Sometimes, it seems that all we get is bad news regarding the environment, but there is a lot of good work going on, such as cleaning up our air, water, and land. One area where we have made a lot of progress is cleaning up the air. Metro Vancouver is part of the Lower Fraser Valley airshed, and the Metro Vancouver Regional District completes a comprehensive inventory of air pollutants every five years.
They recently shared trends of air emissions from 2000 to 2020. The bottom line is that “today’s cleaner air saves the lives of approximately 580 Metro Vancouver residents each year, compared to air quality in 2001.”
The following tables show the reductions of certain emissions types.

Except for fine particulate matter emissions from wildfires, PM2.5 emissions are also declining.

Of course, more work needs to be done to reduce greenhouse gas emissions.
