The Paris Agreement's Article 6 establishes a new framework for using international car-bon market mechanisms. The primary objective of the approaches under Article 6 is to facilitate voluntary cooperation between Parties, to allow for higher ambition and to pro-mote sustainable development and environmental integrity. Moreover, Article 6.4 establishes the concept of delivering an "overall mitigation in global emissions" (OMGE).

This paper addresses questions that have been raised in relation to OMGE. It draws on a study conducted by Lambert Schneider and NewClimate Institute.
