Accept any project initiated by the host country as financially additional. Accept any project included in categories that are a priori considered financially additional. No financial additionality criteria. The key component of environmental additionality examined in this paper is the project baseline, or reference case, that estimates what would have happened in the absence of the CDM project. Determining how to accurately and consistently compute environmental additionality presents severe methodological challenges.
Some methodologies are more appropriate for certain sectors than others.
