The CDM Methodology Booklet summarizes each approved methodology into just one page that includes an innovative diagrammatic representation. Use the booklet for inspiration for creating a CDM project, or to find the methodology needed to implement your CDM project idea.

"Environmental integrity is at the heart of the CDM and methodologies have a major role in ensuring this integrity. Methodologies are required to establish a project’s emissions baseline, or expected emissions without the project, and to monitor the actual ongoing emissions once a project is implemented. The difference between the baseline and actual emissions determines what a project is eligible to earn in the form of credits. Methodologies are essential when quantifying emission reductions in an uncapped environment on a project-byproject basis."

"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 locales covered by the CDM. Hence this publication, designed to guide users through the complex world of CDM methodologies."

"By clearly summarizing, classifying and illustrating the methodologies available under the CDM, and then enhancing the means by which to search those methodologies, this publication serves to guide potential CDM project participants. It is my fervent hope, and that of the team that developed this work, that it will contribute to a rise in the number of CDM projects, increase the use of methodologies that directly benefit women and children, and enhance the regional distribution of projects, which is a key desire of Parties to the Kyoto Protocol, the CDM Executive Board and this secretariat."
