• EU proposes revisions to EU ETS, a carbon pricing scheme.
• EU ETS may apply to flights departing from EEA airports to destinations within 5,000 km.
• Proposal does not extend EU ETS to flights arriving from outside the EEA or departing to destinations beyond 5,000 km.
• EU ETS could be retracted or expanded based on CORSIA's effectiveness in 2032.

The EU's proposal may indicate a shift in its approach to regulating international aviation emissions, potentially undermining CORSIA's status as the sole global market-based measure. This development could have significant implications for the aviation industry, as it may lead to double charging for CO2 emissions and damage the implementation of CORSIA, which suggests a need for closer alignment between EU ETS and CORSIA.
