EU ETS Aviation 2026: which aircraft operators must report emissions and what happens if they fail to comply

Key data

If your company operates commercial flights within the European Economic Area — whether as an airline, business aviation operator or company with its own fleet — you need to verify whether you appear on the updated list under Regulation (EU) 2026/784. The regulation entered into force on 26 March 2026 and amends Regulation (EC) 748/2009, which is the official register of operators subject to the European Union Emissions Trading System (EU ETS).

Being unaware of this update does not exempt you from obligations. If your operator has been included, reassigned to another administering Member State, or if there have been relevant corporate changes (mergers, acquisitions), compliance obligations remain active from the date of entry into force.

What does this regulation establish?

Regulation (EU) 2026/784 updates the official list of aircraft operators carrying out aviation activities included in Annex I of Directive 2003/87/EC, which is the framework regulation of the EU ETS. This list determines who is within the system and, therefore, who has compliance obligations.

The changes reflected in this update respond to real movements in the European aviation market:

• New airlines that have commenced commercial operations in the EEA and must be incorporated into the system.
• Mergers and acquisitions that have modified the ownership or structure of existing operators.
• Cessations of activity by operators that no longer carry out flights subject to the ETS.
• Administrative reassignments between Member States, when an operator comes under the supervision of a different country than before.

Each operator included in the list is assigned to a specific administering Member State, which is responsible for overseeing its compliance. This is relevant because it determines which national authority the operator must report to.

Economic and operational impact

The EU ETS has a direct economic cost for included operators: they must acquire or hold sufficient emission allowances to cover their actual emissions. The price of these allowances fluctuates on the European carbon market, making compliance an operational cost variable that must be actively managed.

Beyond the cost of allowances, non-compliance has serious consequences:

• Significant financial penalties, the specific amount of which depends on the applicable regulation in each administering Member State.
• A ban on operating in European airspace, which is the most severe sanction and can completely halt operations.

Reassignments of administering Member State also have an operational impact: the operator must know which national authority to submit its reports to, what deadlines apply and what specific requirements that country imposes regarding emissions verification.

For companies with their own fleets that use business aviation as a business tool, inclusion on the EU ETS list may represent an unexpected cost if it has not been planned for. Monitoring and reporting require internal systems and processes that are not always in place for non-specialised operators.

Who is affected?

• Commercial airlines operating routes within the European Economic Area (intra-European flights).
• Business aviation operators carrying out commercial flights in the EEA, even if they are not conventional passenger airlines.
• Companies with their own fleets that use aircraft for commercial flights within the EEA and may be included in Annex I of Directive 2003/87/EC.
• Operators affected by recent mergers or acquisitions, whose ownership has changed and who must verify whether the reassignment on the list affects them.
• New operators that have commenced commercial aviation activity in Europe and must check whether they have been incorporated into the list.

Practical example

Imagine a Spanish logistics company that operates its own fleet of aircraft for the transport of goods between different EEA countries. Following a merger with another European operator in 2025, the resulting new entity may have been incorporated into the updated list under Regulation (EU) 2026/784, with Spain as the administering Member State.

From 26 March 2026, this company is obliged to:

1. Monitor the CO2 emissions from all its intra-European flights in accordance with its approved monitoring plan.
2. Submit a verified emissions report to the competent Spanish authority.
3. Surrender emission allowances equivalent to its actual emissions for the period.

If the company was unaware of its inclusion on the updated list and has not implemented the necessary monitoring systems, it is exposed to significant financial penalties and, in the worst case, a ban on operating. Verifying the updated list is the mandatory first step.

What should companies do now?

1. Verify whether you appear on the updated list. Consult Regulation (EU) 2026/784 published in the Official Journal of the EU on 31 March 2026 to confirm whether your operator is included or has been reassigned to a new administering Member State.
2. Identify your administering Member State. Each operator is assigned a country responsible for its supervision. Knowing which one determines which authority you must report to and what specific deadlines and requirements apply.
3. Review your emissions monitoring plan. If you have undergone corporate changes (merger, acquisition, name change), verify that the approved monitoring plan remains valid for the new entity.
4. Implement or review reporting systems. Monitoring and surrender of emission allowances obligations require operational internal processes. If you do not have them, implement them urgently as the regulation is already in force.
5. Consult an EU ETS specialist. If there are doubts about whether your operations are subject to the system or about the scope of the obligations, seek specialist advice to avoid penalties and a possible ban on operating.
