Clean Development Mechanism
This booklet provides concise summaries of CDM methodologies and description of methodological tools, approved by the CDM Executive Board. It assists CDM project developers in identifying suitable methodologies for their CDM projects.
When to Use This Tool
This tool is most useful for development impacts assessments focused on:
Learn more about the topics for assessing the impacts of low-emission development strategies (LEDS).
The booklet presents approved methodologies to track emission reductions. Methodologies are grouped in different categories, according to the size and type of potential CDM projects.
How to Use This Tool

Examples of how Clean Development Mechanism has helped people assessing the impacts of low-emission development strategies in countries and regions:

The CDM allows emission-reduction (or emission removal) projects in developing countries to earn certified emission reduction (CER) credits, each equivalent to one tonne of CO2. These CERs can be traded and sold, and used by industrialized countries to a meet a part of their emission reduction targets under the Kyoto Protocol.
The mechanism stimulates sustainable development and emission reductions, while giving industrialized countries some flexibility in how they meet their emission reduction limitation targets.
The projects must qualify through a rigorous and public registration and issuance process designed to ensure real, measurable and verifiable emission reductions that are additional to what would have occurred without the project. The mechanism is overseen by the CDM Executive Board, answerable ultimately to the countries that have ratified the Kyoto Protocol.
In order to be considered for registration, a project must first be approved by the Designated National Authorities (DNA).
Operational since the beginning of 2006, the mechanism has already registered more than 1,000 projects and is anticipated to produce CERs amounting to more than 2.7 billion tonnes of CO2 equivalent in the first commitment period of the Kyoto Protocol, 2008–2012.
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.
