Catalog of Approved Methodologies

If a current methodology does not fit, project developers can choose to develop their own methodology through the VCS methodology approval process.

To ensure VCS remains the most robust and respected voluntary standard in the world, VCS periodically reviews approved methodologies to ensure they conform to current requirements, international best practices and scientific consensus. During this process, if it is determined that a methodology must be updated, revised or withdrawn, a grace period will apply for projects currently using the methodology. The status of each methodology is always displayed on the methodology page of the website.

VCS projects must comply with the grace periods and rules set out by the relevant GHG program. For example, if a CDM methodology is withdrawn, a VCS project using that methodology must issue the project validation report by the CDM deadline for requesting project registration.
