Scientists call for action to address air pollution from space launches
Satellite mega-constellation missions behind threefold increase in emissions of climate-altering soot and CO2

Scientists are calling for a new global regime to address air pollution caused by the space industry.
Prof Eloise Marais’s team at University College London (UCL) began trackingspace activities in 2020. Their latest figures reveal 259 rocket launches in 2024, and 223 launches in 2023. These burned more than 153,000 tonnes of fuel.
Marais said: “More pollutants are being released into the atmosphere from rockets and satellites than ever before. We’re in uncharted territory, as humans have never added this much pollution to the upper layers of the atmosphere. If left unregulated, it may have serious impacts on Earth’s atmosphere.”
The team found that launches of mega-constellation communication satellites, including Starlink, OneWeb and Thousand Sails, have led to a threefold increase in emissions of climate-altering soot and carbon dioxide.
