Question to the Department for Transport:

To ask the Secretary of State for Transport, whether his Department has made an assessment of the effect of the use of AdBlue in road transport on the (a) carbon footprint of AdBlue production and (b) level of carbon dioxide emissions.

The Government is committed to ensuring that the transport sector plays a full part in delivering the emissions reductions needed to meet the Climate Change Act (2008) target for an 80% reduction in greenhouse gas emissions by 2050 compared to 1990 levels.

The Department for Transport has made no assessment of the Carbon Dioxide emissions of Adblue production or use. Officials regularly review the emerging evidence on carbon dioxide emissions and, where found to be material, will adjust forecasts and policy to reflect this.
