PART 3 U.K. Monitoring, reporting and verification (“MRV”) of aeroplane operator annual CO₂ emissions

CHAPTER 2 U.K. Monitoring of aeroplane operator annual CO₂ emissions

Calculation of CO₂ emissions from aeroplane fuel use U.K.

28.—(1) An aeroplane operator must apply a fuel density value to calculate fuel mass where the amount of fuel uplift is determined in units of volume.

(2) The aeroplane operator must record the fuel density, which may be an actual or a standard value of 0.8 kg per litre, that is used for operational and safety reasons such as in an operational, flight or technical log.

(3) The procedure for informing the use of actual or standard density must be detailed in the Emissions Monitoring Plan along with a reference to the relevant aeroplane operator documentation(1).

(4) An aeroplane operator using a Fuel Use Monitoring Method, as set out in Schedule 2, must determine the CO₂ emissions from international flights using the following equation—

where—

• CO₂ = CO₂ emissions in tonnes(2)[F1 ,]

• M_f = Mass of fuel f used in tonnes[F1 ,] and

• FCF_f = Fuel conversion factor of given fuel f.

(5) The fuel conversion factor referred to in paragraph (4) is equal to—

(a) 3.16 (in kg CO₂/kg fuel) for Jet-A fuel,

(b) 3.10 (in kg CO₂/kg fuel) for AvGas, or

(c) 3.10 (in kg CO₂/kg fuel) for Jet-B fuel.
