Small Emitters Tool (SET)

The Small Emitters Tool (SET) makes it possible to estimate the fuel burn for an entire flight considering the characteristics of the air traffic covered by the EU Emissions Trading Scheme (EU ETS). The SET has been validated by the European Commission tool supporting the Emissions Trading Scheme.

The SET cannot estimate CO2 emissions for specific phases of the flight (landing or cruise) or other emissions (NOX, etc.). Other EUROCONTROL tools can be used for that purpose, such as AEM (Advanced Emission Model).

The SET is updated on a regular basis in order to make it as accurate as possible. Different versions of the tool are available depending on the year the flight was operated.


Versions of the tool available for download

For 2014 flights

Version 5.03 (released on 24.11.14)

It includes five new aircraft types (incl. A359 as they were flown in 2014 in the European Economic Area (EEA) region.

Ten existing aircraft types for business jets have also been calibrated. These ten types are now modelled on the basis of actual fuel-burn samples from real life operations that have been collected from aircraft operators (AOs).

For 2013 flights 

Version 5.02 (released on 1.8.13)

It includes the GLF6 and EC75 aircraft types and the calibration of former existing types, using 2010 and 2011 actual fuel-burn data collected from aircraft operators (AOs).

It is very important that aircraft operators (AOs), as small emitters (for their simplified monitoring procedure and reporting) or regular operators (when reporting data gaps) use only the relevant version for each reporting period.

This requirement is the only way to ensure a smooth processing of AOs' reported data by   your verifiers (if any) but also by your administering States.

How we help

We, at EUROCONTROL, introduced the SET as a solution to meeting the requirements of the guidelines established by Decision 2007/589/EC in respect of the approach based on:

  • individual flights and aircraft type used (as per ICAO doc 8643);
  • actual route length; and
  • statistically sound fuel-consumption relationships.

According to European Commission Decision 2007/589/EC, amended by Decision 2009/339/EC, a simplified method for EU ETS monitoring and reporting purposes can be used to determine fuel consumption and carbon-dioxide emissions.

The SET is an algorithm in essence that is available in a standalone version (in Excel format for manual entry and usage) but it is also a part of the code within the ETS Support Facility, a comprehensive integrated solution with individual flight database records designed for ETS follow-up and compliance to support aircraft operators, verifiers, service companies acting on behalf of aircraft operators, and ETS competent authorities.


Who we can help

The following tool versions can be used by:

  • aircraft operators that are “small emitters” (see definition in EC regulations related to ETS), with regard to their monitoring and reporting obligations pursuant to Article 14(3) of Directive 2003/87/EC (the EU ETS Directive) and Part 4 of Annex XIV to Decision 2007/589/EC (the monitoring and reporting guidance);
  • all aircraft operators pursuant to Part 5 of Annex XIV to Decision 2007/589/EC for the purposes of estimating the fuel consumption of particular flights covered by the EU ETS, where the data necessary to monitor the emissions of carbon dioxide are missing as a result of circumstances beyond the control of the aircraft operator and which cannot be determined by an alternative method defined in the operator’s monitoring plan (data gaps).
