Diesel powered auxiliary engines on transport refrigeration units are built to different standards than on-highway engines and for this reason can emit pollution at a higher rate than the main engine. However, quantifying the overall contribution to London's air pollution is complex given that these vehicle types are not clearly distinguishable within traffic statistics or in emissions inventories. Manufacturers are starting to develop innovative technologies that could reduce emissions from these vehicles and TfL will explore the potential for these technologies to be increasingly adopted in London, including as part of the review of the Low Emission Zone and consideration of expanding the Ultra Low Emission Zone.
