Just like with “clean coal”, the same type of euphemistic hope is being stuck on tar sands oil. Those invested in the industry were even saying it can be “low carbon”. That was based in part on assuming carbon capture and storage (CCS) will save the day and allow us to use the dirtiest oil on earth and feel OK about it. A new report by investors says wait a minute — we can’t count on CSS after all.
For environmental reasons, tar sands oil will never be OK to use, even if CCS works, which is debatable. It’s very difficult to imagine low carbon tar sands oil due to the nature of extracting the oil from dirt and sand and rock. They also have to destroy old forests and completely clear the land of vegetation to get at the oil sands. Lots of chemicals and billions of gallons of water are used.
Tar sands oil is mainly from Alberta, and if Canada is to live up to its carbon budget, it won’t be able to continue to mine the tar sands. That would be the best thing for Canada — and the world — anyway. It’s no secret how devastating the tar sands mining is to the environment, and how dangerous it is to human health, especially to the people downriver from the mining. The bottom line is: exploiting and destroying Canadian forests and land for this tar sands oil is highly carbon intensive.

Report Slams Low-Carbon Tar Sands Myth (Business Green)
Even under the most optimistic scenarios for CCS development, the projected emissions from tar sands developments would be greater than Canada’s entire 2050 carbon budget.
The potential rollout of carbon capture and storage (CCS) should not be used to justify the continued expansion of Canada’s controversial tar sands industry, according to a major investor-backed report released yesterday.
In August, Hillary Clinton approved the U.S. pipeline carrying tar sands oil from Canada into Minnesota, called The Alberta Clipper.
From the industry report:
The production of tar sands oil is a highly energy intensive process and emits on average three times more CO2 than conventional oil production.
The report, from Co-operative Financial Services and WWF-UK, challenges oil industry and Canadian government claims that fitting emerging CCS technologies to the plants used to extract and refine oil from tar sands will sufficiently limit the emissions generated from the energy-intensive process.
The study found that the amount of CO2 emitted during production needs to be reduced by about 85 per cent to make tar sands oil comparable with conventional oil – way beyond the most optimistic forecasts for CCS.
It added that even under the most optimistic scenarios for the application of CCS, the projected production emissions from tar sands developments would be greater than the whole of Canada’s 2050 carbon budget were it to stick to its existing emission-reduction targets.
It also calculated that the maximum potential of CCS would not reduce life cycle emissions of tar sands oil to levels needed to meet emerging international low-carbon fuel standards, such as those adopted in California and the EU.
Paul Monaghan, head of social goals at Co-operative Financial Services, said the report showed that “even the most wildly optimistic scenarios for the development of CCS fail to bring emissions down to those of today’s conventional fossil fuels”.
He added that the research further highlighted the investment risks associated with tar sands projects that remain largely incompatible with global efforts to curb carbon emissions.
The Co-operative Group has been campaigning against carbon-intensive investments such as tar sands projects, arguing that the likely introduction of carbon legislation and emission pricing schemes mean they present significant long-term risks for investors.
Last year, the company released research showing that oil produced from tar sands emits on average three times more CO2 through its life cycle than conventional oil. It also warned that exploiting Canada’s tar sands alone could increase global atmospheric CO2 concentrations by more than 10 parts per million.
David Norman, director of campaigns at WWF-UK, warned that the continued focus on fitting CCS to tar sands plants was “diverting money away from projects that will help meet the global energy demand without damaging the climate”. He added that “Canada should invest in other low-carbon technology and stop the expansion of tar sands.”
