Before revision:  Unlike other emerging estimates , ours show the temporal dynamics of emissions based on actual emissions data from power generation (for 29 countries) and industry (for 73 countries), on near real time activity data for road transportation (for 132 countries ), aviation and maritime transportation , and on heating degree days for commercial and residential sectors emissions (for 206 countries).
After revision:  Unlike other emerging estimates of COVID impacts based on monthly energy supply or estimated parameters, this study contributes to another step that constructed the near-real-time daily CO2 emission inventories based on activity from power generation (for 29 countries) and industry (for 73 countries), on near real time activity data for road transportation (for 132 countries ), aviation and maritime transportation , and on heating degree days for commercial and residential sectors emissions (for 206 countries).
