Vietnam National Climate Change Strategy (2011) and other national policies recognize the significance of GHG emission monitoring and inventory. Department of Meteorology, Hydrology and Climate Change (DMHCC) under Ministry of Natural Resources and Environment (MONRE), appointed as national focal point for GHG emission monitoring and inventory, has been chairing the team to develop National Communications, Biennial Updated Reports and Intended Nationally Determined Contributions. These national reports include results from National Inventory Report (NIR). However, the NIR development encountered various difficulties, leading to limited supports to the implementation of NAMAs and low-carbon cities. This is due to the lack of perception and understanding of GHG inventory at all levels. With high ambitious goals in INDC, Vietnam needs to improve perception and capacity for leaders and practitioners on GHG emission monitoring and inventory. This project proposes the immediate solution through two main activities: (1) the development of a comprehensive set of training materials on GHG monitoring and inventory, NAMAs and low-carbon pathways, (2) organization of regional training workshops for national and provincial leaders in the three regions in Vietnam. The outcomes of this project will be significant enhancement of perception and capacity for policy makers and practitioners at all levels on GHG monitoring and inventory. The project will also motivate neighboring areas to follow.
