Changes to the Non-Road Diesel Engine Emission Regulation Bylaw 1161

Metro Vancouver introduced Metro Vancouver Regional District Non-Road Diesel Engine Emission Regulation Bylaw No. 1161 in 2012 to manage older, higher polluting non-road diesel engines as one of the prioritized initiatives in an overall program to improve air quality in the region.

Fine particles produced by the combustion of diesel are the primary air quality threat to human health in Metro Vancouver, and they also contribute to climate change and reduced visibility. Fine particles from diesel combustion have been associated with both short and long-term health effects, from aggravated asthma to heart and respiratory diseases.
