This note aims to inform countries and negotiators discussing the establishment of new infrastructure under Article 6 of the Paris Agreement regarding existing shortcomings of registries and project databases that should be improved. It can also serve voluntary market actors, in particular programmes, to improve their existing platforms and remedy some of the shortcomings identified.

This note does not aim to provide an exhaustive list of all the information that should be included in registries and project databases, but rather addresses a few specific lessons from existing practices.
