An analysis of the US refining sector, based on linear programming (LP) modeling, finds that refining plausibly high volumes of Canadian oil sands crudes in US refineries in 2025 would lead to a modest increase in refinery CO 2 emissions (ranging between 5.4% to 9.3%) from a 2010 baseline, depending upon the supply scenario.

Comparison of the percent differential for WTW (well-to-wheel) GHGs from gasoline produced from WCSB oil sands using different production processes relative to gasoline produced from reference crudes. The proposed Project is not likely to impact the amount of crude oil produced from the oil sands.

Average values for WTW GHG emissions for oil sands and other crudes, tight boundary. When the oil sands products refined in the United States are considered—a mixture of oil sands and lower-carbon blending components—the GHG emissions are, on average, 9% higher than the average crude processed in the US.
