Argument: Oilsands account for less than 1 percent of global emissions
In an op-ed in the Argus Leader, John Duff Erickson, professor emeritus at the South Dakota School of Mines and Technology, wrote: "It would be folly to halt oil sands production and the construction of pipelines that would carry Canadian oil to U.S. markets. Oil sands development accounts for less than 1 percent of global greenhouse-gas emissions."
Tom Huffaker. "The case for optimism: Some perspective on oil sands." San Francisco Chronicle. October 09, 2009: "oil sands account for five per cent of Canada's emissions, Canada accounts for two per cent of global emissions, therefore oil sands represent one tenth of one percent of global emissions."
