The UK Space Agency’s tenure as Chair has strengthened global coordination in Earth observation (EO) and highlighted the vital role of satellite data in addressing climate change, driving innovation, and inspiring the next generation of scientists. As Chair for 2025, the UK led under the theme “Unlocking EO for Society,” focusing on how satellite data can create real-world benefits, from informing policy to supporting climate action and resilience. By enhancing the contributions of CEOS and the Coordination Group for Meteorological Satellites (CGMS) to the UNFCCC’s Global Stocktake, the UK helped ensure that satellite-derived climate data plays a central role in assessing global progress toward the Paris Agreement.
