    Problematic environmental terms in advertising

    Which terms are risky under the EmpCo Directive – and how to replace them with verifiable wording.

    From 27 September 2026, generic environmental claims without recognised excellent environmental performance and neutrality claims based on offsetting are not allowed. That affects many common terms.

    „climate neutral“

    High risk

    Claims of climate neutrality based on offsetting are not allowed under the EmpCo Directive.

    „CO₂ neutral“

    High risk

    As with “climate neutral”: if the claim rests on offsetting, it is not allowed from September 2026.

    „sustainable“

    Only with specifics

    Risky as a generic environmental claim without specifics; usable with a clear reference and evidence.

    „eco-friendly“

    High risk

    Named in the Directive itself as an example of a generic environmental claim.

    „green“

    Only with specifics

    As an environmental promise (“green hotel”) it is a generic claim; as a colour or place name it is unproblematic.

    „eco“

    Only with specifics

    Protected for food (EU organic regulation); outside that it is a generic environmental claim.

    „climate-friendly“

    High risk

    A neutrality-adjacent claim: without a verifiable reduction path it cannot be substantiated.

    „biodegradable“

    Only with specifics

    Only defensible with a named standard and conditions – “degradable” depends on time, temperature and place.

    „green advertising“

    Only with specifics

    An umbrella term without legal definition – what counts is the individual claim behind it.

    „ecological“

    Only with specifics

    For food it is tied to organic certification; in other contexts it is a generic environmental claim.

    „carbon footprint“

    Only with specifics

    Usable, but only with a disclosed method, a boundary and a date.

    „regional“

    Only with specifics

    No legal definition of the radius – readers assume much shorter distances than suppliers often deliver.

    „climate-sparing“

    High risk

    Sounds measurable but is not: without a stated reduction, the claim stays unsubstantiated.

    „close to nature“

    Only with specifics

    A feeling, not a claim – dangerous only when it suggests a verified environmental benefit.
