The purpose of the CDM is to promote clean development in developing countries, i.e., the "non-Annex I" countries (countries that aren't listed in Annex I of the Framework Convention). The CDM is one of the Protocol's "project-based" mechanisms, in that the CDM is designed to promote projects that reduce emissions. The CDM is based on the idea of emission reduction "production" (Toth "et al"., 2001, p. 660). These reductions are "produced" and then subtracted against a hypothetical "baseline" of emissions. The baseline emissions are the emissions that are predicted to occur in the absence of a particular CDM project. CDM projects are "credited" against this baseline, in the sense that developing countries gain credit for producing these emission cuts.
