Article 6 (Paris Agreement)
The section of the Paris Agreement governing how countries cooperate on emissions reductions, including transferring them internationally. It sets the rules for authorisation, corresponding adjustments, and a UN supervised crediting mechanism.
Why Article 6 of the Paris Agreement matters for carbon credit buyers
Article 6 is the bridge between the voluntary market and national climate accounting. Article 6.2 covers bilateral arrangements between countries, while Article 6.4 establishes the centrally supervised Paris Agreement Crediting Mechanism that succeeds the Kyoto-era Clean Development Mechanism. For buyers, the practical question is whether a credit has been authorised for international transfer, because authorisation triggers a corresponding adjustment and changes both what can be claimed and what the credit costs. The framework was agreed at COP26 and the operating rules were finalised at COP29, so eligibility details are still settling and are worth rechecking before a large purchase.
