Air Pollution in Canada

Canadians Believe that air pollution is their biggest environmental health issue. Climate change is a growing concern. There are many links between these two issues. For example, when fossil fuels like oil, natural gas, coal and gasoline are processed and burned to heat our homes and buildings, power our factories, generate our electricity, and fuel our vehicles, they generate emissions that contribute to both air pollution and climate change. Reducing the use of non-renewable sources of energy can lessen air pollution and greenhouse gas emissions.

Air pollution from pulp mills, an important industry in many parts of Canada, is not well studied. Mills should be, but usually are not, monitored for a range of air emissions, such as particulate matter, carbon dioxide, sulfur dioxide, hydrogen sulfide, volatile organic compounds, chlorine, chloroform, and chlorine dioxide. Incomplete data from British Colombia's Environment Ministry indicates that in 1997, mills in this Canadian province emitted 17,000 tons of particulates and 2.7 million tons of carbon dioxide, plus other unreported emissions. Air discharges from pulp mills contain hormone-disrupting and carcinogenic chemicals, such as chlorinated phenols, polycyclic aromatic hydrocarbons (PAHs), and VOCs. British Colombia's coastal pulp mills are the largest provincial source of airborne dioxins and furans, which are among the most toxic substances known.

Despite having met emission reduction targets, Canada has made only limited progress thus far in meeting ambient air quality objectives. This has reflected three continuing trends:

A proposed new environmental protection act, slated for passage in 1997, is in part designed to address these problems, particularly through a greater emphasis on pollution prevention rather than control and new provisions controlling motor vehicle emissions and regulating fuels. A more general issue on the Canadian environmental agenda that is especially important for air quality improvement, is harmonization, or improving the coordination of policies across levels of government.
