How is it implemented?

Clean technologies for space are being defined by ESA as those which contribute to the reduction of the environmental impact of space programmes, taking into account the overall life-cycle and the management of residual waste and pollution resulting from space activities, both in the terrestrial eco-sphere and in space. 

The term clean technologies encompasses both green technologies to mitigate the environmental impacts of space programmes on Earth and space technologies to reduce the impact of ESA missions on the space debris environment (in terms of mitigation and remediation).

Clean Space implementation is organised around four distinct branches:

• Eco-design
• Green technologies
• Space debris mitigation
• Technologies for space debris remediation.
