Speakers
Description
This presentation will provide updates on the last results of the GreenSat study currently performed by Thales Alenia Space in France and Deloitte Sustainability. A Life Cycle Assessment (LCA) of the Sentinel 3 mission has been carried out and the results investigated in order to identify the environmental hotspots of the Sentinel 3 mission. Based on these results, brainstorming sessions have been organized in order to identify potential ecodesign options aiming to reduce the environmental footprint of the Sentinel 3 satellite. The different options have been traded-off against a series of objectives/indicators. The presentation will in particular highlight the challenge of rating different ecodesign options based on multicriteria results (environmental performance, technical performance, customer value, etc.). More generally, the presentation will address the relevance of performing ecodesign at mission level and show the necessity of a broader approach to include the impacts of satellite design on the ground segment and the launch segment.
