Children’s Health: Vehicle Emissions

Baroness Blackstone Excerpts

Tuesday 11th June 2019 Lords Chamber

[Baroness Blackstone (Ind Lab)]

My Lords, I declare an interest as the chairman of the board of trustees of the British Lung Foundation. I expect that, in replying to this debate, the Minister will refer to the clean air strategy, published earlier this year. I acknowledge that much of this is a considerable step forward over what went before. However, there now needs to be greater urgency in implementing the government strategy for reducing air pollution, particularly those parts which affect children. I would like to hear from the Minister the Government’s timetable for making progress on preventing further damage to our children. We cannot allow more premature deaths as a result of air pollution, whether through lung and heart disease, stroke or cancer. Progress must be rapid. The damage being done is horrendous: around one in three children in the UK is growing up in areas with unsafe levels of air pollution.

I reinforce what the noble Baroness, Lady Randerson, has said. Toxic air disproportionately affects children from the moment they are conceived and through their early lives as their bodies grow and they go through periods of critical development. Air pollution exposure during pregnancy is linked to low birth weight and premature birth. Children also tend to spend more time outside, where concentrations of air pollution from traffic are generally higher. As the noble Earl just said, when small children are walking or in a pushchair, they are often at the height of vehicle exhausts, meaning that they breathe in higher concentrations of pollutants. Breathing polluted air can cause irreversible damage to children’s growing lungs. There is increasing evidence that air pollution not only aggravates asthma in children but causes it.

Air pollution worsens existing health inequalities. People living in the poorest areas are often the most exposed to pollution, thus reinforcing unequal health outcomes. It also contributes to health inequalities later in life. Children living in highly polluted areas are four times more likely to have reduced lung function in adulthood, leaving them with lifelong health challenges. Some 1.1 million children—one in 11—are receiving treatment for asthma. For these children, exposure to pollution increases their risk of an attack, which can be deadly.

The environment Bill is a once-in-a-generation opportunity to adopt the best standards to protect the public’s health by including legally binding targets for fine particulate matter in line with the limit recommended by the WHO. The current UK legal limit for PM2.5 is more than twice as high as that recommended by the WHO. Will the Government adopt the WHO’s limit into UK law, with a commitment to these standards to be met by 2030? This would guarantee a legislative framework based on the highest health standards and clear, legally binding targets to reduce pollution. Anything less than this would be a lost opportunity. We cannot wait until 2040 to implement this target. Many areas in the UK also experience illegal levels of nitrogen dioxide. Given that 37 out of 43 areas still have illegal levels of NO₂, it is critical to make changes so that we can comply with the legal limit as soon as possible. Will the Minister explain how this compliance will be enforced?

I hope that the Minister will agree that the rapid implementation of clean air zones across the UK’s most polluted areas needs to take place as soon as possible. They should restrict the use of the dirtiest vehicles, including private cars. As I am sure he knows, Defra’s own research shows that the best and quickest way to reduce polluting vehicles on our roads, and thus protect children from their harmful emissions, is the implementation of class D charging clean air zones right across the UK. This must be accompanied by the provision of clean public transport—not just private cars—and active travel, to reduce vehicle use. Will the Government provide more support for the implementation of such zones and more funding for clean public transport and active travel than they have done so far?

Finally, I turn to schools. With over 2,000 schools in areas with toxic air, as the noble Earl has already said, it is clear that a national comprehensive plan to protect children as they travel to and while they are at school is urgently needed. It should include comprehensive air quality audits of schools, nurseries and playgrounds in known pollution hotspots, to identify those affected by harmful levels of air pollution. It should also involve the absolute banning of new schools, nurseries and playgrounds in pollution hotspots. We need to introduce traffic exclusion zones around existing schools to help reduce and limit children’s exposure and to promote walking, cycling and public transport for journeys to and from school.

I hope the Minister will agree to the national rollout of tailored interventions around schools. Without changes of the kind that I have been describing—and to which the two speakers before me have also alluded—I am afraid to say that we will go on damaging our children’s lives and in some places, regrettably, killing them.
