Creating a ‘clean air generation’ of children and making sure new developments are clean by design

Public Health England publishes air pollution evidence review

Public Health England (PHE) has today published a 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.

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 local authorities can take 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 – for example designing wider streets or considering using hedges to screen against pollutants when planning new infrastructure
  • Discouraging highly polluting vehicles from entering populated areas – for example with low emission or clean air zones

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.


Public Health England was commissioned by the Department of Health and Social Care to review the evidence for effective air quality interventions and provide practical recommendations for actions to improve air quality.

PHE’s review built on Defra / DfT’s ‘UK plan to reduce roadside NO2’ published in 2017 and NICE’s guidance on outdoor air pollution which focussed on transport related interventions, to include other pollutants and reviews of interventions in industry, agriculture, transport and planning and behavioural change.

PHE’s review supported the development of Defra’s final Clean Air Strategy published in January 2019.
