Canada’s largest oilsands companies have formed a new advocacy group they say will help to advance the sustainable development and operation of their industry. The Oil Sands Alliance was established Jan. 1, with membership consisting of oilsands producers Suncor Energy Inc., Cenovus Energy Inc., Imperial Energy Ltd., Canadian Natural Resources Ltd. and ConocoPhillips. It is not clear whether the new organization will be involved in political lobbying or how exactly it will be structured.
