The organisation says that a longer-term move to maintain lower fuel duty for LPG Autogas will help to support the UK’s ongoing air quality targets and save public funds by improving air quality in urban locations.

It added that providing equal recognition for LPG Autogas in the fuel duty commitment to 2024 will also deliver significant benefits to the UK economy through VAT paid on vehicle conversions.

“We urge the government to seize its last chance before the General Election to ensure duty parity for all gaseous fuels,” said Rob Shuttleworth, UKLPG’s chief executive.

“LP Autogas emits fewer of the pollutants harmful to human health than diesel, and less carbon than both diesel and petrol. It has a clear role to play in tackling GHG emissions from transport and improving air quality in our cities. Therefore, we urge George Osborne to ensure that all transport fuels have a level playing field.”
