Additionality in the Clean Development Mechanism Why and What?

by Benito Müller

- The rules of the Kyoto Protocol Clean Development Mechanism (CDM) stipulate that activities which would (have) occur(ed) in the absence of the CDM should not be certified as offsets in the form of Certified Emission Reductions (CERs). Why should this be so? By far the most common justification in defence of CDM additionality is that it protects the environmental integrity of the regime. However, this paper observes that, in certain cases, there are indeed reasons for introducing additionality, and in others, reasons for rejecting it.
