22 November 2010: The UNFCCC Secretariat has published a Clean Development Mechanism (CDM) Methodology Booklet summarizing, classifying and illustrating the methodologies available under the CDM.

Each approved CDM methodology is summarized in one page, with a diagrammatic representation of the methodology. Each such methodology summary sheet provides the following information: typical project(s) to which the methodology is applicable; type(s) of greenhouse gas (GHG) emission mitigation action; important conditions for application of the methodology; key parameters that need to be determined or monitored; and visual description of baseline and project scenarios. The aim of the Booklet is to facilitate the initial selection of potentially applicable methodologies, and is intended for use by audiences interested in the CDM, particularly potential CDM project developers who already have an idea of the mitigation projects they intend to implement.
