I am glad the hon. Gentleman mentioned that, because the expectation is that the expansion of the ULEZ will reduce PM2.5 in outer London by 16%. He should know, but I am sure he does not, that studies at Harvard University and a Max Planck Institute found that covid deaths increased by between 8% and 12% when there was a marginal increase in air pollution from PM2.5—an increase much less significant than the fall that I mentioned. That is particularly relevant to poorer, more polluted areas and more diverse communities. We are talking here about life and death.
We know from studies done that there will be a massive reduction in PM2.5 and Nox as a result of the expansion. Indeed, there will be a major contribution towards mitigating climate change. The scheme already reduces carbon dioxide emissions by 12,300 tonnes; an expanded one will reduce it by 27,000 tonnes. We will be saving lives and saving the planet. The truth is that if we do not act, we will end up with 550,000 more people unnecessarily getting pollution-related diseases in the next 30 years, at an estimated cost of £10.4 billion. We should move forward on this. People who are neutral, such as the chief medical officer Chris Whitty, who has just released a report on air pollution, very much commend what Sadiq Khan is doing to save lives, as does the United Nations.
As a result of the ULEZ, there are 21,000 fewer vehicles in inner London and 67,000 fewer non-compliant ones—the latter figure is three times the former—so there are fewer vehicles overall. The scheme affects only 15% of vehicles—the most polluting—and £110 million has been set aside for scrappage schemes to enable conversion. The other thing to bear in mind is that the Government a year ago passed the Environment Act 2021. I wanted them to use COP26 to enforce World Health Organisation air quality standards, but instead, a year on, the Government are saying, “Why do we not try to get PM2.5 at 10 micrograms per cubic metre by 2040?”, as opposed to 2030, which was the previous deadline. The limit prescribed by the World Health Organisation is 5 micrograms, which Europe will achieve by 2030. We could achieve that here—this is a condition of doing so—with ultra low emission zones. Instead, the Conservative position is, “No, we will not bother with that. We will play politics with this, and continue to have 3,600 children every year in London going into hospital with asthma”, as my daughter did. That is unnecessary—and despicable, because it is avoidable.
