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.

Ecofys report concludes current European regulations underestimating GHG reductions

Green Car Congress

The study was commissioned by the European Oilseed Alliance (EOA), the European Biodiesel Board (EBB) and the European Vegetable Oil and Proteinmeal Industry (FEDIOL). In addition, they argue, biofuels should not just be compared to the average performance of gasoline or diesel but with the fossil fuels they most likely replace—i.e.

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).

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. Annual GHG emissions from a large refinery are comparable to the emissions of a typical 500 MW coal-fired power plant. Credit: ACS, Abella and Bergerson. Click to enlarge.

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. Energy-related CO 2 emissions.
