New study suggests reported PAH emissions in oil sands region greatly underestimated

Green Car Congress

Results from a new modeling assessment of contamination in the Athabasca Oil Sands Region (AOSR) suggest that officially reported emissions of polycyclic aromatic hydrocarbons (PAHs) in that region have been greatly underestimated. Accounting for evaporative emissions (e.g., Average emissions densities from Shen et al.

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

When peat swamps are drained for agriculture, the peat begins to decompose, and is an enormous source of carbon emissions. 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 —Miettinen et al.

U Calgary study finds oil shale most energy intensive upgraded fuel followed by in-situ-produced bitumen from oil sands

Green Car Congress

A team at the University of Calgary (Canada) has compared the energy intensities and lifecycle GHG emissions of unconventional oils (oil sands and oil shale) alongside shale gas, coal, lignite, wood and conventional oil and gas. How does this relate to the life cycle greenhouse gas (GHG) emissions intensity?

Researcher urges more effort on assessment of land and water impacts of oil sands production; reference point for other unconventional fuels

Green Car Congress

Bitumen production from the Canadian oil sands provides a point of reference that could be used to observe and better manage the land and water impacts of a rapid transition to unconventional fuels, suggests Dr. Sarah Jordaan of the Energy Technology Innovation Policy Research Group, Department of Earth and Planetary Sciences, Harvard University.

Two Lifecycle Studies Find Greater Range in GHG Emissions from both Conventional and Oil Sands Derived Crude Than Previously Shown; Oils Sands Emissions Comparable to Conventional Oil Production in Some Cases

Green Car Congress

A plot from the TIAX study of the ranges of well-to-wheel emissions for different types of crudes in different refinery areas in the US for gasoline production. The two studies represent the first detailed and more granular comparison of domestic, imported and oil sands crude processes in US refineries. Click to enlarge.

US State Department Issues Permit for Alberta Clipper Pipeline for Oil Sands Crude Delivery to US

Green Car Congress

The US State Department has issued a Presidential Permit to Enbridge Energy, Limited Partnership to enable construction of the Alberta Clipper pipeline for the transport of crude oil from the Canadian oil sands to US refineries. This week, the RFA happened to issue two pieces, each touching on the impact of oil sands production.

Ecofys report concludes current European regulations underestimating GHG reductions

Green Car Congress

Substituting biofuels for marginal fossil-based liquid fuels results in the avoidance of significant GHG emissions that are not currently accounted for in the European Renewable Energy Directive (2009/28/EC), according to a new analysis by the consultancy Ecofys. Both effects increase the carbon footprint of conventional oil.
