In the longer-term, replacing normal vehicle volumes with EVs would have the same life-saving effect If you’re spending all your time isolating indoors, you might not have noticed, but Canada’s cities are currently experiencing a dramatic decrease in pollution and fossil fuel emissions. The big difference maker: fewer cars and trucks on the roads. The air-clearing impact of reduced emissions — not just carbon dioxide (CO2), which warms the planet, but nitrogen dioxide (NO2), a major factor in smog and other harmful particulate air pollution — is revealed in the following maps from satellite data analytics provider Descartes Labs. “Air pollution produces approximately 14,000 early deaths each year in Canada” – Robin Edger, Executive Director and CEO of the Canadian Association of Physicians for the Environment The images compare the average levels of atmospheric NO2, a pollutant created from burning fossil fuels such as gasoline, in the areas surrounding Toronto, Vancouver, Edmonton and Calgary in recent […]
