I am just going to answer this question.

Yes, the WHO has already lowered what it thinks is the safe limit, which I think demonstrates how complicated the issue is. It would be wrong to set a number on the face of the Bill without being absolutely certain that it was the right one—as my hon. Friend understands. I have spent a great deal of time on this issue with academics and scientists, and I am happy to share with others if that is helpful. We must make sure we get this right before we set the target. To be clear, to achieve even the 10 micrograms per metre squared in our cities would require significant change in all our lives. It would likely introduce policies aimed at restricting traffic kilometres by as much as 50% or more, a total ban on solid fuel burning including wood, and significant changes to farming practices to reduce ammonia, which reacts in the air to form particulate matter.

I thank the hon. Gentleman for that intervention and for all his work in this area. In the spirit of being friendly, I have a smile on my face, but I would say that we are not moving slowly. He did not even reference the clean air strategy, which the WHO commended as being a world-leading piece of legislation. That is already bringing in measures across the country. There is also the £3.6 billion in the nitrogen oxide programme. The new air quality Minister—the Under-Secretary of State for Environment, Food and Rural Affairs, my hon. Friend the Member for Bury St Edmunds (Jo Churchill)—who is sitting here, has a very big health interest. We are taking this extremely seriously. We need to look at the wider context and the Bill will then set the two targets—not just the average target, but the population exposure target, which is really important.

Given that the World Health Organisation had a target of 10 micrograms per cubic metre, which we are asking for in this amendment, and it is now 5 micrograms, does that not show that the only direction is down? Ten micrograms is a minimum standard that we surely need to achieve both to save tens of thousands of lives and to tell the world, through COP26—8.7 million people are dying every year of air pollution—that global Britain means showcasing the fact that we are willing to provide legally binding targets to deliver on public health, care costs, productivity and a cleaner, greener, better world.

I thank the hon. Gentleman for that intervention. We have met many, many times and we share a common interest in this issue. We are not arguing about its importance—[Interruption.] He is encouraging me—I thank him, but I do not need any encouragement actually; we realise how serious this is. The point is that we will be setting the target and we will be showing the world. We will announce that target next October, but we will consult on it before that. It would be wrong to set, for example, a specific number, if, indeed, we found that that number should be lower. I will leave it there.

We have to have a public consultation on this issue and we will do so early next year. Members of the public will want to understand not only the health impacts, but what impacts the measures that will be taken will have on their life. But we will not be sitting around. The consultation will allow us to bring forward the final target in October, and we cannot miss that target.

I would suggest a meeting with the new air quality Minister—actually, I meet Sir Stephen Holgate regularly, as he is one of our advisers. We are increasing monitoring across the country for exactly the purposes that the hon. Gentleman mentions: the better the data, the more we know what action we can take.

The targets that we are working on are being carefully approached with experts such as Sir Stephen Holgate, as well as others from Imperial College London and the UK Centre for Ecology & Hydrology. We have two expert panels: the air quality expert group, chaired by Professor Alastair Lewis, and the committee on the medical effects of air pollutants, chaired by Anna Hansell of the University of Leicester. That will ensure that we get the targets right and that they are informed by the latest atmospheric science and health evidence. We will, of course, share those findings with the World Health Organisation.

Will the Minister give way?

I am going to plough on for a bit, because I think I have been pretty generous so far. The two targets that we will set—a concentration target and a population exposure reduction target—will work together to both reduce PM2.5 in areas with the highest levels and drive the continuous improvement that we need. A focus on reducing population exposure, not just a concentration-based target, recognises that there is no safe level of PM2.5, and a scientific approach is absolutely the right way to go. We recognise that this will not be easy and that we need to engage with society to bring it along with us.
