Improving Air Quality

Rupa Huq Excerpts

Thursday 28th June 2018 Commons Chamber

[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.

[Dr Rupa Huq (Ealing Central and Acton) (Lab)]

The hon. Gentleman is making some interesting points about the public purse and joined-up thinking between Departments. He says that road emissions are not included in the clean air strategy. Does he have any comment on aviation? Does he agree with some of us on this side that it seems lamentable that, when 9,000 Londoners a year are dying from toxic air, we have just taken a decision to approve the expansion of Heathrow airport? Willie Walsh, from the parent company of British Airways, said the decision is outrageous—he actually called it BS, but I will not repeat that word here because it is unparliamentary. He said that the cost does not stack up.

[Neil Parish]

I understand the hon. Lady’s concern, but I will not venture into the airport air pollution problem. A lot of the air quality, certainly on the ground, has a lot to do with the extra traffic going in and out of the terminals. That also has to be dealt with. There is a lot to be done, but I do not want to get into a huge debate about the runway at Heathrow.

[Lilian Greenwood (Nottingham South) (Lab)]

It is a great pleasure to follow the hon. Member for Tiverton and Honiton (Neil Parish), and I look forward to the speeches by my fellow Select Committee Chairs, my hon. Friend the Member for Wakefield (Mary Creagh) and the hon. Member for Totnes (Dr Wollaston).

I am afraid that this is a rather sorry tale of inaction and buck passing. Fault lies not with one party but with successive Governments. The efforts so far have been inadequate and have been characterised by a lack of urgency. We know the problems that poor air quality causes. It affects our health and our environment and, as has already been said, as many as 40,000 people die prematurely each year as a result of poor air quality. The elderly, the unwell and the economically deprived are those most likely to be affected. The Government estimate that poor air quality costs the UK economy £27.5 billion a year.

We also know where the problem occurs. Key pollutants include nitrogen dioxide and fine particulate matter, known as PM_2.5. More than 85% of air quality zones in the UK—37 out of 43—exceeded EU nitrogen dioxide limits in 2016. They should have been compliant in 2010, and the Government think it will be 2026 before all 43 zones in the UK are compliant. The World Health Organisation tells us there is no safe level of exposure to fine particulate matter.

We know what causes poor air quality. It comes from several sources: industry, agriculture, homes, businesses and transport. Progress has been made, but it is stalling, and we are in breach of our legal obligations. Road transport is responsible for about 80% of nitrogen oxide concentrations at places in the UK that exceed legal limits, with diesel engines a significant contributor. The number of cars and vans on our roads continues to rise, and congestion has worsened, which increases pollution in itself. Although diesel cars have become less popular since the VW scandal was uncovered in 2015, for more than a decade before that the trend was in the opposite direction.

Transport also generates a significant proportion of particulate matter, from both combustion, and wear on tyres and brake pads. The Government have largely relied on cleaner vehicles to solve the problem, and limits on emissions, which are gradually tightened with each iteration of the euro standards, have helped us make some progress but not enough. Real world emissions have not fallen as promised, and renewing the fleet could take 15 years or more. Policies to accelerate this process, such as scrappage schemes, may be needed. The science, historical evidence and impact are clear, but we still have not taken the action that is needed. Three times the Government’s strategy has been found wanting by the courts, and the UK faces large fines by the EU Commission, along with other countries, for not bringing air quality within legal limits. We know the solutions that are needed, so it is shocking that successive Governments have failed to take the necessary action.

Nationally and locally there are examples of good things happening. In my own city there has been considerable investment in public transport, with major extensions to our tram network, and that was supported by the coalition Government. Last year, Nottingham’s municipal bus company introduced new biogas buses, and work has begun to retrofit its entire fleet of diesel buses by autumn 2019. Last week, on Clean Air Day, the city council launched an anti-idling campaign, mirroring similar action in other towns and cities across the UK. As I have said, the Department for Transport has supported the development of low emission buses and taxis, has regulated maritime emissions, is supporting low emission vehicles and alternative fuels, and has lead work on the development of real driving emissions standards.

So what has gone wrong—why have we not solved this problem? The first issue we found in this regard was collaboration. That is not a problem that can be fixed by central Government or local government alone—they need to work together. At present, action is too fragmented, lacks clear leadership, and is not properly costed or resourced. There are no fiscal measures that support long-term behaviour change in a meaningful way. Local authorities are already responsible for meeting air quality limits but find it difficult to make changes, partly due to lack of resources, but partly because the changes needed are politically unpalatable. Our joint Select Committee report called for ambitious, co-ordinated, cross-departmental action. Sadly, the Government’s new draft strategy says almost nothing about emissions from cars, and we are still waiting for the Department to publish its strategy “Road to Zero”. That simply does not seem very joined-up.

It is vital that we encourage the uptake of clean technologies and remove the most polluting vehicles from our roads, but the Government rejected a more ambitious target for ending the sale of petrol and diesel cars before 2040. Today, Lord Deben, chair of the Committee on Climate Change, echoed our call in the drive to meet targets on carbon emissions. There are rumours that the “Road to Zero” will water down the commitment to end sales of diesel and petrol cars even further, and I hope that this latest intervention will prompt Ministers to think again.

The Government also need to accelerate the switch to ultra low emission vehicles, and that requires a network of charging points, particularly for rapid charging, and a strategy for on-street residential charging.

[Dr Huq]

Does my hon. Friend agree that in London we have made significant progress, with the current Mayor bringing forward the ultra low emission zone and with the proposed toxicity charge? However, sadly, a lot of this seems to have been undermined by this week’s decision—I know she voted the right way—to have an extra runway in Heathrow. People in west London are lamenting that, and I regret that a lot of the good work in her report was ignored by the Government’s national policy statement.

[Lilian Greenwood]

I thank my hon. Friend. She rightly says that a lot of work has been done in London, yet it still faces a huge challenge on air quality. That is one reason why our Select Committee report on the airports NPS calls for extra safeguards on air quality. Obviously, Parliament did vote for the NPS and the Secretary of State has now designated it, but it is essential he keeps his promises on air quality.

It is also vital that the public sector leads, demonstrating what is possible. The Government could set dates by which their car fleet will all be ULEVs. Local authorities, the NHS and other large public bodies could do the same with their fleets. It is not just on road transport where the Government are less ambitious than they might be. The decision to row back from electrification of our railways in favour of bi-mode trains has worrying implications for air quality, carbon emissions and noise. Of course, our Committee has also published a report on rail investment today. Those look more like decisions taken in isolation than decisions taken under the umbrella of an overarching strategy.

There is a danger that the Government rely too heavily on new technologies to solve our air quality challenges, placing too much emphasis on cleaning up road vehicles and not enough on reducing the number of vehicles on our roads. Improving public transport and encouraging active travel should lie at the heart of any clean air strategy. Our four committees concluded that the Department for Environment, Food and Rural Affairs and the Department for Transport must work closely with local authorities to ensure that councils introducing clean air zones receive the support they need to implement complementary measures that encourage car drivers to switch to public transport and active travel, as well as increasing the take-up of electric vehicles. Yet modal shift and active travel—walking and cycling—hardly get a mention in the Government’s draft strategy.

Investment in low emission buses is great but the value of such investments is magnified if local authorities also take steps to encourage motorists to opt for buses rather than making journeys by car. The latest passenger statistics show that bus patronage is falling and rail passenger numbers are also down. It is too early to say whether that is a blip or the start of a trend, but the Government should be concerned. Is the policy response in line with the strategy the Government tell us they want to have? Well, not really—the cost of rail and bus travel are rising faster than the cost of motoring. The Government’s own assumptions appear to show that, as things stand, they accept that their policies will not deliver a financial incentive to encourage or support modal shift. Without some action, whether on fuel duty or charging zones, efforts to tackle congestion or improve air quality are less likely to succeed. It would be helpful if the Government were to articulate more clearly than they have what they want to achieve on modal shift and how they will deliver that, and I look forward to hearing the Minister’s comments today.

The Government also need to create a framework in which local authorities have the resources and powers they need to act. The new expectations on councils on air quality come at a time when they are already facing huge funding pressures. The Government must provide all local authorities breaching nitrogen dioxide limit levels with access to the financial resources they need to tackle them. Responsibility for providing those resources should not lie only with the public sector: following the principle that the polluter should pay, the private sector should be asked to contribute to a clean air fund. As hon. Members have said, Volkswagen and other car manufacturers that cheated emissions tests should be held to account. Our Select Committee has repeatedly raised this issue with Ministers and the lack of action is deeply disappointing.

Policies and action at local level also need supporting national polices and a public debate that makes it less difficult to implement things that may not be universally popular. Our ambitions for cleaner air, with the associated public health and environmental benefits, cannot succeed without action by local authorities, businesses and communities. The sustained improvements we have seen in air quality in the past can be continued only if Government action—legislative, policy, taxation, and spending—is co-ordinated and working in tandem with other players. By failing to act in a joined-up way, the Government are not just undermining their air quality strategy; they are missing opportunities for synergies that would help deliver on other policy goals. For example, many of the policies needed to tackle urban congestion could also help to improve air quality, and tackling both could have a positive effect on the local and national economy. A significant increase in active travel could make a difference to policies on tackling obesity, improving mental health and building better communities. Action on air quality could help to reduce carbon emissions. The realisation of the wider benefits cannot be left to happen by chance.

Action on poor air quality is long overdue. There are things we can do—this is not a problem without a solution—but if the Government do not show leadership, nothing will change. We have passed the point where more of the same will do the job; the courts have made that clear. Bold, ambitious and innovative polices are needed to create the right framework for action—a framework within which national policies support and encourage the right kinds of action at a local level. The Government have launched a consultation on their clean air strategy, but its lack of focus on transport emissions looks complacent, falling well short of what we recommended in our joint report. I hope that Ministers will heed our calls today and redouble their efforts.
