Quick Summary
From January 1, 2026, EU airlines must pay for every tonne of CO₂ they emit. Free carbon allowances no longer exist for the aviation sector.
Airlines flying within the European Economic Area now buy all their allowances at market rates. Current prices sit between €70 and €100 per tonne. For a mid-sized airline, that means an annual carbon bill of €70–100 million.
A critical review is also approaching. By July 2026, the European Commission must assess whether to extend EU ETS to long-haul international flights. That decision could significantly expand the scope of who pays.

What Changed
Free Allowances Are Gone
For years, airlines received a portion of their carbon allowances at no cost. This was a gradual phase-out that began in 2021.
From January 1, 2026, the phase-out is complete. There are no free allowances left.
Every tonne of CO₂ emitted on a covered route now requires a purchased allowance. Airlines buy these at EU auctions or on the secondary carbon market.
The total number of allowances the aviation sector must surrender between 2026 and 2030 is approximately 330 million.
The July 2026 Scope Review
Right now, EU ETS only covers flights between EEA member states. Long-haul flights — to the US, Asia, the Middle East — are handled under CORSIA, not EU ETS.
The European Commission must complete a formal assessment by July 2026. It will examine whether EU ETS should be extended to cover flights to and from Europe.
If the answer is yes, international carriers operating into EU airports could face EU ETS obligations from 2027.
Non-CO₂ Reporting Expansion from 2027
From January 2027, airlines must also report non-CO₂ climate effects for all EU-departing and arriving flights. This includes contrails and nitrogen oxide emissions.
Currently, this reporting only covers intra-EEA flights. The expansion significantly increases the data burden.
Why Free Allowances Were Eliminated
Free allowances weakened the system. When airlines received free allowances, they had less incentive to reduce emissions. The carbon price signal was diluted.
Aviation cannot relocate. Some industries received free allowances because they could move operations to avoid carbon costs — a risk called “carbon leakage.” Airlines fly fixed routes. This risk does not apply.
The sector is now mature enough. Airlines have operated within the EU ETS since 2012. They have compliance systems in place. The transition period is over.
Revenue generation supports decarbonization. Auctioning all allowances raises billions for EU Member States. IATA argues this money should be reinvested into aviation SAF development — not general government budgets.
Who Is Affected
All Airlines on Intra-EEA Routes: Any airline — EU or non-EU-registered — operating between EEA member states must purchase allowances. This covers all short-haul routes within Europe.
Finance and Treasury Teams Carbon is now a significant cost line. At €80 per tonne, it is comparable in scale to fuel hedging exposure for major European operators.
Sustainability and Compliance Teams: Annual emissions must be monitored, verified by a third party, and reported. Allowances must be surrendered by the annual deadline.
SAF Procurement Officers: SAF reduces CO₂ emissions. Fewer emissions means fewer allowances needed. Every tonne of CO₂ avoided through SAF cuts the carbon bill directly.
Long-Haul Carriers Serving Europe: These carriers are not currently covered by the EU ETS. But the July 2026 review could change that. US, Asian, and Middle Eastern operators should monitor the outcome closely.
Compliance Timeline
| Milestone | Date |
|---|---|
| EU ETS aviation scheme begins | 2012 |
| Free allowance phase-out starts | 2021 |
| Free allowances fully eliminated | January 1, 2026 |
| 2025 emissions surrender deadline | April 30, 2026 |
| Commission scope assessment due | By July 2026 |
| Non-CO₂ reporting expands (all EU flights) | January 1, 2027 |
| CORSIA Phase 2 mandatory start | January 1, 2027 |
Operational Impact
The Carbon Bill Is Now Real. There is no offset through free allowances. Every gram of CO₂ on a covered route has a price attached. Finance teams that had not fully modeled this in their 2026 budgets should do so now.
SAF Is the Best Cost Reduction Tool At €80 per tonne, SAF savings on ETS costs are growing. A carrier using SAF on ETS-covered routes reduces both its emissions and its allowance surrender obligation. The two benefits stack.
The July Review — Two Outcomes
If scope stays intra-EEA only: Long-haul carriers plan on the current basis. No change to international route obligations.
If the scope extends to long-haul, international carriers face EU ETS obligations for EU-departing and arriving flights from 2027. This would be the biggest change to the ETS since the scheme began.
Airlines should model both scenarios before finalizing 2027 budgets.
Non-CO₂ Reporting Requires New Data Systems: Non-CO₂ effects like contrails are harder to measure than CO₂. Airlines need data infrastructure to capture and report these effects for all EU-connected flights by January 2027.
Industry Response
IATA wants EU ETS auction revenues reinvested in SAF development. Currently, most of the money goes to general government budgets. IATA argues this should change.
Transport & Environment supports using the July review to extend scope to all EU-departing flights. It has also called for incentives to reduce contrail formation — one of aviation’s largest non-CO₂ warming effects.
Airlines for Europe (A4E) has raised concerns about competitive distortion. EU carriers bear full ETS costs on European routes. Connecting traffic from non-EU airlines does not face the same burden. A scope extension would address this imbalance.

Action Steps
Airlines, finance teams, and sustainability officers should:
- Confirm 2025 annual emissions are verified and allowances surrendered by April 30, 2026
- Model EU ETS cost exposure for 2027 under both intra-EEA-only and extended-scope scenarios
- Update SAF procurement strategy to quantify ETS cost reduction per tonne of SAF on covered routes
- Engage government affairs teams to monitor the July 2026 Commission assessment and submit any industry views through A4E or national airline associations
- Begin building non-CO₂ data reporting systems before the January 2027 expansion deadline
- Long-haul carriers: prepare a contingency compliance plan in case scope is extended
EU ETS Aviation Free Allowances: FAQs
When did the EU ETS free allowances for aviation end?
January 1, 2026. From this date, airlines must purchase allowances for every tonne of CO₂ emitted on intra-EEA routes.
What is the current EU ETS carbon price?
Approximately €70–100 per tonne of CO₂. Prices fluctuate with the broader EU carbon market.
Which routes are covered by EU ETS right now?
Which routes are covered by EU ETS right now? Intra-EEA routes — flights between EU member states plus Norway, Iceland, and Liechtenstein. Long-haul international routes are managed under CORSIA, not EU ETS.
What is the July 2026 assessment?
What is the July 2026 assessment? The Commission must review whether EU ETS scope should extend to flights arriving at or departing from EU airports. The outcome could bring long-haul international carriers into the EU ETS from 2027.
How does SAF reduce EU ETS costs?
How does SAF reduce EU ETS costs? SAF lowers CO₂ emissions per flight. Lower emissions mean fewer allowances must be purchased and surrendered. At €80 per tonne, each tonne of CO₂ avoided through SAF saves €80 in ETS costs.
Where do EU ETS revenues go?
Where do EU ETS revenues go? To EU Member State governments. IATA argues a larger share should be redirected to aviation SAF development through the EU Innovation Fund.
