Measures including no-idling zones outside schools have been recommended by Public Health England in its review of evidence on how to improve air quality in the United Kingdom.
The review informs local and national government on actions to improve outdoor air quality and health.
The review of air quality policies said local authorities should work with parents and children to stop drivers leaving their engines running outside the school gates. It’s hoped that such a measure would help to reduce the amount of harmful particulate matter children are exposed to in town centres.
Air pollution is the biggest environmental threat to health in the UK, with between 28,000 and 36,000 deaths a year attributed to long-term exposure. There is strong evidence that air pollution causes the development of coronary heart disease, stroke, respiratory disease and lung cancer, and exacerbates asthma.
Professor Paul Cosford, Director of Health Protection and Medical Director at PHE, said: “Now is our opportunity to create a clean air generation of children, by implementing interventions in a coordinated way. By making new developments clean by design we can create a better environment for everyone, especially our children.”
Key interventions suggested to local authorities also include:
Promoting a step change in the uptake of low emission vehicles – by setting more ambitious targets for electric car charging points, as well as encouraging low emission fuels and electric cars
Boosting investment in clean public transport, as well as foot and cycle paths to improve health
Redesigning cities so people aren’t so close to highly polluting roads
Discouraging highly polluting vehicles from entering populated areas - for example, with low emission or clean air zones
This work could involve designing wider streets, or considering using hedges to screen against pollutants when planning new infrastructure.
Professor Cosford said: “We recommend that at a local level, any new policy or programme of work which affects air pollution should aim to deliver an overall benefit to the public’s health.
“So transport and urban planners will need to work together, with others involved in air pollution to ensure that new initiatives have a positive impact.
“Decision makers should carefully design policies, to make sure that the poorest in society are protected against the financial implications of new schemes.
“National government policy can support local actions by creating the right incentives. These include policies which promote vehicles with low exhaust emissions or allow controls on industrial emissions in populated areas to take account of health impacts.”
