A new report by Canada’s environmental agency finds extracting oil from the Alberta tar sands will more than offset emission reductions in other areas. According to the peer-reviewed report from Environment Canada, greenhouse gas emissions from oil sands are expected to triple to 92 million metric tons by 2020, up from 30 million metric tons in 2005. Canada’s current conservative government has abandoned more ambitious efforts to reduce greenhouse gas emissions, now aiming for a 17 percent decrease by 2020. According to the Environment Canada report, current measures will fall well short of the more modest target.
