About C40 Clean Air Cities Declaration:

Through this Declaration, mayors commit to using their power and influence to reduce air pollution and work towards meeting the World Health Organization’s Air Quality Guidelines.

This means cities will continually reduce their local emissions, and advocate for reductions in regional emissions, resulting in continuous declines in air pollution levels that move towards the WHO guidelines.

 

Signatories of the declaration pledge to:

  1. Set ambitious pollution reduction targets within two years that meet or exceed national commitments, putting them on a path towards meeting World Health Organization guidelines;
  2. Implement substantive clean air policies by 2025 that address the unique causes of pollution in their cities; and
  3. Publicly report progress on achieving these goals.

 

Expected outcomes:

  1. If the 35 signatories reduce annual average PM2.5 levels to WHO guidelines (10 ug/m3) it could avoid 40,000 deaths each year. 
  2. C40 research shows that if all C40 cities cleaned their transport, buildings and industry this would reduce GHG emissions by 87%, PM2.5 by nearly 50% and would avoid over 220,000 premature deaths per year.
