The article discusses the importance of tax incentives for using liquefied petroleum gas (LPG) as a cleaner fuel in the UK. If the tax breaks for LPG are not extended, it could lead to a decrease in LPG infrastructure and converted vehicles. This would impact jobs, investments, and the environment. The growth of LPG has caused a loss of income for the government. The article also compares LPG with other alternative fuels like compressed natural gas and liquefied natural gas. The Institute for Public Policy Research suggests reducing the advantage of LPG gradually and supporting a variety of alternative fuels.
