Fuel duty is responsible for around £25bn of tax revenue per year, but the income from this and other forms of emission-based taxation will reduce as vehicles become greener.
The Manifesto says road pricing is not a new concept, but the advent of cheaper, more advanced technology makes it a simpler solution to this problem.
A national road pricing system could target congestion by imposing higher charges for popular stretches of road at the busiest times, thereby giving some road users the opportunity to amend the times of their driving according to a balance of necessity and cost.
Such a system would need to be a tax-neutral replacement for other fiscal sources of revenue.
What is your view on local or national road pricing?
Conservatives: In Government we’ve been clear that we don’t support national road pricing, and won’t toll existing road capacity.
Labour has no plans to introduce national road pricing or tolls.
Liberal Democrats: We have no plans to introduce national road pricing in the next parliament. However, if local authorities brought forward city centre congestion schemes, we would be prepared to consider them.
FleetNews view: Despite growing support from the fleet sector, which accounts for the majority of road traffic, no one is prepared to even consider national road pricing.
