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.

Oil sands GHG lifecycle study using operating data finds lower emitting oil sands cases outperform higher emitting conventional crude cases; a call for more sophisticated tools and reporting

Green Car Congress

Well-to-wheel (WTW) greenhouse gas emissions for in situ SAGD and surface mining pathways generated employing GHOST/TIAX/ GHGenius combination and comparison with SAGD, mining and conventional crude oil literature pathways (all results are on a HHV basis). WTW emissions for pathways vary by more than ±10% (e.g.,

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. 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.

Joint Canada/Alberta Implementation Plan for Oil Sands Monitoring begins summer air monitoring project

Green Car Congress

A comprehensive environmental field study to gather information on air contaminants in the Wood Buffalo region in northeast Alberta, Canada (home to major oil sands projects) will occur from 12 August to mid-September 2013. Evaluate high-resolution air quality models for use in the oil sands region. Earlier post.).

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.

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

Researchers at the University of Calgary (Canada) have developed the Petroleum Refinery Life-cycle Inventory Model (PRELIM). Put another way, “ the variability in GHG emissions in the refining stage that results from processing crudes of different qualities is as significant as the magnitude expected in upstream operations ”, they found.
