Oil sands GHG lifecycle study using operating data finds lower emitting oil sands cases outperform higher emitting conventional crude cases; a call for more sophisticated tools and reporting

Green Car Congress

Well-to-wheel (WTW) greenhouse gas emissions for in situ SAGD and surface mining pathways generated employing GHOST/TIAX/ GHGenius combination and comparison with SAGD, mining and conventional crude oil literature pathways (all results are on a HHV basis). 74% of WTW emissions in our oil sands pathways.

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

Green Car Congress

Full-fuel-cycle GHG emissions estimates for reformulated gasoline pathways by LCA study. He found that the variation in oil sands GHG estimates is due to a variety of causes. These include oil sands, enhanced oil recovery, coal-to-liquids and gas-to-liquids synthetic fuels, and oil shale.

Study finds plausibly high volumes of Canadian oil sands crudes in US refineries in 2025 would lead to modest increases in refinery CO2 emissions

Green Car Congress

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.

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.

ExxonMobil Outlook: 35% growth in energy demand by 2040; hybrids to account for ~50% of new vehicle sales

Green Car Congress

ExxonMobil projects that meeting future energy demand will be supported by more efficient energy-saving practices and technologies; increased use of less-carbon-intensive fuels such as natural gas, nuclear and renewables; as well as the continued development of technology advances to develop new energy sources.

Argonne study finds shale gas GHG lifecycle emissions 6% lower than natural gas, 23% lower than gasoline and 33% lower than coal; upstream methane leakage a key contributor

Green Car Congress

Gasoline section shows results for fuel derived from both conventional oil and oil sands. However, the range in values for shale and conventional gas overlap, so there is a statistical uncertainty whether shale gas emissions are actually lower than those of conventional natural gas.

Study concludes transport regulations should focus on energy-intensity-based fuel standards along with regulation of upstream carbon-intensity; decomposing transport GHG emissions into 3 factors

Green Car Congress

Decomposition of greenhouse gas emission in transportation (A), relevant actors (B), and corresponding policy instruments (C). volume and GHG-based fuel standards) to achieve reductions in greenhouse gas emissions from on-road transportation need to evolve towards energy-intensity-based fuel standards (e.g.,
