Supporting LEFT testing

Project Brief

The Low Emission Freight and Logistics Trial (LEFT) involves a wide selection of alternative technologies being assessed both in-service and through a dedicated, laboratory-based emissions testing programme, under a £20 million government programme to cut emissions from road freight and improve air quality.
The aim of the competition is to demonstrate new technologies and to encourage the widespread introduction of low and zero emission vehicles to UK fleets.
The funding is being delivered by the Office for Low Emission Vehicles (OLEV) and Innovate UK. TRL are the lead delivery contractor, carrying out data collection and analysis of the performance, cost savings and environmental impacts of the trial vehicles to evidence impact.
LowCVP’s role is to provide technical guidance and support to TRL, on behalf of Innovate UK, in planning and delivery of the emissions testing programme. This includes test methodologies, instrumentation, test vehicle and diesel Euro VI comparator selection, data processing and results presentation.
The initial priority in 2018 was to update the government’s evidence base on the emissions performance of gas-powered vehicles, to inform the Treasury’s review of fuel duties, with the other technologies scheduled for testing later in 2018 and early in 2019. 


To ensure the laboratory-based emissions testing delivers robust evidence on the likely real-world emissions saving potential of the LEFT technologies over a representative range of duty cycles and conditions.
