Question to the Department for Environment, Food and Rural Affairs:

To ask the Secretary of State for Environment, Food and Rural Affairs, pursuant to the Answer of 4 November 2020 to Question 109136 on Transport: Refrigeration, who his Department has commissioned to conduct research on improving the evidence base on emissions from non-road mobile machinery emissions, including transport refrigeration units; what the (a) timeframe and (b) terms of reference is for that research; and if he will make a statemen.

In the Clean Air Strategy 2019, we committed to exploring further action to tackle non-road mobile machinery (NRMM) emissions in England. In September 2019, Defra commissioned Ricardo Energy & Environment to conduct research to improve the evidence base on emissions from NRMM, including transport refrigeration units, and inform policy development.

Over the next few months, we will be engaging with stakeholders to discuss initial findings of the research. This exercise will help to ensure that we have a robust and accurate evidence base from which to consider policy options.
