Shell and BP have been warned by investors that their involvement in unconventional energy production such as Canada's oil sands could turn out to be the industry's equivalent of the sub-prime lending that poisoned the banking sector and triggered the current financial crisis.
"The recent banking crisis has shown how the financial markets can totally misjudge both the risks and values inherent in company balance sheets," he said. "Oil companies depend on oil reserves for their market values. BP and Shell are two of our most trusted stocks, but it is a shocking fact that 30% of Shell's oil reserves are in tar sands.
"This report unveils how dangerous this approach is. There is a good chance that tar sands could be to the oil industry what sub-prime lending was to the banking sector."
