# Directive 2003/87/EC of the European Parliament and of the Council of 13 October 2003 establishing a system for greenhouse gas emission allowance trading within the Union and amending Council Directive 96/61/EC (Text with EEA relevance), Division: Monitoring of tonne-kilometre data for the purpose of Articles 3e and 3f

Extent: E+W+S+N.I.

For the purpose of applying for an allocation of allowances in accordance with Article 3e(1) or Article 3f(2), the amount of aviation activity shall be calculated in tonne-kilometres using the following formula:
tonne-kilometres = distance × payload
where:
‘ distance ’ means the great circle distance between the aerodrome of departure and the aerodrome of arrival plus an additional fixed factor of 95 km; and
‘ payload ’ means the total mass of freight, mail and passengers carried.
For the purposes of calculating the payload:
the number of passengers shall be the number of persons on-board excluding crew members,
an aircraft operator may choose to apply either the actual or standard mass for passengers and checked baggage contained in its mass and balance documentation for the relevant flights or a default value of 100 kg for each passenger and his checked baggage.
