Leading doctors and scientists have warned politicians against watering down plans to expand city-wide schemes aimed at reducing traffic pollution levels linked to thousands of deaths each year.
They urged politicians not to lose their nerve over plans to improve poor air quality, such as the expansion of the ultra low emission zone (Ulez) in London, which they said were central to tackling “unacceptably high” levels of illness and child deaths, and called for more ambitious policies to reduce toxic air.
