Average new car CO2 figure down 4.7% in first half of 2010 to 145.2g/km, compared with the same period in 2009.

Registrations of alternatively fuelled cars doubled over this period.

Some concern that rate of improvement may slow, but new technologies constantly emerging.

"Continued vehicle manufacturer efforts to improve fuel efficiency and cut emissions has further reduced average CO2 output during a better than anticipated first half of 2010," said Paul Everitt, SMMT chief executive. "The remainder of the year is set to be challenging, especially post the scrappage scheme. All manufacturers are committed to offering ever more efficient products through the introduction of increasingly efficient engines and alternative technologies."
