Children’s Health: Vehicle Emissions

Baroness Randerson Excerpts

Tuesday 11th June 2019 Lords Chamber

Asked by

[Baroness Randerson]

To ask Her Majesty’s Government what steps they intend to take to protect children from harmful vehicle emissions.

[Baroness Randerson (LD)]

My Lords, I am very pleased indeed to have the opportunity to help raise the profile of this issue which is, in my view, a major child healthcare crisis. It is particularly dangerous because emissions are an unseen danger. I am grateful to all noble Lords participating in this debate. I want to stress that new facts are still emerging as scientists and the medical profession become more aware of the complexities of the physical impact of emissions. I also want to thank the numerous organisations working in this field which have taken the trouble to brief me; I will refer to some of them in my speech.

It is estimated that there are around 40,000 excess deaths every year as a result of air pollution. Many of these are older people, but some of them are children. The effects of air pollution on children’s physical development continue throughout their life, with a cost to the NHS estimated at £20 billion. Some of you may be aware of the sad case of little Ella Kissi-Debrah from south London who died following an asthma attack. The post-mortem revealed the shocking state of her lungs. Her mother is now working to get air pollution accepted as a cause of her death and was recently granted a new inquest.

Some 80% of the pollution we breathe in urban areas is caused by traffic. It comes in two forms: nitrogen dioxide and particulates. Nitrogen dioxide comes from diesel. In the early years of this century, the then Labour Government mistakenly encouraged the switch to diesel in order to reduce the CO₂ emissions associated with petrol. We still live with this mistake, with many older diesel cars on our roads. Newer diesel vehicles are cleaner, but the Volkswagen diesel scandal undermined public confidence. All vehicles, even electric ones, produce particulates resulting from the wear and tear of tyres on the roads. Tyres are about 50% plastic, so that means we are breathing in minute particles that get into our lungs and bloodstream.

Children are particularly at risk, as explained by UNICEF in its sobering report The Toxic School Run. It explains that children breathe faster than adults, tend to take in more air relative to their body weight and spend more time outside. When they walk or are pushed in a buggy, they are at a lower level, near the exhaust fumes. One might imagine that the answer is to put them in the back of the car and take them to school, but emission dangers are 30% higher in the car.

The most urbanised and, therefore, most polluted areas are also those with larger populations of children. We tend to move to leafier suburbs as we get older. Inner urban areas are also in general the most economically deprived, so pollution pushes down further on other health inequalities. Emissions affect the development of children’s lungs and cause irreversible damage. They aggravate and can cause asthma, and 1.1 million children in the UK have that disease. It affects brain development and in later life causes not just lung disease but heart disease, cancer, strokes, and is even linked with dementia. From fetus to old age, it impacts on our health.

The scale of the problem is that 2,000 schools and nurseries are situated in areas with unsafe and illegal levels of air pollution. Some 4.5 million children are at risk across 80% of the UK. Britain has been in breach of EU emission limits for nine years and the Government have been taken to court three times.

With perfect timing, last night Channel 4 devoted its “Dispatches” programme to the impact of emissions on pupils at a south London primary school. That area breaches annual EU limits for exposure every month. Fifty children were tested before and after undertaking a series of simple measures to reduce pollution exposure. The first tests showed particles in their bodies at a very high level. Green screens were erected around the school, children walked to school instead of being driven, quieter routes were chosen, plastic nets were placed over windows and air filters installed in classrooms. It led to a dramatic fall in the level of pollution found in their bodies and the level of pollution in the playground fell by 53%.

The cost of these measures was £30,000—not a major financial outlay. That illustrates my point: the Government need to take some big strategic approaches and manufacturers need to take technological developments, but there is so much we can do at an individual level, both in local communities and, indeed, at school level, as well as at council level. Some of these measures even save money.

Looking at the big picture, I am very glad the Government have a clean air strategy, but it is rather unambitious. It hives off the lion’s share of responsibility on local authorities, whose funding has been hollowed out. Remember, too, that it is EU standards that the Government have failed to meet, so Brexit adds another layer of uncertainty. As we watch the auction of promises between the 10 candidates for leader of the Conservative Party, I regret that there has been very little talk of the environment. In future, the Government might be tempted to abandon EU standards.

We need to speed up the switch to electric or hydrogen vehicles. The Government’s target of 2040 is way too late. In fact it is meaningless, because the whole industry is moving faster than that; 2030 would be a more effective date. We need a new clean air Act—remember that the last was extremely successful. It should be based on WHO guidelines, with legally binding targets, including for particulates. Our legal limit in Britain for particulates is twice the WHO recommended level.

There is a range of other government actions that could be taken, such as vehicle excise duty reform to encourage us to buy lower emission cars. I would love the Government to lead by example. Apparently, 2% of the vehicles in the Department for Transport’s fleet are electric. All branches of government should be doing much better than that, as Royal Mail intends to—they are doing a lot to electrify their fleet. We need stronger leadership from the Government to develop electric vehicle charging points, carefully targeted scrappage schemes for those on lower incomes and to help bus companies to retrofit old buses. It is a debate for another day, but the Government need a proper bus strategy to encourage the public out of their cars and back on to buses, tackling both congestion and emissions, and linking in with train services.

Because pollution is a hidden danger, there is very little public understanding about it, so we need a strong public health campaign. We need people to understand where the dangers lie and what they can do to avoid them. Local authorities should be given additional powers—for example, to use the planning system to ensure that new developments include safe walking and cycling to school routes, and that new schools do not encourage car use rather than walking. I would recommend ring-fenced funding for active travel schemes, as part of a national strategy, delivered locally, to encourage the healthiest way of all to school.

The number of people fined in the last 10 years for idling their engines outside schools is in the tens—not the hundreds or the thousands. Local authorities need more flexible powers to discourage people from doing that. There are some very good examples of schools running local, children-based campaigns with the parents, to discourage them from doing that. New clean air zones need to be funded locally. Traffic exclusion zones around schools, regular air quality monitoring, installing roadside signs to test and to warn when air quality is poor—these are the sort of simple measures in and around schools that do not cost a vast amount of money, but which are very effective.

I hope I have illustrated that it does not have to be like this. Surely in our rich and well-developed country, none of us could imagine knowingly allowing our children to risk illness and death by drinking polluted water. Well, neither should we allow children to be exposed to polluted air. We now know enough about the effects of emissions, how harmful they are and how to prevent them. Children should have a legal right to clean air.
