A methodology for conducting such inventories was developed by the OECD Environment Directorate, the International Energy Agency (lEA), and the IPCC Working Group I Techni-cal Support Unit and was proposed as the standard methodology as required under the Convention.In order to test and further refine the method, the UNEP Atmosphere Unit, working in collaboration with the UNEP Global Environment Facility (GEF), implemented a series of nine complementary national studies using these "IPCC Guidelines for National Greenhouse Gas Inventories". This report is one of the nine technical reports resulting from this effort. DS UN Environment Document Repository RD Sep 23, 2026
