Article 6 has been flagged as containing some of the key provisions of the Paris Agreement. Broadly, it outlines the cooperative approaches that parties can take in achieving their nationally determined carbon emissions reductions. In doing so, it helps establish the Paris Agreement as a framework for a global carbon market. Article 6 is the only important part of the Agreement yet to be resolved; negotiations in 2019 did not produce a result. The topic is now expected to be settled during the 2021 negotiations in Glasgow.
