Summary report for the roundtable on “From satellite observation to national GHG inventories: inputs to the Global Stocktake of the Paris Agreement”

A national GHG inventory is an important input for the Global Stocktake (GST), which began from COP26, aiming to assess the collective progress towards achieving the purpose of the Paris Agreement and its long-term goals. All Parties are required to submit a greenhouse gas (GHG) inventory as part of the Biennial Transparency Report (BTR) under the Enhanced Transparency Framework (ETF). Since 2018, the Ministry of the Environment of Japan (MOEJ) and Chuo University in cooperation with the Government of Mongolia has developed a model to estimate CO2 emissions and absorption using GOSAT satellite data in Mongolia. The model results can be used to verify the estimates of GHG inventories.
 
To replicate this experience in other countries, the Institute for Global Environmental Strategies (IGES) and Chuo University organised a roundtable entitled “From satellite observation to national GHG inventories: inputs to the Global Stocktake of the Paris Agreement”, with the support from MOEJ and the Ministry of Foreign Affairs of Japan (MOFA).
 
The roundtable aimed to enhance understanding of the GST, the ETF and their linkage; exchange experiences on how GOSAT satellite data contributed to the preparation of Mongolia’s GHG inventory; and exchange views on how countries could utilise GOSAT satellite data to contribute to the development of GHG inventories.
