Clean Green Cars finds a tiny bit of improvement in UK market

When Clean Green Cars took a look at the sales-weighted CO₂ averages of UK vehicle sales, they found a little something to smile about. Or breathe cleaner about, I guess. During the first quarter of 2008, overall average emissions were down 2.79 percent (from 165.75 grams per km average to 161.13). This is a bigger improvement than what happened between the same time frame a year earlier (then, there was only a 1.23 percent improvement). Of course, 160+ is still a lot when you think about the sub-120 targets coming in 2012. As Clean Green Cars points out, the rate of improvement will need to double once again (to 5.3 percent a year) in order to reach that goal.
When we break down the improvements by manufacturer, we find that MINI is currently winning the low CO₂ fight in the UK.

Manufacturer	2007 Q1	2008 Q1	improvement
Mini	155.63	138.87	10.77%
Fiat	141.29	139.64	1.17%
Peugeot	147.59	141.28	4.28%
Citroen	147.97	145.79	1.47%
Toyota	149.38	146.41	1.99%
