CLEAN Air Day is always particularly poignant at Gorse Hall Primary, Stalybridge, given its location.
This year pupils made kite promises to help change lifestyles to mitigate air pollution.
Each child made a thumb print pledge to walk or cycle to school, car share or use public transport.
Teacher Kathleen Hughes explained: “Air pollution, an invisible killer, is something we take seriously as we are on a main road.
“It affects 15 per-cent of our children and staff who are asthma sufferers and we are therefore more focused on it.
“Many of our children walked to school or part of the way if they lived a distance away.”
Gorse Hall has an air pollution monitor outside school and also recently helped launch a new initiative to persuade motorists to switch off their engines when parked outside school to improve air quality.
