David Suzuki is misrepresenting Canada’s environmental record again.

In a recent opinion piece, the longtime broadcaster, scientist and environmental activist tells Canadians that their nation is a world laggard in environmental protection.

“Canada ranks 25th among rich countries on children’s well-being, in part because of our failure to improve air quality,” Suzuki claimed.

This is simply false. Any empirical evaluation shows that Canada’s air quality has substantially improved over the past few decades.

Canada’s air quality conforms to the strictest standards in the world. A recent Fraser Institute study used a massive archive of data from Environment Canada to examine the evolution of air quality from the 1970s onward, spotlighting emissions and ambient concentrations (the amount of pollutants in the air) of five major air pollutants: ground-level ozone, fine particulate matter, sulphur dioxide, nitrogen dioxide and carbon monoxide. The results show Canada’s air pollution has substantially declined and complies with the world’s strictest air quality standards.

Ambient levels of ground-level ozone, an air pollutant caused by emissions, decreased 27 percent from 1979 to 2015. In the late 1970s, more than 70 percent of air-quality monitoring stations across Canada reported ozone concentrations above the air-quality standard, but by 2015 this number had fallen to 16 percent. And from 2000 to 2015, fine particulate matter (smoke, aerosols, etc.) concentrations consistently remained below the most stringent air-quality standard.

It’s the same story for Canada’s ambient levels of sulphur dioxide, a pollutant largely associated with the combustion of oil and coal. That plummeted by 92 percent from 1974 to 2015.

And in the last four decades, Canada experienced substantial reductions in nitrogen dioxide and carbon monoxide – two pollutants largely associated with automobiles. National levels decreased by 74 percent and 90 percent respectively from 1974 to 2015. Again, in the mid-1970s, 54 percent of monitoring stations across Canada reported readings out of compliance with the annual air-quality standard for nitrogen dioxide but by 2015, that percentage was zero.

Other studies show similar results. For example, a recent study by Yale University compared Canada with other countries on several environmental indicators, including air quality. The study included four indicators measuring average exposure, health risks to key air pollutants and the percentage of the population burning solid fuel indoors. Canada ranked 36th among 180 countries and sixth out of 16 high-income countries.

Environmental activists such as Suzuki falsely accuse Canada of having poor air quality and reflexively call for stronger air-quality standards, yet they never discuss the data.

Canada has dramatically reduced air pollution since the 1970s and complies with the tightest air quality standards anywhere. Imposing tighter regulations and tougher emission policies will come with high economic costs, without generating significant environmental benefits.

Canadians have nothing to hang their heads about when it comes to environmental protection and air quality. In fact, Canada’s environmental record is an achievement we should be proud of and celebrate.
