comparative advantage for the GEF is related to it being the only United Nations organization with a mandate to coordinate the work of the United Nations in the area of environment for which the core business is the field of environment. UNEP also provides the GEF with a range of relevant experiences, proof of concept, testing of ideas, and the best available science and knowledge upon which it can base its investments. It also serves as the Secretariat to three of the Multilateral Environmental Agreements (MEAs), for which GEF is the/a financial mechanism.
