I'd have to say yes Bernie. If you are going to tax pollution, then you have to tax how much fuel a person burns. We are all born equal in this life and regardless of someones personal position, there can be no god-given right for one person to make more pollution than another. Mileage is everything, a high mileage means more damage to the roads, more contribution to congestion and more emissions. The only way to put a tax on that which is totally in line with the level of emissions produced, is on fuel. You burn more fuel, you make more pollution, you dont burn fuel, you dont make pollution.
I'm not necessarily saying this is what we should do, but if the government feels it is necessary to inflict economic pressure onto high polluters, then taxing fuel is the ONLY way to go. Singling out particular vehicle types is not only ineffective, but is absolutely wrong. Simply having a JCB parked in your garage doesnt necessarily mean you are polluting, you need to turn the engine on and drive it somewhere to do that ...and that requires ....fuel.
at the end of the day martyn, its nothing to do with emmisions or polution, its down to another mony making scam by the goverment,the uk is a dot compared to the us and china, what will are little bit do, jack s##t. are the Chinese and Americans and all the other countries in the world doing there bit no just us, just check the exchange rate with the states, how is it i can buy a product from the states half price than here, and if the products from china, it would cost more to get it to the states than here,so why is it more expensive here,an example a roll of tandy waxed thread here is £18 i just recieved from the states three rolls and the postage for the same price.how much pollution did that make getting it to me,its all just another way to hit you in the pocket, nothing to do with anything else
