Drafting notes

This definition derives from that in the Alternative Fuel Infrastructure Directive 2014 (2014/94/EU).

The definition captures fuels, even those derived from fossil fuels, that have a lower term greenhouse gas intensity than conventional fossil fuels and that may be used to decarbonise the transport sector in the transition to net zero.

The classification of alternative fuels is a technical area. For more information on EU and UK legislation in this area, see:
