Mr Bailey has warned taxing motorists “isn’t the way to solve air pollution” in the capital and has promised to reduce emissions without increasing taxes. Mayor Sadiq Khan is set to launch a new ULEZ expansion to Outer London boroughs coming into force from October.
The new ULEZ charge will continue to operate 24 hours a day, 7 days a week including weekends which will affect millions of residents.
Transport for London has predicted four out of five cars already meet the tough ULEZ restrictions and will not face any charges,
Instead, the focus is on targeting owners of older polluting cars, motorcycles, lighter vans and minibuses.
However, Mr Bailey has warned his choices would keep the cost of living down for those living in London.
The scheme has also seen the number of vehicles meeting emission standard resid from 39 percent in February 2017 to more than 80 percent today.
A statement warned pollution levels were returning to “pre-pandemic levels” as they warned action needed to be taken.
They said: “Despite recent improvements in air quality, toxic air pollution in London remains the biggest environmental risk to the health of all Londoners.
“It harms our lungs worsens, chronic illnesses such as asthma, lung and heart disease, and puts the health of our children at risk.
“Air pollution is not just a central London problem, with many areas across the city still exceeding the legal limits for pollution.
“Pollution levels are now returning to pre-pandemic levels across the capital.”
