The document outlines the objectives and strategies for eco-design and lifecycle assessment (LCA) in the aeronautics sector, notably focusing on technologies that aim to significantly reduce emissions and environmental impacts over the product lifecycle. It details the development of airframe technologies, the selection of innovative materials, and the assessment of various technological options through LCA. Key highlights include targeted reductions in NOx, CO2 emissions, and aircraft noise, as well as examples of green technologies being implemented.
