Which car is more polluting..
Discussion
Chatting to a friend earlier, I was ribbing him that he'd be getting rid of his 05 Volvo xc90 under the forthcoming diesel scrappage scheme. He said I couldn't really get on my high horse about pollution whilst driving my '90 Porsche 944 s2. Just mindless banter as neither of us knew which is the more polluting vehicle.
I get the impression we're going to becoming much more focused on emissions and pollution in the coming years which is a good thing of course. I've been thinking since, just how polluting are the cars I drive. Is there anyway of comparing diesel and petrol when it comes to actual air pollution? I have to admit I just pay the road fund licence by direct on both our cars. The other is a petrol 03 golf estate 1.8turbo. Neither of my cars are new or frugal on fuel. But my thoughts are they're cleaner than an old xc90 Volvo. Am I right or wrong?

The petrol will put out more CO2 and the Diesel will put out more NOX.
I run in the early mornings when the white vans are starting to move around, and I can tell when one drives by, the diesel fumes hang in the air down the street and it tends to irritate my throat a bit. Petrol cars do not seem to have any nasty irritants like that.

I am of the view that the least polluting car is one that you buy that would otherwise have gone to the scrapper. The bulk of the environmental cost has already been spent - manufacturing.
And in that respect the Volvo has a massive advantage as the Volvo factories get all their power from hydroelectricity :-)If your porka has no catalyst, and hence runs lean on cruise, its tail pipe emissions will be horrible, both in terms of Hydrocarbons on a cold start, and it's NOx emissions on a warm cruise. Something like 30 to 100 times more than the volvo's emissions. Both cars probably do low 30's in terms of mpg, so little to choose from a CO2 perspective

its not polluting, its what Daysul is splurting into the atmosphere.I get the impression we're going to becoming much more focused on emissions and pollution in the coming years which is a good thing of course.

NOX particles, which petrol does not have.
both cars 'pollute' emissions but I would rather a smooth and high revving petrol over a agricultural daysul anytime.
I remember a few years ago i had a Lexus is250, it was amazing as I previosly had mondeo's and Accord's. The almost silent nature and comfort was a joy to behold
anyway, once I got out of the car to be startled by a daysul car craking up in a car park about 15 or 20 feet away.. Such was the refinement i was used to it was shocking to hear this. And I am not talking of cars 20 years old, even relatively new daysul cars sound dreadful.

Once sufficient numbers of people have been fooled into going electric, a report by experts will be produced which shows as if by surprise, that the pollution generated by the batteries in their production, transportation and eventual disposal, is a very bad thing and taxes will be raised.

I read an excellent piece on the horse in the nineteenth century and how the great cities of the world were grinding to a halt, to put it bluntly; under a pile of horse s
t (and dead and dying horses in the streets). Not particularly pleasant, so the advent of the motor car was seen as an environmental saviour. Move on till now and yes, the same is true regarding alternative fuels, and yes, a few years down the line we'll realise we still haven't solved the problem. Only dabbled with the symptoms.
