VCS methodologies impact a variety of aspects of everyday life. Click on any of the icons below to find the best one to suit your needs. However, a VCS project doesn’t necessarily need to employ a VCS methodology; project developers may also use any approved United Nations Clean Development Mechanism (CDM) or Climate Action Reserve (CAR) methodology, with the noted exception of CAR’s forest protocol.
The current and valid version of a methodology must always be used. From time to time, a methodology may be revised, withdrawn or put on hold. To learn about the grace periods that apply in such cases, see the main methodologies page.
