A lawyer has asked the Supreme Court to order a stop to the import and operation of vehicles running on liquefied petroleum gas (LPG). Petitioning the court, Bharat Mani Gautam said the order is needed because Nepal does not have both emission and safety standards for LPG-run vehicles. Gautam argues that instead of setting standards, the government has subsidised LPG vehicles on the assumption that they are emission-free, whereas experts say studies show that emissions from LPG vehicles are equal to that of petrolengines. The LPG vehicles operating in Nepal use gas cylinders meant for household use and are dangerous in public transport.
