This document discusses GHG accounting methods and requirements for GEF projects. It notes that GEF supports countries in meeting UNFCCC obligations and requires projects to describe baselines and incremental impacts. GEF requires reliable estimates of direct and indirect GHG reductions from relevant programs and projects. Approved methodologies exist for estimating reductions from transportation, energy efficiency, and renewable energy projects, with methodologies being developed for urban and LULUCF projects. Projects with climate change, land degradation, or sustainable forest management funding must estimate GHG reductions using accepted methodologies. GEF seeks multiple benefits from projects and accepts standard GHG accounting methods used by implementing agencies.
