Alternative Fuel means fuel or power sources used as a substitute for fossil oil sources in transport. They have the potential to help to decarbonise the transport sector and enhance its Environmental Performance and include:
(c) liquid or gaseous biofuels derived from biomass;
(d) synthetic and paraffinic fuels;
(e) natural gas, including biomethane in gaseous form (compressed natural gas) and liquefied form (liquefied natural gas ( LNG )); and
(f) liquefied petroleum gas.
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:
