Question to the Department for Transport:
To ask the Secretary of State for Transport, what assessment he has made of the effect of commercial fleet vehicles on air quality in (a) Huddersfield and (b) the UK.
Data from the government’s national air quality model indicates that in Huddersfield, emissions from HGVs, LGVs and buses combined contribute, on average, 45% of roadside NOx emissions. This is compared to 55% from cars. For the UK as a whole the average contribution is 48% from HGVs, LGVs and buses, and 51% from cars.
