Nothing new in the UK investigating road pricing
The UK's journey towards national road pricing has been long and arduous. It once started with the Lorry Road User Charging programme in 2002, essentially a more ambitious version of the highway heavy vehicle RUC systems in continental Europe, but that was abandoned because the business case didn't stand up at the time, given the costs. It was replaced in 2004 with National Road Pricing, which was to pioneer TDP (Time Distance Place) based road pricing, to better manage congestion. However, that collapsed due to public opposition, primarily out of concern about how much motorists would have to pay, and a lack of trust that fuel duty and vehicle excise duty would be cut at the same time.
That was 2007.
One of my big questions is whether UK politicians and policy makers have learned from that failure, and maybe learned from the successes of jurisdictions elsewhere that have partially implemented forms of RUC, such as in continental Europe, the United States and New Zealand.
House of Commons Transport Committee report
Last year, the Transport Committee of the House of Commons (UK) held an inquiry into road pricing (and also electrification of the road vehicle fleet in the UK). It released the findings of its work on 2 February 2022 with a full copy of the report available here (PDF).
The Committee notes in its report that it "launched an inquiry in December 2020 called Zero emission vehicles and road pricing. We chose to split the inquiry into two parts. We reported our findings on Zero emission vehicles in July 2021. That Report addressed the opportunities and challenges presented by the advancement of the ban on the sale of new petrol and diesel vehicles to 2030. This Report on Road pricing covers the second part of our inquiry. It examines the consequences of the shift to electric vehicles, including tackling the decline in fuel duty and vehicle excise duty."
Before I review the report's key findings, it is important for those unfamiliar with the UK to recognise that the report is influential but not binding on the UK Government. It is a matter for Cabinet and ultimately Parliament to make decisions on implementing any form of road pricing or road user charging (RUC) for the UK.
What is behind the inquiry?
- Demand impacts of no charges on electric vehicles
It's fairly simple, because it follows on from the primary reason RUC is being implemented in US and now Australian states. Revenue from fuel taxes is threatened by the shift away from fossil fuel use by road vehicles. £28 billion is the annual revenue from both fuel duty and with the UK looking to prohibit sales of petrol and diesel vehicles from 2030, it will drastically erode revenues from motor vehicles. Add the £7 billion raised from vehicle excise duty (an annual registration fee for motor vehicles) that is hypothecated to the National Roads Fund (which fully funds National Highways and contributes towards spending on local roads) and the total revenue is equivalent to 4% of all tax revenue, and this is more than just a problem for spending on roads, let alone transport. That revenue is five times what is spent on roads, so it is a general source of revenue.
In other words, unlike the US or Australia where motoring taxation barely or doesn't at all cover the cost of paying for roads, in the UK it does so and so much more. Setting aside externalities (and given no other sector pays for externalities either), the roads make a significant fiscal surplus.
However, it's not all just about money, it is also about the demand impacts. Electric vehicles pay nothing to use the roads, which means that driving is substantially cheaper for those vehicle owners than others. This is a matter of both equity, but also overall impacts on the network. If a third of vehicles are paying nothing in say ten years' time, the effects on congestion are likely to be considerable. I recall a study around twenty years ago that estimated the demand impacts of fuel duty on driving in the UK was around 10%, in other words, 10% fewer miles were driven in the UK because of the effect of fuel duty. As fuel duty has not increased in 11 years, that impact is likely to have weakened somewhat, but it still exists. So for the UK, RUC is also about sending a price signal to drivers to think about whether to drive or choose another option.
- It is difficult to predict the timescale of the impact on revenues. In 2021, 11.6% of new cars were battery electric and it is estimated by 2026, only 4% of all registered cars will be electric. (comment: Indeed, but hybrids and more fuel efficient vehicles are eroding revenues easily as much as electric. It would be wrong to focus solely on pure electric vehicles)
- However, it gets much harder to introduce RUC when there are many electric vehicles compared to when there are few, so the message needs to be sent that electric vehicles will have to pay to use the roads. (comment: agree)
- A shift to electric vehicles could increase "traffic levels" by 51% by 2050 according to the Department for Transport (DfT), with the average driver spending an additional nine hours a year in traffic by 2040. (comment: "on average" hides some disparities, but the aggregate impact is likely to be true. Cheaper driving will mean more driving).
- "Any alternative road pricing mechanism must be revenue neutral to the Government rather than causing drivers, as a whole, to pay more than they do currently. Such a mechanism should be phased in before fuel duty and vehicle excise duty decline to zero. The situation is urgent; work must begin without delay" (comment: YES absolutely)
- Technology already built into vehicles (in-vehicle telematics) has potential to collect and deliver the data necessary for a road pricing system (comment: Yes, and this happens already today on a small scale in Utah).
- "The Government must assess the potential effect of a road pricing mechanism based on telematic technology on high-mileage drivers, such as road hauliers and those in rural communities, and on those least able to adapt to increased motoring costs." (comment: Yes there should be modelling and even piloting of road pricing to assess those impacts. Noting that road hauliers should see the HGV Levy replaced by RUC, but rate setting needs some serious policy analysis. A cost allocation study should be carried out).
- "The successful implementation of a national, technology-based road pricing scheme is contingent on the Government explaining how data capture will work in practice, ensuring that data management is subject to rigorous governance and oversight and reassuring the public that their privacy will be protected" (comment: Data privacy is critical, but there needs to be acknowledgement of some obvious ways to ensure this, such as not having a government owned RUC system collecting trip data, specifying the level of location disaggregation needed, consider having a non-location aware option (at least for a transition period))
- The DfT and Treasury should set up an arms-length body to investigate and evaluate options to replace fuel duty and vehicle excise duty (comment: This seems reasonable, but there isn't an actual need to replace vehicle excise duty. Vehicle excise duty is only an issue because electric vehicles are exempt, but that exemption need not be maintained. However, there are merits in shifting from ownership based to usage based charging of motor vehicles).
- (para. 25) A claim that the UK can be a "world leader" in road pricing, is bold but also maybe fanciful, especially given how little progress has been made in the UK compared with other jurisdictions. The report doesn't note that there are three and soon to be four jurisdictions charging light vehicles (in all cases but one, electric vehicles) by distance instead of fuel duty. There are two jurisdictions that charge heavy vehicles by distance, weight and configuration instead of fuel duty. There are twelve jurisdictions that charge heavy vehicle by distance and weight as well as fuel duty, using GNSS technologies. However there is very little citing of relevant international experience. Is that because most of those who gave evidence have no such experience> There are multiple companies in Europe, the US and New Zealand that run RUC account management operations, including supplying technology for vehicles (heavy and light). If the UK WAS able to implement a national road pricing scheme that included congestion pricing based on distance it might be world leading (although I suspect Singapore might beat it), but it has so far proven that it cannot even roll out a basic cordon or area based congestion charge beyond London and Durham after 21 years.
- (para. 28) The claim is that "The devolution of road pricing could lead to the introduction of clunky, unconnected schemes that charge users the same price for driving one mile into the zone as those who drive across it for hours in a day. The more regional schemes that are created, the harder it will eventually be for the Government to implement a functional national system". This is simply nonsense, not only because it is based on the idea that there is only ONE type of congestion pricing scheme (cordon or area charges) and only one way to implement it (assuming there is a flat all day charge). Why can local schemes not work with a national system? The US looks like it may have multiple state RUC systems and ultimately federal system, which may all be interoperable and function seamlessly. Several European countries have toll schemes plus heavy vehicle RUC systems operating in parallel (see Belgium which has a national heavy vehicle RUC scheme, with Brussels developing a local congestion based scheme for light vehicles). New Zealand has a national RUC system and is investigating a local congestion pricing scheme for Auckland. There MIGHT be a problem if systems require multiple accounts, or multiple pieces of on-board equipment, but this is unnecessary and avoidable. It is likely to be lower risk for congestion pricing to be locally defined and implemented, even if nationally regulated. It seems to be an excessively engineering rather than policy and business based perspective.
- (para. 32) The report cites John Siraut from Jacobs who says:
"He stated that a system where charges vary dynamically based on the road being used and the time of travel are “certainly perfectly feasible to do”, even though they do not exist at the moment"This is simply wrong. There IS a system that varies by location, time of day and charges by distance, in the Czech heavy vehicle RUC system. For heavy vehicles, the charges vary based on the type of road (motorway vs. 1st class highways) and the time of day. Arguably, Singapore also has a system that varies by road being used and time of travel since.. 1997 (albeit not charging by distance), but certainly the can rates vary across 78 charging points by small increments of time of day. Strange in particular when he is previously cited as saying "Singapore comes closest" to the model discussed, which suggests he may have been misquoted at least once. . (Disclaimer: I used to work for a wholly owned subsidiary of Jacobs, in the UK from 2012-2015).
(para. 34) The report says "The Government must assess the potential effect of telematic technology on changing drivers’ behaviour and delivering its wider policies on air quality, congestion, public transport and public health.". No, the effects of telematics technology on drivers' behaviour should be minimal. It is about the policy that is implemented, not the technology (although technology is the enabler). Furthermore, if you think introducing road pricing should also address a whole host of externalities, then you'll spend another five to ten years investigating it. This seems like an unwelcome and unnecessary distraction. The effect on environmental and transport policy outcomes will depend on the policy selected.
- Road pricing means paying a lot more to drive
- Road pricing means tracking everywhere that you drive
- RUC rates that are based on a rational economic assessment of what different types of vehicles should pay.
- Charges that don't vary by time of day until a vast majority of vehicle are on a system
- Charges that vary by road type and location for traffic management purposes, but not to such an extent as to encourage use of vehicles that do not pay RUC
- Hypothecation of some revenue for roads, to go beyond what the National Roads Fund does now
- Care being taken as to how to treat the surplus of revenue beyond what is needed for roads.
- A feasible staged transition path.
