In 2020, many countries implemented lockdowns to control the spread of the novel coronavirus disease (COVID-19), leading to reported decreases in anthropogenic CO2 emissions based on bottom-up estimates. Some studies reported that the resulting atmospheric CO2 changes were below the detection limit of current observing systems on the ground or in space. We quantify CO2 emissions from Europe’s largest fossil fuel burning power plant before and during lockdown using space-based CO2 observations from NASA’s Orbiting Carbon Observatory (OCO) 2 and 3 missions. The results show clear emission reductions of >20% in April 2020, demonstrating the ability of space-based CO2 observations to quantify emission reductions at the facility level. This research reinforces the value of space-based CO2 data for verifying future CO2 emission reductions expected from climate change mitigation policies and the importance of monitoring emissions at sub-national scales.
