The Government’s official line for not offering grants on low-emission cars because it will have little impact on the buyer’s purchase decision flies in the face of research.

A survey of 1,200 people by Tickbox.net for the SMMT found nine in 10 motorists would change to a greener car, but 36% expect a Government grant. A Honda survey reveals that 35% of motorists believe the Government is responsible for ensuring people drive cleaner cars.

The Government’s decision, which followed EC approval for the Low Carbon Car Fund that would give buyers of cars with CO2 emissions below 115g/km a grant of between £300 and £1,000, has dismayed the motor industry.

SMMT chief executive Christopher Macgowan, says: “We are stunned. It sends the wrong message to consumers and the industry at a time when Government claims to be taking a lead on lowering CO2 emissions.”
