The GHG Assessment Boundary delineates the GHG sources, sinks, and reservoirs (SSRs) that must be assessed in order to determine the total net change in GHG emissions caused by a GHG reduction project. GHG Assessment Boundaries are defined for each type of project activity addressed in a Reserve protocol. The GHG Assessment Boundary is not a boundary related to a project’s physical location. Instead, it encompasses all SSRs that could be significantly affected by a project activity, regardless of where such SSRs are located or who owns or controls them.
