In this interview, Stephen Arrowsmith, Chief Expert on Environmental Protection at EASA, discusses the aviation sector’s efforts to mitigate its climate impact, including non-CO2 emissions, as part of Europe’s goal to achieve net-zero emissions by 2050. He highlights the challenges in addressing non-CO2 emissions, such as gaps in scientific understanding, trade-offs between CO2 and non-CO2 impacts, and the need for accurate modeling of emissions from different fuels and technologies. Arrowsmith emphasizes the importance of coordinated research and decision-making to develop effective strategies that balance environmental benefits with operational feasibility. He also notes that ongoing initiatives, such as ICAO engine certification standards and the adoption of Sustainable Aviation Fuels (SAFs) under the ReFuelEU Aviation Regulation, are already contributing to emission reductions.
Arrowsmith introduces the Aviation Non-CO₂ Experts Network (ANCEN), launched in June 2024 by EASA and the European Commission to unify European research efforts on non-CO2 emissions. ANCEN aims to provide objective technical advice for developing policies and operational measures that address both CO2 and non-CO2 impacts. Its work includes establishing common terminology, assessing uncertainties in climate impact modeling, optimizing aviation research priorities, and fostering global collaboration with partners like ICAO. Looking forward, Arrowsmith stresses that achieving sustainability requires a comprehensive approach involving new technologies, efficient operations, SAFs, and market-based measures. The upcoming 2025 EASA European Aviation Environmental Report will provide further insights into the progress made and next steps for the industry.
