Carbon dioxide emissions from the production of shale oil and shale gas are higher than conventional oil production and a report for the European Union warns that increasing public concern about the adverse consequences of global warming may lead to opposition to oil shale development. [1] [3] Emissions arise from several sources.
An oil spill is the release of a liquid petroleum hydrocarbon into the environment, especially marine areas, due to human activity, and is a form of pollution.

The European Union's recent estimates that Canada's oil sands produce 22% more greenhouse gases (GHGs) than conventional crude have sent both sides into a war of words. Current and future industry ...
In the shadow of Canada's mega oil sands projects, smaller, technologically outdated facilities produce up to three times more emissions per barrel than the already high sector average- and rising ...
TransCanada's Keystone XL pipeline and the Canadian oil sands products it's meant to carry were already a couple of albatrosses in the public's eyes, but three recent developments just added more ...
Oil sand tailings or oil sands process-affected water (OSPW), have a highly variable composition and a complex mixture of compounds. [4] In his oft-cited 2008 journal article, E. W. Allen wrote that typically tailings ponds consist of c. 75% water, c. 25% sand, silt and clay, c.2% of residual bitumen, as well as dissolved salts, organics, and minerals.
This past quarter, Devon Energy , ConocoPhillips , and Suncor all posted better-than-expected results from their oil sands or thermal oil or bitumen operations (Side note: We sure have come up ...
