Abstract

Greenwashing cases holding businesses to account for false or misleading eco-claims are an increasingly visible component of the business and human rights landscape globally. In the European Union (EU), the Unfair Commercial Practices Directive is the centrepiece of regulation for business-to-consumer claims. Within the European Green Deal initiative, the EU is revising this framework, first with the Directive to ‘Empower Consumers for the Green Transition,’ and second the pending proposal for a ‘Green Claims Directive,’ introducing detailed requirements on the substantiation and communication of ‘green claims’ to consumers. If fully adopted, this fundamental reform will impose greater restraints on the discretion of any authority charged with the assessment of green claims and provide more uniform criteria across the EU, resulting in more accurate environmental claims and greater clarity for consumers and businesses alike.

I. Introduction

Greenwashing needs no introduction these days: Companies that make unsubstantiated or misleading claims about the environmental advantages of their products, services or practices risk being named and shamed by the media and also face the prospect of legal proceedings. Greenwashing cases are rapidly evolving in Europe, as well as globally.Footnote 1 European Union (EU) law tackling greenwashing has mainly been the Unfair Commercial Practices Directive (UCPD), which has provided a relatively light-touch regulatory framework for consumer law over the last two decades throughout the European Economic Area (EEA).Footnote 2 Advertising or marketing claims including greenwashing could be brought before national courts for highly fact-specific rulings or could be the subject of regulatory investigations, based on rather vague, open-ended criteria.

As part of its Green Deal,Footnote 3 the EU embarked on a fundamental reform of the law on greenwashing, and the UCPD has now been revised by the ‘Directive to Empower Consumers for the Green Transition’ (Directive).Footnote 4 This is only the first of a far-reaching two-step reform process, the second element being the arguably more significant pending separate proposal for a ‘Green Claims Directive’ issued in March 2023, which remains in the EU’s complex legislative adoption process. The proposed Green Claims Directive introduces very specific requirements on the substantiation and communication of ‘green claims’ to consumers. This reform, once fully in force, will result in a major departure from the current situation which accords a broad margin of discretion to national courts (and authorities) in determining what is misleading or unfair in an environmental claim. The aim is to provide consumers in Europe with the ability to drive the green transition by making environmentally conscious choices in their purchasing decisions, based on uniform criteria.

The proposed Green Claims Directive and UCPD sit within a broader set of initiatives that form part of the European Green Deal and that are intended to improve how businesses interact with the environment and human rights. Various aspects of the Green Deal have recently come under scrutiny as being potentially too burdensome for businesses, particularly with respect to reporting obligations and supply chain due diligence relating to the environment and human rights, but so far, the proposal for a Green Claims Directive has been maintained by the European Commission and is proceeding through the legislative process.

II. Snapshot of the Current EU Framework on Greenwashing Claims

The EU’s current rules on misleading consumer claims are based on a blacklist of practices that are misleading under any circumstances,Footnote 5 and a general prohibition of claims which are ‘likely to deceive the average consumer (…) likely to cause him to take a transactional decision that he would not have taken otherwise’ or ‘omits material information that the average consumer needs, according to the context, to take an informed transactional decision.’ The way these latter provisions have been applied by national courts is highly fact-specific, depending on a court’s view on what would have an impact on an average consumer’s decision, and as a result, very variable.Footnote 6

For example, in the ‘Froggy’ case, the Brussels Court of Appeal considered whether statements on plastic used in soap bottles, which were presented as containing recycled material recovered from the oceans, were misleading to the average consumer. While certain representations relating to recycled content were factually incorrect, the Court concluded (among other points) that there was insufficient evidence to support the conclusion that this would have altered a consumer’s transactional decision.Footnote 7 In addition to the courts in EU Member States, the Court of Justice of the European Union has also developed a body of case law based on preliminary references from national judges, with the aim of further clarifying certain concepts such as that of an ‘average consumer.’Footnote 8

Although the UCPD is key, greenwashing claims in the EU may be subject to other regulatory frameworks and non-judicial bodies, e.g. self-regulatory bodies in the advertisement industry have codes of conduct regarding misleading content, and decisions by the Dutch Advertising Code Commission (ACC)Footnote 9 and the UK Advertising Standards Authority (ASA) offer an interesting non-judicial perspective. National consumer protection authorities and competition authorities are competent to deal with greenwashing, and OECD National Contact Points (NCP) can receive complaints and issue decisions on environmental and climate change claims.Footnote 10 Other elements of the European Green Deal are also intended to combat greenwashing, e.g. the EU Green Bond Regulation,Footnote 11 TaxonomyFootnote 12 and the Corporate Sustainability Reporting Directive.Footnote 13 These laws are aimed at increasing transparency by enabling access to reliable sustainability information regarding the financial services industry (the EU Green Bond Regulation and the Taxonomy) and a company’s overall performance relating to the environment and human rights (the EU Corporate Sustainability Reporting Directive).

III. The Upcoming Reform of EU Greenwashing Laws

The EU is in the process of dramatically reforming its regulatory framework relevant to consumer protection in relation to greenwashing. The aim is to achieve more clearly spelled-out rules, leaving less freedom for regulators and judges and resulting in less divergence in decision-making, greater predictability for business and better protection for consumers who should be able to make more sustainable purchasing choices Europe-wide.

A. Directive Empowering Consumers for the Green Transition

The newly adopted directive amends the UCPD and the EU Consumer Rights Directive (Directive 2011/83). Formal implementation is still some time away, and it will now need to be transposed in the national laws of each EEA country. The Directive sets a final applicability date for September 27, 2026.Footnote 14 However, companies would be well advised to get ready now to make the changes which will be required.

The effect will be that EU authorities can crack down much more heavily on greenwashing. In fact, the UCPD already permits many greenwashing claims to be deemed misleading on a case-by-case basis; the new changes add to the list of clearly blacklisted practices and focus on increasing legal certainty and significantly raising the bar on what is acceptable in terms of green claims.Footnote 15 The Directive also adds valuable provisions relating to sustainability labels, rights of repair and durability.

The Directive applies to written and oral environmental claims and pictorial, graphic and symbolic representations. Three new greenwashing-related claims are banned outright:Footnote 16

  • • ‘Making a generic environmental claim for which the trader is not able to demonstrate recognized excellent environmental performance relevant to the claim.’

This includes claims which are not specified in clear and prominent terms in the same mediaFootnote 17 such as ‘environmentally friendly,’ ‘eco-friendly,’ ‘green,’ ‘nature’s friend,’ ‘ecological,’ ‘environmentally correct,’ ‘climate friendly,’ ‘gentle on the environment,’ ‘carbon friendly,’ ‘energy efficient,’ ‘biodegradable’ and ‘biobased.’Footnote 18 ‘Excellent environmental performance’ may be demonstrated for example by compliance with EU Ecolabel Regulation 66/2010, or national or regional ISO 14024 Type I ecolabelling schemes.Footnote 19

  • • ‘Making an environmental claim about the entire product or the trader’s entire business when it concerns only a certain aspect of the product or a specific activity of the trader’s business.’

This prevents companies from relying on the presentation of a small, though undeniably environmentally friendly, part of their activities in order to characterize themselves as overall ‘green.’ Such claims by banks and oil companies have been considered unacceptable in the UK.Footnote 20

  • • ‘Claiming, based on the offsetting of greenhouse gas emissions, that a product has a neutral, reduced or positive impact on the environment in terms of greenhouse gas emissions.’

This prohibition is likely to have a profound impact and has given rise to much attention. Offsetting refers to investments in projects that compensate, or ‘offset,’ greenhouse gas emissions, such as the planting of forests. The controversial aspects of offsetting practices have been highlighted in several recent greenwashing cases, the best known being perhaps the case against the airline KLM in The Netherlands.Footnote 21 This amendment will ban ‘climate neutral’Footnote 22 claims in relation to a product made to consumers if based on offsetting. One important nuance is noted in the (non-binding) recitals to the Directive, suggesting that there should still be some leeway to inform consumers about offsetting projects, although no longer in an unqualified manner suggesting that a product or service is carbon neutral.Footnote 23

In addition to these new bans, other significant amendments are made to UCPD Article 6. Notably, a misleading claim will include ‘making an environmental claim related to future environmental performance without clear, objective, publicly available and verifiable commitments set out in a detailed and realistic implementation plan that includes measurable and time-bound targets and other relevant elements necessary to support its implementation, such as allocation of resources, and that is regularly verified by an independent third party expert, whose findings are made available to consumers.’ This targets, for example, vague slogans by companies relating to their net zero trajectories. The UCPD will now require more substantiation and objective third-party verification. In that sense, the reform is a clear precursor to the changes anticipated in the proposed Green Claims Directive.

B. Proposal for a Green Claims Directive

In March 2023, the European Commission proposed a Directive on the substantiation and communication of explicit environmental claims (Green Claims Directive),Footnote 24 which is easily the most ambitious greenwashing law reform to date in Europe (and probably globally).Footnote 25 It is still in the process of adoption and amendments are likely. This measure is targeted exclusively at ‘green claims,’ defined by reference to the reformed UCPD as explicitFootnote 26 environmentalFootnote 27 claims made by traders about products or traders in business-to-consumer commercial practices. Any voluntary, explicit environmental claim would be subject to detailed new requirements affecting how claims are substantiated and communicated. A certificate of conformity for green claims, drawn up by an independent verifier, would be required.Footnote 28 Consumers would be able to access this certificate of conformity, for example by a website link or QR code,Footnote 29 to quickly verify the veracity of the claim made. Companies will also have to track new scientific developments and take account of these. The role of independent verifiers as a sort of first line of assessment and quality assurance is particularly striking.Footnote 30

The proposed Green Claims Directive opens up new routes for complaints against traders and for representative actions to be brought in court and provides for substantial penalties to be imposed, including maximum fines of not less than 4 per cent of turnover in a Member State or the Member States concerned. The proposal also has far-reaching provisions aimed at preventing the proliferation of new labelling systems throughout the EU.

Under the European Commission’s 2024-2029 priorities, there is an increased focus on the competitiveness of businesses within the EU.Footnote 31 As part of this focus, the European Commission is exploring the simplification of various rules adopted under the European Green Deal through so-called ‘Omnibus’ packages. However, at this stage, the proposal for a Green Claims Directive is maintained in the Commission’s Work Programme, and the adoption process by the Council and Parliament has begun.Footnote 32 The shape of its final adoption, however, remains uncertain.

IV. Conclusion: A More Structured Analysis, but No One Size Fits All

The result of these reforms will be substantially greater restraints on the discretion of any authority charged with the assessment of green claims, be that a national consumer authority or a judge, in contrast with the current freedom to determine appropriate standards based on the view of the ‘average consumer.’ The basic principles of the EU framework will not change, but an extra layer of clarity of specification and unambiguous requirements will be added to the open-ended framework of unacceptable green claims. While there is greater clarity in terms of the ‘blacklisted’ practices which will definitely be considered misleading and how other claims should be considered, the proposed Green Claims Directive explicitly confirms that the required certificate of conformity from an independent verifier would not prejudge the assessment of a national court as to whether a claim is misleading.Footnote 33

The provisions on independent verification in these reforms reflect a general trend seen in other parts of the ‘Green Deal’ package and EU legislation adopted under the first Von der Leyen Commission. Provisions relating to third-party verification are included in the recently adopted EU Deforestation Regulation,Footnote 34 the Carbon Border Adjustment Mechanism RegulationFootnote 35 and the Corporate Sustainability Reporting DirectiveFootnote 36 as well as the recently adopted Corporate Sustainability Due Diligence Directive.Footnote 37 The EU approach to corporate sustainability and the Green Deal is however under review, on the basis that EU business needs greater simplification to foster competitiveness. The scope of review and the measures covered are currently unclear, but verification procedures generally, as well as those included in the Green Claims Directive, may well be subject to simplification. The value of independent verification depends on the rigour and reliability of third-party audits, and there is increasing recognition of the challenge that the nascent environmental audit industry is properly regulated to ensure good practices are developed and maintained.

To conclude, the newly reformed UCPD aims to better protect consumers by explicitly spelling out greenwashing claims that will be prohibited EU-wide, and tightening up the criteria for making green claims generally. However, it does not fundamentally change the framework of assessment. Even with the additional impact of the potential adoption of the proposed Green Claims Directive, the individual assessments of national courts and regulators will continue to play a crucial role in determining what types of green claims are misleading or unfair; but crucially, these assessments should become more structured and focused on verifying if the new requirements set out in the reformed EU framework have been followed. More justifiable green claims and greater clarity for consumers and businesses should result.

19 In essence, in order to make a generic environmental claim, environmental performance must be demonstrated by reference to another type of classification outside the UCPD framework itself. See, e.g. ibid at 11 (‘“[R]ecognised excellent environmental performance” means environmental performance compliant with Regulation (EC) No 66/2010 of the European Parliament and of the Council or with national or regional EN ISO 14024 Type I ecolabelling schemes officially recognized in the Member States, or top environmental performance in accordance with other applicable Union law’).

20 Although not interpreting the UCPD, practice of the UK ASA provides some useful context here. In a ruling of 19 October 2022 regarding the bank HSBC UK, the ASA noted that while HSBC’s green claims in that particular instance, e.g. relating to the planting of trees, were fully accurate, the general claim was still misleading given that HSBC’s overall business remains for a large part focused on fossil fuel investment.

Similar reasoning was applied to Equinor in a ruling of 20 December 2023, where advertisements relating to achieving ‘a smooth energy transition’ where deemed misleading because Equinor’s overall business activities remain largely based on fossil fuels. Equinor, Advertising Standards Authority (20 December 2023), https://www.asa.org.uk/rulings/equinor-asa-a23-1204534-equinor-asa.html (accessed 21 June 2024).

21 In that case, KLM was accused of misleading conduct by using the slogan ‘fly responsibly,’ and ‘CO2ZERO,’ linked to its offsetting of greenhouse gas emissions. See KLM, above note 1.

22 Recital 12 mentions other examples such as ‘CO2 neutral certified,’ ‘carbon positive,’ ‘climate net zero,’ ‘climate compensated,’ ‘reduced climate impact’ and ‘limited CO2 footprint.’ Council Directive (EU) 2024/825, 2024 O.J. (L) 1, 4.
