Tracking CO2 emission reductions from space: A case study at Europe’s largest fossil fuel power plant

We quantify CO 2 emissions from Europe’s largest fossil fuel power plant, the Be?chat?w Power Station in Poland, using observations NASA’s Orbiting Carbon Observatory (OCO) and 3 missions on 10 occasions March 2017 to June 2022. The space-based emission estimates reveal changes with a trend that is consistent independent reported hourly generation results both permanent temporary unit shutdowns. OCO-2 OCO-3 agree bottom-up within their respective 1 ? uncertainties for 9 of occasions. Different methods defining background values corresponding are explored order better understand this important potential error contribution. These demonstrate ability existing reductions large facility when adequate coverage revisits available. informative understanding expected capability limitations planned Copernicus Anthropogenic Monitoring (CO2M) other future satellites support monitoring verification resulting climate change mitigation efforts such as Paris Agreement.
