For the Association québécoise de lutte contre la pollution atmosphérique, by reducing greenhouse gas emissions, we're clearly reducing the polluting emissions that cause smog.
Most smog-causing pollutants are produced through the combustion of fossil fuels. If we address fossil fuels, we thereby address the main contaminants that form smog. It's important to target greenhouse gas emissions on a priority basis because we achieve a range of gains for both health and environmental quality.
