Not only will electric cars save CO2, but there will be a massive

Hmm, now I wonder why that is. Could it be the popularity of diesel
engines in cars which were the ecomentalists engine of choice only a
few years ago?

What was it they all chanted? We shouldn't use nasty petrol engines
which give off tiny amounts of particulates and virtually no gases
other than CO2 and water vapour from their catalysed exhaust, no ,
lets use something which belches out buckets of filth even with
filters but outputs ever so slightly less CO2 per km. *sigh*

I see you have completely ignored oxides of Nitrogen, the main pollutant
exceedance problem, certainly where I am (central Cambridge). That it is a
NOx rather than a particulates problem is despite the preponderance of
diesels (mainly buses) in the pollution generation compared to the general
case.
