Improving Air Quality

Philippa Whitford Excerpts

Thursday 28th June 2018 Commons Chamber

[Neil Parish]

The hon. Lady, who chairs the Transport Committee, is absolutely right that the money would be well spent. Our health would be improved, and therefore we would save money on the NHS and we would be able to spend the money in other ways.

Why are there private individuals in this country who are prepared to bring a case against VW, yet we, as a Government, have singly failed? I would be interested if the Minister could give us some insight into why we allow private people, quite rightly, to bring a case, yet the Government are not supporting them and are not bringing a case themselves.

There is not a satisfactory system for overseeing how money is spent to improve our air quality. Our report finds that Departments are clearly failing to work together. The Government have promised some modest improvements, and I am sure the House looks forward to an update on that in the very near future, perhaps even today.

The Government response tells us that a consistent approach was taken to appraising the cost of air pollution, yet during our joint Committee hearings I was deeply concerned to learn that the then Exchequer Secretary to the Treasury, my hon. Friend the Member for Harrogate and Knaresborough (Andrew Jones), was not even aware of how much economic impact air pollution has on the UK.

It is clear that the Ministry of Housing, Communities and Local Government, the Treasury, the Department for Environment, Food and Rural Affairs, the Department for Business, Energy and Industrial Strategy, the Department for Transport, the Department of Health and Social Care and local authorities not only need to collaborate more effectively but need to collaborate, full stop.

[Dr Philippa Whitford (Central Ayrshire) (SNP)]

Does that not bring us to probably the single most important point we will touch on this afternoon, which is the need for health and wellbeing to be included in all policies and the need for us to get out of all the different silos?

[Neil Parish]

I could not agree more with the hon. Lady. Not only on air quality but in food policy and agriculture policy, health needs to be considered; it needs to be considered in all these things. This can be a beacon for the way forward, but we need much more co-operation between all parts of Government and local government. We would all agree that we have to be careful that the Government do not blame local government and that local government does not blame the Government.

The Government have told us that the Green Book guidance sets out what Departments should be doing and how they should be working together, but that has clearly not worked in the past, and we have received nothing to give us confidence that it will necessarily improve. Perhaps the Minister will be able to put me right.

The clean air strategy failed to include measures to improve road transport emissions. Emissions are being dealt with in a separate strategy, which demonstrates that the Government still operate in silos. I had hoped the Government would take more substantive measures to improve cross-departmental working.

[Andrew Selous]

I completely agree with the hon. Lady. In another guise, I co-chair the all-party group on cycling, so I absolutely get the importance of cycling and walking. They are not just good for our health and do not just cut congestion and pollution, but are good for our mental health, helping us to socialise and build community. There are so many reasons why what the hon. Lady said is absolutely right.

[Dr Whitford]

My home is on the west coast of Scotland, where I am lucky to have incredibly clean air, but when I am down here I normally walk or cycle to Parliament. If anyone else present suffers from asthma, they will know what a bad winter I have had, almost continuously since last November. It is no good telling people to get on their bikes or to walk when that then exposes them. We need to deal with the traffic to allow safe cycling.

[Andrew Selous]

I could not agree more. As someone who over the Easter recess cycled from my home to my constituency office along the busy A5, with juggernauts going fairly close to me, I completely understand what the hon. Lady says. We need safe cycling, and all the evidence shows that more people will cycle if it is safer. That is especially true for children going to school from all the new housing developments. When we build new housing, it is essential that we have safe cycle routes to the schools. That will result in healthier children, less childhood obesity and better communities.

Let me go quickly through the full list of health problems associated with poor air quality. It includes: premature birth; reduction in foetal growth; low birth weight; increased risk of death during the first year of life, particularly from respiratory illnesses; exacerbation of the effects of respiratory infections in young children; and effects on the normal growth of lung function during childhood. There is really shocking evidence that if a child’s lung capacity is damaged when it is young, it may never recover. From a social justice point of view, it is even worse, because it is the poorest kids who are breathing in the worst air. That is why this issue matters so much.

The list also includes cardiovascular disease, heart attacks, hypertension and stroke. Poor air quality also leads to chronic obstructive pulmonary disease; pneumonia; accelerated decline in lung function and lung cancer in adulthood; the development of early onset asthma, which the hon. Member for Central Ayrshire (Dr Whitford) mentioned just now, as well as exacerbating asthma in those already living with the condition; impaired cognition; dementia—a big Canadian study showed a link with dementia; and other neuro-degenerative disorders as well as type 2 diabetes, obesity and metabolic syndrome. I think that we can say that that is a pretty concerning list.

Public Health England is a very fine body, which I admire very greatly. Its chief executive, Duncan Selbie, does very good work, but we need more action from the organisation. It needs to be engaged in this issue. What it has done so far has been quite high level and quite strategic; it has not really come down to the level of the citizen, which is where we need it to be active.

One recommendation of the joint report of the Select Committees was that Public Health England should deliver an effective and appropriate campaign by this September, but Public Health England has told us that that is not possible in the timescale. That is despite the fact that the World Health Organisation has called this issue a public health emergency. I ask PHE to redouble its efforts on this issue and really try to get this information down to local levels so that people are, first, informed and, secondly, know what they can do to protect themselves best, and to stop being part of the problem and to start contributing to the issue.

I was pleased to see in the foreword to the Government’s 2018 clean air strategy, the statement by the Secretary of State that there would be a new goal that takes into account the World Health Organisation guidelines. There was also a commitment to primary legislation. I know that the Under-Secretary of State for Environment, Food and Rural Affairs, my hon. Friend the Member for Macclesfield (David Rutley), cares a lot about these matters. When he responds, could he please give us a little bit more detail on this issue? There are specific World Health Organisation guidelines on the amount of particulate matter—PM_2.5 —that we should not exceed on a daily basis. When the Government talk about taking into account the guidelines, I hope that they will go into that level of detail, bearing in mind what I said about the briefing from the British Heart Foundation about the increased risk of heart attack from elevated exposure to poor air quality just within a 24-hour period.

Winter pressure in the national health service is a huge issue that concerns every single Member here and I know the national health service is taking it extremely seriously as we head towards next winter. I have just been in the Upper Waiting Hall speaking to Dr Hugh Coe from Manchester University as part of evidence week, which is a very welcome intervention, as the top academics and scientists who know about these issues take the time and trouble to come down to Parliament to brief Members so that we are properly informed and can make good decisions on these matters. Dr Hugh Coe confirmed what the clinical chair of Bedfordshire clinical commissioning group said to me quite recently, which was that part of the increase in winter pressures, much of which is caused by older people going into hospital with respiratory problems, is from poor air quality. When we have cold weather in winter, the air is clammy and a bit foggy, which means that the pollution gets stuck in it. We breathe it in. It affects us more as we breathe it in. The same happens when it is very hot in the summer because the sun exacerbates the pollution. Again, I do not think that it is well known that there is this link between poor air quality, higher levels of respiratory problems and the winter pressures that we are all concerned about—a further reason for action.

My final issue is how we energise this issue at a local level. The Government talk about monitoring levels of air quality around schools. I would add old people’s homes as well. There are many other places where it is very important that we know the level of air quality. That information is really important to inform local residents, so that when they are looking to elect people to public office, either to Parliament or to local authorities, they can let them know how seriously they take this issue and the fact that they want something to be done about it.

Finally, we had a meeting on air quality and active travel in my constituency not so long ago. An older lady who had never smoked and who had led a pretty healthy life came up to me and said, “I am here today. I have just been diagnosed with chronic obstructive pulmonary disease. Where did that come from?” She had never smoked. The chances were, I am afraid, that she got it from breathing in poor quality air. That will greatly affect the last years of her life. Sometimes we talk in statistics and percentages, but I want to end my contribution with that one lady and the impact on her remaining years.

[Jim Fitzpatrick]

My hon. Friend is a well-known champion of rail freight transportation, and in his speech he made the case quite well for the construction of a national link. Were there to be a lower Thames crossing, obviously one would expect the authorities, local, regional and national, to get the biggest bang for the taxpayer’s pound, to ensure that we get the maximum benefit. I am sure that, as and when that debate takes place, my hon. Friend will be at the forefront of those advocating a rail dimension to that crossing.

[Dr Whitford]

On a point of interest, will these tunnels also have separate pedestrian and cyclist tunnels? Obviously, putting pedestrians and cyclists in the tunnel with traffic would be even worse than what are discussing, and why should they end up in a car because of the long route that needs to be taken by those on a bike?

[Jim Fitzpatrick]

The hon. Lady makes a very good point. The Minister may well be able to say what access there will be for both pedestrians and cyclists. We have two tunnels in east London. In the Blackwall tunnel there is no capacity for either pedestrians or cyclists, given the volumes of traffic and the narrowness of the verges. The Rotherhithe tunnel, which is even smaller and was constructed in the late 19th century, has restrictions on size, but the pollution down there is horrendous. One would therefore expect that new tunnels could have such capacity, separated from normal traffic, but I do not know whether that is in the construction plans. That is why I asked about public transport access. If that is included, pedestrians and cyclists can use those modes to negotiate the Thames, because it is a barrier in east London. As I said, half of London’s population lives in east London and people who want to get from south London to their jobs in Canary Wharf, the City and the west end find it really difficult to commute successfully.

[Iain Stewart (Milton Keynes South) (Con)]

It is a pleasure to contribute to this very welcome debate, and it was a great pleasure, too, to serve on the Joint Committee. My first point is about that Joint Committee: having inquiries that more than one Select Committee can participate in is a very welcome development. I urge the House to consider how more such inquiries might be facilitated. Earlier today we had a statement from the Health and Social Care Committee and the Communities and Local Government Committee on long-term care. Bringing expertise from a range of perspectives is very helpful and I would like to see more of it.

There are five brief points I would like to contribute to the debate. The first picks up on a point made by my hon. Friend the Member for Tiverton and Honiton (Neil Parish), which is that too often we have silo thinking in government and a lack of effective cross-departmental co-operation. It goes further than just policymaking, however. There has to be a change in culture in how schemes are budgeted for and evaluated for cost-effectiveness. Increasingly, we find that where expenditure might lie with one Department the benefit will accrue somewhere else, so it will not show up in the usual Treasury reporting of finances. For example, funding for a transport scheme would come from the Department for Transport or local government, but the Department of Health and Social Care might see the benefits because fewer people suffer conditions relating to poor air quality. I therefore urge the Government to start thinking a little bit more about that.

The second issue I would like to raise—I beg the indulgence of the House, but it is quite a techy point—is the Oslo effect. When we look at particle emissions from cars, too often we focus only on tail-pipe emissions. The Oslo effect occurs from invisible and odourless small particles going into the atmosphere as a result of brakes being applied, rubber tyres wearing down on the road, and even bitumen particles being thrown up when tyres hit the road. It may not sound a lot from any one individual car, but the cumulative effect, particularly in areas with high-sided buildings, can be substantial. Some studies show that only one third of particle emissions from cars actually comes from the tail pipe, with two thirds coming from those other sources.

This is a little bit counter-intuitive and I am certainly not arguing against the uptake of low-emission vehicles and moving to hybrid and electric cars, but like for like, those vehicles are heavier than their petrol or diesel equivalents. Therefore, the Oslo effect is exacerbated by those heavier cars. Manufacturers need to be encouraged to look at making cars as light as possible and to research other substances that could be used in place of rubber for brake pads and tyres. It also affects buses, which are by nature much heavier vehicles. I encourage Members—I declare an interest as chair of the all-party group on trams and light rail—not just to think immediately of buses as the best local transport solution. Trams may have a higher capital investment to begin with, but the savings they might deliver will accrue over a longer period of time. I also chair the all-party group on the Oxford-Milton Keynes-Cambridge corridor, which will be developing many new settlements over the next few decades. Each of those new settlements will have to develop local transport plans. This would be an ideal place to start looking at new and effective public transport solutions that are, as other Members have suggested, not car-centric, and at making it easier for people to walk or cycle to their destinations.

That leads me on to my third point, which is on cycling. I too have started cycling in London, from here to my home in London which happily resides in the constituency of the hon. Member for Poplar and Limehouse (Jim Fitzpatrick). I too cycle past the monitor that shows how many bikes go past each day. I absolutely encourage people to take up more cycling, but as the right hon. Member for Exeter (Mr Bradshaw) mentioned one of the biggest changes will come from electric bikes. There is a problem here. In my constituency in Milton Keynes, we have a network called redways, which are segregated from the main roads, for cyclists and pedestrians. At the moment, it is illegal to use an electric bike on them. I am trying to get to the bottom of whether this is a local authority decision or a more national matter.

[Dr Whitford]

As an electric bike owner—I tried not to take offence at the comments of the right hon. Member for Exeter (Mr Bradshaw) about electric bike owners—I know that there are two classes of electric bikes, one of which is allowed in cycle lanes and one of which is not. I wonder whether it is that difference about which the hon. Gentleman is hearing.

[Iain Stewart]

I am very grateful for that information. I was not aware that there were two classes of electric bikes, and I will certainly look into it. I imagine there is a great deal of confusion among people who own or might want to purchase an electric bike, and a bit more clarity might be helpful.

My fourth point concerns the use of new technology. We must always be looking into how new technology might be deployed to reduce transport emissions. I certainly do not want to reopen the debate about Heathrow, but time constraints prevented me from expanding on this subject in my speech on Monday. New technologies are available that will reduce emissions from the existing airport. One example is the TaxiBot, an autonomous electric vehicle which will take planes from the stand to the runway without the need to switch on the aircraft engines.

[Dr Philippa Whitford (Central Ayrshire) (SNP)]

One of the first big steps forward on air quality came after the great smog of 1952, when 4,000 people died within five days and 8,000 died in the following weeks. From that came the Clean Air Act 1956, which reduced pollution, particularly from coal, coming from industrial and domestic sources. However, in the 50 years since, traffic pollution has soared. Some 70% of UK towns and cities are defined as unsafe, with 37 out of 43 clean air zones failing on nitrous dioxides. There is a road in Lambeth that, every single year since 2010, has reached the number of breaches it is allowed in a year by the end of January.

The issue is not only about nitrous dioxides. Particulates have been mentioned—the 10 micrometres, and, more particularly, the 2.5 micrometres. These tiny particles get much further into the lungs and cause more damage. As the hon. Member for Strangford (Jim Shannon) mentioned, that damage particularly affects children and older people. Some 4.5 million children—a third of them—are exposed to unsafe levels. If they live near a busy road, they have twice the rate of respiratory problems. We are talking not only about asthma, the obvious one, but about reduced lung development and—if mothers were exposed during pregnancy—reduced brain development. Such things will lay down the quality of a child’s life before they are even born. Among older people, particulates increase the deterioration in lung function, as well as causing ischemic heart disease, increased rates of dementia and stroke.

Pressure in this country has developed only because of the threat of legal action from the EU last year; the can has been kicked down the road for years. The UK and eight other countries are facing legal action from the EU unless they get serious and radical. We would consider countries such as Germany and France, particularly Germany, to have good public transport. There is a particular need to invest in trains and trams—and in rural areas, in buses. Since transport was deregulated in the 1980s, Strathclyde in the west of Scotland has gone from having an integrated network of trains, tubes and buses to simply a free-for-all of ancient diesel buses all crowding the same roads. We have gone backwards in the past 40 years, and we need to go forwards. In rural areas, it is buses that are important. When it is just left to private companies, small villages quickly lose their bus services, which is not acceptable. We should be radical, and we should look at cities such as Copenhagen, which ripped up a ring road and turned it into a safe cycle route. We need things like that.

We heard from the right hon. Member for Exeter (Mr Bradshaw) that the cost of lung disease caused by poor air quality is £20 billion, yet we invest less than 5% of that amount in active travel infrastructure. As I said in an intervention, it comes down to health in all policies.

[Andrew Selous]

The hon. Lady has mentioned Copenhagen. Is she aware that 30% of all journeys in Amsterdam are by bicycle, compared with 2% in London? That came about through a real effort of political will many years ago to recreate the city to be fit for cycling.

[Dr Whitford]

I thank the hon. Gentleman for his intervention. My understanding is that 50% of journeys in Copenhagen are now made by bicycle. But this does require investment in infrastructure.

The hon. Member for Poplar and Limehouse (Jim Fitzpatrick) mentioned a new tunnel at Silvertown. The Clyde tunnel was finished in 1963 and it consists of two circular tunnels, with the road deck about a third of the way up and room for cyclists, pedestrians and ventilation underneath. That was back in the ’60s. We need to make sure we are not investing in hugely expensive tunnels that go against active transport.

It is about health in all policies. Decisions are made in silos, even in this place. We make decisions on different days that counteract each other, which is frustrating. If we had physical health and mental wellbeing as an overarching principle like human rights, people sitting in our town halls and here would focus not on cars, on how they drive and how they park—that is the focus in our towns and cities at the moment—but on people. We would design safe, segregated cycle routes, and we would have much wider pavements on which children could ride their scooters, and on which people with prams or wheelchairs would not be crowded out—people would not need to step into the roadway to pass them. When we have such glorious and, in Scotland, very unusual sunny weather, it would also create an environment in which cafés could be outside. People would walk around their town centres and meet their neighbours, which would contribute to a sense of belonging and community. I would love to see health and wellbeing as the driving force in every decision made by town halls, national Government and Westminster on how we design our towns and cities.

[Mary Creagh]

Will the hon. Lady give way?

[Dr Whitford]

I have finished, I am afraid. Sorry.

--- Later in debate ---

[David Rutley]

If the hon. Lady will let me, I would like to answer her question. Only six other countries in the world are moving more quickly than the UK on ending petrol and diesel, and the UK is moving faster than almost every other country in the EU, as well as many other countries such as the US and Australia.

The £3.5 billion investment also includes £1.2 billion of available funding for the first ever statutory cycling and walking investment strategy. I know that that has been raised by a number of Members who have talked about what we can do to improve the take-up of cycling and walking. I think that, perhaps, there has been an over representation of the cycling lobby today. As a former member of the mountaineering all-party parliamentary group, the pinnacle of APPGs, we need to speak up for walkers as well. I know that the hon. Member for Nottingham South (Lilian Greenwood) fully agrees with me on that important point.

[Dr Whitford]

Does the Minister recognise, however, the disparity between the cost to the Government through ill health and the amount that is being spent on active transport, be it cycling or walking?

[David Rutley]

There is more that we need to do, but the £1.2 billion funding in the cycling and walking investment strategy is a first important step, and we need to build on that—no question.

A number of important issues have been raised throughout the debate, and I will address some of them in the time remaining. One issue that has been highlighted is that of what we can do to help raise people’s awareness of the health challenges around air quality. There were important contributions on this topic from my hon. Friends the Members for Erewash (Maggie Throup) and for South West Bedfordshire, the right hon. Member for Exeter (Mr Bradshaw), and the hon. Members for Wakefield, for Brentford and Isleworth (Ruth Cadbury) and for Strangford (Jim Shannon). Through the clean air strategy, we are committed to a national information campaign to raise awareness of the dangers of air pollution. We will introduce a personal messaging system to ensure that those who are most at risk receive the information that they need about pollution risks. Public Health England is currently reviewing evidence of the effectiveness of different interventions, and will report its findings to Ministers later this year. This will include advice on the factors affecting behaviour change around air quality.

The Committees have called for a new clean air Act. As announced in our clean air strategy, we will set out new primary legislation to secure a more coherent legislative framework for action to tackle air pollution.
