What can cities do?

On 5 June 2019, World Environment Day will be on the theme of “air pollution”— a call to action to combat one of the greatest environmental challenges of our time. Hosted by China, World Environment Day invites us all to consider how we can make changes in our daily lives to reduce air pollution, which in turn can reduce greenhouse gas emissions and benefit people’s health too. China has demonstrated tremendous leadership in tackling air pollution domestically and its commitment to improving air quality can serve as an inspiration to countries around the world.

Our Campaign 

Together we can #BeatAirPollution and cities around the world are invited to take part. Explore this site to learn about the different types of air pollution and why they matter to you using infographics, quizzes, and stories from around the world.

Discover what cities can do

Consider using World Environment Day to make commitments on improving air quality by curbing transport and energy emissions and creating more green spaces. Here are some ideas: 

  • Offer free transport in urban areas to encourage drivers to leave their cars at home.
  • Do a tree-planting day on 5 June.
  • Pledge to phase out diesel buses and trucks, as cities such as Madrid, Paris, Athens, and Mexico City have done.
  • Look at landfill gas recovery as an energy option that harnesses land ll emissions rather than allowing them to enter the atmosphere or our lungs.
  • Register your event here.
