Why Climate Claims Need Proof, Not Just Copy

Written by Jack Linnett (Co-founder & CEO)

Trust in climate claims comes from evidence, context, and third-party proof — not slogans.

You can’t win trust on climate with claims alone. If a brand says it is leading, it needs evidence that stands up in context.

Earthmark combines emissions, targets, and external ratings into one benchmarked profile so brands can back up what they say.

That helps reduce greenwashing risk and makes sustainability messaging more credible to shoppers, regulators, and partners.

Replace vague claims with independently backed-up proof.
