The Clean Development Mechanism (CDM), defined in Article 12 of the Protocol, allows a country with an
emission-reduction or emission-limitation commitment under the Kyoto Protocol (Annex B Party) to implement an
emission-reduction project in developing countries. Such projects can earn saleable certified emission
reduction (CER) credits, each equivalent to one tonne of CO2, which can be counted towards meeting Kyoto
The mechanism is seen by many as a trailblazer. It is the first global, environmental investment and credit
scheme of its kind, providing a standardized emissions offset instrument, CERs.
A CDM project activity might involve, for example, a rural electrification project using solar panels or the
installation of more energy-efficient boilers.
The mechanism stimulates sustainable development and emission reductions, while giving industrialized
countries some flexibility in how they meet their emission reduction or limitation targets.
