Heathrow Expansion: Air Quality

Ruth Cadbury Excerpts

Tuesday 22nd November 2016 Westminster Hall

[Dr Tania Mathias (Twickenham) (Con)]

I beg to move,

That this House has considered the effect on air quality of proposed Heathrow airport expansion.

It is a pleasure to serve under your chairmanship, Mr Hollobone. As you and the Minister are aware, I have spent much time in Parliament on the issues of Heathrow and Heathrow expansion because many of my constituents in Twickenham are concerned. It is therefore a great disappointment to me that the Government recently decided to support Heathrow expansion, and I reiterate that I am still firmly and utterly opposed to that decision.

[Ruth Cadbury (Brentford and Isleworth) (Lab)]

I congratulate the hon. Lady, my constituency neighbour, on securing this debate. I alert the House that many MPs for constituencies in and around Heathrow airport have constituents who are worried about the implications of the proposed expansion and about air quality, which is increasingly important locally.

[Dr Mathias]

I thank the hon. Lady for making that important point, as this not only affects Twickenham. Four councils are currently taking the Government to court over air quality because of Heathrow. Air quality is an important concern for many people.

The people, like the hon. Lady, know that Heathrow is not deliverable on many levels, including cost, noise pollution and the upcoming legal challenges, but the insurmountable challenge, and the reason I secured this debate, is air quality. The Minister will know that air quality is a major and increasing concern, and he may recall that in January 2016 I asked the then Prime Minister about the shocking news that the annual legal limit for nitrogen dioxide had been breached in London by 8 January. A map of nitrogen dioxide levels across London and Heathrow shows high concentrations in central London and Heathrow. Nitrogen dioxide, of course, affects the lungs, particularly in people with asthma or bronchial conditions, and decreases lung function growth in children.

Perhaps of even more concern is particulate matter. I am sure the Minister is aware of the World Health Organisation’s comments on particulate matter, which affects more people than any other pollutant. Although I will be talking about the legal limits for PM_2.5 and PM₁₀, I remind him that the WHO has said that for PM_2.5

“no threshold has been identified below which no damage to health is observed.”

There is no safe level but, just like for nitrogen dioxide, London breached the annual legal limit in the first few months of this year. Forty cities in the United Kingdom have already breached the annual legal limit for PM_2.5, and London is in the top six. PM₁₀ is also of serious concern. Only 11 cities in the United Kingdom breached the annual legal limit in the early part of this year, and London is in the top four.

Particulate matter contributes to fatalities from strokes, heart disease, lung cancer and acute and chronic respiratory diseases. The cost in human terms is that 9,000 deaths a year in Greater London are attributable to nitrogen dioxide or particulate matter, which are just some of the air pollutants. Four thousand deaths in 1952 gave rise to the Clean Air Act 1956. Now we have more than double that number every year, and the Government are not doing enough.

What concerns me is that, within just over a week of the Government’s being found guilty in the courts of not having an adequate plan to address air quality, they decided to approve Heathrow expansion. The expansion will involve perhaps 50% more planes. The Minister might say that it is not the aircraft but the cars that are adding to the air pollutants, but Heathrow lies near the M4 and the M25, two of the country’s most congested motorways. He will also know that, with nearly 250,000 more flights planned, there will be thousands more passengers and staff, and they will not be walking to and from Heathrow airport.

The number of cars will increase, and I do not agree or accept that electric cars will be the answer. There are 11 million diesel cars in the United Kingdom, and they will not be scrapped and replaced in time for the proposed Heathrow expansion. I do not want to hear that putting on facemasks will protect us from particulate matter, because the British Lung Foundation says that there is no evidence that that will help.

Heathrow implicitly acknowledges the risk to air quality. I am sure the Minister has a well-thumbed copy of the Airports Commission report, and page 225 states that £799 million will be spent on car parks at an expanded Heathrow. That will increase air pollutants, which are already breaching legal limits. Heathrow Airport Holdings Ltd will argue about how much it wants to spend on surface access—that is one argument—but nobody who favours Heathrow expansion denies that surface access will increase, which means more road trips and more pollutants.

[Ruth Cadbury]

Will the hon. Lady give way?

[Dr Mathias]

I will in a while, if I have time.

Heathrow airport prides itself on being a leading cargo airport. Again, cargo and freight are not coming to and from Heathrow in an electric car or on a horse and cart. My question to the Minister is simple: if the Government support Heathrow expansion, how will they get air quality within legal targets? I have asked two Prime Ministers, two Secretaries of State for Transport and a Minister from the Department for Environment, Food and Rural Affairs how they can expand Heathrow airport without increasing air pollution. Thus far, I have been assured that it will happen, but I have not been told how. I hope that today, at the sixth time of asking, I will be told.

Howard Davies spent years and millions of pounds of taxpayers’ money on his commission’s report, and he said on page 307 of the Minister’s well-thumbed copy that

“an expanded Heathrow Airport must be contingent on acceptable performance on air quality.”

Howard Davies said that that was needed but, again, the report did not specify how it would be achieved. We need airport expansion, but it must be in a place where the legal limits for air pollution have not been breached.

[Mr Hayes]

I will give way briefly to the hon. Member for Brentford and Isleworth (Ruth Cadbury).

[Ruth Cadbury]

I thank the Minister for giving way. Last week at Transport questions, I asked a question about an issue that concerns my local area, which is the proposed expansion of the M4, which, so far as I can see, would be needed if the third runway is given the go-ahead. Will the Minister comment on the impact on air quality of a tunnel coming up either in Brentford or Chiswick?

[Mr Hayes]

Yes. Among my many responsibilities, although I know that Members in this Chamber think that they are too few, are big roads, and the M4 is indeed a big road. However, it is important to point out that in any expansion that takes place at Heathrow, a range of transport connections would be considered. I know that Heathrow is considering how people would get to and from the airport. That will not just be by car. The hon. Lady will know that about 45% of people currently make their journey to and from Heathrow by private vehicle, but that number is not fixed in stone. One would hope that—indeed, I would expect it to be so as part of this package—all kinds of innovative solutions will be delivered as to how people can get to the airport efficiently.

Therefore, I do not want to prejudge that issue and I certainly would not want either to say anything that contradicted the answer that the hon. Lady received last week, because the question then was not posed to me; I think it was posed to the Secretary of State. I reassure the hon. Lady that we are broad-minded about the means by which people get to and from Heathrow and the effects that might have on local people.

Let me make my last three points, because I promised 10 points and so far I have delivered only seven. The Government have also made it clear that we must tackle noise and I know that my hon. Friend the Member for Twickenham is also concerned about this. We will also meet our obligations on carbon. On noise, Heathrow Airport Holdings Ltd has committed to a ban on scheduled night flights of six and a half hours, more predictable periods of respite for communities and new and binding noise targets.

Ninthly, the Government’s announcement was just the beginning, as I said, of the process, as the preferred scheme will now be subject for consultation through a draft airports national policy statement that will follow in the new year. Of course, that is something to look forward to after the excitement of Christmas.

Finally, it is important to point out—I know that my hon. Friend is very conscious of this and I thought she deserved an answer on it—that the Government accept the recent High Court judgment that more needs to be done to improve the nation’s air quality. That does not apply simply to airports; I am looking at a range of transport modes, as she will doubtless appreciate. I can tell her that the Government will produce a revised plan by 31 July 2017 and my team in the Department for Transport are beavering away and working with other relevant Departments to make sure that the plan meets all the necessary requirements.
