This report summarizes information on climate change country studies received by the United Nations Environment Programme (UNEP) Secretariat, supplemented with information from other sources. The term "climate change country study" is used here to mean any official national study on climate change, including greenhouse gas emissions inventories, impacts assessments, and emissions mitigation analyses. Numerous other studies, undertaken by institutions in various countries, are not listed here since either they have not been endorsed as official national studies or they are global or sub-national in coverage.
