A stealth tax, not a 'Green tax', and don't motorists pay for emmissions anyway with fuel duty. Out with Communists!
Tax maybe, but not a stealth tax. This charge has had more newspaper reports, TV spots and internet discussion than you can shake a stick at. Plus unlike most taxes that you pay automatically (VAT, PAYE, Insurance premium tax), this one you actually have to call up and pay by credit card. It's about as stealthy as a herd of elephants.
Got to agree with Porsche though, £25 is just too far. CO2 isn't even a local pollutant. You can argue until you are blue in the face about climate change, but not even Red Ken can say that it causes immediate problems in the location it is emmited. That honour goes to the heavy particualtes and harmful NOx that often aren't related to CO2.
