How EmpCo from 27 September 2026 changes German property listings

What changes on 27 September 2026

The EU directive known as EmpCo (Directive (EU) 2024/825) becomes applicable across Member States from 27 September 2026; it amends EU consumer law to restrict misleading environmental marketing and adds a list of prohibited “green” claims to unfair commercial practices law. ([eur-lex.europa.eu](https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=celex%3A32024L0825&utm_source=openai))

Germany implemented the directive into national law by updating the Gesetz gegen den unlauteren Wettbewerb (UWG) earlier in 2026; the amended UWG provisions for environmental claims apply from the EmpCo application date. Buyers seeing German property advertisements after 27 September 2026 must therefore read marketing claims against this legal standard.

Which listing claims are directly affected

EmpCo targets broad, generic environmental claims. Words and images that imply a product, service or business is generically “green”, “eco”, “environmentally friendly” or “climate‑neutral” are covered and can be prohibited unless the trader can demonstrate a recognised excellent environmental performance relevant to the claim. The directive explicitly links such generic claims to that evidential requirement. ([eur-lex.europa.eu](https://eur-lex.europa.eu/eli/dir/2024/825/oj/eng/pdf?utm_source=openai))

The legal definition of an environmental claim in the EU text is wide: it includes any message in any form — text, pictorial, graphic or symbolic — that states or implies a positive or neutral environmental impact. That means marketing copy, a logo or even a brand name used to convey an environmental advantage can fall within the rule. ([eur-lex.europa.eu](https://eur-lex.europa.eu/eli/dir/2024/825/oj/eng/pdf?utm_source=openai))

What counts as acceptable evidence

EmpCo does not leave evidence undefined. The EU and Commission guidance point to narrow routes that allow continued use of certain environmental words: recognised Type‑I ecolabels (for example national or regional labels of the Blue Angel type), the EU Ecolabel and "top‑performance" under existing EU law (for goods and their energy labelling regimes). A seller who relies on a label should be able to name the scheme, produce a current certificate or verifier report, and show that the certificate scope matches the advertised claim. ([empcodirective.eu](https://empcodirective.eu/commission-faq-june-2026?utm_source=openai))

The Commission’s Q&A and technical guidance also warn that a certificate alone does not automatically validate every related marketing phrase — the scope of the certificate and the specific performance measured must match the claim. Buyers should therefore ask for the certificate number, the verifier’s identity and the concrete measurement or threshold that supports the advertised wording. ([commission.europa.eu](https://commission.europa.eu/document/download/3c257883-bb2a-4dd9-a6dc-501d587bb34f_en?filename=faq-empowerting-consumers-gtd.pdf&utm_source=openai))

A practical checklist for foreign buyers

1) If an ad says “climate‑neutral”, “CO2‑neutral”, “green” or similar: ask for the recognised scheme or legal basis that proves the claim, the certificate number and the verifier’s report showing what was measured and when. If the seller cannot produce matching evidence, treat the claim as marketing only. ([empcodirective.eu](https://empcodirective.eu/banned-green-claims?utm_source=openai))

2) For statements about solar (PV) or onsite generation: request documentation that links generation to building use (metering data or an independent verifier report) and any third‑party certificate relied on. EmpCo’s scope makes pictorial or brand‑style claims subject to the same tests as written claims. ([eur-lex.europa.eu](https://eur-lex.europa.eu/eli/dir/2024/825/oj/eng/pdf?utm_source=openai))

3) Where a seller points to an ecolabel or a national mark: ask whether the label is a recognised Type‑I scheme or the EU Ecolabel and ask to see the current certificate. A certificate whose scope is narrower than the ad will not rescue a generic phrase. ([empcodirective.eu](https://empcodirective.eu/commission-faq-june-2026?utm_source=openai))

4) When in doubt, ask the selling agent or notary for written substantiation before signing. If a claim looks material to price or buyer decisions, obtain independent advice (legal or technical) — this article is guidance, not legal advice.

Risks and enforcement

Enforcement of EmpCo’s rules sits with national authorities and courts under the amended unfair practices framework; Germany already amended the UWG to follow the directive. That means misleading or unsupported environmental marketing on a listing can be subject to national enforcement measures from the application date. Cross‑border buyers should therefore assume that a straightforward “green” label in an online ad carries legal risk unless substantiated.
