In July 2018 the Department for Transport published the Transport Energy Model1. This was developed to provide an objective assessment of the relative environmental performance of the powertrain technologies and fuel choices for different vehicle types.

This assessment concluded compressed natural gas (CNG) vans are estimated to reduce CO2 tailpipe emissions by between 6-9% compared to diesel and between 22-25% for equivalent petrol models. Tailpipe emissions of Nitrogen Oxides (NOx) are estimated to be approximately equivalent to petrol models.
