Midwest Oil Refineries Gobble Up Canadian Tar Sands, Spew Greenhouse Gasses

Midwest oil refineries are gobbling up more and more crude oil from Canadian tar sands and are set to belch out up to 40 percent more greenhouse gas emissions in the next decade.

According to the Chicago Tribune, oil refineries across the Midwest are set to expand (see graphic) and are planning on processing heavy crude oil from Canadian tar sands, part of an industry-wide trend to buy more Canadian crude.

Canada has huge reserves of tar-soaked clay and sand known as “tar sands” lying under the swampy forests of northern Alberta. At today’s higher oil prices, these tar sands are seen as a profitable and reliable source of oil but they require environmentally devastating mining processes and vast amounts of energy to extract. The resulting heavy crude oil requires also more energy to process at refineries. Researchers have calculated that refining the Canadian tar sands crude produces 15 percent to 40 percent more carbon dioxide emissions than conventional oil, the Tribune reports. (Editors note: I believe this does not include “upstream” emissions resulting from the energy intensive mining processes.)

As the Tribune points out, with no greenhouse-gas regulations currently in place, oil companies face no costs for the extra pollution they will churn into the atmosphere.

“This is a glaring example of how our energy policy and climate policy are at cross purposes,” said Judi Greenwald, director of innovative solutions at the Pew Center on Global Climate Change. “Companies are making decisions that really don’t make sense on a national level when you fail to take climate change into account.”

Increasing reliance on environmentally destructive and carbon-intensive tar sands is a very worrying trend and presents a glaring inconsistency as Midwestern governors, leading presidential candidates and the US Congress all work on policies that will help drive greenhouse gas emissions reductions.

“If carbon isn’t considered in these huge investments, we are going to be stuck with a tremendous burden,” said Henry Henderson, a former Chicago environment commissioner who now heads the Natural Resources Defense Council’s Midwest office.

Like coal-to-liquids synthetic fuels, this un-conventional source of fuel may help reduce reliance on Middle Eastern oil, but only exacerbates global warming. Comprehensive global warming regulations are needed quickly so that decisions about alternative fuels incorporate both concerns about energy independence AND global warming and do not simply trade one huge problem – our oil addiction – for another – accelerating climate change.

    This, at a time when the MW governors have “committed” to regulating and reducing CO2 on a regional level… We will have a lot of work ahead of us to make sure that this Midwestern Greenhouse Gas Accord isn’t just a load of rhetoric and actually addresses the problem.

    There was a really exciting public hearing on the Marathon expansion in Detroit.

    I’d like to know what a lot of the communities where the expansions are slated for taking place are like. Here in Detroit, the Marathon refinery is located in a Black and Latin@ neighborhood next to several schools. This is being treated as a huge environmental justice issue here and I’m interested in finding ways that students can link issues and efforts with community leaders working on stopping the expansion.

    This is going to be a huge environmental justice issue in the Midwest, I’d really like to see stuff from student groups hooking up with community leaders in their neighborhoods to take on these expansions.

    Has anyone compared the increased CO2 emissions from the extracting and refining of Canadian tar sand oil to the emissions produced by freighters that import the same volume of crude to the US?

    Since the 1960′s the United States has done everything in its power to take science out of everything. Actually, to make it bad because some feeling might get hurt. Why? So flim flam artists can sell any ridiculous idea that they can to make huge profits.

    I am all for alternate energy. But until a real scientific breakthrough is made to make it cost effective to the middle class, get real. We need oil and all of its byproducts to continue growth.

    Greenie weenies – ever see how many green house gasses a volcano spews? How about over Yellowstone? The methane bubbling up from the ocean floor?

    Where’s the science in this. Or are feel good speeches all you are going to base your opinion on? (Watch Gore on his jet flying as a single passenger to Europe to get into a huge truck and drive all over the place).

    Well, I guess we should stop using the oil sands! It’s settled! I’m sure the Canadians won’t find another oil-hungry buyer like China or India. They’ll say, oh well, I guess the sands are too carbon-intensive to prove useful. Gosh, if the US says they won’t buy it, it’s time to close up shop!

    There is a good website at http://www.canadasoilsands.ca that provides a lot of information and links to other groups on the oilands.
