Question to the Department for Transport:
To ask the Secretary of State for Transport, what assessment his Department has made of the potential effect of Gas to Liquid fuels on levels of NOx emissions.
The Department is conducting independent tests on paraffinic diesel, a type of Gas to Liquid fuel (GTL), which industry claims has the potential to reduce nitrogen oxides (NOX) emissions from diesel vehicles. The findings are currently being reviewed and will be published in due course. The results will be used to assess the potential environmental benefits of using paraffinic diesel in road transport. Initial findings show considerable variability depending on the vehicle and how it is used.
