IFS advice on moving from fuel duty to taxing road use

This proposal from the IFS raises so many issues, some clearly public policy concerns with proposals intended to ease congestion and raise charges for driving in congested or busy areas. But it also raises practical implementation issues like how road use charges would be determined and collected with the prospect of varying levels of charges for particular roads and at different times in the day.

For limited mileage classic car enthusiasts the impact might be small unless a higher road use charge is applied for vehicles not meeting the low emissions levels achieved by modern cars.

In a paper released by the Institute for Fiscal Studies on 8th May 2015 before the result of the UK General Election was known, Paul Johnson set out "five pieces of general advice on what is needed for tax policy for whoever is the new government" together with "more specific pieces of advice aimed at particular parts of the tax system". The sixth piece of specific advice included the following recommendation on moving from taxing motor fuel to taxing road use:
6. Set out a plan to move us from taxing road fuel to road use
Fuel duties raise over £25 billion a year. But it seems to have become politically very difficult to raise their level even in line with inflation, so real revenues are falling. If we are to get anywhere close to meeting legislated targets for greenhouse gas emissions, we will have to move away from reliance on petrol and diesel, so revenues will eventually fall drastically. And from an economic point of view fuel duties are very poor at targeting congestion, the main problem caused by road use. In the end we are likely to be forced into moving towards some form of road-user charging. Recognise that and prepare for it.


The paper ends with an amusing self congratulatory comment - "So there you have it Chancellor. I wouldn’t expect you to do all of that in one term. But if you were to make a start on just some of it you would be a hero to public finance economists for decades to come. What other reward could any Chancellor desire!"
