This report outlines the preliminary findings of a collaborative satellite analysis to estimate Australia’s coal mine emissions for the 2020 and 2021 financial years. It utilised wind-rotation methods using TROPOMI satellite data across six clustered coal mining regions. These regions accounted for 79% of Australia’s black coal production, and more than 90% of Australia’s metallurgical coal production. The estimates are compared against state-level and national coal mine methane emissions from National Greenhouse Accounts.
