Nevertheless, the design of the mechanism under Article 6.4 should also make sure that it is not be in conflict with the long-term goal of net-zero GHG emissions but even better foster national pathways leading to this objective. Building this into the mechanism requires to shift the focus from short- and mid-term considerations to the long-term perspective in one way or another. This discussion paper explores three different approaches that may help to foster the long-term objective of net-zero GHG emissions in the operationalization of Article 6.4, namely positive and negative lists, additionality with regard to a baseline consistent with both, NDCs and long-term targets, as well as adaptation of existing instruments and criteria from climate finance. The detailed discussion of the ap-proaches shows that the approaches should not be seen as mutually exclusive but rather as comple-mentary to each other. From the analyses, two storylines emerge how to combine aspects of the differ-ent approaches in a reasonable way to foster the long-term objective of net-zero GHG emissions under Article 6.4.
