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.

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.

Researchers Suggest That Although CCS and Other Technologies Could Reduce Oil Sands GHG Emissions to Near Zero, That Strategy May Not Make Sense

Green Car Congress

Examples of emerging oil sands related technologies and trade-offs. The paper is an examination of how various choices about the scale of the life cycle analysis applied to oil sands (i.e., The source material is neither oil nor tar but bitumen, but is most generally described as an example of ultraheavy oil.”.

State Department issues Draft Supplemental Environmental Impact Statement on Keystone XL Pipeline: climate change impacts

Green Car Congress

The US Department of State (DOS) has released its Draft Supplemental Environmental Impact Statement (SEIS) in response to TransCanada’s May 2012 application for the Keystone XL pipeline that would run from Canada’s oils sands in Alberta to Nebraska. The pipeline would primarily transport crude oil from the WCSB and Bakken regions.

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. Click to enlarge.
