Improving Air Quality — House of Commons, 2018-06-28
Topic: Environment
Lilian Rachel Greenwood (Labour, Centre-left): 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 PM2.5. 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.
