The Clean Development Mechanism (CDM) User's Guide is designed as a reference tool primarily for UNDP Programme Managers to learn more about the opportunities and challenges of the CDM and implement projects efficiently and equitably in a variety of national and sectoral contexts. The document addresses issues of climate change and sustainable development including UNDP's CDM strategy and the CDM project cycle.

The manual is not meant to – and cannot – replace the direct expertise that is required to identify, engage and execute project finance and emission transaction contracts under the CDM. Rather, it is intended to provide a holistic overview of the emergent CDM process and the many supportive functions that are required for its success.
