Executive Summary

This guidebook is designed to help the technical staff at GHG programs or initiatives such as GHG registries, and the technical staff at other institutions, such as local business or industry associations and/or consultants, adapt existing GHG Protocol calculation tools to use for a specific GHG program or to more closely reflect national and/or regional circumstances. GHG calculation tools are customized to be made more helpful to companies and/or other entities that may use them and to more accurately collect the quality and type of data that a GHG program is seeking. In addition, working with the future users of these tools while customizing them helps create more effective tools, and builds capacity and momentum for their adoption and implementation by companies and other relevant stakeholders.
