What is an Airshed? 

Watch this animated video to learn more about Airsheds in Alberta and what we do.




Alberta’s Airsheds 

WCAS is one of 10 Airsheds in the Province of Alberta.

As Alberta’s inaugural Airshed organization, WCAS is responsible for:

Monitoring air quality in the region

  • West Central Airshed Society (WCAS) monitors data from 12 continuous air quality monitoring stations located throughout the Airshed region. 


Providing credible, science-based data and educational outreach to all stakeholders

  • WCAS identifies and quantifies air quality concerns, recommends and implements management solutions for the region
  • We coordinate and integrate airshed monitoring and management activities within the region with provincial policies and guidelines as developed by provincial air quality stakeholders in their respective areas of authority
  • We promote understanding between WCAS, governments, stakeholders, the public, and other organizations about environmental impacts of activities inside and outside the airshed in regard to air quality


Working collaboratively to better air quality in West Central Alberta

  • WCAS provides a forum for discussion and co-ordination of matters related to the management of air monitoring
  • We design monitoring programs to identify and quantify air quality concerns.  The Board develops and implements options to address concerns 


Globally, air pollution is responsible for an estimated 6.5 million deaths annually, or one in nine premature deaths every year.

This makes it the world’s largest environmental health risk, and among the largest global health risks according to the World Health Organization.

At WCAS, we join the call-to-action outlined by United Nations Sustainable Development Goals  knowing that reducing air pollution and improving air quality will help ensure a better future for us all. Click on the brochure for more information.
