Clean Air Day, the UK’s largest air pollution campaign led by Global Action Plan, brings together communities, businesses, schools and the health sector and engages with thousands of people at hundreds of events to improve public understanding of air pollution, build awareness of how air pollution affects our health and explain the easy actions we can all do to tackle air pollution, helping to protect the environment and our health.
