife Africa Johannesburg v. Minister for Environmental Affairs and Others,Footnote 148 Earthlife’s arguments centred on the contention that, on the proper interpretation of the EIA legislation at issue, a climate change impact assessment was mandatory before issue of an environmental authorization for a new coal-fired power station, despite the lack of an express legislative requirement for such an assessment.Footnote 149 In support of this construction, the NGO contended that the relevant legislative requirement should be interpreted in the light of various domestic and international instruments, including section 24 of the South African Constitution, which enshrines a right to environment. Section 24 provides:

Everyone has the right –

(a) to an environment that is not harmful to their health or well-being; and

(b) to have the environment protected, for the benefit of present and future generations, through reasonable legislative and other measures that –

(i) prevent pollution and ecological degradation;

(ii) promote conservation; and

(iii) secure ecologically sustainable development and use of natural resources while promoting justifiable economic and social development.Footnote 150

Although the Earthlife decision turned largely on the interpretation of the relevant statutory provisions in the course of judicial review, the Court also noted its constitutional obligation, when interpreting legislation that implicates or affects rights protected in the Constitution’s Bill of Rights, to promote the purport, spirit and objects of the Bill of Rights in the interpretation process.Footnote 151

The Court commented:

Section 24 recognises the interrelationship between the environment and development. Environmental considerations are balanced with socio-economic considerations through the ideal of sustainable development. This is apparent from section 24(b)(iii) which provides that the environment will be protected by securing ecologically sustainable development and use of natural resources while promoting justifiable economic and social development. Climate change poses a substantial risk to sustainable development in South Africa. The effects of climate change, in the form of rising temperatures, greater water scarcity, and the increasing frequency of natural disasters pose substantial risks. Sustainable development is at the same time integrally linked with the principle of intergenerational justice requiring the state to take reasonable measures to protect the environment ‘for the benefit of present and future generations’ and hence adequate consideration of climate change. Short-term needs must be evaluated and weighed against long-term consequences.Footnote 152

Beyond this paragraph, the Court did not explain specifically the significance of the constitutional environmental right for its analysis. Instead, after referring to the right together with relevant legislative obligations, policy requirements and other obligations such as South Africa’s international commitments under climate change treaties, it concluded:

[T]he legislative and policy scheme and framework overwhelming[ly] support the conclusion that an assessment of climate change impacts and mitigating measures will be relevant factors in the environmental authorisation process, and that consideration of such will best be accomplished by means of a professionally researched climate change impact report. For all these reasons, I find that the text, purpose, ethos and intra- and extra-statutory context of section 24O(1) of NEMA support the conclusion that climate change impacts of coal-fired power stations are relevant factors that must be considered before granting environmental authorisation.Footnote 153

While by no means a direct application of the South African environmental rights provision, this decision suggests that rights arguments were at least a relevant part of the ‘extra-statutory context’ taken into account by the Court in reaching its conclusion that an environmental authorization for a new coal-fired power station could not be issued without first having a proper assessment of the project’s climate change impacts.


We are standing for what is necessary to do. Ten years ago we would not have tried this but I think things are changing ... it’s more clear to a broad group we are heading to a catastrophe.

Marjan Minnesma, CEO, UrgendaFootnote 154

The decisions surveyed in the previous section provide an early indication of the potential power and effectiveness of rights arguments in climate change litigation in an era where human rights–climate linkages are increasingly recognized at both national and international levels. Are these cases just interesting one-offs or the beginnings of a novel transnational climate change jurisprudence that gives a significant role to rights-based claims in efforts to address climate change? As a scientific matter, six cases against a backdrop of hundreds of climate change cases brought in the last two decades are hardly statistically significant.Footnote 155 In addition, each of these cases originated in a very different socio-legal context, which inevitably shaped the resulting decisions. However, which arguments gain prominence in strategic litigation efforts, such as those ongoing in the climate sphere, is often based less on science than on litigators’ perception of what is currently ‘fashionable’ and what might gain favour in judicial eyes at any particular moment.Footnote 156 Moreover, the foundation for such cases will only become greater as climate change impacts worsen, especially if the US Trump administration’s decision to cease implementation of, and withdraw from, the Paris Agreement slows the pace of implementation and efforts to increase ambition.Footnote 157

With these caveats in mind, in this section we explore possibilities for future rights-based climate litigation globally, based on the cases that have emerged so far. Our focus is on those forums and jurisdictions where the available law and court structures would facilitate rights arguments in a climate change context, and where judiciaries are more likely to be receptive to these arguments. The most promising possibilities in this regard include, firstly, domestic constitutional rights litigation challenging government mitigation or adaptation failures; secondly, cases in European jurisdictions following the Urgenda model of using rights to question the adequacy of emissions reduction targets; and, thirdly, possibilities for human rights climate change claims under regional human rights treaties operating outside Europe.

4.1. Constitutional Rights Claims in a Climate Context

For climate advocates in countries with forms of constitutional rights protection that extend to safeguarding environmental health, the Leghari decision in Pakistan, as well as emerging cases in other jurisdictions, may serve as inspiration to explore options for enhancing adaptation (and mitigation) action by their home states using rights-based claims. The nature of constitutional rights protection and its enforceability vary markedly between countries,Footnote 158 as does the extent to which they mirror human rights protection under international treaty law.Footnote 159 Nonetheless, both the Leghari case and the ongoing litigation in the Juliana case illustrate the ways in which non-environmentally focused rights protection – such as rights to life, health, property and privacy (or family) – may be extended to encompass claims based on impacts brought about by climate change.

Alone, the existence of a constitutional right to a healthy environment (or safe climate)Footnote 160 is an insufficient indicator of the likely success of deploying rights arguments in climate litigation. Other factors relevant to the success of such arguments might include, firstly, the existence of legislation or procedures that facilitate the bringing of rights claims; and, secondly, existing case law or judicial practice that indicates receptivity towards novel argumentation, especially on environmental or other public interest issues. Applying these criteria, a 2014 report of the Environmental Law Alliance identified India, Brazil, Columbia, Ecuador, Kenya and Mexico as among potential hotspots for constitutional rights-based claims for climate damage.Footnote 161 Moreover, some countries – such as Pakistan, India and the Philippines – have an established track record of judicial activism in public interest environmental cases that could pave the way for liberal interpretations of constitutional rights protection in a climate context (as occurred in Leghari).Footnote 162

For potential litigants considering these types of claim, the most straightforward application of constitutional rights protection in a climate change context is likely to be to address governmental failures with respect to adaptation.Footnote 163 This was the case in Leghari, where inadequate action to prepare for climate change impacts led to a situation that was found directly to affect rights. Rights claims focused on adaptation have the advantage that the causal link between governmental action (or inaction) and climate change impacts on citizens that implicate their rights is generally easier to establish than in cases involving failure to mitigate. Moreover, issues of extraterritoriality do not arise, given that petitioners would be taking action against their own governments to force greater adaptation efforts in order to safeguard their rights.

By contrast, the constitutional rights-based climate claims brought so far to address mitigation failures – such as the Austrian Third Runway case, the Earthlife Africa case, the Philippines petition and the Juliana case – illustrate the more complex task that confronts claimants in developing rights arguments as part of a challenge to emissions-intensive projects or policies. Here, courts may also have to weigh competing arguments about the economic benefits of GHG-producing activities (for example, for economic development or energy security), the global nature of the climate change problem, and the extent to which a particular project or actor contributes to that larger problem. In these circumstances, use of rights arguments as a supplementary tool to buttress other legal claims may be a more successful strategy than seeking to establish a violation of rights protection.

4.2. Replicating the Urgenda Model in Other European Countries

The Urgenda decision has spurred much debate about the potential for similar litigation in other countries.Footnote 164 The Urgenda case itself followed arguments set out in Roger Cox’s book, Revolution Justified, designed to hold governments accountable for inadequate action on climate change. The work focused on human rights pathways and options for establishing a duty of care.Footnote 165 It was written with a view to initiating other cases similar to the Urgenda lawsuit.

The possibility for replicating the human rights arguments put forward in Urgenda in a new wave of litigation is geographically limited to other European countries that are parties to the regional ECHR. Similar claims are apparently being pursued in at least one Urgenda-inspired case in Belgium.Footnote 166 The potential for successful legal claims will depend on many factors, including how the ECHR is implemented in particular European state parties (for instance, does the treaty have direct effect in domestic law?), whether NGO petitioners can be considered victims or make claims of injury to human rights, and what legal avenues are available under domestic law for the enforcement of human rights. More generally, the stringency of a country’s access to justice laws – and the receptivity of its courts to novel (and potentially politically controversial arguments) – are also likely to be critical. As in Urgenda, litigants may achieve greater success with arguments that seek to use rights as part of the interpretative process in evaluating other legal obligations relating to a duty of care.

4.3. Actions under Regional Human Rights Instruments

Claims made before regional human rights tribunals offer another avenue for climate advocates seeking to pursue rights-based claims. This potential avenue for redress was utilized by the Inuit in their original climate change petition to the IACHR. The Arctic Athabaskan Peoples have since filed another petition with the IACHR, alleging human rights violations as a result of emissions of black carbon by Canada.Footnote 167 Like the Inuit petition, this latter petition is likely to face some ‘significant challenges’ although, arguably, advances in climate science and in climate jurisprudence since the 2005 petition offer hope for a better result.Footnote 168

Among the regional human rights tribunals, the ECtHR is by far the most well-established with the most extensive jurisprudence on the linkages between human rights and environmental protection. Although the ECtHR has not recognized a freestanding right to a healthy environment,Footnote 169 it has found that environmental risks can threaten other human rights protections, such as the right to life and the right to respect of private and family life,Footnote 170 as well as procedural rights like the right of access to information or to an effective remedy.Footnote 171 In the case of Budayeva v. Russia, the ECtHR found that Russia had violated its positive obligation to protect the right to life under the ECHR by failing to establish legislative and administrative frameworks to deter any threat to the right to life, including measures in that case to warn citizens of known natural disaster risks associated with mudslides.Footnote 172 Future climate cases might seek to extend this jurisprudence to the situation of foreseeable climate disaster risks and harm, arguing a failure on the part of states to take adequate adaptation measures to avoid threats to rights.

The regional human rights systems in the Americas and Africa also offer the potential for climate litigation alleging breaches of environmental rights, and both tribunals have seen an increasing environmental caseload in recent years.Footnote 173 Article 11 of the San Salvador Protocol to the American Convention on Human Rights declares ‘the right to live in a healthy environment and to have access to basic public services’.Footnote 174 Similarly, the African Charter on Human and Peoples’ Rights includes the right of peoples ‘to a general satisfactory environment favourable to their development’.Footnote 175 The inclusion of environmental rights in these regional treaties gives scope to bring complaints of rights violations focused specifically on types of climate harm that endanger people’s environmental health and well-being.

The early case of Gbemre v. Shell Petroleum Development Company Nigeria Ltd and Others,Footnote 176 decided in 2005 by the Nigerian High Court, provides not only a potential template, but also a cautionary tale, in this respect. The case raised rights violations under the African Charter resulting from air pollution and environmental harm caused by the gas-flaring practices of oil companies in Nigeria. The plaintiffs also raised an argument that gas flaring leads to the emission of GHGs and contributes to adverse climate change that in turn could lead to the violation of protected rights. While the Federal High Court of Nigeria did not rule specifically on this point, it referred to the plaintiffs’ climate change argument in its judgment, potentially signalling some judicial receptivity to this approach.Footnote 177 However, this ruling has faced significant implementation challenges in Nigeria.Footnote 178

The enforceability of these regional environmental rights protections also remains a significant issue. The San Salvador Protocol has only 16 parties (which do not include the US).Footnote 179 The African Charter has better state coverage with 53 parties and the African Court on Human and Peoples’ Rights – in operation since 2005 – has a growing caseload,Footnote 180 but only a handful of cases before the Court have so far raised environmental claims.Footnote 181


Ito na lang ba ang aming kauuwian – ang magbilang, o mapabilang, sa mga biktima ng climate change? (Will this be our fate – to just count the victims of climate change or be counted among them?)

Petition to the Commission on Human Rights of the Philippines.Footnote 182

This article has considered emerging climate change litigation which pursues rights claims, arguing that the trend discernible from the limited number of cases so far shows an increased use of these arguments by litigants and a growing receptivity of courts towards human rights-based argumentation in climate change cases. With creative lawyering, a number of credible avenues beckon to take forward additional rights claims in climate change litigation, which could further consolidate these trends and emphasize the extent of the nascent ‘rights turn’. Indeed, in some jurisdictions, given the coincidence of available environmental rights protection with procedures that enable rights claims and judiciaries willing to entertain them, the prospects for rights-based climate change lawsuits look bright. In other jurisdictions – notably the US, in which traditional, statutory-based climate cases have dominated – rights claims in climate change cases face a much harder road,Footnote 183 although this has not deterred some litigants, such as the youth plaintiffs in the Juliana case.

These efforts to raise rights arguments in climate change litigation coincide with a period of increased international attention to human rights–climate linkages, including the preambular reference in the Paris Agreement. Efforts in individual countries to raise rights claims in climate litigation may also draw inspiration from work being done by international expert groups to develop transnational principles for climate change liability. Examples include the Oslo Principles on Global Climate Change Obligations,Footnote 184 which draw from international human rights law, environmental law, and tort law to articulate obligations of states and enterprises to address climate change through both mitigation and adaptation actions, and the efforts of a working group of the International Bar Association to develop a Model Statute on Climate Change Actions and Relief.Footnote 185 Initiatives such as these seek to articulate a practical legal framework for applying human rights principles in a climate change context that could be used by groups as the foundation for claims.

Of course, court victories are not the only measure of ‘success’ for litigation brought with the strategic purpose of promoting social and policy change with respect to climate change. Even ‘losing’ cases can have important flow-on effects through the ways in which they shape public dialogue, business attitudes and government action.Footnote 186 Although alleging rights violations in climate cases may not result in formally successful judgments, they may nevertheless garner media and public attention that elevate political discussions about climate change, highlight the plight of particular communities, bring to light mitigation or adaptation failures, and ultimately illuminate the ‘human face’ of climate disaster. In the final analysis, the strongest benefit from a turn towards rights arguments in climate change litigation may stem from these informal effects and the role they play in re-orienting and reframing the climate debate to one that emphasizes impacts on people. Such framing may ultimately prove to be more publicly and politically salient than scientific and technical arguments in motivating strong action to address the problem.Footnote 187

159 Constitutional or civil rights protection often draws on formulations of human rights in international law. The principal difference between constitutional/civil rights and human rights is that the latter are generally held to be fundamental rights intrinsic to human existence whereas the former are rights that are granted to citizens of states – or, as civil rights activist Malcolm X put it: ‘Civil rights means you’re asking Uncle Sam to treat you right.

163 It is possible that the utility of bringing an adaptation-focused rights claim in any particular case could depend upon the targeted government being one with some capacity to devote resources to climate adaptation and resilience building, and where the adaptation measures have the potential to ameliorate the kinds of climate risk faced by the population.
