United Nations. International carbon crediting mechanism. Article 6.4 Supervisory Body concludes meeting.

Today is Monday, 20 May 2024.


Article 6.4 (A6.4) of the Paris Agreement established a new international carbon crediting mechanism.


A Supervisory Body (SB) is in charge of developing and supervising the requirements and processes needed to operationalize the mechanism that so-called Paris Agreement Crediting Mechanism. Click here to know who from your country is a representative in that SB.


The most recent meeting of that body happened in Bonn, Germany, from 29 April to 2 May 2024.


In a crucial step towards developing a new international carbon market that sets the benchmark for high integrity carbon credits, the SB took a historic step reinforcing the protection of environmental and social human rights, with the introduction of the Appeals and Grievances Procedure.
