Zero-emission Buses and Air Quality in Sheffield

Debate between Anthony Browne and Ian Paisley

Tuesday 5th December 2023 Westminster Hall

[Anthony Browne]

That is a valid point. Clean air zones impose costs on people, but they are only necessary and only required where air pollution is above the legal limit. In those places, not only are we required to introduce them by law, but it is the right thing to do to reduce air pollution as quickly as possible. The clean air zones are temporary. They are there only while air pollution exceeds the permitted levels. Clean air zones are supported by the Government, but the design and structure of them, including which vehicles are included or excluded, and their funding are decided by local authorities. As a result, all the clean air zones in the country are variations on a theme. For example, ordinary cars are not included in the Sheffield scheme, but taxis are. It is different in other places.

Because of the need to act quickly, the Government introduced the retrofit programme. As the hon. Member for Sheffield Central mentioned, that has been troubled. I have been in this job for three weeks, and it has landed on my plate. As he says, it has not performed as we expected in real-world conditions. We are currently analysing exactly what the impact is and what the mitigations can be, and we will publish the results soon. I cannot release them now—we need to make exec decisions—but when we do, it will be within the framework of eliminating air pollution in Sheffield and other cities as quickly as possible, as we are legally required to do, and as is the right thing to do.

[Ian Paisley]

Sheffield has an application under ZEBRA 2. Those applications close at the end of December, I think. Does the Minister agree that something the Government could do is make sure that by the end of January, or the beginning of February at the very latest, those decisions are taken, the contract is offered, and we move on to ZEBRA 3 and get all of the £400 million spent on these carbon-zero buses?

[Anthony Browne]

I will come to the hon. Member’s point. The retrofitting programme was only ever going to be an interim scheme, because those were the buses we had at that moment. As basically all other hon. Members have said, the ultimate long-term ambition is to go to zero-emission buses, for reasons of both climate change and air pollution. In the national bus strategy in 2020, the Government committed to 4,000 zero-emission buses; 1,600 of them are on the road at the moment. We have been pushing that in a variety of ways. We are also committed to announcing a date for the phasing out of non-zero-emission buses, which will be done in the near future.

There are two schemes for zero-emission buses at the moment. First, there was ZEBRA 1, which provided £270 million of funding. The beneficiaries included Sheffield, which got four buses, which will start in January, and the South Yorkshire metropolitan area, which got 27 zero-emission buses. We then opened ZEBRA 2. I know that the hon. Member for Sheffield Central wrote to one of my predecessors expressing interest from Sheffield in that scheme, and that Sheffield has lodged expressions of interest, which is great. The deadline is 15 December. I cannot announce the results, because the applications are not in yet.

On the request from the hon. Member for North Antrim (Ian Paisley), we want to act as quickly as possible. I will certainly urge officials to announce the outcomes of the bid as quickly as possible because, as I said, we want to act quickly for reasons of both climate change and air pollution.

Various hon. Members mentioned hydrogen buses. The UK Government are technologically neutral: we have been very careful to try not to say that one technology will work and another technology will not, not least because we do not know how technology is going to progress. There are also very varying conditions, and one type of technology might be better in one situation compared with another.

The hon. Members for Sheffield Central and for Sheffield South East (Mr Betts) mentioned hills and the challenges they pose for battery buses. For longer ranges—there are buses in rural areas that have to go far longer distances—hydrogen buses may turn out to be more suitable than battery buses. However, I know that battery technology is advancing very rapidly. If we compare the debate now with a few years ago and five years ago, certainly from a manufacturer’s point of view, there is a lot more emphasis on batteries as the ultimate solution, rather than hydrogen. The price of batteries has dropped by 90% since 2010 and the range is increasing by about 10% a year—it has increased by about 45% over the last four years. Hopefully, those technological improvements will continue and help us to decarbonise all forms of transport in cost-effective ways.

We are supporting hydrogen. There are various Government programmes supporting hydrogen buses. The Government provided £30 million to support the West Midlands Combined Authority’s scheme for hydrogen buses, which are about to be launched there. The ultra-low and low-emission bus fund is supporting 20 hydrogen buses in Liverpool, and there are other hydrogen buses elsewhere. We will carry on supporting that, because hydrogen could end up being the absolutely appropriate technology for certain situations.
