What evidence do carbon, offset, and climate claims need?
Climate claims need the normal explicit-claim file and a separate climate evidence file. From 27 September 2026, national measures implementing Directive (EU) 2024/825 prohibit claims that a product has a neutral, reduced, or positive greenhouse-gas impact based on offsets outside the product value chain. Existing UCPD rules can still apply to misleading offset claims before that date.
For trader climate claims using carbon credits, the evidence should separate the trader's greenhouse-gas emissions and reductions from any credits. It should identify the quantity of credits in tCO2e, the period, whether credits are reductions or removals, the scheme, registry, verification and certification route, and, for offset claims, the percentage of total greenhouse-gas emissions balanced out by credits.
- Separate actual emissions and reductions from carbon credits, offsets, removals, and contribution claims.
- Keep the greenhouse-gas inventory boundary, time period, scopes covered, calculation method, emission factors, source data, and assurance or verification record.
- For credits, retain quantity in tCO2e, reduction-or-removal classification, permanence or temporary status where relevant, scheme, registry, certificate, serial or cancellation evidence, and double-counting controls.
- For future climate claims, retain the time-bound commitment, pathway, value-chain actions, monitoring process, and evidence that the claim does not rely on offsets as a substitute for own-operation and value-chain reductions.
Supports the specific evidence requirements for climate-related trader claims, carbon credits, offset claims, and separate disclosure of emissions and credits.
Supports separating greenhouse gas offsets from greenhouse gas emissions and explaining whether offsets relate to reductions or removals.
