Metro Vancouver enjoyed clean air and clear skies throughout 2019, with a total of zero days under an air quality advisory – a welcome change after two summers of unprecedented wildfire smoke. Monitoring data shows that levels of air contaminants generally fell in 2019, even as the region's population continued to grow.That's a key highlight from the 2020 edition of Caring for the Air, Metro Vancouver's annual state-of-the-air report. Now in its ninth edition, the report summarizes key air quality trends and describes Metro Vancouver's recent and upcoming actions to further improve air quality and address climate change in the region."Our region's clean air is something we all cherish," said Sav Dhaliwal, Chair of the Metro Vancouver Board of Directors. "The annual Caring for the Air report makes air quality science accessible and straightforward – it's a must-read for anyone interested in human health, environmental protection and climate change."The 2020 report covers topics like:Metro Vancouver's leadership on climate action and greenhouse gas (GHG) reductionThe effects of heavy truck traffic on air close to major roadsThe potential air quality impacts of ride-hailing servicesWhat the new wood smoke bylaw may mean for residentsWhy volatile organic compounds (VOC) emissions are important and how they are changingHow to improve resilience to heat waves, water shortages and wildfiresHow Metro Vancouver handles air quality and odour complaintsClimate change and air quality are strongly linked, since many major sources of greenhouse gases in the region are also major sources of health-harming air contaminants. Public and stakeholder consultation is currently ongoing on the Clean Air Plan, which will be the next iteration of Metro Vancouver's plan to manage air quality and greenhouse gases in the region."Efforts to improve air quality continue to pay off, and we must keep going boldly forward to address the challenges the region will face as climate change continues to affect our communities, infrastructure and ecosystems," said Adriane Carr, Chair of Metro Vancouver's Climate Action Committee. "Metro Vancouver is committed to accelerating actions to adapt to climate change and reduce GHG emissions, with the commitment of becoming a carbon-neutral region by 2050.""2020's Caring for the Air was prepared during the early phase of the COVID-19 pandemic response, and while there are indications of positive effects on air quality, it is too early to draw conclusions," added Chair Dhaliwal. "Next year's report will examine in detail how the public health response to COVID-19 affected air quality in Metro Vancouver and will contribute to discussions about resiliency and public health."Read the full 2020 Caring for the Air.
