What a cheek to charge 50% extra parking for us diesel drivers. What about all the freight that now has to be transported across the country by road, huge diesel engines in those lorries, all because some government chose to take an axe to the rail network years ago. The government should take it upon themselves to stop shirking their responsibility in all of this, they over the years have forced this issue, first by the rail network, then trying to get more people to switch to diesel engined cars, its a disgrace this is. It will also mean a huge cost to the councils because for them to make the charge effective, they will need to update all parking meters to ones where you have to enter your registration number, so that the meter can then via internet / network check what you car is powered by in order to actually collect this increase in fees. If this then rolls out across the UK, it will carry a massive extra cost just for the infrastructure to support it, who will ultimately be carrying this extra cost we, the public.
