Session Abstract
While the concept of life cycle thinking and the eco-design approach is attractive for its holistic vision and its promise to reduce the environmental impacts of systems during development and operational phases, how does it translate into reality? The implementation of life cycle thinking in the development processes of space and aerospace systems is essential for informed decision-making, aiming to reduce their environmental impacts and thus contribute to sustainability goals.This session aims to explore the advances, successes, biases, and methodological limits of implementing eco-design in these industrial sectors. The discussion will focus on:
1. The specificities of the aforementioned sectors and their implications in implementing an eco-design approach.
2. The adaptation of methodologies and databases related to eco-design methodologies, particularly Life Cycle Assessment (LCA)
3. The challenges associated with environmental indicators, both classical and specific to these sectors.
4. The selection and development of more environmentally-friendly technologies.
5. The evaluation and handling of rebound effects and/or impact shifting.
