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. Credit: ACS, Brandt 2012. 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.

New study finds GHG emissions from palm oil production significantly underestimated; palm oil biofuels could be more climate-damaging than oil sands fuels

Green Car Congress

Based on visual interpretation of high-resolution (30 m) satellite images, a new study in the journal Global Change Biology: Bioenergy determined that industrial plantations covered over 3.1 When peat swamps are drained for agriculture, the peat begins to decompose, and is an enormous source of carbon emissions.

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. What Keystone XL would carry. Earlier post.) Greenhouse gas LCA analysis.

Researchers describe the “where” and “when” of life cycle emissions from gasoline and ethanol in the US

Green Car Congress

Researchers from the University of Minnesota have produced a spatially and temporally explicit life cycle inventory (LCI) of air pollutants from gasoline, ethanol derived from corn grain, and ethanol from corn stover for the contiguous US (the lower 48 states). Pollutant emissions from the gasoline life cycle do not vary appreciably by month.

Domestic production of crude oil has increased significantly, from approximately 5.5 million bpd in 2012 and 7.5 million bpd in 2010 to 6.5 million bpd.

National Low Carbon Fuel Standard study releases major Technical Analysis and Policy Design reports; providing a scientific basis for policy decisions

Very broadly, they found that an LCFS would buffer the economy against global oil price spikes, trim demand for petroleum, and lessen upward pressure on gas prices. Set a target of reducing the carbon intensity of gasoline and diesel by 10 to 15 percent by 2030. Create separate fuel pools for gasoline and diesel.
