The goal of this project is to assist Malaysia in the mainstreaming and integrating of climate change considerations into national and sectorial development process, giving continuity to the institutional and technical capacity strengthening process for climate change. The specific objective of the project is to assist Malaysia in the preparation of its Second Biennial Update Report (BUR2) for the fulfilment of the obligations under the United Nations Framework Convention on Climate Change (UNFCCC). The project will be carried out by the Ministry of Natural Resources and the Environment (MNRE) and will build upon previous reporting commitments to the UNFCCC, namely the National Communications and the Biennial Update Report. The Second Biennial Update Report will focus on five components, (a) Institutional arrangements and national circumstances, (b) Greenhouse gas inventory report, (c) Mitigation action and their effects, (d) Constraints and gaps, and related financial, technical and capacity needs and support, and (e) Preparation and submission of the BUR2 including the project's monitoring and reporting.The expected outcomes of the project are:•Institutional arrangements strengthened, information on national circumstances updated;•National GHG inventory strengthened and described and inventory data updated;•Increased capacity in identifying and quantifying mitigation actions and their effects, and in MRV;•Constraints and gaps, and related financial, technical and capacity needs and support identified; and solutions for addressing the needs proposed; and•Development, publication and dissemination of the BUR2 report.The BUR2 is envisioned to act as a key tool to assist the national decision making process, as the continuous and solid climate data obtained through the process of biennial update reporting plays a role in informing the policy design process.
