Canada’s a global leader on clean air – by Lorrie Goldstein (Toronto Sun – April 20, 2017)

The question now is whether carbon pricing to reduce greenhouse gases is
worth the added cost to Canadians in terms of the higher taxes and prices
they will have to pay for almost all goods and services, considering that
Canada produces only 1.6% of global greenhouse gas emissions.

A Fraser Institute study released Thursday comes as a welcome breath of fresh air to Canadians tired of being harangued by politicians and so-called “green” activists as environmental laggards. The study shows a dramatic improvement in Canadian air quality since 1970, despite economic growth, an increasing population and greater energy consumption, making Canada a world leader in reducing air pollution.

It won’t change the debate over man-made climate change because the Fraser Institute is talking about traditional sources of air pollution, rather than industrial greenhouse gases – primarily carbon dioxide – linked to global warming.

But the study by University of Guelph economics professor Ross McKitrick and economist Elmira Aliakbari entitled, “Canada’s Air Quality since 1970: An Environmental Success Story” lives up to its name.

As McKitrick rightly notes: “Canadians should be proud of their environmental record, as air pollution that accompanied more than 100 years of industrialization has been reduced to extremely low levels and Canada has now achieved some of the strictest air quality targets in the world.”

The study found that from 1975 to 2015, concentrations of sulfur dioxide in the air fell 92.3%, nitrogen dioxide 74.4% and carbon monoxide 90.4%.
