The European Commission has adopted a Delegated Regulation that sets out detailed rules for monitoring, reporting, and verifying aviation emissions to implement the Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA) within the European Economic Area (EEA). This act ensures that EEA-based aircraft operators comply with international offsetting obligations for emissions from flights outside the scope of the EU Emissions Trading System (ETS) during the periods 2021-2023 and 2024-2026.

Replacing provisional measures from 2019, the new regulation introduces clear procedures for the recognition of certified CORSIA-eligible fuels and the submission of emissions unit cancellation reports. These are critical for calculating offsetting obligations and verifying compliance under both CORSIA and the revised EU ETS Directive.

By aligning with global climate action through the International Civil Aviation Organisation's (ICAO) CORSIA scheme, the updated rules reinforce the EU’s commitment to sustainable aviation and international cooperation in reducing greenhouse gas emissions. The regulation is now subject to a two-month scrutiny period by the European Parliament and Council before entering into force.
