§ Mrs. Helen ClarkTo ask the Secretary of State for Transport how many tonnes of(a) 1,3-butadiene, (b) benzene, (c) particulates and (d) sulphur dioxide emissions he estimates have been saved as a result of the liquid petroleum gas duty rebate. [151037]
§ Mr. JamiesonIt is not possible to give a precise estimate. Liquefied petroleum gas is a clean fuel which results in very low emissions of a number of key air pollutants. It can have particular benefits, for example, when it is used as a substitute for diesel fuel in polluted urban areas. The nature and scale of the emissions savings, however, will depend on a number of factors, including the type of vehicle and fuel which is being replaced by LPG, and how and where it is being driven.
