CDM Methodologies

Methodologies Booklet

CDM Methodology Booklet: The function of methodologies is easy to grasp, but the methodologies themselves can be quite complex. They are necessarily diverse in their composition and application in order to accommodate the wide range of activities and areas covered by the CDM. By clearly summarizing, classifying and illustrating the methodologies available under the CDM, and enhancing the means by which to search those methodologies, the CDM Methodology Booklet aims to guide potential CDM project participants through the complex world of methodologies and assist them in identifying methodologies suitable for their project activities.
