The facts as submitted by the authors

2.1 The authors belong to the indigenous minority group of the Torres Strait Islands and live on the four islands of Boigu (Keith Pabai and Stanley Marama), Masig (Nazareth Warria; and Yessie, Genia, Ikasa, Awara, Santoi and Baimop Mosby), Warraber (Kabay and Tyrique Tamu; and Ted and Daniel Billy) and Poruma (Nazareth Fauid).Footnote ⁴ The indigenous people of the Torres Strait Islands, especially the authors who reside in low-lying islands, are among the most vulnerable populations to the impact of climate change.

2.2 The Torres Strait Regional Authority (TSRA), a government body, has stated that “the effects of climate change threaten the islands themselves as well as marine and coastal ecosystems and resources, and therefore the life, livelihoods and unique culture of Torres Strait Islanders.” The TSRA also noted that “even small increases in sea level due to climate change will have an immense impact on Torres Strait communities, potentially threatening their viability” and “large increases would result in several Torres Strait islands being completely inundated and uninhabitable.”Footnote ⁵

2.3 Sea level rise already caused flooding and erosion on the authors' islands, and higher temperature and ocean acidification produced coral bleaching, reef death, and the decline of seagrass beds and other nutritionally and culturally important marine species. According to the TSRA, in the Torres Strait region, sea level has risen at ~0.6 cm per year from 1993-2010 (compared to the global average of 3.2 mm/yr).

2.4 With respect to the impact of climate change on the islands, the village on Boigu – one of five communities particularly vulnerable to inundation – is flooded each year. Erosion has caused the shoreline to advance and has detached a small area from the island. On Masig, a cyclone in March 2019 caused severe flooding and erosion and destroyed buildings. The cyclone resulted in the loss of three metres of shoreline. Approximately one metre of land is lost every year. In addition, a tidal surge in recent years has destroyed family graves, scattering human remains. On Warraber, high tides and strong winds cause seawater to flood the village centre every two to three years. On Poruma, erosion has washed away much of the island's sand over the past few decades.

2.5 Sea level rise has caused saltwater to intrude into soil of the islands, such that areas previously used for traditional gardening can no longer be cultivated. On Masig, rising sea level has caused coconut trees to become diseased, such that they do not produce fruits or coconut water, which are part of the authors' traditional diet. Such changes make the authors reliant on expensive imported goods that they often cannot afford. Patterns of seasons and winds play a key role in ensuring the authors' livelihoods and subsistence but are no longer predictable. Precipitation, temperature and monsoon seasons have changed, making it harder for the authors to pass on their traditional ecological knowledge. Seagrass beds and dependent species have disappeared. While crayfish is a fundamental source of food and income for the authors, they no longer find crayfish in areas where coral bleaching has occurred.

2.6 Referring to the TSRA report, the authors predict that the severe impacts on their traditional ways of life and subsistence and culturally important living resources will present significant social, cultural and economic challenges; impacts on infrastructure, housing, land-based food production systems and marine industries; and health problems such as increased disease and heat-related illness.

2.7 The State party has failed to implement an adaptation programme to ensure the long-term habitability of the islands. Despite numerous requests for assistance and funding made to the state and federal authorities by or on behalf of the islanders, the State party has not promptly and adequately responded. Although some works were done on Boigu and Poruma between 2017 and 2018, many of the priority actions identified in the Torres Strait Regional Adaptation and Resilience Plan 2016-21 remain unfunded. As of now, there is no further government funding confirmed. Local authorities have taken a triage approach to save homes and infrastructure, and residents of Warraber and Masig have taken matters into their own hands, using green waste and debris to secure fragile coastal ecosystems from erosion.

2.8 The State party has also failed to mitigate the impact of climate change. In 2017, the State party's per capita greenhouse gas emissions were the second highest in the world. Those emissions increased by 30.72% between 1990 and 2016. The State party ranked 43^rd out of 45 developed countries in reducing its greenhouse gas emissions during that period. Since 1990, the State party has actively pursued policies that have increased emissions by promoting the extraction and use of fossil fuels, in particular thermal coal for electricity generation.

2.9 There are no available or effective domestic remedies to enforce their rights under articles 2, 6, 17, 24 and 27 of the Covenant. The authors' rights under the Covenant are not protected in the Constitution or any other legislation applicable to the federal Government. The High Court of Australia has ruled that state organs do not owe a duty of care for failing to regulate environmental harm.Footnote ⁶

Complaint

3.1 The authors claim that the State party has violated their rights under articles 2, read alone and in conjunction with articles 6, 17 and 27; and articles 6, 17 and 27, each read alone. They also claim violations of the rights of the named children under article 24 (1), read alone and in conjunction with articles 6, 17 and 27 of the Covenant. The State party has failed to adopt adaptation measures (infrastructure to protect the authors' lives, way of life, homes and culture against the impacts of climate change, especially sea level rise.) The State party has also failed to adopt mitigation measures to reduce greenhouse gas emissions and cease the promotion of fossil fuel extraction and use. As indicated in the Committee's general comment no. 36,Footnote ⁷ climate change is a matter of fundamental human rights.

3.2 The State party's obligations under international climate change treaties constitute part of the overarching system that is relevant to the examination of its violations under the Covenant.Footnote ⁸

Observations of the State party on admissibility and the merits

4.1 In its submission of 29 May 2020, the State party maintains that the communication is inadmissible. The alleged violations of international climate change treaties such as the Paris Agreement, and other international treaties such as the International Covenant on Economic, Social and Cultural Rights, are inadmissible ratione materiae because they are outside the scope of the present Covenant. Moreover, there is no basis for the authors' argument that international climate change treaties are relevant to the interpretation of the Covenant, because there are stark and significant differences between the Paris Agreement and the Covenant. The two instruments have different aims and scopes. 16 States that have signed the Agreement have not signed the Covenant. Accordingly, interpreting the Covenant through the Paris Agreement would be contrary to the fundamental principles of international law.Footnote ¹² The ordinary meaning of one treaty cannot be used to supplant the clear language of the Covenant.Footnote ¹³

4.2 The authors have not substantiated their claim that they are victims of violations within the meaning of article 1 of the Optional Protocol.Footnote ¹⁴ There is no evidence that the authors face any current or imminent threat of a violation of any of the rights they invoked.Footnote ¹⁵ Moreover, the authors have not shown any meaningful causation or connection between the alleged violations of their rights and the State party's measures or alleged failure to take measures. To demonstrate victim status, the authors must show that an act or omission by the State party has already adversely affected their enjoyment of a Covenant right, or that such an effect is imminent. By their own admission, the authors have not met that test. It is not possible, under the rules of State responsibility under international law, to attribute climate change to Australia. Relying on the Committee's position in Teitiota v. New Zealand, the State party asserts that the authors invoke a risk that has not yet materialized.Footnote ¹⁶

4.3 The authors' claims are also without merit. None of the alleged failures to take mitigation measures fall within the scope of the Covenant. It is not possible under international human rights law to attribute climate change to the State party.Footnote ¹⁷ As a legal matter, it is not possible to trace causal links between the State party's contribution to climate change, its efforts to address climate change, and the alleged effects of climate change on the enjoyment of the authors' rights. OHCHR has stated that “it is virtually impossible to disentangle the complex causal relationships linking historical greenhouse gas emissions of a particular country with a specific climate change-related effect, let alone with the range of direct and indirect implications for human rights,” and that “it is often impossible to establish the extent to which a concrete climate change-related event with implications for human rights is attributable to global warming.”Footnote ¹⁸

4.4 The authors' claims with respect to adaptation measures are also without merit, as the alleged adverse effects of climate change have yet to be suffered, if at all, by the authors. Nor are such alleged violations imminent.

4.5 The State party describes in detail the adaptation and mitigation measures it is taking with respect to climate change.Footnote ¹⁹ The TSRA coordinates climate change programs and policies for the benefit of the region and its communities. It consists of both an elected arm of 20 Torres Strait Islanders and Aboriginal representatives from the region, and an administrative arm with a Chief Executive Officer and staff who implement and manage TSRA programs. To respond to coastal management and climate change issues in the Torres Strait, the TSRA established a committee from 2006 to 2013. It included representatives from the communities worst affected by coastal erosion and inundation, including Boigu, Warraber, Masig and Poruma, as well as state and federal agencies and various research institutions. The committee enabled a whole-of-government, coordinated response to coastal and climate change issues in the Torres Strait region and secured funds to progress identified priority coastal works. The State party also describes in detail the Torres Strait Climate Strategy 2014–18, and the Torres Strait Regional Adaptation and Resilience Plan 2016–21. The TSRA continues to be, directly involved with communities in the Torres Strait to enable them to respond to climate change impacts.

4.6 TSRA also played a lead role in securing the information and funding to progress the construction of a new seawall for the low-lying island of Saibai. TSRA is working with local councils to progress a more detailed assessment of coastal hazards to inform coastal adaptation measures. TSRA also actively seeks opportunities to reduce the region's carbon footprint through the uptake of clean energy technologies.

Authors' comments on the State party's observations on admissibility and the merits

5.1 In their comments of 29 September 2020, the authors maintain that the State party did not challenge their arguments regarding several issues, including the science of climate change and its current and future impacts on the islands where they live; and the interdependency between the authors' unique and vulnerable culture and the surrounding ecosystem of the islands.

5.2 The State party erred in asserting that the adverse effects of climate change have yet to be suffered, if at all, by the authors. This contradicts the evidence that the authors already provided and the reports of the TSRA, a state agency. Moreover, the State party has already violated its duty to avert devastating and future irreversible impacts on rights protected by the Covenant, including impacts caused by existing greenhouse gas emissions. Protective measures must be initiated today.Footnote ²³ Climate change is a slow-onset process. Thus, a State party may violate its obligations before the worst effects occur. The authors' claims are based both on current violations and an imminent threat of violations. They already experience severe impacts from climate change, including disruption to their homes and family life. In their combined statements, the authors describe experiencing the following problems: flooding and inundation of villages; flooding and inundation of ancestral burial lands; loss by erosion of their traditional lands, including plantations and gardens; destruction or withering of traditional gardens through salinification caused by flooding or seawater ingress; decline of nutritionally and culturally important marine species caused by climate change, and associated coral bleaching (reef death) and ocean acidification; and a reduced ability to practice their traditional culture and pass it on to the next generation. They also experience anxiety and distress owing to erosion that is approaching some homes in the community. For six of the authors, upkeeping ancestral graveyards and visiting and feeling communion with deceased relatives is at the heart of their cultures, and the most important ceremonies (such as coming-of-age and initiation ceremonies) are only culturally meaningful if performed on the native lands of the community whose ceremony it is.

5.3 The authors living on Boigu and Masig face a real prospect of displacement and loss of culture within the next 10 years unless urgent and significant action is taken to enable the islands to withstand expected sea level rise. The authors living on Warraber and Poruma face such a prospect within their lifetimes unless urgent action is taken within 10-15 years. Such displacement can be prevented with reasonable adaptation and mitigation measures. If the State party's interpretation of imminence were followed, the authors would be forced to wait until their culture and land have been lost in order to submit a claim under the Covenant.

5.4 The authors have identified specific acts and omissions by the State party (relating to adaptation and mitigation) instead of relying on abstract arguments. Those acts and omissions have already and will continue to impair the authors' rights in ways that will worsen over time, because of the latent and/or irreversible nature of climate change.

5.5 The State party is responsible for its own emissions contribution, lack of due diligence, and failure to take adaptation measures to protect the authors' rights and fulfil its obligation to reduce emissions. The protection of the right to life requires States to review their energy policies and prevent the dangerous emission of greenhouse gases.

5.6 International environmental legal obligations of States are indeed relevant to interpreting the scope of their duties under the Covenant. Treaties should be interpreted in the context of their normative environment.

5.7 The State party has not so far taken any adequate concrete measures to prevent the authors' islands from becoming uninhabitable, or to address the real and foreseeable threat of the complete loss of the authors' cultures. The Committee's jurisprudence supports the notion that environmental harm can lead to violations of fundamental human rights, given the dependence of indigenous minority cultures on a healthy environment, and the strong cultural and spiritual link between indigenous peoples and their traditional lands.

5.8 With respect to article 24 of the Covenant, the principle of intergenerational equity places a duty on current generations to act as responsible stewards of the planet and ensure the rights of future generations to meet their developmental and environmental needs. The remedies requested by the authors are reasonable and proportionate.

State party's further observations on admissibility and the merits

6.1 In its further observations of 5 August 2021, the State party maintains that the authors' allegations (changes to seasonal patterns, erosion of ancestral land, saltwater intrusion, damage to cultural practices, species and homes) represent possible impacts of climate change, but not existing or imminent violations of Covenant rights caused by the State party, either through act or omission. Those impacts only suggest that adverse effects now may, subject to contingencies, worsen in future. The possible impacts of a slow onset process do not confer victim status on the authors.

6.2 The authors acknowledge that there is still a “window of time in which adaptation measures can… [be] planned and implemented.” The authors themselves contemplate the consequences that might arise “if and when the authors' islands become unviable for habitation.”

6.3 Climate change is a global phenomenon attributable to the actions of many States. It requires global action, unlike other environmental issues previously considered by the Committee. The general effects of climate change, and the effectiveness of any mitigation or adaptation measures to address those effects, are not within the complete control of any State.Footnote ²⁴

6.4 The State party's position is not, as the authors allege, that they must simply wait and suffer increasingly severe climate impacts. The international community has sought to address climate change primarily, and rightly, as a matter of international cooperation and under international environmental agreements. Notwithstanding the authors' dissatisfaction with the pace and nature of the State party's efforts, this does not mean that the State party's response to the threat of climate change, and consequently the response of many other States, amount to a violation of the Covenant.

6.5 Applying the principle of systemic integration described by the International Law Commission, relevant rules for the purpose of article 31 (3)(c) of the Vienna Convention on the Law of Treaties must concern the subject matter of the treaty term at issue.Footnote ²⁵ Climate change treaties do not provide evidence of the object and purpose of the Covenant, nor the meaning of its terms.

6.6 Regarding the exhaustion of domestic remedies, States parties to the Covenant are not required to make available a domestic remedy for the purposes of article 2 (3) of the Covenant where: a) the alleged violations are outside the scope of the Covenant (as is the case here, as the allegations relate to Australia's compliance with international climate change treaties); or b) there is no breach of rights recognised by the Covenant as properly understood, as is the case for the allegations in the present communication.

6.7 The obligation to respect under article 2 (1) of the Covenant is a positive obligation of non-interference with Covenant rights that only extends to real risks against which a State party can offer protection.Footnote ²⁶ The alleged threat to the authors' rights is a global phenomenon arising from myriad acts committed by innumerable private and State entities over decades that are unquestionably beyond the jurisdiction and control of the State party. It would be perverse if the Covenant were to impose a duty or obligation on the State party – to ensure that climate change does not impair the authors' rights – that the State party could not hope to fulfil. Moreover, the authors acknowledge the multiplicity of global causes of climate change, and that there is still opportunity for mitigating factors at the national and global level to intervene in order to allay the threat posed by its future impacts.

6.8 Any positive obligation that arises under the Covenant is principally limited to the threat posed by the acts of private persons or entities within a State party's jurisdiction and control. This could also extend to positive obligations in respect of environmental issues that pose a direct, specific and objective threat to enjoyment of Covenant rights, such as use of pesticides (like in Portillo Cáceres v. Paraguay), where it is within the scope of a State's power to avoid that risk. However, it does not create an obligation to protect generally against the future effects of climate change, which, as a matter of international law, extends well beyond the scope of a single State party's jurisdiction and control.

6.9 Academic scholars have noted that “causal pathways involving anthropogenic climate change, and especially its impacts, are intricate and diffuse,” and that human rights law “cannot actually address the depth and breadth of the causes and impacts of climate change.”Footnote ²⁷ A threat that is not attributable to a State cannot be ensured or protected by that State where such protection cannot be achieved by the State alone.

6.10 Positive obligations under the Covenant do not require maximum possible resources nor highest possible ambition. To adopt such an unprecedented test would not only place an impossible burden on States but would also displace reasonable policy choices made in good faith by States as they assess a range of threats and challenges that impact on the enjoyment of human rights under the Covenant and decide how to distribute limited resources to address them.

6.11 It would be both inappropriate and unfounded for the Committee to interpret the Covenant in such a way as to allow it to re-make the informed, good faith and difficult policy decisions of a democratically elected government that inherently involve compromises, trade-offs and the allocation of limited resources across the range of challenges to the full enjoyment of human rights. In urging the Committee to adopt an unduly broad interpretation of a positive obligation, the authors invite the Committee to disregard States' discretion in making relevant decisions, even if exercised in good faith. Fulfilment of positive obligations under the Covenant must recognise competing challenges to limited State resources.

6.12 The authors' claims under article 27 of the Covenant are both factually and legally incorrect. The State party is taking measures to prevent the islands from becoming unviable for habitation, through the adaptation and mitigation measures described at length in its observations. The State party provides detailed information about legislation, policies and practices designed to protect the cultural rights of Torres Strait Islanders. Such measures include the Torres Strait Islander Cultural Heritage Act 2003 (Qld), the Torres Strait Islander Traditional Child Rearing Practice Act 2020 (Qld), the Traditional Ecological Knowledge Project of the TSRA, the declaration of three Indigenous Protected Areas in the Torres Strait region, the use of Torres Strait Infrastructure and Housing Indigenous Land Use Agreements, and the Local Thriving Communities program. As a matter of international law, article 27 of the Covenant does not involve any positive obligation to prevent slow-onset risks that might arise in future. A breach of article 27 of the Covenant only arises at the time of any denial – it does not convert a risk of future denial into a present breach. Even if the Committee were to admit an intergenerational element of cultural transmission, nothing suggests that the State party has directly interfered in or failed to protect the authors' ability to transmit their culture across generations.

6.13 Article 24 (1) of the Covenant does not itself set out the rights of children but refers to necessary measures of protection for children. Instead of identifying any measures specifically sought by the authors to obtain such protection for children, their additional submissions only describe climate change impacts which affect the Torres Strait population generally – adults and children alike. The special measures warranted by article 24 of the Covenant seek to protect children because of their status as minors. The effects of climate change do not depend upon a person's status as a minor.

Issues and proceedings before the Committee

Individual opinion by Committee Member Duncan Laki Muhumuza.

1. The Committee found that there was no violation of Article 6 based on the information provided by the State Party.

2. I have comprehensively perused the information provided by both the authors and the State Party and I am convinced that there is a violation of Article 6 of the Covenant, which states that;

3. “Every human being has the inherent right to life… protected by law, and that no one shall be arbitrarily deprived of his life.”

The Committee found that there was no violation of Article 6 by the State Party based on the information provided by the State Party.

4. The Committee considered the information provided by the State Party in as far as the adaptative measures put in place to reduce the existing vulnerabilities and build resilience to climate change-related harms to the islands and it was on those grounds that the Committee found that there was no violation of Article 6.

5. I am cognisant of the adaptive measures that the State Party has taken under the Torres Strait Seawalls Program (2019–23), where:

1. (a) Multiple infrastructures will be constructed and upgraded to address ongoing coastal erosion and storm surge impacts at Poruma, Warraber, Masig, Boigu and Iama.

2. (b) By 2022, several coastal mitigation works had been completed on Boigu with funding of $15 million, the construction of a 1,022-metre-long wave return wall, the raising and extension of an existing bund wall to 450 metres, and the upgrading of stormwater drainage infrastructure.

3. (c) Coastal mitigation works on Poruma, Warraber and Masig were scheduled to begin in 2021 or 2022 and be completed by 2023.

…

9. These efforts and measures taken/and or yet to be taken are commendable and appreciated. However, there is an appalling outcry from the authors that has not been addressed and hence, the authors' right to life will continue to be violated and their lives endangered.

10. I am of the considered view that the State party has failed to prevent a foreseeable loss of life from the impact of climate change. As highlighted by the Urgenda Foundation v. the State of Netherlands case Footnote ¹, the State Party is tasked with an obligation to prevent a foreseeable loss of life from the impacts of climate change, and to protect the authors' right to life with dignity.

11. In the instant case before us, the State Party has not taken any measures to reduce greenhouse gas emissions and cease the promotion of fossil fuel extraction and use, which continue to affect the authors and other islanders, endangering their livelihood, resulting in the violation their rights under article 6 of the Covenant.

12. The citizens of Torres Strait Islands have also lost their livelihood at the island due to the on-going climate changes and the State Party has not taken any measures to mitigate this factor. As a result of rise in the sea levels, saltwater intruded into the soils of the islands and as such lands previously used for traditional gardening could no longer be cultivated. The coral bleaching that occurred has led to the disappearance of crayfish which is a fundamental source of food and income for the authors.

13. These factors combined point to the imminent danger or threat posed to people's lives which is already affecting their lives, yet the State Party being aware has not taken effective protective measures to enable the people to adapt to the climate change.

14. The Urgenda case defined “Climate change as a real and imminent threat and requires the State to take precautionary measures to prevent infringement of rights “as far as possible.”

15. The Court further held that it is appropriate to speak of a real threat of dangerous climate change, resulting in the serious risk that the current generation of citizens will be confronted with loss of life/or a disruption of family life.

16. The authors have ably informed the Committee that the current state of affairs and existence in the Torres Strait Islands is under imminent threat due to the on-going climate change and therefore, the State Party should take immediate adaptive precautionary measures to thwart the climate changes, and preserve the lives of the islanders including their health and livelihood. Any further delays or non-action by the State Party will continue to risk the lives of the citizens which is a blatant violation of Article 6 (1) of the Covenant.

17. Accordingly, I find that there is a violation of Article 6 and as a Committee, we should implore the State Party to take immediate measures to protect and preserve the lives of the people at Torres Strait Islands. In order to uphold the right to life, States must take effective measures (which cannot be undertaken individually) to mitigate and adapt to climate change and prevent foreseeable loss of life.

Individual opinion by Committee Member Gentian Zyberi (concurring)

1. I am generally agreed with the Committee's findings.Footnote ¹ In this individual opinion, I explain my position on adaptation and mitigation measures, the law on international responsibility for countering climate change effects and adequate measures, and the violation of Article 27.

2. After having acknowledged climate change as a common concern of humankind in its preamble, the 2015 Paris Agreement addresses mitigation and adaptation respectively under Articles 4 and 7. Mitigation efforts are aimed at addressing the causes of climate change by preventing or reducing the emission of greenhouse gases (GHG) into the atmosphere. Adaptation efforts are aimed towards adjusting to the current and future effects of climate change. Both types of measures are intrinsically connected and require action by States (and non-State actors), individually and jointly through international cooperation.

3. The State party in this case has taken both mitigation and adaptation measures. When it comes to mitigation measures, assessing the nationally determined contributions taken by States parties to the ICCPR under the 2015 Paris Agreement, when the State is party to both treaties, is an important starting point. States are under a positive obligation to take all appropriate measures to ensure the protection of human rights. In this context, the due diligence standard requires States to set their national climate mitigation targets at the level of their highest possible ambition and to pursue effective domestic mitigation measures with the aim of achieving those targets.Footnote ² When a State is found to not have fulfilled these commitments, such a finding should constitute grounds for satisfaction for the complainant/s, while the State concerned should be required to step up its efforts and prevent similar violations in the future. The requirement of due diligence applies also to adaptation measures.

4. It has been 30 years since States have recognized climate change as a cause of common concern and action in the 1992 Earth Summit, but despite important developments in the form of the 1992 United Nations Framework Convention on Climate Change (UNFCC), the 1997 Kyoto Protocol, and the 2015 Paris Agreement, individual and joint State efforts at addressing the climate crisis remain insufficient.Footnote ³ Over the years, the law on international responsibility on climate change has developed progressively.Footnote ⁴

5. A clear limitation of the law on international responsibility in cases of climate change and related litigation, is the difficulty involved in addressing what constitutes shared responsibility.Footnote ⁵ Since it is the atmospheric accumulation of CO2 and other GHGs that, over time, gives rise to global warming and climate change,Footnote ⁶ States should act with due diligence when taking mitigation and adaptation action, based on the best science. This is an individual responsibility of the State, relative to the risk at stake and its capacity to address it. A higher standard of due diligence applies in respect of those States with significant total emissions or very high per capita emissions (whether these are past or current emissions), given the greater burden that their emissions place on the global climate system, as well as to States with higher capacities to take high ambitious mitigation action.Footnote ⁷ This higher standard applies to the State party in this case.

6. The Committee has significant practice on Article 27, with much of its case law concerning the rights of indigenous peoples.Footnote ⁸ In this case, it has found a violation because of the State party's failure to adopt timely adequate adaptation measures to protect the authors' right to enjoy their minority culture under article 27 of the Covenant. In my view, the Committee should have linked the State obligation to “protect the authors' collective ability to maintain their traditional way of life, to transmit to their children and future generations their culture and traditions and use of land and sea resources”Footnote ⁹ more clearly to mitigation measures, based on national commitments and international cooperation – as it is mitigation actions which are aimed at addressing the root cause of the problem and not just remedy the effects. If no effective mitigation actions are undertaken in a timely manner, adaptation will eventually become impossible. Such land and sea resources will not be available for indigenous peoples or even for humanity more generally, without diligent national efforts, as well as joint and concerted mitigation actions of the organized international community.

7. Climate change concerns have been addressed over the years by the Committee and other UN human rights treaty bodies,Footnote ¹⁰ the UN Special Procedures,Footnote ¹¹ and more generally by the UNFootnote ¹². This case shows the possibilities and limitations of human rights-based litigation. That said, alongside other general or specific institutional arrangements addressing climate change issues, the Committee provides a suitable venue for addressing some concerns, especially under articles 6, 7, 17 and 27, both under the Optional Protocol, as well as under Article 41 of the Covenant.

Joint opinion by Committee Members Arif Bulkan, Marcia V. J. Kran and Vasilka Sancin (partially dissenting).

1. In addition to a violation of articles 17 and 27 found by the majority of the Committee, we would also find a violation of the right to life under article 6 of the Covenant.

2. The majority opinion correctly states that article 6 should not be interpreted restrictively.Footnote ¹ Yet, the “real and foreseeable risk” standard employed by the majority interprets article 6 restrictively, and was borrowed from the dissimilar context of refugee cases.Footnote ² In Teitiota the Committee concluded that due to insufficient information from the author, climate change was not a real or foreseeable enough risk to require the State party grant him refugee status. In contrast, here the primary question is whether the alleged violations of article 6 themselves ensue from inadequate mitigation and/or adaptation measures on climate change by the State party. Using a more accurate standard, from a factually similar case relating to environmental damage by pesticides, the question becomes whether there is “a reasonably foreseeable threat” to the authors' right to life.Footnote ³ The authors detail flood related damage, water temperature increases, loss of food sources, and most importantly, explain that the islands they live on will become uninhabitable in a mere 10–15 years according to the Torres Strait Regional Authority (TSRA), a governmental body. Together, this evidence provides “a reasonably foreseeable threat” constituting a violation of article 6.

3. Using the “real and foreseeable risk” standard, the majority opinion requires adverse health impacts to demonstrate an article 6 violation. Not finding such impacts, the majority fails to find a violation of article 6. Nonetheless, the authors detail “real and foreseeable risks” to their lives resulting from the flooding of the Torres Strait islands. First, the authors provide evidence of significant loss of food sources on which they rely to sustain themselves and their families. The crops lost include sweet potato, coconuts, and banana, which are required food sources and livelihood for the authors. The authors demonstrate that flooding has caused land erosion making food production impossible. They also detail that warmer waters due to climate change reduced the availability of cray fish, another primary food source. Second, the authors detail repeated damage to their homes, including significant water damage to the foundation of one author's home. Thus the authors have demonstrated “real and foreseeable risks” to their lives through significant loss of food sources, livelihood, and shelter.

3. Interpreting article 6 restrictively, the majority opinion observes that the authors conflate violations of the article 27 guarantee of minority rights to enjoy culture with violations under the article 6 guarantee of the right to life.Footnote ⁴ Accordingly, the majority finds a violation of article 27 but not of article 6. While the authors do discuss these violations as related, citing similar facts, the Committee's jurisprudence does not require that facts relating to different violations arise from different sets of facts. The risks to the authors' right to life are independent and qualitatively different from the risks to their right to enjoy their culture. Consequently, we are unable to agree that a violation of article 27 sufficiently addresses the authors' claims.

4. We endorse the view that integral to article 6 is the right to live with dignity.Footnote ⁵ It is, however, critical to do more than simply reference the Committee's jurisprudence, it must also be used progressively, based on current realities. This jurisprudence unequivocally notes that no derogation is permitted from article 6.Footnote ⁶ Moreover, it clarifies the direct connection between environmental harms, the right to life, and the right to live with dignity;Footnote ⁷ and that State parties must duly consider the precautionary approach on climate change.Footnote ⁸ Given the urgency and permanence of climate change, the need to adhere to the precautionary approach is imperative. In addition, the singular focus on the future obscures consideration of the harms being experienced by the authors, which negatively impact on their right to a life with dignity in the present. The unfortunate outcome is that the Committee's jurisprudence promises far more than the majority delivers.

5. While we agree that the State party is not solely responsible for climate change, the main question before the Committee is significantly narrower: has the State party violated the Covenant by failing to implement adaptation and/or mitigation measures to combat adverse climate change impacts within its territory resulting in harms to the authors? The majority opinion relies on projects initiated by the State party since 2019, which might be completed by 2023.Footnote ⁹ While these measures help build climate change resilience, the majority does not sufficiently consider the violations of article 6 that had already occurred at the time of filing this communication. Indeed, promises of future projects are insufficient remedies as they have not yet occurred whereas damage to the foundation of the authors' homes has already occurred. Soil where the authors grow food for subsistence has already been eroded, and crops lost. These violations are a direct result of flooding which could have been prevented by adaptation measures including the timely construction of a seawall to protect the islands where the authors live. Indeed, in its 2014 report, the TSRA concluded that Australia had yet to take any steps on 33 out of the 34 adaptation measures suggested.

6. The State party has a positive obligation to minimize “reasonably foreseeable threats to life”Footnote ¹⁰ and should remedy these violations by implementing adaptation measures including those identified by the TSRA in 2019. Despite multiple requests and knowledge of the ongoing impacts on the lives of the authors, the State party did not undertake adaptation measures in a timely manner. Consequently, we would find that the State party violated the authors' right to life under article 6 of the Covenant in addition to the violations found by the majority.

Opinión indivudal del miembro del Comité Carlos Gómez Martínez

1. El calentamiento global coloca en situación de grave riesgo la vida familiar de los demandantes (artículo 17 del Pacto) y también la supervivencia de las comunidades indígenas a las que pertenecen (artículo 27 del Pacto) dada la circunstancia de que habitan islas de muy escasa altitud en el estrecho de Torres, fácilmente inundables por la subida del nivel del mar, lo cual evidencia su extrema vulnerabilidad y les otorga la condición de víctimas potenciales de violación de los derechos humanos que antes se han mencionado y de los que son titulares.

2. Sin embargo, la evitación total del riesgo y de los daños derivados del cambio climático está fuera del alcance de la actuación aislada del Estado parte dado que el calentamiento de la tierra es un fenómeno global al que solo se puede dar respuesta mundial en una lucha en la que han de implicarse todos o, al menos, una parte significativa de los Estados del planeta. Por ello no puede concluirse que el Estado parte haya violado los derechos de los demandantes por no haber evitado los riesgos o no haber eliminado totalmente los daños que puedan sufrir, derivados del cambio climático.

3. Por esta razón, el Comité se centra en las medidas de adaptación al cambio climático. El dictamen admite, en sus párrafos 8.9 y 8.11, que el Estado parte ha llevado a cabo acciones concretas para la adaptación de la vida de los demandantes al nuevo entorno que traerá consigo el cambio climático, siendo de especial relevancia la construcción de muros de contención de las aguas del mar, obras ya iniciadas y cuya finalización se espera para 2023.

4. Cuestión distinta es si las medidas de adaptación son o no las exigibles hasta el punto de que, por no ser suficientes, puedan suponer la violación de los derechos humanos de los demandantes. La adaptación al cambio climático es un concepto indeterminado que puede ir desde una leve acomodación hasta la drástica configuración de un nuevo entorno plenamente resiliente que permita la vida en plenitud de los demandantes en las nuevas circunstancias climáticas. En cualquier caso, corresponde al Estado parte decidir el curso de acción que debe emprender para adaptar su país al cambio climático atendiendo a los intereses de toda la ciudanía y a la posible opción por distintas políticas, tanto ambientales, como pueden ser la reforestación con especies resistentes o la facilitación de la transición energética, como de otra índole, como puede ser la reducción de la pobreza, que también tiene importante repercusión en el disfrute de los derechos humanos.

5. El propio dictamen señala en el párrafo 8.9 in fine que “el Comité no está en condiciones de concluir que las medidas de adaptación adoptadas por el Estado parte sean insuficientes para representar una amenaza directa al derecho de los autores a una vida digna”, por lo que excluye la violación del artículo 6 del Pacto. Si ello es así, no se entiende como el Comité sí se considera a sí mismo en condiciones de concluir que las medidas de adaptación emprendidas por el Estado parte sean insuficientes a los efectos de apreciar una violación de los artículos 17 y 27 del Pacto. No se explica por qué el juicio de suficiencia no es válido a unos efectos (no violación del artículo 6) y sí lo es a otros (violación de los artículos 17 y 27).

6.  En definitiva, el dictamen no explica la razón por la cual el Comité considera que las medidas de adaptación llevadas a cabo por el Estado parte (la construcción de diques de contención del agua del mar), o el retraso en ejecutarlas (iniciadas en 2017 y 2018 en los malecones de Boigu y Poruma, párrafo 2.7), han sido insuficientes hasta el punto de constituir una violación de los artículos 17 y 27 del Pacto Internacional de Derechos Civiles y Políticos y tampoco explica qué otra actuación suplementaria le hubiera sido exigible al Estado parte para poder concluir que no se había producido dicha violación.

Opinión individual del miembro del Comité Hernán Quezada (parcialmente disidente)

1. Respecto de la Comunicación 3624/2019 (Daniel Billy y otros vs Australia), comparto la decisión del Comité en el sentido de que los hechos examinados ponen de manifiesto una violación de los derechos de los autores en virtud de los artículos 17 y 27 del Pacto, al no cumplir el Estado Parte con su obligación de aplicar medidas adecuadas para proteger el hogar, la vida privada y la familia de los autores, y para proteger el derecho de los autores a disfrutar de su cultura minoritaria, respectivamente.

2. Sin embargo, en lo relativo al derecho a la vida, lamento no poder unirme a la mayoría del Comité, la cual concluyó que la información disponible no revela una violación por el Estado Parte de los derechos de los autores en virtud del artículo 6 del Pacto.

3. El propio Comité entiende (párr. 8.3) que el derecho a la vida no debe interpretarse en forma restrictiva y que su protección requiere de la adopción de medidas positivasFootnote ¹. En este sentido el Comité ha establecido en su Observación General N°36 que las amenazas al derecho a la vida pueden incluir “los efectos adversos del cambio climático”, lo que obliga a los Estados Partes a “adoptar todas las medidas apropiadas para hacer frente a las condiciones generales de la sociedad que puedan dar lugar a amenazas directas al derecho a la vida o impedir que las personas disfruten de su derecho a la vida con dignidad”Footnote ². Al respecto, debe tenerse presente que el Estado Parte durante las últimas décadas es y ha sido uno de los países que han producido grandes cantidades de emisiones de gases de efecto invernadero (párr. 7.8).

4. Según los hechos denunciados y no rebatidos por el Estado Parte, los autores han experimentado y experimentan una serie de problemas derivados de los efectos del cambio climático que afectan sus vidas y la existencia misma de las islas que habitan: la inundación de aldeas y de tierras funerarias ancestrales; la pérdida por erosión de sus tierras tradicionales, incluidas las plantaciones y los jardines; la destrucción o marchitamiento de los jardines tradicionales por la salinización causada por las inundaciones o la entrada de agua de mar; la disminución de especies marinas de importancia nutricional y cultural; la decoloración de los corales, y la acidificación de los océanos, entre otros. A todo ello se suma el riesgo de inhabitabilidad de sus islas debido al persistente aumento del nivel del mar.

5. Si bien el Estado Parte ha adoptado en los últimos años diversas medidas para hacer frente a los efectos adversos del cambio climático y las emisiones de carbono generadas en su teritorio, esto es aún insuficiente para garantizar a los autores el disfrute de una vida digna en las islas que habitan en el Estrecho de Torres. En efecto, el Comité ha constatado (párr. 8.12) que el Estado Parte no ha respondido varias alegaciones de los autores en este sentido, en particular la no construcción de medidas de adaptación para mejorar los malecones y el retraso en la construcción de diques, y tampoco ha dado explicaciones alternativas sobre la reducción de los recursos marinos necesarios para la alimentación y la pérdida de cultivos y árboles frutales. Aun cuando dichas constataciones del Comité están relacionadas con la violación del Artículo 17 del Pacto, la falta o la insuficiencia de medidas de adaptación para enfrentar las consecuencias adversas del cambio climático ha repercutido negativamente en las condiciones de vida de los autores. Por lo demás, las amenazas que se ciernen sobre sus medios de subsistencia y sobre la existencia misma de las islas, han creado una situación de incertidumbre y, por lo mismo, afectan su salud mental y su bienestar, impidiendo el derecho a disfrutar de una vida dignaFootnote ³. En este contexto, los autores y sus familias ya han sufrido y aún sufren una violación al derecho a la vida, en el sentido de “vida digna”, lo que es una realidad concreta que requiere reparación, independientemente de las futuras mejoras que puedan lograrse con las medidas de mitigación y adaptación que el Estado Parte ha comenzado a implementar en los últimos años o que estarían por iniciarse, según la información obtenida por el Comité (párr. 8.7).

6. Con respecto a la oportunidad en la adopción de medidas, cabe tener presente que la comunicación de los autores (presentación inicial) es de fecha 13 de mayo de 2019, cuando los efectos adversos del cambio climático en las islas del Estrecho de Torres ya habían producido, durante largo tiempo, serios impactos negativos en sus vidas. Sin embargo, la mayor parte de las obras de mitigación costera emprendidas por el Estado Parte, según lo constatado por el Comité, estaban programadas para comenzar recién en 2021 o 2022 y estar terminadas en 2023 (islas Poruma, Warraber y Masig). Solamente en la costa de una de las islas (Boigu) se habían completado en 2022 varias obras de mitigación.
