The Institue for Public Policy Research (IPPR) has published a report which argues that tax incentives should benefit biofuels instead of LPG.

According to IPPR, the “vast majority of environmentally friendly cars are no less polluting than modern conventional models”.

But Philip Sellwood, chief executive of the Energy Saving Trust, has slammed the report. “IPPR’s report makes interesting reading if we are debating the fuel duties in 20 years’ time, but it does not reflect today’s market realities,” he said. “On a wheel to wheel basis, quality approved LPG vehicles still perform by reducing carbon dioxide in relation to petrol and diesel.”

The LPG Association agrees: “We think the report is inaccurate and totally one-sided and biased,” said spokesman Tom Fidell. “We don’t know the impact this report will have on the government’s consultation at this stage but we hope people will keep open minds and see through it.”
