Which existing protocol is used to assess greenhouse gas emissions for LEED projects?

The Greenhouse Gas Protocol serves as the standard framework for assessing greenhouse gas emissions applicable to LEED projects. This protocol, developed by the World Resources Institute and the World Business Council for Sustainable Development, outlines methodologies for quantifying and managing emissions across various sectors and is recognized globally. Its comprehensive guidelines allow project teams to measure emissions effectively, enabling them to align their efforts with LEED's sustainability goals.

This protocol's significance lies in its ability to provide consistent and transparent accounting methods for greenhouse gases, essential for achieving credits related to emissions reductions in the LEED rating system. The availability of this structured approach helps projects demonstrate compliance and report their findings accurately, making it integral to the LEED certification process.

The other options, while related to environmental impact assessment and emissions, do not possess the same widespread recognition or focus specifically on greenhouse gas emissions in the context of LEED as the Greenhouse Gas Protocol does.
