Question to the Department for Transport:
To ask the Secretary of State for Transport, what assessment he has made of the effectiveness of LPG vehicles in reducing levels of air pollution.
The environmental performance of LPG in vehicles has been analysed using the Transport Energy Model (TEM), developed by the Department. The model estimates energy consumption and environmental emissions for road transport technology options over the period to 2050, and compares various vehicle powertrain technology and fuel options for cars, vans, buses and HGVs.
The output of this analysis will be included in the zero emission road transport strategy, which is due to be published shortly.
