Diesel Carcinogens come from particulate matter which is all but stopped with a particulate filter

 

 

 

Thanks for being a responsible diesel owner. If every diesel owner was like you it would make a massive difference.

Massive gains could be made by simply getting the gross emitters off the road or fixed.

(for example there is a modern BMW 7 series I see sometimes on my way to work, it spews out a cloud of black smoke every time it accelerates (even gently), not something that any moden car should do.)

There are limitations to the effectiveness of the diesel particulate filters and there are a lot of nasty fumes that are not affected by the particulate filter (i.e. NOx).

If diesel emission standards were working, the air quality of european cities should have got better as over recent years as their vehicle fleets got newer(and hence covered by higher emissions standards). The reverse was actually the case. A sad story regarding well meaning policy backfiring...

Regarding wood (and other rubbish / toxic waste burning), this is a bigger issue than car fumes (although dropping as more people move to more convenient methods of heating). How can you stop people from burning things they shouldn't in their fire (other than the obvious of banning fireplaces?)
