The Parliamentary Under-Secretary of State for Environment, Food and Rural Affairs (Rory Stewart)
It is a great pleasure to serve under your chairmanship eventually, Mrs Moon. As your husband was a distinguished ecologist and created the local government network of ecologists, I am pleased that it should be an environmental subject that I have the privilege of presenting in front of you. I thank my hon. Friend the Member for Bath (Ben Howlett) for securing this debate and thank others for their contributions, which I will try to wrap together, to consider what is a surprisingly tricky, important and evolving subject.
The first question is one of science, about which the hon. Member for York Central (Rachael Maskell) made several points in a couple of interventions. One of which was about the chemistry of diesel engines and their nitrogen dioxide content. I think that she was getting at the fact that diesel burns at a different temperature to petrol, producing more nitrogen dioxide. She also pointed out that some emissions may come from technically low emission vehicles. Nitrogen dioxide is our major concern today, but we are also concerned about particulate matter, and, as others mentioned in the debate, sources of emissions extend to other things apart from vehicles, including non-road mobile machinery, such as construction machinery, and domestic boilers. The sources extend right across the spectrum of vehicles, including buses, taxis, heavy goods vehicles, light goods vehicles and cars.
The hon. Member for Blaenau Gwent (Nick Smith), the shadow Minister, also focused on science and modelling. The modelling that we undertake in Britain is sophisticated, taking nearly three months to run, and European Union-accredited. It is unbelievably complicated, involving the overlaying of emissions and the balance of the fleet. For example, when my right hon. Friend the Member for East Yorkshire (Sir Greg Knight) is driving through his area, his vehicle will have an impact on emissions in a particular place, and the hon. Member for Strangford (Jim Shannon) mentioned emissions from planes, which need to be put into a totally different part of the model due to atmospheric dispersion. The model therefore includes sources of emissions, a climate model, including how the wind moves things around, and the road network, and out of that we attempt to calculate nationally the number of micrograms per cubic metre. As pointed out by the shadow Minister and my hon. Friend the Member for Bath, local situations will always arise in which things are being captured that may not be captured by the national model. Equally, the national model will be much better at reliably catching the national picture than can be achieved on a grid basis.
The shadow Minister mentioned Oxford Street, and I absolutely agree that the situation is shocking. It is terrible that the levels, at 120 micrograms per cubic metre, are three times the EU limit. However, I gently challenge the idea that that is the worst in the world. Someone on a visit to Beijing, Delhi or a number of cities in Latin America will find considerably higher levels, but the situation on Oxford Street is indeed shocking. Such levels will have a serious impact on human health, which was raised by the hon. Member for Strangford.
There is also the question of cost: what do we do about the problem, and where do we allocate the costs? We now have a better understanding of the cost to human health, which has two elements. There is the indirect cost to human health. There is the value that we put on our own lives and the fact that people, if they have lung diseases or heart diseases, may die prematurely. The Treasury attaches an economic value to that, which is a slightly bizarre process. There is also the direct cost to the national health service of trying to treat people. The hon. Member for Strangford challenged us to try to integrate much more how we use the NHS budget, public health, how we think about air quality and the measures that might be taken by my Department or the Department for Transport.
I am grateful to the hon. Member for Falkirk (John Mc Nally) for his speech. His example—as he said himself, it was perhaps more Dundee than Falkirk—shows how we can learn from the devolved Administrations again and again. In environmental policy, we are already learning from Wales’s approach to recycling and from Scotland, in particular Zero Waste Scotland. Different approaches are often taken across borders. The Dundee example of electric vehicles and potentially electric bicycles is something that we are happy to learn from, and we are happy to exchange ideas across borders.
The fundamental challenge posed by the hon. Member for Bath and the shadow Minister was, “What on earth do we do about this? How do we address these problems?” The shadow Minister put his finger on two problems, one of which was how to get the balance right between the national and the local. He was saying that it is all very well the Department pontificating and saying, “This is where we want to get to,” but the local authorities are given the job of responding to it without resources. The other problem was how to allocate the resources and costs, which was also the challenge of the hon. Member for Strangford.
One way of understanding the dilemma is to look closely at the exact example raised by the hon. Member for Bath. How does the balance work? Bath, fortunately, is modelled not to be in exceedance by 2020. This is a devolved issue, but the cities we are particularly concerned about in England are Birmingham, Leeds, Nottingham, Derby, Southampton and London. They are our major concerns and we have a different approach to each city—Bath is a good example. Forty micrograms per cubic metre on average of ambient air quality is an EU-set target, but we want to do better than that, because of the benefits to human health. We would like to reach the target sooner rather than later.
Since Roman times, Bath has been a great symbol of health in this country. It was where Roman tourists and 18th century tourists alike went for their health; it is a world heritage site based on the idea of health. We should certainly have a clean air zone in a place that is seen as a great symbol of health.
The council in Bath has led in a number of ways. This is a good example of the local-national thing. The council already has an extraordinary project on bicycles—Bath’s answer to the Boris bike—which has just launched and has 5,000 bikes in operation. The council has a good approach to electric vehicle charging and has more than 20 electric vehicle charging points, with businesses also building their own charging points. It has invested in hybrid buses. The Department for Environment, Food and Rural Affairs has been proud to co-operate in a small way on the Bath website and on some of the research into moving towards low emission vehicles. Now Bath has come forward with a proposal to have its own low emission zone, which we welcome.
There has to be a national contribution, which I will set out in a moment, but the reason why getting the balance between local and national is vital is that we can see in a single road such as Rossiter Road in Bath an exceedance reduced by 18 micrograms per cubic metre through a single local intervention. It is not sensible for the Department to fantasise that, sitting here in London with a 300-mile screwdriver, we have a solution for 28 cities. Much will be about having active traffic management systems.
One Labour MP, the hon. Member for Southampton, Test (Dr Whitehead), came to me with a brilliant idea about how to resolve diesel pollution issues caused by passenger vessels docking in port. It involved setting up electricity charging points, so that the vessels did not have to run off their diesel engines. He found a solution that involves the local enterprise partnership and the local council. Such solutions can have much more of an impact much more rapidly than our simply mandating things from the centre.
As for cities where we will be in exceedance by 2020, however, we are clear that we will take action. The Government are determined to be in compliance. In 2020, we will be judged on whether we are below 40 micrograms per cubic metre in every city in England, with the exception of London, and we will be in compliance in London by 2025. We will ensure that we put structures in place to support local initiatives.
My hon. Friend the Member for Bath made a final challenge: can we produce a standardised system of low emission zones to be rolled out across the cities? Yes, of course we can. The point of our consultation is to provide four straightforward models of what low emission zones—what we call clean air zones—can look like. The first model deals with buses and taxis; the second with buses, taxis and heavy goods vehicles; the third with buses, taxis, HGVs and light goods vehicles; and the fourth one goes all the way down to cars.
Sir Greg Knight
Does the Minister agree with me and the Mayor of London that there is a case for exempting historic vehicles from any restrictions or penalties?
Rory Stewart
My right hon. Friend makes a powerful point and one we will have to think about. We have to get the balance with simplicity right, and that is what we are trying to achieve. The request made by my hon. Friend the Member for Bath for a straightforward, simple system was a good one. The objective is for an HGV driver to know that the same rules apply throughout England or, ideally, if we can work with the devolved Administrations, throughout the United Kingdom, so that we do not have different rules in different places. Provided we can achieve simplicity and a national standard, however, I can see a good argument for excluding historic vehicles. In essence, because the low emission zones would be standard, provided that HGV drivers had a Euro 6 diesel engine in their lorry, for example, they would know that they could enter any of the zones anywhere in the country, as such vehicles would be exempt. We do not want to end up with a situation in which any individual business has no idea what is happening when it turns up somewhere.
We have made some progress since the 1970s. The hon. Member for Strangford reminded us about the problems of smog, which were much worse. In the late 1940s, some incidents cost thousands of lives over two or three days. Since then, we have reduced sulphur dioxide by a dramatic 90%, which was an extraordinary achievement, particulate matter by 73% and the nitrogen oxides, NOx, by 62%, but we can still do better and we have a huge opportunity to do so. The Government have put £2 billion into that.
The real game in town is to ensure not only that by 2020 or 2025 we meet the targets, but that by 2050 we are in the lead and that, with the exception of my right hon. Friend the Member for East Yorkshire and his exotic car, we are predominantly driving electric vehicles. We can see the direction in which we are going: Britain should be in the industrial lead, and we should be the country where such vehicles are manufactured and tested.
Jim Shannon
I thank the Minister for his comprehensive reply. In my contribution, I mentioned the example of what Berlin had done. I am sure he is coming to it, but I was hoping to hear his thoughts on that.
Rory Stewart
The Berlin model is interesting in a couple of ways. First, it has had a good result; the system was put in quite early. Secondly, it was done without cameras. The German system is simply to say, “You will not drive into the centre of Berlin if you have less than a”—I cannot remember exactly what the rules are, but people must have in their vehicles something along the lines of a better than Euro 4 petrol engine or a better than Euro 6 diesel engine. However, there are no cameras to monitor licence plates. The German citizen appears to be so law-abiding that the system relies simply on the police to turn up and inspect the tax disc.
Our assumption is that we would do better to follow the London example of having cameras to recognise people’s number plates, rather than relying on that German system, which is nevertheless an example of how Berlin achieved something pretty remarkable at a very low cost. It did not have to put up any camera infrastructure, or do anything at all; the authorities simply told people not to drive in with certain vehicles and, in essence, that was that.
Rachael Maskell
I note the Minister’s concern about some of the larger cities, but some of the smaller cities and in particular, as we have heard today, the historic cities have problems and pockets of very high emissions, which cause concern. Will he look specifically at some of our historic cities to ensure that they can be part of the wider programme to reduce emissions?
Rory Stewart
Let me take the opportunity to conclude on exactly that point, because the hon. Lady has summed up our discussion: it is about exactly that balance between local knowledge and national.
The whole point of our consultation is to feed in the complexities. One thing that we have picked up is that there is, of course, a real problem with historic cities. The problem can be geographical; my hon. Friend the Member for Bath said that his city in essence sits in a bowl, and the pollution tends to congregate in it. The problem in York is a medieval street network, or just narrow streets, as potentially in the centre of Leeds, creating a real problem of congestion. A diesel engine might run well on the open road, but the problem is that, as soon as the vehicle gets stuck on a hill, its engine is pumping out a great deal of particulate matter and nitrogen dioxide. That is why we want our process to be an open one that embraces the offers made by York and Bath, gets behind them and clears the obstacles out of the way.
The Government’s main objective must be to bring into compliance cities that are not in compliance. However, as I said, the European target is simply a compliance level and we really encourage people to do better. Any city that wants to do better will find a huge benefit for human health and tourism: Bath alone, with its millions of visitors, is bringing in £400 million a year in tourism. It will also be good for businesses. We want this country to be a place where people are proud to breathe the air.
Ben Howlett
One of the key issues in historic cities, however, is that while we may have the ambition of introducing electric cars, we cannot just dig up the roads to introduce electric car charging points. One thing we are having a lot of difficulty with is getting through the planning process to introduce charging points in cities. Will the Minister guarantee that he will go away and work with the Department for Communities and Local Government to streamline the planning system for electric car charging points?
Rory Stewart
That is a very good challenge, which will apply to many of us. We see the same challenge in the installation of broadband and insulating historic buildings, as well as in electric infrastructure, and DEFRA tries to use different mechanisms to address that. We sit on taskforces on housing and infrastructure, which provide good opportunities to raise that point. I absolutely take the point that historic cities are different. They operate differently and it will not always be possible to have a solution for an historic city that can be applied to a new city.
Nick Smith
I thank the Minister for accepting my intervention and for his contribution. There seems to be a lot of willingness across the UK to introduce these schemes and he has spoken about introducing cameras and background administrative systems to help implement them, so how will the Government financially help local authorities to implement these good ideas?
Rory Stewart
The answer to that, I am afraid, is that we are still completing our consultation on the plan. The plan will be printed by the end of the year and a final answer will be presented to the shadow Minister on exactly that. We have just compiled more than 700 different responses and we are going through them to try to understand what local authorities wish to do in their different towns. We are trying to work out how many projects will involve cameras and how many will involve light goods vehicles, HGVs and taxis. Some will want to invest money in hybrid buses, while others will want to go for electric charging schemes and others will want active traffic management systems to move traffic around in different directions.
The plan, which will be the answer to that, will be scrutinised carefully by the Opposition and also by ClientEarth, the Supreme Court and the European Commission, all of whom will look at it to ensure that they can be confident that we can deliver by 2020. That is the document that we wish to present at the end of this year.
I thank all right hon. and hon. Members for attending. This is a really important issue on a change. We did not know much about nitrogen dioxide until relatively recently: the first scientific evidence on it came out of when the “Six Cities” study in the United States that began on particulate matter and moved on to nitrogen dioxide began to identify correlations between pollution and morbidity. We still do not completely understand the chemical processes and health implications. We know that there is some kind of correlation between these substances and effects on human health and that we have to act to reduce these substances, but this is something that Governments were not really focused on even as recently as five to seven years ago.
Science is changing all the time. New research is coming in and we have doubled our numbers in a lot of these areas. I am very grateful to those who have participated in the debate and we look forward to working with everyone around the table and every local authority and devolved Administration to ensure that we provide what everyone in the United Kingdom wants: that the invisible substance that we breathe and on which we depend and our children’s lungs depend is safe and clean and that British air remains something that we proudly breathe.
Question put and agreed to.
Resolved,
That this House has considered the introduction of low emission zones.
