Study Finds Over Half of German Green Claims Breach the Incoming EU Directive
TL;DR: A study by Wortliga and Media 4 Nature of 476 German company websites found that more than half of environmental claims would breach the EU's EmpCo directive — which takes effect at the end of September 2026, days away.
What the study found
Reviewing 476 company websites, the Wortliga and Media 4 Nature study concluded that more than half of the environmental claims examined would violate the EU's EmpCo directive. Vague, blanket terms were the single biggest problem: generic claims such as 'nachhaltig' (sustainable) were flagged 100 times.
Unsubstantiated comparatives like 'klimaschonender' (more climate-friendly) appeared 57 times, and CO2-offset-based 'climate neutrality' claims 42 times. The EmpCo directive, which targets exactly this kind of imprecise green messaging, takes effect at the end of September 2026.
Marketing Minute's read: the deadline is now, not later
The uncomfortable headline is not that greenwashing exists — it is the timing. With the EmpCo rules days from taking effect, more than half of the green claims on German websites are already non-compliant. That is not a future risk; it is present exposure that legal and marketing teams need to act on immediately.
The pattern in the data is instructive. The offenders are not elaborate deceptions but lazy, unsubstantiated shorthand — 'sustainable', 'climate-friendly', 'climate-neutral' — used without evidence. The directive is essentially banning vagueness, which means the fix is specificity: claim only what you can prove, and prove what you claim.
What advertisers should do now
Audit every environmental claim across your website, packaging and advertising against a simple test: is it specific, substantiated and verifiable? Blanket terms and offset-based 'neutrality' claims are the highest-risk categories and should be the first to go or be backed with hard evidence.
Beyond compliance, there is a brand argument. As scrutiny rises, vague green claims increasingly read as dishonest to consumers, not just regulators. Precise, evidenced sustainability messaging is becoming a trust asset — the brands that get specific now will look credible while vaguer competitors scramble to rewrite.
Quick FAQ
What did the greenwashing study find?
A Wortliga and Media 4 Nature study of 476 German websites found more than half of environmental claims would breach the EU's EmpCo directive, with vague terms like 'nachhaltig' the most common problem, flagged 100 times.
When does the EmpCo directive take effect?
The EU's EmpCo directive, which targets vague and unsubstantiated green claims, takes effect at the end of September 2026.
What should advertisers do?
Audit every environmental claim for specificity, substantiation and verifiability. Blanket terms like 'sustainable' and offset-based 'climate neutrality' claims are the highest-risk and should be removed or backed with hard evidence.
The story isn't that greenwashing exists — it's the timing. Days before EmpCo takes effect, over half of German green claims are already non-compliant. The directive essentially bans vagueness, so the fix is specificity: claim only what you can prove, and prove what you claim. — Daniel Nikolla, Founder of Merx Marketing
The takeaway: EmpCo is effectively banning vague green claims — 'sustainable', 'climate-friendly', 'climate-neutral' — so audit for specificity now, and treat evidenced sustainability messaging as a trust asset, not just compliance.
