No but it certainly does mean legislators and regulators should not be totally blinkered to the negative side effects and be very careful and considered with regard to which direction they push people in and what they choose to incentivise by taxation.Jobbo wrote: Fri Feb 07, 2020 1:17 pm The push towards diesel cars was exactly the intended effect. CO2 emissions were reduced.
The fact that another concern has arisen doesn’t mean the push to lower CO2 has unintended effects.
The detrimental effects of particulate matter and NOx were well understood at the time and a better approach would have been not to push people into diesels and just shrug shoulders about the very damaging local pollution emitted - that's not incompatible with incentivising lower CO2 in petrol cars.
Environmentally and from a human perspective they made a terrible mistake in pushing diesel.
