When does the EU Green Claims Directive take effect?

Member states had until March 2026 to transpose the directive into national law. Enforcement began in early-adopting member states in 2026. SMEs (small and medium enterprises) benefit from an additional 18-month delay, with enforcement starting around 2028.

Does the Green Claims Directive apply to B2B marketing?

The directive primarily targets business-to-consumer (B2C) communications. B2B claims in commercial transactions, including tender documentation and supplier contracts, are also covered when those claims will ultimately reach consumers.

What fines can companies face under the Green Claims Directive?

Member states must set maximum fines of at least 4% of annual turnover in the member state where the violation occurred. Additional remedies include mandatory corrective communications and temporary exclusion from public procurement.

What is greenwashing under EU law?

Greenwashing is making environmental claims that are false, exaggerated, or unsubstantiated. Under the EU Unfair Commercial Practices Directive (which the Green Claims Directive extends), greenwashing is an unfair commercial practice. The Green Claims Directive adds specific substantiation and verification requirements.

EU Green Claims Directive 2026: What Businesses Must Know

Q: What environmental claims are banned by the EU Green Claims Directive?

Generic claims like 'eco-friendly,' 'green,' 'sustainable,' and 'climate conscious' are banned without specific substantiation. Carbon neutrality claims based solely on purchased offsets that don't meet EU quality standards are also prohibited. Any comparative claim without disclosed methodology is non-compliant.

The EU Green Claims Directive requires companies to substantiate environmental claims before making them — not after a complaint is filed. In 2026, this means that any claim like "sustainable," "eco-friendly," "carbon neutral," or "climate positive" must be backed by approved scientific methodology and, in many cases, verified by a third party before it appears on packaging, websites, or advertisements.

For businesses selling to EU consumers, this is a material compliance requirement, not a soft guideline. Non-compliance carries fines of up to 4% of annual turnover in the offending member state.

What the Directive Requires

The Green Claims Directive (formally Directive 2024/825/EU) establishes three core obligations:

Substantiation before use: Environmental claims must be based on recognized scientific methods, cover the full product lifecycle when relevant, and be supported by evidence. Companies cannot use terms like "eco-friendly" without documentation of what makes it so.
Third-party verification: Claims that exceed baseline legal requirements must be verified by an accredited certification body before being communicated. Self-declarations are no longer sufficient for most green claims.
Transparency and comparisons: Comparative claims ("our packaging uses 30% less plastic than the industry average") require that the comparison methodology is disclosed and the reference point is specified.

The directive applies broadly to any environmental claim used in commercial communications — including:

Packaging labels ("100% recyclable", "made from recycled content")
Website sustainability pages and product descriptions
Social media posts and advertising
B2B tender documentation that includes environmental claims
Carbon neutrality or net-zero claims

Generic, vague claims are specifically targeted. Terms like "green," "sustainable," "eco," "nature-friendly," and "climate conscious" without specific substantiation are prohibited.

Carbon Neutrality Claims: Stricter Rules

Carbon neutrality and net-zero claims face particularly strict scrutiny under the directive. Offsets used to claim carbon neutrality must now meet minimum quality standards — permanence, additionality, and verification requirements that disqualify many currently available carbon credits.

The directive effectively prohibits carbon neutrality claims based solely on purchased offsets that don't meet EU criteria. Companies making net-zero claims must demonstrate a credible emissions reduction pathway, not just offset what they emit.

Timeline and Implementation

Date	Milestone
March 2024	Directive formally adopted
March 2026	EU member state transposition deadline
2026–2027	Enforcement begins in early-adopting member states
2028	SME application begins (18-month delay for small businesses)

How to Comply

Audit existing claims: Map every environmental claim across all communication channels. Identify which can be substantiated and which cannot.
Gather evidence: For each claim, identify the scientific standard used for substantiation and document the supporting data. Life cycle assessments (LCAs) are often required.
Obtain verification: For claims that exceed baseline legal requirements, engage an accredited verification body. Build verification into your product launch timeline — it takes 2–6 months typically.
Update or remove non-compliant claims: Claims that cannot be substantiated must be removed or reformulated before enforcement begins in your jurisdiction.

Penalties for Non-Compliance

Member states set their own penalty frameworks, but the directive requires that maximum fines reach at least 4% of annual turnover in the affected member state. Revenue-based fines are designed to make penalties meaningful for large companies that might otherwise absorb fixed-amount fines as a cost of doing business.

Beyond fines, the directive allows for mandatory corrective communications — companies found in violation may be required to publish corrections at their own expense.
