Four entirely different charges. You could simplify that to one, but then you have a myriad of combinations for car size, cc, weight, and mileage. I agree we need an emissions fee in the future. If it was a bit silly why have the exiting charges been kept seperate? Its simpler. In any case thats all irrelevant, we either agree or disagree on a future emissions charge or we don't, and we do. How they are billed is just an admin issue
1) we already have an emissions fee...have since 2010..
Do we? So how do I pay my fee as I drive two petrol cars, and how do the EV users avoid that fee? It would have been helpful to provide info on it
