Question to the Department for Transport:

To ask the Secretary of State for Transport, what assessment she has made of the potential merits of mandating zero-emission transport refrigeration units for refrigerated transport to replace diesel units.

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. Decisions on the long-term approach towards refrigerated units will be taken in the context of this strategy.
