MONTREAL — Canada should focus more on global impact than on local reduction efforts in its attempts to rein in greenhouse gas emissions, according to a new study. “Relocating a polluting factory from Quebec to the other side of the world might make our local emissions look great, but it’s doing zilch for the climate,” said Krystle Wittevrongel. …The publication highlights the risks of carbon leakage, whereby high-emission activities are simply exported outside the country, a problem that stems from focusing strictly on local emissions reduction. Indeed, if the new location has less stringent environmental standards than Canada, such carbon leakage may well increase global emissions. The study’s author also points to the very small share of worldwide greenhouse gas emissions that come from Quebec, and even from Canada as a whole, as opposed to the large and rapidly increasing shares of fast-developing nations such as India and China.
