The 2nd Conference on Earth-Space Sustainability, co-organized by the International Institute of Air and Space Law, the European Research Council (ERC) PlanetStewards Project (Grant Agreement No. 101117483), the Secure World Foundation, and the COST Action FOGOS (CA 23118), was held at Leiden University’s Academy Building.

The conference focused on the intertwined futures of Earth and outer space and what emerged was a collective call to move beyond the siloes that have long separated diverse disciplines in their approaches to sustainability governance: to treat Earth-Space as a single, integrated system demanding integrated responses to fragmented issues.
