Record-breaking temperatures in 2023 and 2024, alongside Europe’s faster warming compared to other continents, have made this decade pivotal in combating climate change. The aviation sector finds itself at a crucial juncture in meeting decarbonization goals. Ambitious environmental targets for noise and emission reductions have been set at both European and International Civil Aviation Organization (ICAO) levels.
Significant progress is being made within the framework of the European Green Deal and global environmental policies. The fourth edition of the European Aviation Environmental Report (EAER), prepared with contributions from the European Union Aviation Safety Agency (EASA), the European Commission, the European Environment Agency (EEA), and EUROCONTROL, details the sector’s progress towards sustainability.
Key Highlights of EAER 2025
The EAER 2025 examines the aviation sector’s current progress, challenges, and future strategies for achieving its environmental objectives. Key areas covered include:
Air Traffic and Emissions
A comprehensive review of historical and projected air traffic scenarios and their impact on noise and emissions.
Mitigation Areas
Advancements in technology and design, sustainable aviation fuels (SAF), air traffic management (ATM), operational improvements, airport initiatives, market-based measures, and international collaboration.
Performance Indicators
Development of measurable goals to track the climate and environmental contributions of Single European Sky reforms.
The report also addresses progress in implementing recommendations from the 2022 edition and highlights innovations in sustainable aviation fuels.
Critical Statements from European Leaders
- Apostolos Tzitzikostas, European Commissioner for Sustainable Transport and Tourism:
“Environmental sustainability in aviation is key to supporting the sector’s growth while playing a vital role in combating climate change. The EAER serves as a critical resource for aligning European aviation with EU and international goals.” - Florian Guillermet, EASA Executive Director:
“Swift action is necessary to achieve sustainability targets. This report provides essential guidance for the transition to clean aviation.” - Raúl Medina Caballero, Director General of EUROCONTROL:
“This report underscores the importance of transparency and data-driven approaches to improve environmental performance in aviation.” - Leena Ylä-Mononen, EEA Executive Director:
“European aviation plays a critical role in addressing climate change and pollution. The EAER offers invaluable insights into solutions for these challenges.”
Long-Term Aviation Traffic Projections
Despite ongoing impacts from the COVID-19 pandemic, the total number of flights at EU27+EFTA airports reached 8.35 million in 2023—still 10% below 2019 levels. However, long-term projections suggest that flight numbers could rise to 11.8 million by 2050. Efforts to mitigate the environmental impact of this growth include increasing sustainable fuel use and improving operational efficiencies.
The Importance and Future Impact of the EAER
The EAER stands out as a vital reference for improving the aviation sector’s environmental performance and achieving future targets. By outlining solutions in technology, sustainable fuels, and international collaboration, the report provides a critical roadmap for the sector’s transformation in the years ahead.
