The Georgia Basin-Puget Sound International Airshed Strategy is a multi-agency, international co-operative effort to address shared air quality management concerns. These include impacts to human and environmental health specific to this region. This strategy also aims to prevent future deterioration of air quality, and is particularly important due to the recent significant regional population growth, which is expected to continue for at least the next two decades. Government agencies in Canada & US with a responsibility for air quality are interested in ensuring that the region’s air quality is protected for present and future generations. It is for this reason that various governments, along with First Nations/Tribal agencies and non-governmental organizations, are working to develop the Georgia Basin-Puget Sound International Airshed Strategy.
