We know tar sands are destructive, bad for the climate, and expensive to exploit. But could they also be a colossal financial liability for BP and Shell?
If, in the runup to Copenhagen, you have a sneaking suspicion that world leaders might still be more attached to the realpolitik of energy than the green-tinged adoption of strong climate policy, a new report from Greenpeace, Platform and Oil Change International may provide a glimmer of hope.
The suspicion is that whatever grand statements are made by the Obamas, the Lulas or the Browns of the world as they thrash out their meta-climate policy at Copenhagen, for the moment they're going to remain much more motivated by ‘energy security' than greenhouse gas stabilization.
