The mechanism defined in Article 12 of the Kyoto Protocol protocol , through which investors (governments or companies) from developed countries (Annex B) can finance projects to reduce or eliminate emissions greenhouse gases (GHG) in developing countries (without Annex B) and obtain an Emission Reduction Unit (CER) certification. CERs can be attributed to the commitments of the respective developed countries. CDM aims to facilitate two objectives which are support of sustainable development (SD) in developing countries and aid industrialized countries in achieving their emissions obligations in a cost-effective manner.
