The market

The voluntary carbon market

A fast-maturing market where companies buy credible credits to meet their climate goals.

1 credit = 1 tonne of CO₂

One tonne of CO₂ avoided, reduced or removed from the atmosphere, measured, verified and certified by an independent standard.

Voluntary ≠ regulated

Companies buy credits of their own accord, beyond any obligation. This is distinct from regulated schemes like the EU-ETS.

The verifiers

Certification is what creates value

A credit is only worth the trust it inspires. Standards and integrity bodies guarantee quality: rigorous measurement (MRV), additionality, traceability.

No double counting

A reduction already funded or paid for elsewhere, a subsidy, another scheme, or a credit already claimed, cannot also generate a voluntary credit. Additionality required: no double payment, no double counting. Reductions covered by a regulatory market (EU-ETS), already subsidized, or already counted toward your own targets are excluded.
