A survey by the Society of Motor Manufacturers and Traders (SMMT) suggests that 76% of car buyers are in favour of the UK Government introducing a scrappage-incentive scheme.
The scheme would entitle owners of cars over nine years old to claim up to 2000 towards a new or nearly new car if they scrapped their existing vehicle.
Similar schemes are already in place across Europe.
According to SMMT figures, the average new car emits 14.6% less CO2 than a nine-year-old model, so the scheme would reduce emissions, while also boosting UK car sales.
SMMT chief executive Paul Everitt said: 'The scrappage-incentive scheme is a popular way for the Government to support the car industry and provides good value for the taxpayer.
'The positive impact it could have on building consumer confidence and boosting the new vehicle market is extremely valuable to the UK car sector and the 800,000 people that work within it.'
