Question to the Department for Transport:

To ask Her Majesty's Government what assessment they have made of the impact that banning 38.4 tonne and 44 tonne volumetric concrete mixer vehicles from 2028 will have on CO2 emissions.

A special dispensation was made for volumetric concrete mixers in operation or on order by the end of 2018 to allow them to operate at weights higher than the usual maxima. Articulated vehicles are allowed to operate at maximum laden weights of up to 44 tonnes, depending on their axle configurations.

No specific estimate has been made of the effect on CO2 emissions of requiring operators of volumetric concrete mixers to comply with the standard weight limits applicable to heavy goods vehicles (and other specialised vehicles). A total of 1106 volumetric concrete mixers are currently in circulation in Great Britain operating under Vehicle Special Orders permitting them to operate at higher than usual weights. The Department’s estimate is that these vehicles represent the vast majority of the type in operation.
