Definition

A project boundary is the delineation, in a greenhouse gas mitigation or removal project, of the sources, sinks, reservoirs and gases included in quantifying the project's emission reductions — together with the spatial and temporal extent of the project activity. Boundary definition is a core methodological step under standards such as the GHG Protocol Project Protocol, Verra VCS and Gold Standard.

Overview

How it is used

Project developers define boundaries in project design documents; validators assess them against methodology rules; leakage assessment typically extends analysis beyond the boundary.

Why it matters

Credit integrity begins with honest boundaries; many historic crediting controversies trace back to boundaries and baselines that excluded inconvenient emissions.
