Arctic

Earlier this month, after more than 100,000 of you asked Cairn Energy to open up its Arctic oil spill response plan to public scrutiny, the government of Greenland stepped in and published it.

The verdict is now in. Veteran marine biologist and international oil spill expert Professor Richard Steiner has completed a review of the plan and, well, it's no wonder Cairn didn't want you to see it.

This morning, Cairn Energy published its half-yearly results. There isn't much for the company to shout about in there; halfway through their 2011 drilling season, they have yet to find any oil in the Arctic.

Shell has apologised for the North Sea oil spill and for its own lack of transparency saying: "The fact is something has gone wrong here, so whatever risk assessment we made about the condition of these pipes has proven to be wrong."
