Environment Bill

Baroness Walmsley Excerpts

Committee stage
Wednesday 23rd June 2021 Lords Chamber

We have an increasing problem of young people with asthma and an enormous bill for the NHS for acute and chronic respiratory disease. Can the Minister tell us what monitoring of air quality in schools and hospitals is currently being undertaken and what is planned, particularly where they are adjacent to major traffic routes?

[Baroness Walmsley (LD) [V]]

My Lords, I declare an interest as a sufferer from asthma. I add my congratulations and thanks to Rosamund Kissi-Debrah on her effective and courageous campaign for clean air. She, and anyone who knows anything about health promotion, knows that we should not rely on the Department of Health and Social Care alone to achieve it. It is the responsibility of the whole Government. Defra and the Department for Transport play particularly important roles.

Anyone who knows anything about ill health will also know that prevention is better and cheaper than cure. As my noble friend Lady Randerson pointed out, this group of amendments is about the prevention of ill health. My comments are from this standpoint. As my noble friend also pointed out, the beauty of the amendments in this group is that they bring together two vital issues for our country—the promotion of human health and the health of the planet. The prevention of global warming protects the future of our species. The practical measures needed to reduce PM2.5, which will prevent sickness, will also contribute to saving the planet.

As the noble Lord, Lord Young of Norwood Green, mentioned, these amendments also provide an opportunity for our innovators and industry to show what they can do to achieve the target by giving us a clean, green and more healthy recovery.

Amendment 20 requires an ambitious target, equivalent to that of the World Health Organization, for reducing air pollution, and it futureproofs the Bill. Amendment 49 puts pressure on the Secretary of State to do it quickly. We on these Benches support the spirit of Amendment 49, tabled by the noble Lord, Lord Whitty, Amendment 29, tabled by the noble Baroness, Lady Jones of Moulsecoomb, and Amendment 156, tabled by the noble Lord, Lord Kennedy, which summarises a lot of our objectives, as well as Amendments 20 and 49, to which I have put my name.

In this debate we have heard about the massive number of people whose health and development are seriously affected by polluted air, particularly by toxic microparticles of PM2.5 and smaller. We have heard that the Government currently meet their own average target of limiting this fine particulate matter to no more than 20 micrograms per cubic metre of air. However, this limit is too high and is an overall figure; local levels are much higher. We need much more granular measurement and enforcement. I welcome the Government’s commitment to adopting a new exposure reduction target, as this would drive further improvements in areas that already meet WHO guidelines, but this must go along with an ambitious target on ambient concentrations.

We have seen from Defra’s own technical analysis and from work by King’s College London that this is feasible and can be achieved, but it requires political leadership and funding. We have heard from the WHO and the noble Baroness, Lady Finlay of Llandaff, that no level of these microparticles is safe for human health, and that the legal limits in other countries are much lower than ours. We have also heard that the current limit recommended by the World Health Organization is 10 micrograms per cubic metre—half the UK limit—but that this is predicted to be reduced soon. Its guidelines also urge countries to reduce their own levels as quickly as possible. That is what we want our Government to do. The Government plan to set a new target by 2023. It must be an ambitious one. The Government should mandate themselves to keeping within that target and lay down a road map, with dates, as to how it will be done. Accepting these amendments would do that.

This Bill addresses many important issues but this one is by far the most far-reaching for our health, particularly that of our young children. Because these microparticles are so small, they can cross the placental blood barrier and enter a developing foetus, interfering with the development of the brain. If anything else did that, it would be banned by any right-thinking Government. This harm is hidden, so we do not know its human or economic cost. The dangers of rising levels of these particles have crept up on us, as the noble Lord, Lord Cameron of Dillington, said, but they can be stopped.

The Government like to claim that they are the “best in the world” at all sorts of things. Here is an opportunity to really achieve that position on damaging air pollution. If, by supporting this group of amendments, we can persuade the Government to take a more ambitious approach to reducing air pollution, we can save lives, save years of good health, save money for the NHS, stimulate the green economy and help save the planet. As they say, “What’s not to like?”

[Lord Goldsmith of Richmond Park (Con)]

I thank noble Lords for their contributions on this important subject. I start by saying, as a number of noble Lords have, that the death of Ella Adoo-Kissi-Debrah was an absolute tragedy. I pay tribute to her family and friends, particularly her mother, who have all campaigned so tirelessly on this issue and continue to do so.

Turning to Amendment 20, tabled by the noble Baroness, Lady Jones of Whitchurch, the Government recognise the importance of reducing concentrations of PM2.5 and the impact this has on our health. That is why we have included in the Bill the requirement to set a target specifically on PM2.5 concentrations. The Government are following an evidence-based process to inform this and the long-term air quality target. I reassure my noble friend Lord Randall, the noble Lord, Lord Wigley, and the noble Baroness, Lady Walmsley, that it will be ambitious. However, at this stage the full mix of policies and measures required to meet the current WHO guideline level of 10 micrograms per cubic metre is not yet fully understood, and nor is the impact these measures would have on people’s lives. The noble Baroness, Lady Hayman, mentioned the mayor’s study. I am pleased to say that the workings of that study were published last week. Officials are going through them and taking them into account. The letter on this issue recently sent to the Prime Minister by the UK Health Alliance on Climate Change, the BMA and a collaboration of medical colleges will also be taken into account.

Until the Government complete the work and consult the public about the type of restrictions that would need to be placed upon us, particularly in large cities, it would not be appropriate for us to write this limit into law. The target is not being ruled out but, as I said at Second Reading, there is work to do. For example, meeting 10 micrograms in London and other cities is likely to require policies such as a total ban of solid fuel burning in cities and reducing traffic kilometres across our cities by as much as 50%. It is not right for us to set a target at the stroke of a pen that would impact millions of people and thousands of businesses without first being clear with people and understanding what would be needed. The Government have committed to setting out detailed evidence, including for public consultation, early next year, ahead of setting this target in secondary legislation, which will come before this House for a debate and a vote.

Turning to Amendment 29, tabled by the noble Baroness, Lady Jones of Moulsecoomb, Amendment 49, tabled by the noble Baroness, Lady Jones of Whitchurch, and Amendment 156, tabled by the noble Lord, Lord Kennedy of Southwark, the Government are working with a broad range of experts to ensure that air quality targets are based on the best available science, including the Committee on the Medical Effects of Air Pollutants, the UK’s air quality expert group, and a wide range of sector experts. We will ensure that our process is informed by the latest health evidence, including World Health Organization air quality guidelines. Given the breadth of potential targets that could be set under this framework, the WHO guidelines might not be relevant to all targets. Therefore, it would be inappropriate to require the Government to take account of the guidelines when setting or amending all targets. Nor would it be appropriate to require the Government to prepare explanatory statements pertaining to the guidelines for all targets, or to require all targets to be reviewed when the new WHO guidelines are issued.

However, we have baked a review mechanism into the target monitoring and review process. At least every five years, the Government must consider whether further policies are needed to achieve the interim and long-term targets they have set under the Bill. This will mean considering new evidence, including in the context of air quality target updates to World Health Organization guidelines.

Turning to Amendment 156, in the name of the noble Lord, Lord Kennedy, the Government already make air pollution information available through a range of channels, but we are committed to improving the quality of that information first, to ensure that we have clear messaging and strong platforms to host this information. We will be doing this through comprehensive reviews of UK AIR, and the daily air quality index, and dedicating a significant part of the £8 million air quality grant to improving public awareness in local communities of the risks of pollution. This will also help health professionals in advising patients when poor air quality is forecast. We are also looking at working with relevant health charities on longer-term campaigns aimed specifically at vulnerable groups.

Moving to Amendment 21, tabled by the noble Lord, Lord Whitty, I reassure noble Lords that the Government recognise that in setting new air quality targets, it is important to have in place suitable means to monitor progress and to demonstrate whether the targets have been met. To answer noble Lords, particularly the noble Lord, Lord Whitty, there is an established network of air quality monitoring in the UK, and work is ongoing to understand what additional monitoring would be required to underpin the new air quality targets. As stated in our clean air strategy, we are committed to ensuring continued investment to update and improve this infrastructure, in order to ensure that appropriate assessment is possible and that progress can be tracked. The noble Baroness, Lady Finlay, also made that point.
