This is the best summary I could come up with:

Rishi Sunak has “put decades of progress on clean air into reverse” and now risks “stunting the lungs” of London’s children by failing to support the expansion of the capital’s ultra-low emissions zone, Sadiq Khan has said.

Ahead of the clean air scheme’s rollout to all boroughs in the capital on Tuesday, the London mayor issued a stark warning to Sunak who he said risked going down in history as the prime minister who “had the chance to save lives but refused to take it”.

Khan, who has accused the government of weaponising air pollution and climate change to win votes, has urged ministers to provide financial support for his policy, and the accompanying scrappage scheme, as it does for some other cities in England.

Nearly 700,000 car drivers in Greater London face paying the £12.50-a-day Ulez charge from Tuesday when it is applied to all roads in the capital for the first time, according to figures obtained by the RAC, despite criticism that the move heaps financial pressure on struggling households.

After opposition to the Ulez expansion was credited by the Tories for their narrow byelection victory in Boris Johnson’s former west London seat of Uxbridge and South Ruislip last month, Sunak delayed and, in some cases, abandoned green policies that impose a direct cost on consumers.

The new London-wide zone also includes Heathrow airport for the first time, meaning drivers of older, more polluting cars making a one-off visit to the capital to fly or collect arriving passengers will also be hit by the scheme.
