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.

Study Finds Water Use for Switchgrass Ethanol Production Approximately the Same as for Gasoline

Green Car Congress

Consumptive freshwater use for ethanol and petroleum gasoline production. In many cases, the Argonne team noted, crude oil production is increasingly water dependent. Competing uses strain available water resources and raise the specter of resource depletion and environmental degradation. Data: Wu, ANL/ESD/09-1.

New petroleum refining lifecycle model finds the variability in GHG emissions from refining different crudes as significant as magnitude expected in upstream operations

Green Car Congress

Comparison of GHGenius, JACOBS, TIAX, and the new PRELIM gasoline greenhouse gas (GHG) estimates using base case estimates and variations from the scenario analysis. The configurations are differentiated by the presence of gas oil hydrocracking; fluid catalytic cracking (FCC); delayed coking; and residual hydrocracking.

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). the contiguous US).

IHS CERA meta-analysis finds lifecycle GHG emissions for fuel produced solely from oil sands crude average 11% higher than from average crude refined in the US; high variability

Green Car Congress

Average values for WTW GHG emissions for oil sands and other crudes, tight boundary. When the oil sands products refined in the United States are considered—a mixture of oil sands and lower-carbon blending components—the GHG emissions are, on average, 9% higher than the average crude processed in the US.

HEI report identifies potential health consequences from new vehicle fuels and technologies; recommended actions

Green Car Congress

The new SCET report reviews a range of new technologies and fuels, from improved internal combustion engines, to hybrid and other electric drive technologies, to existing and new bio- and other types of fuels. Hybrid, all-electric drive, and fuel cell technologies are likely to see substantial market penetration by the end of this decade.
