It is a pleasure to serve under your chairmanship, Mr Dowd. The draft regulations will be made under the powers conferred by sections 41(1), (2)(d), (3) and (5) of the Road Traffic Act 1988. They implement increases in weight limits by up to a maximum of 1 tonne for certain alternatively fuelled heavy goods vehicles and by a flat 2 tonnes for certain zero-emission vehicles. In all cases, the maximum weight limits for individual axles will remain unchanged.

No additional weight allowance for zero-emission or alternatively fuelled vehicles will apply to the heaviest articulated lorry and road train combinations, of 44 tonnes, or to four-axle motor vehicles of 32 tonnes. The extra weight allowances do apply to articulated lorries and roadtrain combinations with five or six axles, normally limited to 40 tonnes. They also apply to four-axle combinations, normally limited to 36 or 38 tonnes, and to certain smaller zero-emission lorries with two or three axles. In addition, they apply to zero-emission three-axle articulated buses. Two or three-axle alternatively fuelled versions of these types can already operate at up to 1 tonne above the normal limits.

I very much welcome the instrument the Minister is bringing forward. It will help to deliver the Government’s net zero strategy by encouraging the adoption of ultra low and zero-emission vehicles. Does he agree that encouraging the switch to lower-carbon and zero-carbon driving is a better way to address climate and pollution matters than trying to drive vehicles off the road through things such as the ultra low emission zone in London?

The agreement applies to vehicles used on international journeys and to EU vehicles operating in the UK on cabotage. The allowances are to accommodate the additional weight of alternative fuel technology up to a maximum of 1 tonne and, for a zero-emission technology, 2 extra tonnes.

To put the regulations in context, transport is the biggest greenhouse gas-emitting sector of our economy, and road freight is a significant contributor to that. In 2021, HGVs produced around 20% of greenhouse gas emissions from our domestic transport network. Utilising zero-emission and alternatively fuelled freight vehicles can contribute positively to freight decarbonisation and help with achieving the UK’s commitment to reach net zero by 2050.

A vehicle’s powertrain consists of the components that generate power and then transmit it to the road to move the vehicle. Currently, alternatively fuelled and zero-emission heavy goods vehicles may have a heavier powertrain technology than traditionally fuelled internal combustion engine heavy goods vehicles. For example, a pressurised fuel tank in an alternatively fuelled vehicle, or batteries in a zero-emission vehicle, can be significantly heavier than a conventional petrol or diesel fuel tank—I saw some examples recently on a visit to DHL in the midlands.

The typically heavier powertrains of these vehicles mean that, under current regulations, alternatively fuelled and zero-emission HGVs may have to carry a reduced amount of cargo than comparable fossil fuel vehicles. This places them at a competitive disadvantage. The higher weight of the empty vehicles acts as a payload penalty, which then decreases the commercial viability of zero or lower-emission vehicles.

The regulations would afford zero-emission vehicles a weight increase of 2 tonnes, as opposed to the maximum 1 tonne increase offered to alternatively fuelled vehicles, as the features that make them zero emission—particularly the batteries—are likely to be heavier, although I think we all hope that these provisions will be needed less as the technology continues to improve over time. This approach further incentivises the uptake of zero-emission vehicles, bringing potential benefits via emission reductions.

A public consultation asking whether to permit alternatively fuelled or zero-emission vehicles to have that slightly higher weight limit was carried out between 14 July and 3 September 2021 as part of a wider consultation on the phase-out dates for sales of new non-zero-emission heavy goods vehicles. Of the responses received, 59% were in favour of the increase in weight limits, with only 6% opposed and the remainder being “Don’t know”. A Government response confirming our intention to introduce these changes was published on 12 May 2022.

Let me turn to the contents of the statutory instrument. Amendments will be made to the Road Vehicles (Authorised Weight) Regulations 1998 by making provision to increase the maximum authorised weight for certain alternatively fuelled and zero-emission vehicles. Amendments will also be made to add a definition of “zero-emission vehicle”. The regulations provide for the Secretary of State to undertake a review of the regulatory provision contained in these regulations on a five-yearly basis. That is to account for the rapid deployment of technology and to ensure that increased weight limits remain suitable.

To conclude, the regulations are essential for supporting the commercial viability of zero-emission and alternatively fuelled commercial heavy goods vehicles. They do not involve any regulatory burden on domestic road freight operators. Instead, they aim to give flexibility to those using zero-emission or alternatively fuelled HGVs. The de minimis assessment identifies a best-estimate monetised net present value over the years of £18.2 million, which relates to the greater business efficiency as a result of these measures. There are also unmonetised costs, such as infrastructure costs, and unmonetised benefits, such as a reduction in greenhouse gas emissions. The regulations will also ensure parity of regulation, meaning that domestic operators will not be placed at a disadvantage to their European counterparts. I hope Members will join me in supporting the regulations, and I commend them to the Committee.

It is a pleasure to serve under your chairpersonship, Mr Dowd. Decarbonising our roads is a vital part of meeting our net zero obligations. As our haulage sector moves towards electric and alternatively fuelled HGVs, it is right that regulations adapt to the heavier powertrains these vehicles carry. I note that the consultation outcome was largely in favour of that approach, but there are a few points that I hope the Minister can address.

To conclude, we must not miss this opportunity to decarbonise our transport sector and encourage a switch to zero-emission vehicles. The Labour party will therefore not oppose these regulations.

The hon. Lady talked more broadly about our road network. It is important to reflect on the fact that the UK Government are still investing in our road network and making substantial improvements. I was up in the north-west recently and saw a road being built to better connect Blackpool to the M6. It is a shame that some of the devolved Administrations across the country, and particularly Wales, are rejecting any form of new road building, especially when we are now seeing this major shift, in terms of our road network capacity, to low-emission and zero-emission vehicles. The road network has an important role to play in decarbonising our economy, while ensuring that opportunity for people is spread right across the country and that they can remain as connected as possible.

To conclude, I hope the Committee has found the debate informative and that it will join me in supporting the regulations, which will amend legislation to allow weight increases by up to 1 tonne for alternatively fuelled vehicles and by 2 tonnes for zero-emission vehicles. These changes are to support the commercial viability of those vehicles and to ensure regulatory harmony with our international competitors. Adaptation of these vehicle types will help reduce emissions from what has to date been a hard-to-abate part of the transport system, moving us closer to our 2050 net zero target.
