With much talk about the pros and cons of diesel Vs petrol, low emission zones, extra charges - whether VED or 'congestion' charges, I came across this article on the BBC website.
http://www.bbc.co.uk/news/resources/idt-sh/how_toxic_is_your_car_exhaust
This compares some real world testing of an ageing VW petrol Golf and a Euro 4 Skoda - the discussion which follows is very interesting, with independent real-world tests showing that a new Euro 6 Qashqai N-Connecta DCI CVT is far dirtier than the Euro 4 Skoda (NOx), and that the old petrol is dirtier than the Skoda, but cleaner than the Quahqai!
So what about the Cali's?
Well the real-world independent tester was Emissions Analyticals and they have tested Transporters, including a 2012 California http://equaindex.com/equa-lcv-index/
Their information appears to feed in to another website that provides estimated real-world figures for most vehicles, including California diesel and petrol editions.

For those tempted by the petrol, the figures are not clear cut - yes, less NOx at the tailpipe but more CO2 and at a higher cost per mile with significantly lower MPG.
Worth a read.
