On 27 September 2026, the language of European e-commerce changes. Words like 'sustainable', 'eco-friendly', 'green' and 'climate neutral' will still appear on product pages, but only if the retailer can prove what they mean. The EU's EmpCo Directive (2024/825), formally the Empowering Consumers for the Green Transition directive, makes vague environmental claims unlawful in business-to-consumer communication unless supported by verifiable, independent evidence. The shift is structural: it turns green marketing from a matter of brand discretion into a compliance obligation with real legal teeth.
What the directive actually bans
The core prohibition targets generic environmental claims made without substantiation. 'Environmentally friendly', 'green', 'sustainable', 'climate-friendly', 'climate neutral' and 'climate positive' all fall under the ban unless the claim rests on a recognised, verifiable basis and the stated benefit genuinely and demonstrably distinguishes the product. Internal scoring systems or proprietary indices will not suffice. The standard is objective, transparent and auditable criteria.
The same principle applies to social claims. Phrases such as 'fairly produced' or 'manufactured with human dignity' become legally risky without a clearly defined scope, publicly accessible criteria and external verification. The directive treats vague social promises with the same scepticism as vague environmental ones.
The end of offsetting-based climate neutrality
Among the most consequential provisions is the explicit prohibition on climate-neutral claims that rely primarily on carbon offsets. The widely used formulation 'climate neutral (through compensation)' will no longer be permissible, even with a transparency disclaimer. Retailers wanting to discuss climate impact must demonstrate real emission reductions within their own operations or supply chain, specify what has been achieved and over what period, and avoid the word 'neutral' as a blanket promise.
This strikes at the heart of how many European brands have marketed themselves. For years, companies have purchased carbon credits and labelled products climate neutral on that basis. The directive says that practice, in its current form, ends this autumn.
Self-made labels become a legal hazard
The directive also tackles the proliferation of sustainability seals. Environmental and social labels may only be used if they are based on certified systems with transparent criteria and independent oversight, or are issued by public authorities. A retailer drawing a leaf icon and calling it 'eco' without a rigorous certification framework behind it is exposing itself to enforcement action.
Future-oriented claims face similar scrutiny. A pledge to become 'climate neutral by 2030' is only permissible if accompanied by a concrete, measurable and publicly accessible plan, including interim targets, a clear action pathway and independent verification. Empty roadmaps, however aspirational, will not pass muster.
Durability and repairability disclosures
Beyond marketing claims, the directive introduces mandatory pre-purchase information on product longevity. Retailers must disclose the availability of software updates for goods with digital elements, specify the period for which updates will be provided, and make information on durability and repairability visible before the consumer completes a purchase. These obligations extend to product detail pages, checkout information and general terms.
The scope is broad. E-commerce sites must adapt not just product descriptions but also filter functions, campaign materials, badges and terms and conditions pages. Any consumer-facing communication that touches sustainability, longevity or environmental impact falls within the directive's reach.
Germany moves early
EU member states were required to transpose the EmpCo provisions into national law by 27 March 2026. The German Bundestag has already done so, making Germany one of the first jurisdictions where the directive has full legal force. Other member states are at varying stages of implementation, but the 27 September enforcement date applies EU-wide regardless of national legislative progress. The directive text on Eur-Lex sets out the full framework.
Penalties and enforcement
Non-compliance carries real consequences. Violations can result in formal warnings, cease-and-desist orders and fines. In Germany, where consumer protection associations are already active in pursuing misleading advertising claims, the directive gives them a considerably sharpened legal instrument. Carsten Föhlisch, a legal expert at Trusted Shops, the Cologne-based e-commerce trust mark provider, put the practical implication plainly: terms like 'climate neutral' or 'sustainable' will only be permissible in future if companies can verifiably demonstrate what exactly is meant and what the claim is based on. For online shops, he said, this means auditing existing claims, evidence and labels for robustness, and building internal processes so that statements are legally and substantively reviewed before publication.
What retailers must now do
The compliance task is not trivial. Retailers need to audit every product page, badge, filter, campaign and checkout flow for claims that could fall foul of the new rules. Where a claim survives scrutiny, the evidence base must be documented and accessible. Where it does not, it must be removed or replaced with specific, measurable statements that identify the product property, the source and the time period.
Sustainability labels must be linked to their certification criteria, the inspecting body and the validity period. Only independent, established systems qualify. Lifecycle claims must be explicitly scoped: if a benefit applies only to the use phase, that limitation must be stated clearly, not implied.
