Before revision:  Here we show that the decrease in global fossil CO2 emissions during the first quarter of 2020 was of 5.8\% (542 Mt CO2 with a 20\% 1- {\sigma} uncertainty) . 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).
