Subnational statistics are produced as part of the National Atmospheric Emissions Inventory (NAEI) work programme on fuel consumption from road transport at regional and local authority levels. This is calculated using a bottom-up method by combining fleet-weighted fuel consumption factors (in g fuel/km) for each main vehicle type with traffic activity data provided by the Department for Transport (DfT). The bottom-up calculated fuel consumption derived for each year is expected to vary slightly from the values of petrol and diesel fuel sales reported in the Digest of UK Energy Statistics (DUKES) due to a number of reasons. For instance, the fuel sales figures in DUKES include the small amount of fuel consumption by inland waterways, off-road machinery and consumption in the Crown Dependencies, and thus these values do not represent fuel use by road transport alone; other reasons include "fuel tourism" effects whereby vehicles consume fuel on UK roads that was purchased abroad and modelling uncertainty.
The data is available for download from the BEIS website.
