And Syncrude’s Mildred Lake mine was emitting two-and-a-quarter times more of the climate-change-causing gas than it told Ottawa’s pollutant registry.“We find a pretty significant difference,” said Liggio, whose paper is published in Nature Communications.WATCH: Canadians wants climate change action, but not at any cost, poll says
