- The conceptualization of the Outer Space Footprint (OSF) will help to better take into consideration the environmental impact of space activities. The OSF includes the GHG footprint but is not limited to it (it also include light pollution, land and ocean pollution, and outer space pollution). Thus, by promoting a sustainable development of space activities, C4H directly advocates for the decarbonization of the space sector. 

- By objectively evaluating the behaviour of operators, the OSF will enable consumers of satellite data, citizens and companies, to focus on environmentally responsible operators and to highlight operators committed to a regenerative approach. 

- Preserving access to outer space in an environmentally and economically sustainable manner allows us to maintain satellite capacities, which are an essential tool in the fight against climate change. Beyond the well-known uses, it is important to note from the point of view of our ReFi community that dMRV solutions, which are indispensable tools to encourage local environmental protection initiatives, are backed by satellite imaging capabilities.
