A team at the University of Calgary (Canada) has compared the energy intensities and lifecycle GHG emissions of unconventional oils (oil sands and oil shale) alongside shale gas, coal, lignite, wood and conventional oil and gas. This is not the same as crude oil occurring naturally in shales, as in the Bakken.

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.

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).

The five different fuel groups were those derived: from conventional petroleum; from unconventional petroleum; synthetically from natural gas, coal, or combinations of coal and biomass via the FT process; renewable oils; and alcohols. Certain HRJ and FT fuels are able to reduce the GHG emissions from aviation. million bpd.

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.

Building on LCFS policies already adopted in Europe, British Columbia, and California, the researchers looked at potential costs and benefits of reducing the carbon intensity of transportation fuels by 10 to 15 percent by 2030. Create separate fuel pools for gasoline and diesel. We did not shy away from controversy.

Last year, more than two-dozen advanced biofuel companies, joined by researchers and investors under the aegis of the New Fuels Alliance, submitted a letter to the California Air Resources Board (ARB) questioning ARB’s intent to include ILUC—or any kind of indirect effects enforcement against biofuels—as part of the regulation.
