More than four in 10 children living in urban areas (43 per cent) are concerned about the levels of air pollution near their school, a survey has shown.

The YouGov poll, carried out for Sustrans – a walking and cycling charity – surveyed more than 1,000 children aged six to 15 about their attitudes towards air pollution and the actions they think should be taken to help clean up the air.

The findings also show that the number of children concerned about air pollution rose to 53 per cent in London and 57 per cent of the children surveyed said they were told about air pollution by their school.

Sustrans provides free information for schools, parents, pupils and councils interested in school travel initiatives.

Air pollution is one of the leading environmental public health crises in the UK today. Children are among the most vulnerable and figures show that more than 2,000 schools and nurseries are near to roads with damaging levels of motor emissions.
