What the Green Claims Directive Requires
The EU Green Claims Directive, proposed by the European Commission in March 2023, establishes a framework for substantiating and communicating environmental claims. Its core requirements are transformative for how companies market products in the EU.
First, all environmental claims must be substantiated by scientific evidence before they are made. Companies must conduct assessments based on recognised methodologies, including lifecycle assessment where relevant. Claims must identify whether they apply to the entire product, part of the product, or a specific aspect of production. This requirement effectively ends the era of unsubstantiated marketing language.
Second, generic claims such as 'eco-friendly,' 'green,' 'nature's friend,' 'ecological,' 'environmentally correct,' 'climate friendly,' or similar broad terms are banned unless the company can demonstrate excellent environmental performance against recognised benchmarks. Simply claiming a product is 'sustainable' without specifying how and providing evidence is no longer permitted.
Third, claims based on carbon offsetting must clearly state that the claim relates to offset credits, not actual emission reductions. Companies cannot claim a product is 'carbon neutral' or has 'reduced climate impact' based solely on purchased offsets without distinguishing between the product's actual emissions and the offsets. This addresses one of the most common forms of corporate greenwashing.
Fourth, environmental labelling schemes must meet minimum criteria: they must be established through transparent governance with input from relevant stakeholders, have publicly available standards, provide evidence of environmental impact assessment, and involve independent third-party verification. Company-created labels that look like independent certifications will be prohibited.
Fifth, companies must make the substantiation of their environmental claims accessible to consumers, typically through a web link, QR code, or equivalent on the product or at the point of sale. This transparency requirement ensures that consumers can verify claims rather than simply trusting marketing language.
Which Companies and Claims Are Affected
The directive applies to all business-to-consumer environmental claims made in the EU market, with some exemptions. Micro-enterprises (fewer than 10 employees and turnover under 2 million euros) are exempt from the substantiation requirements, though they must still comply with existing consumer protection law prohibiting misleading claims.
The scope covers explicit environmental claims made in commercial communications, on product packaging, or online — including social media marketing. This means the directive affects not only EU-based companies but any company selling products or services to EU consumers, making it a de facto global standard for companies with EU market presence.
Specific claim types that will require substantiation include: claims about a product's carbon footprint or climate impact; claims about recyclability, recycled content, or biodegradability; claims about water use, biodiversity impact, or pollution reduction; claims about durability, repairability, or circular economy attributes; and comparative claims (such as 'greener than competitor X').
The directive works alongside the EU's broader sustainability regulation framework, including the Empowering Consumers for the Green Transition Directive (which amends the Unfair Commercial Practices Directive to specifically address greenwashing), the Corporate Sustainability Reporting Directive (CSRD), and the EU Taxonomy for sustainable activities. Together, these create a comprehensive regulatory framework that makes greenwashing legally risky and financially costly.
Industry sectors most affected include fashion and textiles (where sustainability claims are ubiquitous but often unsubstantiated), food and beverages (where 'natural,' 'organic,' and 'sustainable sourcing' claims are common), personal care and cosmetics (where 'green' and 'natural' marketing is widespread), and cleaning products (where environmental claims are a key differentiator).
Timeline and Enforcement
The Green Claims Directive is part of the European Green Deal legislative programme. The European Commission published its proposal in March 2023. The European Parliament and Council are negotiating the final text through the ordinary legislative process. Once adopted, member states will have 24 months to transpose the directive into national law, with enforcement beginning thereafter.
Based on the legislative timeline, companies can expect the substantiation requirements to become enforceable in the 2026-2027 timeframe, though the exact date depends on how quickly the legislative process concludes. Companies should be preparing now, as the transition requires significant investment in evidence gathering, methodology development, and marketing material revision.
Enforcement will be handled by national consumer protection authorities in each EU member state. Penalties must be 'effective, proportionate, and dissuasive' and may include fines, corrective advertising requirements, product withdrawal, and exclusion from public procurement. The directive also empowers consumer organisations and competitors to bring legal challenges against non-compliant claims.
Some member states are not waiting for the EU-wide directive. France has already enacted legislation (the Climate and Resilience Law) that restricts carbon neutral claims and requires specific conditions for environmental marketing. The Netherlands' consumer authority (ACM) has published sustainability claims guidelines and taken enforcement action against companies. Italy, Denmark, and Spain have also introduced or strengthened national rules on environmental marketing.
For companies outside the EU, the directive's impact extends globally. Any company making environmental claims to EU consumers — whether through direct sales, online marketplaces, or distribution partners — will need to comply. This is similar to how the EU's General Data Protection Regulation (GDPR) established a de facto global standard for data privacy. Companies with international operations are likely to adopt the directive's standards across all markets rather than maintaining different marketing approaches for different regions.
How to Prepare: Action Steps for Businesses
Companies should begin preparing for the Green Claims Directive now, regardless of the exact implementation date. The preparation process involves several steps.
First, audit all current environmental claims across marketing materials, packaging, websites, social media, and sales communications. Identify every claim that could be considered an environmental assertion — including indirect claims made through imagery, brand names, or colour choices (extensive use of green colouring can constitute an implicit environmental claim under the directive).
Second, assess the evidence available for each claim. For each environmental assertion, determine whether you have or can obtain scientific evidence to substantiate it. This may involve commissioning lifecycle assessments, gathering supply chain data, or engaging third-party auditors. Claims that cannot be substantiated should be modified or removed.
Third, review all environmental labels and logos used on products. If you use a self-created environmental label, it will likely need to be either replaced with a recognised independent certification or removed entirely. If you use third-party certifications, verify they meet the directive's criteria for labelling schemes.
Fourth, develop a substantiation infrastructure. Create systems for maintaining and updating the scientific evidence behind your claims. This includes data management processes, regular review cycles, and clear internal responsibilities for environmental claim accuracy.
Fifth, train marketing and communications teams. Ensure that everyone involved in creating or approving marketing content understands what types of claims are permissible, what evidence is required, and what language should be avoided. The directive's requirements represent a fundamental shift from creative marketing to evidence-based communication.
Finally, consider the opportunity. Companies that already invest in genuine sustainability and transparent communication are well-positioned to benefit from the directive, which will eliminate competition from companies that rely on misleading claims. The directive creates a level playing field where genuine environmental performance is rewarded rather than obscured by greenwashing.
