Paragraph 27 F1

Article 54 is to be read as if for the whole Article there were substituted—

“Article 54

Specific provisions for biofuels

1.

For mixed fuels, the aircraft operator may either assume the absence of biomass and apply a default fossil fraction of 100% or determine a biomass fraction in accordance with paragraph 2 or 3.

2.

Where biofuels are physically mixed with fossil fuels and delivered to an aircraft in physically identifiable batches, the aircraft operator may carry out analyses in accordance with Articles 32 to 35 to determine the biomass fraction on the basis of a relevant standard and the analytical methods set out in those Articles, provided that the use of that standard and those analytical methods is approved by the regulator. Where the aircraft operator provides evidence to the satisfaction of the regulator that such analyses would incur unreasonable costs or are technically not feasible, the aircraft operator may base an estimation of the biomass fraction on a mass balance of fossil fuels and biofuels purchased.

3.

Where purchased biofuel batches are not physically delivered to a specific aircraft, the aircraft operator shall not use analyses to determine the biomass fraction of the fuels used. In such a case, the aircraft operator may determine the biomass fraction using purchase records of biofuel of equivalent energy content, provided that the aircraft operator provides evidence to the satisfaction of the regulator that there is no double counting of the same biofuel quantity, in particular that the biofuel purchased is not claimed to be used by anyone else.

4.

Where a biofuel meets the sustainability criteria F2..., the emission factor of the biofuel shall be zero; and for the purpose of determining whether the sustainability criteria are met, the biofuel (wherever supplied) must be treated as supplied in the United Kingdom.

5.

Where a biofuel does not meet F3the sustainability criteria, the carbon content of the biofuel shall be treated as fossil carbon.

F46.

In this Article, “sustainability criteria”, in relation to biofuel, means the sustainability criteria (within the meaning of the Renewable Transport Fuel Obligations Order 2007) that applied for the purposes of that Order on the date of purchase of the biofuel.”.
