Emissions of the aeronautics manufacturing sector based on global market data, and their potential derivation

The aeronautics sector is regarded as an important contributor to climate change, accounting for around 12 % of CO2 emissions in the transportation sector. Besides emissions from the use-phase, additional impacts come from aircraft manufacturing, the end-of-life and recycling. The complexity of aircraft systems and the lack of public data have prevented analysis of aggregated contributions of the value chain to key environmental problems, although this analysis could provide
valuable insights helping to reduce environmental impacts. Fraunhofer has developed a more complete assessment method to quantify the environmental footprint of industrial areas, such as the aeronautics manufacturing sector. The mapping performed by our partners builds on environmental databases and available market data representing 84 % of aircraft sector sales in 2017.
