In Europe, the age of easy green marketing is ending. Under Directive (EU) 2024/825, vague environmental claims such as “green” or “environmentally friendly” are no longer acceptable unless a company can actually demonstrate them. EU countries were required to transpose the directive into national law by 27 March 2026, and the rules will apply from 27 September 2026. In practice, this means that sounding sustainable is no longer enough; businesses need evidence. (energy.ec.europa.eu)
The crackdown did not appear out of nowhere. The European Commission says 53.3% of environmental claims it examined were vague, misleading or unfounded, and 40% had no supporting evidence. It also notes that consumers face a jungle of labels: more than 230 sustainability labels and 100 green energy labels across the EU, often with very uneven transparency. That helps explain why Brussels has moved from encouraging green language to policing it. (environment.ec.europa.eu)
The new rules are unusually concrete. The EU has revised its blacklist of unfair commercial practices to ban generic claims without proof, misleading sustainability labels not based on certification schemes or public authorities, and claims about an entire product when only one part is actually greener. The rules also target climate claims based on offsetting, such as presenting a product as “climate-neutral” because emissions were compensated elsewhere. In other words, “green” is becoming less of a mood and more of a testable statement. (consilium.europa.eu)
At the same time, the tougher follow-up law, the Green Claims Directive, has entered a murkier phase. The Commission proposed it in March 2023 to require more systematic substantiation of voluntary environmental claims; the Council agreed its position in June 2024, and trilogue talks began in January 2025. But on 20 June 2025, the Commission announced that it intended to withdraw the proposal, and a scheduled trilogue on 23 June 2025 was cancelled. Even so, the European Parliament’s Legislative Train reported on 20 April 2026 that the file was still listed as pending in the 2026 Commission Work Programme. So the direction of travel is clear even if the politics are messy: in Europe, anyone who wants to call a product “green” should be ready to prove it. (consilium.europa.eu)
