The Globe and Mail reports in its Saturday, May, 13, edition that the Competition Bureau said on Thursday it was investigating whether Pathways Alliance, a group of oil sands producers collaborating on ways to cut greenhouse-gas emissions, misled the public in its advertising campaign. A Reuters dispatch to The Globe reports that three environmental groups complained to the bureau in March about Pathways' "Let's clear the air" campaign that promoted the producers' plan to achieve net-zero emissions by 2050. The bureau reviewed the complaint to determine if it meets technical requirements of Canada's Competition Act prior to launching a formal investigation that is then required by law to determine the facts, a Competition Bureau spokesman said. The bureau, an independent agency of the federal government, has authority to order financial penalties. The environmentalists said Pathways' net-zero claim was misleading because 80 per cent of the emissions associated with oil and gas are related to combustion, not the initial extraction on which Pathways is focused. Greenpeace Canada's Nola Poirier says, "We think the public deserves to be told the truth about the environmental harm caused by fossil-fuel production."
