EU plans to extend carbon emission charges to foreign flights, risking global backlash

The European Commission is eyeing a massive expansion of its emissions trading system to cover all departing flights, a move that could reshape airline economics and carbon markets alike.

The European Union is preparing to do something it tried once before, and got its hand slapped for. The European Commission plans to extend its Emissions Trading System to cover flights departing EU airports for international destinations, not just the intra-European routes currently subject to carbon pricing.

What the EU is actually proposing

Right now, the EU ETS only applies to flights within the European Economic Area. Think Paris to Berlin, not Paris to New York. The proposed expansion would capture emissions from all outgoing flights, which account for a significant majority of aviation emissions tied to EU airports.

A formal assessment is scheduled for July 2026, at which point the Commission will evaluate whether CORSIA, the International Civil Aviation Organization’s carbon offsetting scheme, is doing enough to justify keeping international flights outside the EU’s pricing regime. Legislative proposals could follow, with expanded coverage potentially taking effect by 2027.

The EU has already been tightening the screws on aviation emissions through its Fit for 55 climate package. Free carbon allowances for airlines have been shrinking: a 25% reduction in 2024, 50% in 2025, with full auctioning expected by 2026.

The scale of what’s at stake is significant. Flights from European airports emitted approximately 195 million tons of CO2 in 2025, surpassing pre-pandemic levels from 2019. The ETS expansion could bring an additional roughly 107 million tons of CO2 annually under the pricing umbrella, generating substantial revenue at current allowance prices ranging between 70 and 100 euros per tonne.

The 2012 precedent is not encouraging

In 2012, the Commission attempted to include all international flights in the ETS. The response was swift and hostile. China threatened to block Airbus orders. The US passed legislation prohibiting its airlines from complying. India and Russia joined the opposition chorus. The international flight provisions were suspended, and the ETS was scaled back to cover only intra-EEA routes.

The current proposal would likely exempt incoming flights while capturing emissions from all departing ones. Airline executives are already signaling their displeasure, with the core concern being that carbon pricing increases operational costs, which get passed to passengers through higher ticket prices.

Environmental advocates, including organizations like Transport & Environment, argue that comprehensive emissions pricing is not just appropriate but overdue, and call for a full expansion of the ETS to all departing flights by 2027 to align with the polluter-pays principle. The revenue stream it creates is essential for financing the transition to sustainable aviation fuels and other clean energy technologies.

What this means for investors and carbon markets

For EU-based airlines, full auctioning of allowances by 2026 means emissions become a direct line-item cost. If the ETS then expands to cover international departures, the cost base grows further. Higher ticket prices could dampen leisure travel, which tends to be more price-sensitive than business travel. Cargo shipping rates could also be affected.

For carbon market participants, adding roughly 107 million tons of annual emissions to the ETS pool means significantly more demand for carbon allowances. If supply doesn’t expand proportionally, allowance prices could push toward the upper end of the 70-100 euro per tonne range or beyond.

The geopolitical risk remains the outstanding variable from 2012: unilateral climate measures affecting international aviation invited retaliation from China, the US, India, and Russia. The EU is betting that CORSIA’s limitations are now more widely acknowledged and that the pushback will be more manageable this time.
