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).
SET is a simplified fuel and CO2 estimator, allows aircraft operators (AOs) to estimate their fuel burn on a flight-by-flight basis. It has been developed for, and adopted by, the European Commission. This tool meets the requirements of the guidelines established by Decision 2007/589/EC; its approach is based on individual flights, actual route length and statistically sound fuel consumption relationships. It is, therefore, appropriate for aircraft operators so that they can fulfil their monitoring and reporting obligations in an administratively less burdensome manner.
