Levels of deadly pollutants have dropped, with significant improvements in capital’s most deprived areas
People in London have been breathing significantly cleaner air since the expansion of the ultra low emission zone (Ulez), a study has found.
Levels of deadly pollutants that are linked to a wide range of health problems – from cancer to impaired lung development, heart attacks to premature births – have dropped, with some of the biggest improvements coming in the capital’s most deprived areas.
Sadiq Khan had faced severe opposition to the 2023 expansion of Ulez to outer London boroughs. But on Friday as the report was published, the mayor of London said the scheme had driven down pollution, taken old polluting cars off the roads and brought cleaner air to millions more people.
