GEF, being a major multilateral agency and being an operating entity of the financial mechanism of the UNFCCC, has a critical role to play in promoting interventions aimed at reducing GHG emissions. In this context STAP initiated a study to provide information and guidance on options for advancing sustainable low-carbon transport during GEF-5. The report was prepared by Holger Dalkmann (TRL) and Cornie Huizenga (SLoCaT). Several of the members of Bridging the Gap and SLoCaT provided inputs and comments.
