Understanding the variability of GHG life cycle studies of oil sands production

Green Car Congress

In a paper published in the ACS journal Environmental Science & Technology , Stanford University assistant professor Adam Brandt reviews a number of recent life cycle assessment (LCA) studies calculating greenhouse gas (GHG) emissions from oil sands extraction, upgrading, and refining pathways—the results of which vary considerably.

Two Lifecycle Studies Find Greater Range in GHG Emissions from both Conventional and Oil Sands Derived Crude Than Previously Shown; Oils Sands Emissions Comparable to Conventional Oil Production in Some Cases

Green Car Congress

Two new lifecycle studies have found that direct greenhouse emissions from producing, transporting and refining oil-sands derived crude, while greater on average than those from conventional crudes, can also overlap the conventional crude range, depending upon a number of factors.
