Methodologies in the Verified Carbon Standard (VCS) Program set out detailed procedures and requirements that VCS projects must follow to quantify GHG emission reductions and/or carbon dioxide removals and have Verified Carbon Units (VCUs) issued. Each methodology specifies applicability conditions and provides criteria for defining the project boundary, identifying the baseline scenario, assessing additionality, quantifying reductions and/or removals, and establishing monitoring procedures and requirements.
