[font size=3]Carmakers will have to slash the carbon emissions of new cars sold in Europe by a third by 2020, according to leaked European Commission documents seen by the Guardian.

The EC proposals would be legally binding and the document plans for even stricter emissions targets for 2025 and 2030, which could only be met if hybrid or electric vehicles become mainstream.

Greg Archer, of campaign group Transport & Environment, said: "Tighter CO2 standards for cars will be welcomed by drivers across Europe who will save €500 per year at the petrol pump on average if this proposal is adopted."

But car manufacturers warned that tough regulation could harm an industry already struggling with the economic crisis and foreign competition.

1. For reference, that's about 57 miles per US gallon

2. How did you convert CO2 emmissions to mpg ?

Or have I misunderstood something ?

3. There are several options for that conversion web page

Scroll down and select 'starting unit' and 'destination unit'. I should have pasted the link you get with the correct ones chosen:

4. Not sure how they're doing that

Any relationship between those two is loose may just be a guide. Otherwise manufacturers' cars with identical CO2 ratings would provide identical mpg figures : that doesn't happen.

My Jeep Unlimited 2.8 CRD [diesel] is 268 g/Km and the figure for that comes out understated @ c. 28 mpg Imperial.

5. If you assume all the carbon content of the fuel becomes carbon dioxide

(reasonable, for an engine and catalytic converter in good working order), then it's a straight calculation, given the fuel, eg:

Where did you get the 'official' mpg figure for your Jeep? Was it the same scenario as the CO2 emissions test?
