Corresponding Adjustment
An accounting entry in which the country hosting a project adds the emissions reduction back to its own national inventory, so a buyer abroad can claim it instead. Required under Article 6 of the Paris Agreement for authorised international transfers.
Why a corresponding adjustment matters for carbon credit buyers
Since every country now has a national climate target, a reduction sold overseas would otherwise be counted twice: once by the host country and once by the buyer. A corresponding adjustment removes that overlap, but it depends on a letter of authorisation from the host government, which is administratively slow and limits how much authorised supply exists. CORSIA eligible units require corresponding adjustments, and a growing number of corporate buyers now ask for them voluntarily even though most voluntary market claims do not require one. Authorised credits tend to trade above otherwise comparable credits, so it is worth deciding early whether your specific claim actually needs one.
