In The National today, we take a look at the lengths to which some big oil companies now go to , and along with that, their public images.

Click on the cute green camel to check out what else the company is doing to improve the environment. Yes, the image is emotionally manipulative, but such is the case with all advertising. On the other side of the world in Canada's great boreal forest, , which extracts oil sands from the worlds biggest open pit mines, is returning some of its mined-out sites to as close to their original condition as is humanly possible. Big oil companies, whether state-owned or private sector, are seldom thought of as environmental champions, yet they increasingly employ environmental experts who are passionate about their life's work.
