Summary of the Results of the 20th Workshop on Greenhouse Gas Inventories in Asia (WGIA20)

Annual workshops have been held since 2003 (excluding 2020 due to the COVID-19 pandemic) to support Asian countries to improve the accuracy of their GHG inventories and to facilitate the enhancement of cooperative relationships in the Asian region.

In this workshop, Mutual Learning sessions on GHG inventories were held. Also, various issues related to the latest inventories submitted by participating countries in their National Communications and Biennial Update Reports, and new reporting formats and tools under the Enhanced Transparency Framework (ETF) of the Paris Agreement were discussed. Group work on the timeline for preparing GHG inventories in view of the submission of the first Biennial Transparency Report (BTR) due by the end of 2024 was held. Methodologies such as how to reflect Carbon Capture and Storage (CCS) in the inventories were also discussed. Through these discussions, the workshop contributed to enhancing capacity for transparency of participating countries and strengthening the network of Asian countries.

In total, 86 participants (including online) attended WGIA20, including government and research representatives of 14 member countries (Bhutan, Brunei, Cambodia, India, Indonesia, Japan, Republic of Korea, Laos, Malaysia, Mongolia, Philippines, Singapore, Thailand, and Viet Nam), in addition to representatives of the Intergovernmental Panel on Climate Change Task Force on National Greenhouse Gas Inventories (IPCC TFI), the Secretariat of the United Nations Framework Convention on Climate Change (UNFCCC), the United Nations Environment Programme (UNEP), the United States of America, Bangladesh, and others.
