The European Union faces a pivotal EU Emissions Trading System (ETS) revision in July 2026, offering a chance to balance aviation decarbonization with industry competitiveness. Currently limited to intra-European Economic Area (EEA) flights, the ETS covers 64 million tonnes of CO₂ annually, leaving long-haul and many private jet emissions unregulated.
Extending the scope to all departing EU flights would add 80 million tonnes of CO₂, boosting revenues from €3 billion in 2024 to an extra €7 billion. These funds could accelerate sustainable aviation fuel (SAF) uptake and contrail avoidance, potentially cutting 20-40 million tonnes of CO₂ equivalent yearly. Germany, Poland, and Italy stand to gain most from reinvested revenues. Private jets, currently exempting 67% of emissions via de minimis thresholds, require full inclusion.
Free allowances phase out completely by 2026, shifting carbon from an ESG metric to a direct operating cost tied to EU Allowance prices. This impacts route planning, leasing, and aircraft valuation. Airlines must surrender allowances per tonne emitted on intra-EEA flights, achieving over 99.5% compliance historically.
The Commission will assess CORSIA’s Paris Agreement alignment in 2026. If insufficient, especially post-ICAO’s 2025 assembly, ETS expansion to departing flights could replace it, honoring 2008 Parliament and Council approvals for full scope. From 2027, reporting extends to non-CO₂ effects on all Europe-bound flights, enhancing data for policy. Innovation Fund additions support electrification and decarbonization, while aviation pushes for SAF incentives amid regulatory pressures.
