My Lords, previously in Committee we have discussed the fact that polluted air is a growing national health emergency, and many noble Lords have talked about the terribly sad death of Ella Kissi-Debrah. The Bill provides an opportunity to improve people’s lives, which we must not miss. We support these amendments, which seek to do so.
On Amendment 150A, moved by the noble Baroness, Lady Sheehan, regarding the number of fine particulates released into the air from non-exhaust emissions and the role that speed reduction can play, noble Lords have spoken strongly in support of 20-mph speed limits and the wider benefits to society that those could bring. The noble Baroness talked particularly about the findings of the air quality expert group’s report. I also mention the Committee on the Medical Effects of Air Pollutants, which has made a statement on the evidence for health effects associated with exposure to non-exhaust particulate matter from road transport. These emissions currently comprise just under 10% of UK primary particulate emissions, but they are expected to become proportionately more important as vehicle exhaust PM emissions from road transport are expected to decrease over the coming years.
The committee said that as non-exhaust particles have a different composition—for example, higher metal concentrations—and a different size distribution from those emitted in vehicle exhausts, they may have different toxicological properties and health consequences. As this component of traffic emissions will become proportionately more important in future years, the recommendation from the committee is that new epidemiological and toxicological research should be undertaken to further understand the potential health risk of this aspect of vehicle pollution and to improve a basis for further policy. The noble Lord, Lord Lucas talked about the importance of carrying out research so that we have better understanding. Does the Minister’s department have any plans to undertake or commission such research? Are the Government considering speed reduction in areas of highest pollution?
I turn to Amendments 151A and 151B in the name of the noble Baroness, Lady Randerson. As we have heard, all local authorities have a duty to review and assess air quality within their district. The aim is to identify all areas where air quality is exceeding, or is likely to exceed, the air quality objectives. We agree with the noble Baroness that monitoring air quality standards at schools, hospitals and major roads is critical. In 2019, over 8,500 schools and almost 3,000 health centres were in areas with levels of PM2.5 above that recommended by the WHO, putting at risk the health of millions of children, patients and health workers.
The noble Baroness, Lady Randerson, mentioned the funding of local authorities, as did the noble Baroness, Lady Jones of Moulsecoomb. The burden of monitoring is on the shoulders of local government. If monitoring and compliance are likely to be increased, and given the chronic lack of funding for our local authorities, how do the Government intend to resource monitoring in order to ensure a sufficient degree of data integrity? My noble friend Lord Whitty spoke about the importance of this.
Amendments 153, 154 and 155, all in the name of the noble Baroness, Lady Jones of Moulsecoomb, consider the duties of the Secretary of State, local government mayors and the Committee on Climate Change, and how the monitoring of air quality and availability of related data to the public can be improved. She stressed the importance that this information must be accurately collected. But the need for improvements to the monitoring and assessment regimes should not be used as a reason to avoid setting the direction of travel now. As I have already said, we should use this Bill to start driving much-needed action, as soon as possible. The noble Baroness, Lady Walmsley, rightly reminded your Lordships’ House about the increased impact on deprived neighbourhoods if we do not take action.
I come to Amendments 156A to 156M in the names of the noble Lord, Lord Tope, and the noble Baroness, Lady Finlay of Llandaff. This series of proposed new clauses covers the control emissions from combustion plants. The noble Lord reminded your Lordships’ House that it is the anniversary of the Clean Air Act 1956. It would seem that the problem has not gone away; it has just changed. Combustion plants are a chief source of the power that lights and heats our homes. With a growing population of almost 70 million people, there are understandably tens of thousands of such facilities across the country. According to the latest figures collated by government, there are estimated to be between 30,000 and 35,000 medium combustion plants. As the noble Lord, Lord Tope, rightly says, we must have a focus on those emissions—but also local authorities will need the power to take appropriate action to tackle this area of poor air quality.
Finally, I pay credit to the noble Baroness, Lady Finlay of Llandaff, who has done so much work in this area. I believe that she made the critical points in the debate about the cost to our health and the number of avoidable deaths. The seriousness of this discussion cannot be underestimated, and I look forward to hearing from the Minister what further action the Government intend to take through this Bill to start to resolve these problems.
