Greater London Low Emission Zone Charging (Amendment) Bill

Debate between Kerry McCarthy and Lilian Greenwood

Friday 22nd March 2024 Commons Chamber

[Lilian Greenwood]

Unusual as it is for the Minister to intervene, I think the point was made by my hon. Friend the Member for Eltham (Clive Efford). When people from outside London drive into London, the costs of that in terms of health, and wear and tear on the roads, is borne by constituents here in London. It is not unreasonable for them to expect that those who benefit from everything that London has to offer, who travel into the centre causing congestion and poor air quality, should abide by the well-established principle that the polluter pays.

[Kerry McCarthy]

This goes back to what I was saying about the fact that the Government insisted that Bristol had a clean air zone. Obviously that will have a significant impact on people from Bath, for example, who drive down the A4 into my constituency, causing a huge amount of congestion and air pollution, but that is basically how politics works. I entirely agree with what my hon. Friend just said: the duty of politicians is to look after people in the patch they represent.

[Lilian Greenwood]

My hon. Friend is exactly right. I will come on to address how we best tackle the issue of air pollution and, at the same time, protect those who are impacted by this charge.

From 21 August last year, every Londoner with a non-compliant vehicle became eligible for a £2,000 grant to assist them in replacing their vehicle. I understand why people have said that £2,000 is not enough, but that has been provided despite central Government giving no financial support to the Mayor of London for it. Of course, if the Government are concerned about the impact—[Interruption.] If they are concerned about the impact of their clean air charging zones, they could have provided additional assistance—

[Kerry McCarthy]

London has the Greater London Assembly, a Mayor with devolved powers and Transport for London, so this issue is looked at on a London-wide basis. There is an issue in Bristol with people coming into the city centre from places like Bath, but the boroughs are not so interwoven that we cannot see the borders between them, and we do not have the interconnectivity that London has. In Bristol, we were told that we had to bring air pollution levels within legal limits as quickly as possible. We went to great lengths with the modelling to deal with concerns about the economic and social impact. As the Minister said, making the zone as small as possible was one of the factors in that.

It is relevant to talk about the Bristol scheme because it shows what can be achieved by similar measures in London. The scheme came into effect in November 2022, and in January this year we had the first annual report on its effectiveness. It was judged to have been highly successful. The headline figure was that air pollution across all measured sites had declined by 9.7%. The success of the CAZ is measured by whether it lowers nitrogen dioxide levels below the legal limit of 40 micrograms per cubic metre. In November 2022, when the scheme was introduced, there were 18 sites across Bristol above the legal limit. Just 12 months later, that was down to just six zones. The scheme was particularly effective outside the Bristol Royal Infirmary and the Bristol Children’s Hospital, which are bang in the middle of the city centre. Air pollution was down by an incredible 26.9%. I defy anyone to tell me that such big improvements in air quality in areas where there are very sick and vulnerable people, including sick children, is a bad thing. It has been really successful.

[Lilian Greenwood]

Does my hon. Friend share my concern that this is sometimes presented as a binary choice between motorists and everybody else, such as the children in the hospital, when these improvements are actually beneficial for everyone? One thing that came out of the 2018 report is that some of the worst air quality is inside vehicles, so motorists directly benefit from improvements in air quality.

[Kerry McCarthy]

I was on the Environmental Audit Committee and the Environment, Food and Rural Affairs Committee at the time, both of which took part in that inquiry. It was difficult to bring those Committees together, but the inquiry produced a really good, significant report, which we should still pay heed to when we as House think about what to do on this issue going forward.

[Kerry McCarthy]

My right hon. Friend is absolutely correct. I did have an e-bike; it was stolen from inside the Houses of Parliament. One would think that there would be nowhere more secure, but when the Queen was lying in state, whoever was acting as her security removed all the bikes and took off a £130 lock—presumably with an angle grinder or something—and my bike was not seen again. Try explaining to the insurance company that it was people from Buckingham Palace or from the Queen’s lying in state who took the lock off! That is another story, though.

My right hon. Friend is entirely right. I used to hold the shadow green transport brief, and e-bikes are hugely important in allowing people to do those longer journeys. I could not make it up the hills in Bristol without a bit of extra help from an e-bike, but when it comes to delivery vehicles, one of the issues is deliveries inside the areas covered by zones. If we can have hubs outside the city centres and electric vans or e-cargo bikes making those deliveries, that could have a huge impact. Obviously, everybody making food deliveries and similar things really ought to be using clean modes of transport.

I am conscious of time, so I will finish my point about the Bristol scheme. There were concerns that it would lead people to take diversions and increase pollution outside the clean air zone, but air pollution outside the zone has also been measured as down: it has reduced by 7.8%, because the CAZ has encouraged a modal shift among people. I appreciate that people cannot always afford to make that shift in vehicles, but it has happened.

Another concern raised by opponents was that the CAZ would harm the local economy and communities by discouraging people from coming into the city centre. In fact, the opposite happened: retail footfall across four major retail hotspots in central Bristol actually rose from the previous year. There was also an argument that people would become isolated and stuck at home because they could not afford to pay the £9 charge, but again, that was not the case: the number of journeys into or through the CAZ per month was higher at the end of the year than at the start of the scheme, and the percentage of compliant journeys rose every single month. That is what we want to achieve.

It is the same with the landfill tax, for example. That tax is not about raising money because lots of people are sending stuff to landfill. If a landfill tax is effective, the revenues go down and down, year on year. There is actually an issue with the fact that the tax is not keeping pace with inflation at the moment, but assuming it is effective, the revenues will dwindle—it is the behaviour change that we want to make happen. As I said, ideally we would not have introduced a clean air zone, but we have made it work. It is also worth noting that the Government take £2 from every £9 CAZ charge, which we would very much like to be able to spend in Bristol instead.

[Lilian Greenwood]

It is quite difficult to assess the effectiveness of a clean air zone, because it is not about whether vehicle numbers go down, but about whether those numbers are higher or lower than they would have been if we had done nothing. When thinking about the effectiveness of ULEZ in central London, for example, we need to model what would have happened if we had not had ULEZ, rather than just look at whether the numbers have gone up or down.

[Kerry McCarthy]

Exactly—there is very complicated modelling involved. Also, if we can use measures such as these to take some cars off the road, that increases the attractiveness of public transport, because the buses can get to where they are meant to be without being stuck in traffic.
