In the past, TfL provided an incentive to users of vehicles fuelled by Liquid Petroleum Gas (LPG) through the Congestion Charging Alternative Fuel Discount.

Whilst there were air quality benefits for earlier cars and vans running on LPG (typically Euro 3 or earlier), the sophisticated integration of vehicle systems and requirements for on-board diagnostics on recent vehicles (Euro 4 onwards), mean that there is no air quality benefit on modern vehicles. CO2 benefits are also negligible when applied to modern vehicles. As a result, TfL has moved away from providing discounts for specific technologies and instead focuses on exhaust emissions. The current Ultra-Low Emission Discount is available for any vehicle which emits less than 100g CO2 per km and meets the Euro 5 emission standard.
