Non-CO2 Emissions from Aviation

Working together towards sustainable aviation, the Aerospace and Defence Industries Association of Europe (ASD) outlines recommendations and initiatives to address non-CO2 emissions from the industry.

Comprising over 4,000 companies, including aircraft and engine manufacturers, ASD is committed to achieving a net-zero CO2 emissions aviation ecosystem in Europe by 2050. The focus of the Destination 2050 route to net-zero European aviation is on reducing CO2 emissions. However, ASD also emphasises the importance of addressing non-CO2 emissions, acknowledging their contribution to global warming. These emissions, including nitrogen oxides, water vapor, and particulate matter, have varying impacts on climate, necessitating thorough research and understanding.

ASD members actively engage in scientific work to understand non-CO2 emissions, supporting projects that examine contrail-cirrus effects, NOx emissions, and environmental trade-offs. The industry is working together on practical solutions, involving fuel composition, engine technology, and flight operations.

To mitigate non-CO2 emissions, ASD advocates for research-driven approaches. In terms of fuel, the industry explores alternatives with lower aromatic and sulphur content, aiming for 100% Sustainable Aviation Fuel (SAF) compatibility by 2030. Engine technology advancements adhere to international standards, with a focus on reducing NOx and particulate matter emissions.

ASD envisions a future with hybrid electric and hydrogen-powered aircraft by 2035, targeting short-range intra-European routes. Eco-friendly flight operations and the Single European Sky ATM Research (SESAR) initiative play pivotal roles in reducing both CO2 and non-CO2 effects.

In conclusion, ASD reaffirms its commitment to impactful solutions for addressing aviation non-CO2 emissions. The industry's dedication reflects a holistic approach to balancing environmental concerns with the practicalities of aviation safety and efficiency.
