New study suggests reported PAH emissions in oil sands region greatly underestimated

Green Car Congress

Results from a new modeling assessment of contamination in the Athabasca Oil Sands Region (AOSR) suggest that officially reported emissions of polycyclic aromatic hydrocarbons (PAHs) in that region have been greatly underestimated. Accounting for evaporative emissions (e.g., Average emissions densities from Shen et al.

Average carbon intensity of oil sands production has dropped ~36% in last 40 years; still 12-24% higher than conventional oil CI

Green Car Congress

The carbon intensity (CI) of Alberta oil sands production has significantly decreased over the last 40 years, according to a new study by a team from Stanford University published as an open access paper in the journal Environmental Research Letters. In situ production began in 1974, so no value is computable for 1970.
