Every declared fuel and CO₂ figure behind this site, as one CSV. It is the manufacturers' own declarations to the EU regulator, grouped by model and stated with the spread and the number of vehicles behind each figure. Nothing is modelled and nothing is projected.

What it is not

It is not road-test data and not our measurement. A declared figure is a simulation of one standard route at one payload, made by the manufacturer under Regulation (EU) 2017/2400 and reported under Regulation (EU) 2018/956. It compares vehicles with each other; it is not what one lorry uses on one road.How we know sets out the rest.
