Yes, some of the cars are bigger, some may even be fatter (whatever that means) but none of them are more polluting than ever! In fact, even the Hummer is much less polluting than the smallest cars were 20 years ago. This is not an argument of values and principles, this is an argument of measurable science and quantities of emissions. Both emissions and fuel consumption of cars have improved dramatically in the last 30 years.
Peter Foster points this out in the National Post column today.
