This report is an update to the 2007 Inventory of Air Quality Bylaws in British Columbia. It is intended to serve as a resource for local governments to create or further develop legislation to improve local air quality. This report focuses on vehicle idling, open burning, and wood burning appliance bylaws, which have been identified as particular areas of concern due to their impacts on local air quality and public health. All municipalities and regional districts in BC were contacted to gather information on the air quality bylaws they have created or updated since 2007. Additional information was collected on the enforcement, compliance and education activities pertaining to these bylaws. Results indicate an increasing number of air quality bylaws in BC, but also illuminate issues of inconsistency across the province, as well as difficulties with enforcement.
