New lifecycle analysis of WTW GHG emissions of diesel and gasoline refined in US from Canadian oil sands crude

Green Car Congress

In a new, comprehensive study, a team from Argonne National Laboratory, Stanford University and UC Davis ITS has estimated the well-to-wheels (WTW) GHG emissions of US production of gasoline and diesel sourced from Canadian oil sands. g CO 2 e/MJ for US conventional crude oil recovery. This range can be compared to ∼4.4

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

The majority (62%) of the plantations were located on the island of Sumatra, and more than two-thirds (69%) of all industrial plantations were developed for oil palm cultivation, with the remainder mostly being Acacia plantations for paper pulp production. Earlier post.). —Dr.

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.

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.
