European Union emissions trading system support

Helping stakeholders implement the EU ETS scheme for aviation in a fair, equitable and efficient manner.

2019 Draft Annual Emissions Report (AER) CORSIA data now available

The amended report includes aviation emissions data relating to the reduced scope of the EU ETS for the current year. These data are updated on a monthly basis, bringing you the latest available information with each download of the report (late billing or credit for Route Charges, for example).

Compliance with CORSIA regulation - UPDATE

  • Aircraft operators established in the European Economic Area (EEA)

 Our CORSIA dedicated data are now available. To get them, please access your account to download a new report or send us an email via the contact form which you can find at the bottom of this web page. 

  • All other aircraft operators 

We will be making data and reports related to CORSIA available in the weeks to come.

We have set-up a support facility to assist our stakeholders implementing the European Union Emissions Trading System (EU ETS) for aviation.  Beneficiaries include different parties such as the competent authorities in the European Economic Area (EEA) Member States, the European Commission (the regulator) and aircraft operators (the regulated entities) which can, via this service, discharge their obligations under the EU ETS.

The EU ETS SF helps with monitoring and reporting and makes processes go smoothly. It helps both States and users to save money by reducing the cost of compliance with the legislation.

Competent authorities

We provide the CAs with information and data relevant to the EU ETS to support them in complying with their regulatory obligations under the EU ETS. The support facility is available online to EEA States and via our helpdesk.

European Commission

Using our expertise, modelling and database capabilities, we provide the European Commission with:

  • the information which the EC uses for the annual publication of its list associating aircraft operators with EU ETS-administering states;
  • an estimate of the historical aviation emissions for the period 2004-2006, which the EC will take into account when publishing the aviation sector’s emissions cap within the EU ETS;
  • assessments of the possible impact of changes to the legislation.

Aircraft operators

To the benefit of aircraft operators (AOs), we produce a draft Annual Emissions Report (AER) and associated flight data information (Flight Data File).

The draft AER and flight data is sent to aircraft operators (AOs) by email. This information may interest:

  • small and larger aircraft operators in preparing their annual report under the EU ETS;
  • some aircraft operators who can complete and submit it to their competent authorities without third party verification, reducing compliance costs;
  • verifiers mandated to verify an aircraft operator’s annual emissions or tonne-kilometre report;
  • service management companies acting on behalf of aircraft operators;

The Flight Data File includes:

  • all flights attributed to the aircraft operator and operating in the ETS area (both included and exempted flights);
  • details allowing the identification of the flight and the reasons for its inclusion;
  • estimated fuel consumption based on real distance flown, estimated CO2 emissions, possible ETS exemption (as determined by EUROCONTROL) upon which the aircraft operator’s draft annual emissions report is built.
Simplified procedure for aircraft operators

Those AOs, who have to report less than 3,000 tonnes of CO2 or have emitted less than 25,000 tonnes of CO2, benefit from a “simplified procedure” which exempts them from further verification. To obtain the report from the EUROCONTROL ETS/SF,  please provide your administrative information and send it to the competent authority without further verification. The ETS SF now includes all the necessary functions for initiating a submission without verification.

Those AOs, who have performed less than 243 flights per period for three consecutive four-month periods (but emitted > 25,000 tonnes of CO2), are considered a “small emitter” and can use the ETS/SF to obtain a draft of their annual emissions, saving time in monitoring. Validation is still required by the verifier before submission to the competent authority.

AOs, other than a small emitter, can obtain flight and emissions information to assist them in performing checks against their own data. Avoid potential issues by identifying missing flights, spotting differences in the application of exemptions, or even filling data gaps.


We charge an annual fee of 400 EUR for all AOs that are interested in using our tool. This fee is invested back into developing solutions to manage requests and cover costs related to improvements, security and confidentiality. It also contributes to our support staff costs. None of the fee represents a financial benefit for EUROCONTROL.

We perform the maintenance and processing of all flight data information in an ETS Support Facility Data Base as part of our support for the EU ETS Competent Authorities. This activity is therefore not included in the costs associated with the ETS support function for AOs and related third party users.

Additional fees may apply to additional services within the tool.
