Eurocontrol Seeks Accurate Data for ETS Emissions Calculations

 - July 31, 2011, 6:15 AM

Eurocontrol is trying to improve the accuracy of the ETS Support Facility, which is intended to give so-called small emitters a relatively easy way to calculate carbon dioxide emissions for the purposes of compliance with the European Union’s controversial emissions trading scheme. It has given operators until September 1 to provide updated fuel-burn data for a large number of aircraft for which the ETS Support Facility currently has inaccurate performance data.

According to the European air traffic management agency, it holds inaccurate data for as many as 265 aircraft types weighing more than 5.7 metric tons (12,566 pounds)–the weight threshold at which ETS starts to apply. These include 17 business jet types (see box).

The European Business Aviation Association is urging operators to cooperate fully with Eurocontrol’s request for information so as to make the ETS Support Facility more viable ( Data needs to be sent to by September 1. The submissions must include the following information (preferably in a Microsoft Excel file): the aircraft identification as specified in field seven of the flight plan filed for each flight made into EU airspace (aircraft registration number or ICAO code), four-letter ICAO designator for departure and destination airports, ICAO aircraft type designator, total fuel burn gate-to-gate (block consumption), total APU fuel burn (if applicable), off-blocks date and time and on-blocks date and time.

In the long-term, Eurocontrol has offered to update aircraft fuel burn data regularly for all types based on actual operational information. In the short term it is prioritizing corrections for types that are not currently “optimally modeled.” Early users of the ETS Support Facility, also referred to as the Small Emitters Tool, have identified substantial discrepancies in fuel burn data for some types.
