Strategic Insights -

The European Commission issued a regulation on 24 July 2025, outlining the list of States considered to be applying the Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA) for emissions in 2025. This regulation builds on the amendments made to Directive 2003/87/EC by Directive (EU) 2023/958, which aimed to implement CORSIA and support the aviation industry's contribution to the Union's economy-wide emission reduction target. The regulation provides a list of States that have notified their intention to apply CORSIA for emissions in 2025, as published by the ICAO Secretariat.

Key Takeaways:

  • The regulation aims to implement CORSIA for emissions in 2025, as per Directive 2003/87/EC.
  • The list of States considered to be applying CORSIA for emissions in 2025 is set out in the Annex to the regulation.
  • The regulation excludes EEA countries, Switzerland, and the United Kingdom from the list, as they have their own emissions trading systems.
  • San Marino and Monaco are included in the ICAO Secretariat's list but excluded from the Annex due to lacking airports and flights involving routes to which CORSIA is being applied.
  • The regulation was adopted based on the opinion of the Climate Change Committee and will enter into force on 23 August 2025.
  • The regulation applies to all Member States and is directly binding.
