1. Aircraft operators operating fewer than 243 flights per period for three consecutive four-month periods and aircraft operators operating flights with total annual emissions lower than 25 000 tonnes CO₂ per year shall be considered small emitters.

2.By way of derogation from Article 53, small emitters and aircraft operators having total annual emissions lower than 3 000 tonnes of CO₂ from flights other than those referred to in Article 28a(1), point (a), and Article 3c(8) of Directive 2003/87/EC may estimate the fuel consumption based on distance per aerodrome pair using tools implemented by Eurocontrol or another relevant organisation, which can process all relevant air traffic information and avoid any underestimations of emissions.

The applicable tools may only be used if they are approved by the Commission including the application of correction factors to compensate for any inaccuracies in the modelling methods.

3. By way of derogation from Article 12, a small emitter that intends to make use of any of the tools referred to in paragraph 2 of this Article may submit only the following information in the monitoring plan for emissions:
