In late 2025 or 2026, the EU plans to introduce its CO2M (Copernicus Anthropogenic CO2 Monitoring Mission) pair of satellites, whose task will be to assist with this.
Important proof-of-principle for CO2M
But now, researchers have actually shown that such tracking-at-the-source is currently possible, even with existing satellites, for super-emitters like the Belchatów power plant in Poland. For this proof-of-principle, they used 5 years of measurements from NASAs satellite Orbiting Carbon Observatory 2 (OCO-2; released in 2014) and the instrument OCO-3, attached given that 2019 to the International Space Station (ISS).
This success is an important achievement, as the OCO objectives were developed to determine carbon emissions at much bigger spatial scales.
” Here we reveal for the very first time that its already possible to determine modifications in CO2 emissions from a large power plant, with observations from existing CO2-tracking satellites,” said Dr. Ray Nassar, a climatic scientist at Environment and Climate Change Canada, Toronto. He is the research studys first author, released in the journal Frontiers in Remote Sensing.
Biggest power plant in Europe
The Belchatów lignite-fired (brown coal) power plant is the biggest thermal power station in Europe and the fifth biggest on the planet. Here, systems are in some cases decommissioned and new ones put in service, while regularly, systems shut down momentarily for upkeep. To be of usage, satellites and instruments like OCO-2 and OCO-3 must instantly find changes in CO2 emissions due to these changes in operation– and here, Nassar and associates show for the very first time that they can.
CO2 is produced by the 300-meter-high (1000-foot-high) stacks at Belchatów and brought by the wind in the type of an invisible plume, roughly 10-50 km (6-31 mile) long and 550 meters (1800 feet) above Earth. OCO-2, which orbits the Earth at an altitude of 705 km (438 miles), passes every 16 days close by or directly over Belchatów. OCO-3 orbits at an elevation of 420 km and passes over or near Belchatów more often. OCO-3 has the added ability to scan backward and forward across an area, providing much better local protection or a broader view.
Not every flyby or overpass appropriates
Satellites can examine the CO2 improvement– extra CO2 emitted by a source– just in the lack of clouds and when the plume doesnt pass over big water bodies or mountains. They determine XCO2, the average CO2 concentration across a column straight below, subtracting the existing background value (locally, on typical 415 ppm) around the plume.
Together, OCO-2 and OCO-3 yielded 10 appropriate datasets about the CO2 plume above Belchatów between 2017 and 2022.
Exceptional contract between observed and anticipated information
The scientists compared the measurements from space to estimates for Belchatóws emissions, based on its known day-to-day power generation output. OCO-2 detected a short-term however noticable dip in emissions from Belchatów in between June and September 2021, due to shutdowns for maintenance.
All clear for CO2M
The results are promising: they show that CO2M, with a joint spatial protection about a hundred times higher than OCO-2 and OCO-3, will be able to provide on future requirements.
” The capacity to get the most precise details about CO2 emissions from super-emitters, such as the Belchatów power plant, throughout the globe will improve openness in carbon accounting and hopefully, it will eventually help to minimize these emissions,” said Nassar.
” This future capacity will cause improved CO2 emission details at the scale of countries, cities or individual facilities, improving transparency under the Paris Agreement and supporting efforts to reduce emissions triggering climate change.”

Capacity to monitor emissions to increase a hundredfold in the next 3 years.
Countries that registered to the 2015 Paris Agreement have actually committed themselves to keep the rise in typical worldwide temperature well below 2 ° C. Every five years, they are to provide so-called nationally figured out contributions (NDCs), explaining their actions to lower greenhouse gas (GHG) emissions and adapt to climate change effects.
Therefore, countries will require to track their carbon emissions, not just at a national level, but likewise at the scale of private super-emitters such as power plants, megacities, refineries, and huge factories. These super-emitters are together responsible for nearly half of humankinds overall output of GHGs.
To be of use, satellites and instruments like OCO-2 and OCO-3 ought to instantly discover changes in CO2 emissions due to these changes in operation– and here, Nassar and colleagues reveal for the very first time that they can.
CO2 is released by the 300-meter-high (1000-foot-high) stacks at Belchatów and brought by the wind in the form of an undetectable plume, roughly 10-50 km (6-31 mile) long and 550 meters (1800 feet) above Earth. The researchers compared the measurements from space to estimates for Belchatóws emissions, based on its known everyday power generation output. This proves that even today, existing satellites can track emissions in close-to-real time for setups like Belchatów. OCO-2 identified a short-term but noticable dip in emissions from Belchatów in between June and September 2021, due to shutdowns for maintenance.
