The objective of this project is to enable Belize to prepare its Fourth National Communication (FNC) under decision 17/CP7 and the First Biennial Update Report (BUR) under decision 2/CP17 of the United Nations Framework Convention on Climate Change. To facilitate Fourth communication/ BUR delivery, the project will employ a strategy which:•Identifies relevant institutional structures and arrangements which provides a basis for cooperation and information exchange. This strategy is also key for continuity of processes and for the enabling of consistent BUR reporting. •Establishes national foundations for quality control and activity validation, introducing additional elements of rigor into this and subsequent GHG inventories.•Amends national mechanisms and processes to ensure the effective integration of gender perspective into key relevant process outputs. The Fourth National Communication and First Biennial Update Report information on national circumstances will be updated considering all new studies, projects and research conducted since this communication and BUR was prepared. It includes an update of the country's characterization in terms of geography, demography, natural resources, climate, education, social and cultural aspects, and macroeconomic parameters such as employment, income and services. It will also include characterization of specific sectors such as agriculture, forestry, water resources, fisheries, coastal and marine resources, energy, wastes, tourism, transportation, human settlements, and health. Special attention will be given to the new information and data on the sectors that contribute the most to greenhouse gas emissions.The enabling activity supporting FNC/ BUR preparation is being extended to support an analysis of how the described national circumstances can affect Belize's capacity to address Climate Change mitigation and adaptation. The update of institutional arrangements and structures pertinent to preparation of the national communications and biennial update reports ensure national inventories with greater transparency, coherence, comparability, exhaustiveness and accuracy.
