Average carbon intensity of oil sands production has dropped ~36% in last 40 years; still 12-24% higher than conventional oil CI

Green Car Congress

The carbon intensity (CI) of Alberta oil sands production has significantly decreased over the last 40 years, according to a new study by a team from Stanford University published as an open access paper in the journal Environmental Research Letters.

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

Mha (20%) of the peatlands of Peninsular Malaysia, Sumatra and Borneo in 2010, surpassing the area of Belgium and causing an annual carbon emission from peat decomposition of 230–310 Mt CO 2 e. Slightly more than half of the GHG emissions for these biofuels in the EPA’s analysis came from land use change. Earlier post.). —Dr.

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.

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). Efficiencies and emissions factors reported are for year 2010.

ExxonMobil Outlook: 35% growth in energy demand by 2040; hybrids to account for ~50% of new vehicle sales

Green Car Congress

By 2040, hybrids are expected to account for about 35% of the global light-duty vehicle fleet, up from less than 1% in 2010. In 2010, about 75% of the world’s vehicles were in OECD countries. liters per 100 km) in 2010. China will see the largest increase—more than 4 million oil-equivalent barrels per day.

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. In the US, GHG emissions from refineries in 2010 represented nearly 12% of US industrial sector emissions or 3% of the total US GHG emissions. Click to enlarge.

ExxonMobil: global GDP up ~140% by 2040, but energy demand ~35% due to efficiency; LDV energy demand to rise only slightly despite doubling parc

Green Car Congress

As the world population increases by the estimated 30% from 2010 to 2040, ExxonMobil sees global GDP rising by about 140%, but energy demand by only about 35% due to greater efficiency. The Outlook for Energy identifies a significant evolution in the trade of oil and other liquids. Click to enlarge. Outlook for Energy.
