Question to the Department for Transport:

To ask the Secretary of State for Transport, what steps she is taking to decarbonise refrigerated transport.

The Department for Transport is working with the Department for Energy Security and Net Zero and Department for Environment, Food and Rural Affairs to develop an Off-Road Machinery Decarbonisation Strategy, the scope of which includes transport refrigeration units (TRUs). This strategy will set out how off-road machinery can further decarbonise while maintaining competitiveness, attracting investment and supporting growth. To support this, we are currently reviewing the findings of a multi-year research project commissioned to ZEMO Partnership into the emissions from diesel-powered auxiliary engines, including from TRUs used on heavy goods vehicles.
