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 releases final environmental impact statement on Keystone XL Pipeline Project; analysis of GHG emissions

Green Car Congress

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.

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.,

Stanford, UC Santa Cruz study explores ramifications of demand-driven peak to conventional oil

Green Car Congress

In contrast to arguments that peak conventional oil production is imminent due to physical resource scarcity, a team from Stanford University and UC Santa Cruz has examined the alternative possibility of reduced oil use due to improved efficiency and oil substitution. 2010, to above 140 $/bbl in constant 2010 dollars).

Refiners and Truckers Associations Challenge California LCFS in Federal Court

Green Car Congress

The California LCFS calls for at least a 10% reduction from 2006 levels in the carbon intensity (measured in gCO 2 e/MJ) of California’s transportation fuels by 2020.

Group of Scientists and Economists Urge Inclusion of Indirect Land Use Change Effects for Biofuels and All Transportation Fuels in California LCFS

Green Car Congress

More than 170 scientists and economists have sent a letter to California Air Resources Board (ARB) Chairman Mary Nichols urging the board to account for greenhouse gas emissions from indirect land use change for biofuels and all other transportation fuels under the state’s proposed low carbon fuel standard (LCFS).

MIT/RAND Study Concludes Three Types of Alternative Jet Fuel May Be Available in Commercial Quantities Over the Next Decade

Green Car Congress

The focus of the work was on alternative jet fuels that could be available commercially in the next decade using primarily North American resources. Canadian oil sands and Venezuelan VHOs have the largest potential of several hundred thousand barrels per day of jet fuel, but their use would result in increased GHG emissions.
