Small emitters tool

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


The small emitters tool is the EUROCONTROL meets 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.

The tool is based on a methodology designed to estimate the fuel burn for an entire flight (not for specific flight phases) considering the characteristics of the air traffic covered by the EU ETS. It is updated on a regular basis in order to improve when possible its accuracy.

The following tool versions can be used by :

  • small emitters of their monitoring and reporting obligations pursuant to Article 14(3) of the 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.

Different versions of the tool are available for different years. To ensure consistency with processes of Verifiers and Administering States it is very important that Aircraft Operators, Small Emitters (for their simplified monitoring procedure and reporting) and other Operators (when reporting Data Gaps) use exclusively the relevant version for the each reporting period.

For 2014 traffic emissions version 5.03 dated 2014.11.24, to be used for flights operated in 2014 5 new aircraft types (inc. A359) have been added as these types have been flown in 2014 in the EEA region. The calibration of 10 existing aircraft types for business jets has been made. These 10 types are now modelled on the basis of actual fuel burn samples from real life operations that have collected from Aircraft Operators.
For 2013 traffic emissions  version 5.02 dated 2013.08.01, to be used for flights operated in 2013  Changes are the addition of GLF6 and EC75 new aircraft types and the calibration of former existing types.using 2010 and 2011 actual fuel burn data collected from Aircraft Operators.

The small emitters tool and the ETS Support Facility

The small emitters tool is a part of the ETS Support Facility (read more about it on the ETS Support Facility page).  The ETS Support Facility is a comprehensive integrated solution with individual flights 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.
