Why it's important

  • Air quality affects everyone's health. Hertfordshire has some of the worst air pollution outside of London.
  • Children's health can be especially affected. High pollution is linked to respiratory conditions such as asthma.
  • New research shows that air pollution from motor exhaust fumes may increase the risk of dementia.

The difference you can make

  • Turn your car engine off when you're not driving and stop pollutants entering the air. Be especially careful near schools.
  • Leave your car at home and share your journey, so there are less vehicles on the road.
  • Walk or cycle if possible and travel sustainably.

Show your support

  • Talk about this issue with your family, friends and colleagues, and share this information with them.
  • See the Clean Air Day website for more information or to make a pledge.
