The Society of Motor Manufacturers and Traders (SMMT) has said nearly 372,401 new vehicles have been registered through the scrappage scheme by the end of March.
The joint Government and motor industry incentive scheme which started in May 2009, saw motorists awarded a £2,000 discount on new cars if they traded in their less green 10-year-old cars.
The SMMT said that new cars registered through the scheme have an average CO2 value of 132.9g/km - 9.6 per cent lower than the 147.0g/km average for all new cars registered between May 2009 and March 2010, and 27.1 per cent below the average CO2 of the scrapped car.
SMMT chief executive Paul Everitt said: "The scheme has provided a hugely important stimulus to the market and leaves industry in far better health than we saw in pre-scrappage 2009."
Motorists out on the road in the UK need to have some form of insurance policy to cover them in the event of a car accident. It is an offence to be driving a vehicle without insurance.
