Changes in CO_2 emissions during the COVID-19 pandemic have been estimated from indicators on activities like transportation and electricity generation. Here, we instead use satellite observations together with bottom-up information to track the daily dynamics of CO_2 emissions during the pandemic. Unlike activity data, our observation-based analysis can be independently evaluated and can provide more detailed insights into spatially-explicit changes. Specifically, we use TROPOMI observations

Between January and April 2020, China's CO_2 emissions fell by 11.5 since rebounded to pre-pandemic levels owing to the fast economic recovery in provinces where industrial activity is concentrated.
