EU Green Claims Rules Under EmpCo Force Fashion Brands to Prove Sustainability

The reality of Directive (EU) 2024/825, known as the EmpCo Directive (Empowering Consumers for the Green Transition), has arrived. It tightens the rules around environmental and sustainability claims in commercial communications, and for fashion brands still leaning on vague green language, the deadline is uncomfortably close.

It applies to every fashion retailer and brand selling to EU consumers, whether a two-person label in Ghent or a growing multi-brand store in Amsterdam, and the ultimate deadline to avoid fines is September 27, 2026. All member states must have transposed the requirements into national law by March 27, 2026, after which the new rules become binding for all companies from September 27, 2026.

In plain terms, EmpCo tightens rules around environmental and sustainability claims by defining what counts as greenwashing — not just the obvious lies, but also the vague, unverifiable, or misleading language that has become standard in fashion marketing. Terms like "eco-friendly," "sustainable," "conscious," "green," or "climate-neutral" are now legally prohibited if brands cannot back them up with concrete, verifiable evidence. The scope is broader than many expect: environmental, social, and circularity claims are the directive's main features, meaning that hangtag copy about ethical production or fair wages is subject to the same scrutiny as carbon footprint claims.

The EmpCo Directive clarifies what greenwashing means: any environmental claim that is inaccurate, unsubstantiated, or unverifiable falls under this category, and this has consequences even if a company is genuinely sustainable. If claims or sustainability labels are not carefully documented, they can still be considered greenwashing — it is not just the action itself that matters, but also the proof.

The practical rewrite is more straightforward than it sounds. COSH!, which published a detailed explainer for fashion brands on March 26, 2026, offers a clear framework: instead of "We produce ethically," the compliant version reads, "All our garments are produced in our own atelier in Lisbon, where workers are paid above the national living wage and conditions are audited annually by [recognised third-party body]." The structure is easy to apply: name the specific claim, explain the evidence, and acknowledge the limitations. Applied to carbon claims, that same logic means replacing "We are a climate-neutral brand" with a statement that specifies the percentage of emissions actually reduced, the certified offset scheme used for the remainder, and an explicit acknowledgment that offsetting does not equal zero emissions.

The directive requires concrete, verifiable plans for all environmental claims and provides for independent third-party verification. Particularly challenging: claims that rely solely on compensation will be prohibited, a real issue for many globally oriented marketing strategies.

Germany is moving fastest among member states. The country is implementing EmpCo through the Drittes Gesetz zur Änderung des UWG (Third Act Amending the Act Against Unfair Competition). The Bundestag adopted the proposal on December 19, 2025, and the Bundesrat sat on January 30, 2026. Publication is expected shortly, with the first provisions around misleading future claims coming into force on June 19, 2026, and the full package following on September 27, 2026. The Netherlands published its implementation proposal on December 15, 2025, and it is currently progressing through the House of Representatives; Dutch authorities, particularly the ACM (Authority for Consumers and Markets), have already been actively enforcing green claims under existing law.

EmpCo sits within a wider web of EU compliance obligations. As CSR-Tools notes, for companies the directive initially means "in addition to CSRD, ESRS, CSDDD and co., even more regulation, but ultimately also fairer competitive conditions and more credibility in sustainability communication." The directive amends the Unfair Commercial Practices Directive and brings green marketing claims under the same legal teeth already applied to false advertising.

The companion Green Claims Directive, proposed by the European Commission in 2023 and designed to add life cycle-based evidence requirements using the Product Environmental Footprint methodology, remains a separate and currently stalled proposal. As Lidia Lüttin noted in a January 2026 policy analysis, its legislative process is paused, with the European Commission announcing an intention for withdrawal on June 20, 2025, amid political pressure and internal disagreements. The practical takeaway is clear: don't wait for the Green Claims Directive to be finalized. EmpCo is already law and requires brands to clean up marketing, packaging, and product claims now.

Even brands that already market responsibly will need to change practices: terms like "green," "sustainable," "eco-friendly," or "energy-saving" will be banned unless supported by recognized proof of excellent environmental performance. Without applicable eco-labels or certification systems, companies must use specific, measurable statements, such as "Packaging biodegrades in home compost within 30 days," instead of a vague "biodegradable" — backed by a realistic plan and third-party validation.

For brands that have spent years doing the actual work, the compliance burden is real but the competitive upside is significant. Those who can document their claims precisely will hold a legal and reputational advantage over competitors still hiding behind a "conscious collection.
