Your product page says "eco-friendly." Your packaging says "sustainable." Your Instagram bio says "committed to a greener planet."
Starting September 2026, every one of those claims could be illegal in the European Union — unless you can prove them with verified data.
The EU Green Claims Directive (formally: Directive on substantiation and communication of explicit environmental claims) is a regulation that makes it illegal to make environmental claims about products without scientific evidence and approved methodology to back them up.
This isn't a guideline. It's not a recommendation. It's enforceable law with real penalties.
The directive was adopted to combat greenwashing — the practice of making vague, misleading, or unsubstantiated environmental claims to attract eco-conscious consumers. Studies showed that 53% of environmental claims in the EU were vague, misleading, or unfounded, and 40% had no supporting evidence at all.
The EU decided to fix that with legislation.
The directive covers any explicit environmental claim made in commercial communications to consumers in the EU. This includes:
The directive applies to claims made anywhere EU consumers can see them: - Product packaging and labels - Website and product pages - Social media posts and ads - Marketplace listings (Amazon EU, Zalando, ASOS) - Press releases and marketing materials - Point-of-sale displays - Influencer partnerships (the brand is liable, not just the influencer)
To make a green claim legally, you must:
Your claim must be based on widely recognized scientific evidence, using methodologies that are: - Internationally accepted (ISO 14040/14044 for lifecycle assessment, PEF for carbon footprint) - Relevant to your product category (textile-specific methods for apparel, electronics-specific for gadgets) - Current (data and studies must reflect current production methods, not historical averages)
The environmental benefit you're claiming must be significant — not trivial or marginal. Saying "we reduced packaging by 5%" is technically true but may not meet the significance threshold if the environmental impact of packaging is minor compared to the product itself.
Claims about environmental performance must consider the full product lifecycle: raw material extraction, manufacturing, transportation, use phase, and end-of-life disposal. Cherry-picking one favorable stage while ignoring others is non-compliant.
Comparative claims ("50% less carbon than the industry average") must use equivalent comparison points — same product category, same methodology, same functional unit. You can't compare your t-shirt's carbon footprint to a winter coat's.
The evidence supporting your claim must be accessible to consumers — either directly on the product (QR code linking to a data page) or available upon request within a reasonable timeframe.
This is where the Digital Product Passport (DPP) becomes your best friend. A DPP provides the structured, verified data that substantiates your green claims. Without one, you're making claims you can't prove.
The Green Claims Directive classifies violations as unfair commercial practices, which triggers penalties under existing EU consumer protection frameworks:
For a brand doing €5 million in EU sales, a 4% penalty means €200,000 in fines — plus the cost of removing claims, updating packaging, reprinting labels, and corrective advertising. Total exposure can easily reach €300,000–€500,000 for a mid-size brand.
For brands doing €500,000 or less in EU sales, the direct fines are smaller, but marketplace delisting can be existential. If Amazon EU removes your listings, you may lose your primary EU sales channel overnight.
| Date | What Happens |
|---|---|
| September 2026 | Green Claims Directive takes effect in EU member states |
| Late 2026 | Enforcement begins; marketplace compliance requirements tighten |
| 2027 | First major enforcement actions expected |
| 2027–2028 | DPP mandate for textiles provides the data infrastructure for green claims compliance |
The directive takes effect in September 2026, but marketplace enforcement will start earlier. Amazon EU, Zalando, and other platforms are already updating their policies to require substantiation for environmental claims. Expect listing reviews to begin in Q3 2026.
The simplest way to comply: stop making vague claims and start sharing data. Instead of "sustainable," say "made from 92% organic cotton, manufactured in Portugal, 3.2 kg CO2e per unit." Instead of "eco-friendly packaging," say "packaging is 100% recyclable in curbside programs in all EU member states."
Data is defensible. Adjectives are not.
