Lords ChamberMy Lords, I have my name on several of these amendments—namely, Amendment 150A and Amendments 156A to 156M—and I support the others in this group.
Following the 1952 smogs, the Clean Air Act, as we have already heard, came in in 1956 and cut coal smoke from homes. In the 1970s, the output from power stations was high in sulphur dioxide, causing acid rain. Now, there is a lot of research to show that a major source of different particles is exhaust fumes from burning liquid fossil fuels. In 2018, the World Health Organization recognised the effects of these ultra-fine particulates, which are implicated in about 8.8 million excess deaths—around 13% of all deaths globally.
The report The Lifelong Impact of Air Pollution, from the Royal College of Physicians, has shown that it costs £20 billion in the UK alone, through 40,000 deaths per annum, ranging from heart disease, asthma, chronic obstructive pulmonary disease, lung cancer, diabetes and dementia—which are all linked to atmospheric pollution.
Our death rates from asthma are the worst in Europe. Three people die every day in the UK from asthma. It costs us £1 billion a year and there are more than 5.5 million people having treatment for asthma now. People with a genetic predisposition to asthma living by main roads have worse outcomes. It does seem there are some groups in the BAME community who have a particular genetic predisposition to a type of asthma that is particularly liable to lead to death. There have been 12,700 asthma deaths in England and Wales since 2010.
The role of atmospheric pollution was shown clearly and graphically by Professor Stephen Holgate to map against Ella Adoo-Kissi-Debrah’s very severe asthma attacks, including her final and fatal attack, with spikes of nitrous oxide and particulates corresponding clearly to her severe exacerbations. These particulates from fossil fuel exhausts also cross the placenta into the foetus, resulting in a higher incidence of asthma and impaired brain development.
This means it is essential that we tackle this on every front to come into line the WHO guidance as a minimum. We cannot tolerate continuing to allow particulate air pollution, and we must harness positive behaviour and change behaviours. The impact, in fewer heart attacks, strokes and deaths from asthma and lung cancer, would be phenomenal. That is why I added my name to Amendments 156A to 156M, because there is a need to give local authorities the power that they need to protect their own populations.
I will turn briefly to speed restrictions, so comprehensively introduced by the noble Baroness, Lady Sheehan. I endorse every point that she made. Let us not forget that 20 million children have their homes and schools in areas of high air pollution, particularly from traffic.
The report The State of the Evidence on 20mph Speed Limits, by Dr Adrian Davis from Bristol, provides a comprehensive review of the literature. Dropping the speed limit from 30 mph to 20 mph decreases particulates from petrol and particularly from diesel, as well as decreasing nitrous oxide and CO2 emissions from diesel cars. Road traffic is responsible for 80% of particulate production, and diesel produces tenfold more particulates than petrol. When children are sitting in a car in a traffic jam, their exposure is even higher because cars draw in the surrounding air, which is laden with exhaust from other vehicles.
It has been estimated that a cut from 30 mph to 20 mph on urban roads would result in a drop of over 115 deaths from particulates alone, quite apart from the lower death rate in accidents. When traffic is less aggressive and moving more smoothly in urban areas, there is almost no significant delay in getting somewhere but the whole driving experience is calmer and safer. I should declare that I experience this, because I live in the Cardiff pilot area that has dropped from 30 mph to 20 mph and the benefit is tangible. I hope that the Government can support these amendments.
My Lords, I declare an interest as one of the 5.5 million people with asthma. In winding up this debate on behalf of these Benches, I first thank the Minister for the fact sheet about the air pollution measures in the Bill. It certainly shows willing, but it also falls short of what we would wish to see and gives rise to a number of questions. In particular, why do the Government remain to be convinced and want a whole lot more consultation about the feasibility of the pollution reductions that we are seeking, despite confirmation from many experts that these things can be achieved and would be accepted by the public?
I hope that the noble Baroness, Lady Jones of Moulsecoomb, will forgive me for focusing on the amendments of my noble friends, but we also support her amendments, which very much overlap with ours. I support Amendment 150A, moved by my noble friend Lady Sheehan. If the Government were to support Amendment 150A, not only would our air be cleaner and healthier but injuries and lives would be saved because of the reduced speed.
As my noble friend said, electric cars reduce NOx and CO2 emissions, but they still produce NEE particulates from tyres and brakes. A default 20-mph limit would reduce these particulates as well as noise, and injuries and deaths through accidents. Children in particular would be protected from accidents and from organ damage caused by particulates. Will the Minister note what my noble friend said about how people in disadvantaged demographics are more likely to live in areas with high levels of PM2.5?
I accept that local authorities can already designate roads with a 20-mph limit, but my noble friend’s amendment would make it much easier for them, as 20 mph would become the norm in relevant streets. Local authorities are already strapped for cash and have been given additional responsibilities through this Bill, such as imposing civil sanctions where once there were criminal offences, liaising with air quality partners and other matters. However, it is important to consider how legislation could help them to carry out some of their many responsibilities.
There is already considerable support for this measure in Wales and Scotland. In May, as soon as we were allowed, my husband and I went to Scotland for a short break. We noticed how many villages now have 20-mph limits. The traffic moved smoothly, there were no jams and people moved around safely. It was a good example of what can be done and there are similar examples in Wales. If the Minister will not accept this amendment, how do the Government intend to encourage 20-mph zones?
In her Amendments 151A and 151B, my noble friend Lady Randerson wants local authorities to “raise their game”, to be more ambitious about monitoring air pollution and, critically, in publicising the levels specifically in sensitive areas to encourage a change in behaviour, and to be funded to do so. This is particularly important for the future health of our children as well as adults. I hope that the Minister looks at my noble friend’s proposals very seriously. I note the measures already taken, but the fact remains that awareness of pollution levels is low. There may be websites and air quality alert systems, there may be leaflets about smoke control areas and recycling household waste, but the most effective information is gathered and distributed locally, as the noble Lord, Lord Lucas, said.
I welcome initiatives such as the one in Liverpool funded by the air quality grant, which involves children in monitoring the area around their school. I am sure that they would be exerting pester-power and encouraging their parents to walk or cycle them to school, and certainly not to sit outside in their cars at the end of the school day with the engine running, as I have seen outside my local school. However, we need more. Can the Minister explain why we do not need my noble friend’s amendments?
I turn to Amendments 156A to 156M in the name of my noble friend Lord Tope. I welcome the Government’s acknowledgement of the risk to human health presented by poor air quality. That is a major step in the right direction. As we have heard, local authorities have a statutory duty to reduce emissions in their area, but even the Government have recognised that they do not have sufficient powers to take effective action to achieve such reductions, hence some of the government changes in this Bill. Public and government attention has focused mainly on the need to cut emissions from vehicles, but non-road pollution is a major problem, too often ignored, also emitting nitrogen oxide particulate matter that provides a major public health hazard, as we have heard from the noble Baroness, Lady Finlay. As we make improvements in reducing emissions from vehicles, we must shift our focus to these other sources of pollution too, which is what these amendments do.
We heard from my noble friend Lord Tope about the negligible impact on PM2.5 of the significant reduction in transport activity in London during the pandemic. This highlights the importance of reducing non-road emissions as well as speed, as emphasised by my noble friend Lady Sheehan. These amendments introduce a series of new clauses which would give local authorities additional discretionary powers. Through Amendment 156A, they would be able to designate an area as an air-quality improvement area. If the air quality in that area exceeded WHO air quality guidelines, the Secretary of State could set limits for emissions for a range of these pollutions and equipment. The amendments provide for offences for users and installers who break the regulations, and certain legitimate defences. There are also powers to time limit the use of certain plant which might have a legitimate use in case of a power cut, and to require users to provide relevant information.
