Alberta emits more greenhouse gases than any other province in Canada and could single-handedly prevent the country from complying with the Kyoto treaty on climate change, according to a study released yesterday by the Pembina Institute, an environmental think tank. The study predicts that Alberta’s emissions of greenhouse gases will rise about 65 percent from 1990 levels if plans go forward to build more coal-fired plants and extract big amounts of oil from tar sands. Under Kyoto, Canada has agreed to reduce its emissions by 6 percent below 1990 levels by 2012. The study said provinces in Canada in general have failed to do much to curb global warming, and it attributed the problem to “a lack of political will, not a lack of policy options.”
