The lowest CO2 manufacturer is Fiat, who just pipped Mini to retake the Number One spot.
New data shows that CO2 outputs are now falling at their fastest rate since CO2 measurements started in the 1990s.
Figures from www.cleangreencars.co.uk show that in the first half of 2008 the average CO2 output of new cars was 160.5 g/km of CO2, compared to 165.7 g/km of CO2 in the first half of 2007, a 3.2% drop.
"The first six months of the year have seen the biggest drop in new car CO2 outputs on record', said Jay Nagley of Clean Green Cars.
"The great irony is that rising fuel costs, not environmental concerns, have done more to accelerate the shift to more fuel efficient cars than any other initiative. Whether we like it or not, for most people, saving money still trumps saving the planet when it comes to buying a new car."
The lowest CO2 manufacturer was Fiat, who just pipped Mini to retake the Number One spot. OF the major manufacturers, the biggest improvement came from BMW who cut CO2 by 11.3% over the last 12 months.
