Canadian Oil Sands: Life-Cycle Assessments of Greenhouse Gas Emissions
This paper investigates the impacts of the increased petroleum production from Canadian oil sands, highlighting the main concerns over the potential environmental impacts. The studies identify two main reasons for the increase: (1) oil sands are heavier and more viscous than lighter crude oil types on average, and thus require more energy- and resource intensive activities to extract; and (2) oil sands are compositionally deficient in hydrogen, and have a higher carbon, sulfur, and heavy metal content than lighter crude oil types on average, and thus require more processing to yield consumable fuels.
