As if we needed any more convincing of how harmful pollution from tar sands oil production is, a new finding has indicated that the potential climate change emissions have increased by 5 times for the top 20 public companies working in that sector.
Processing tar sands produces quite a bit more greenhouse gas emissions compared with producing oil from other sources. Bitumen is a carbon-rich material that has to be refined by having the carbon removed by heating it to high temperatures. A byproduct called pet coke is generated that contains sulphur, heavy metals, and other impurities. It is sold to be burned in coal power plants in other countries where pollution regulations are less strict. Greenhouse gas emissions from pet coke are higher than coal.
This is all to say that oil from tar sands is dirty oil – some say the dirtiest.
FFI’s Director of Oil and Gas Research, Tom Francis, said: “Tar sands projects are particularly vulnerable to being abandoned due to the costly energy intensity of the extraction and refining processes. The overall emissions burden of gasoline refined from tar sands is more than 17% greater than that of gasoline refined from conventional crude oil, making it among the dirtiest feedstocks.”
If this information sounds sort of hopeless and depressing, there is something you can do. Don’t make investments in companies or funds that have strong ties to fossil fuel companies! The Fossil Free Indexes (FFI) has let us know that we can choose not to invest in them if we care about the planet and still invest in an index fund with good (actually, even better!) returns.
“Our clients have long been concerned about the environmental impact and the financial uncertainties associated with tar sands. Given the exceptional costs and risks associated with tar sands extraction, the substantial growth in tar sands reserves is striking.”
Socially responsible investing has grown over the years and so has green investing. According to the World Bank, the green bonds market expanded in 2013, and climate change awareness is an aspect of this type of investment.
It is possible to invest in a number of fossil-free opportunities.
The finding mentioned above about the potentially huge carbon emissions from the tar sands top 20 companies was based on research conducted using the same methodology utilized to rank the Carbon Underground 200.
So, if you have investments, are they the fossil-free kind, or are they contributing to global warming and climate change?

I don't like paywalls. You don't like paywalls. Who likes paywalls? Here at CleanTechnica, we implemented a limited paywall for a while, but it always felt wrong — and it was always tough to decide what we should put behind there. In theory, your most exclusive and best content goes behind a paywall. But then fewer people read it! We just don't like paywalls, and so we've decided to ditch ours. Unfortunately, the media business is still a tough, cut-throat business with tiny margins. It's a never-ending Olympic challenge to stay above water or even perhaps — gasp — grow. So ...
