The European Space Agency announced that the instrument for its upcoming carbon dioxide monitoring satellite has successfully passed vacuum testing. This is a key milestone for the Copernicus CO2M mission, which aims to measure atmospheric carbon dioxide from space with high precision. The data will help track emissions sources and sinks globally, supporting climate policy and carbon market verification. Space-based CO2 monitoring is becoming an important tool for verifying national emissions reports and detecting large point sources. The ESA mission is expected to launch in the coming years and will complement existing satellites like NASA's OCO-2. For carbon markets, independent satellite data could improve transparency and trust in emissions claims.
