Canada, faced with growing political pressure over the extraction of oil from its highly polluting tar sands, has begun courting China and other Asian countries to exploit the resource. The move comes as American firms are turning away from tar sands because of its heavy carbon footprint and damage to the landscape. Whole Foods, the high-end organic grocery chain, and retailer Bed Bath & Beyond last week both signed up to a campaign by ForestEthics to stop US firms using oil from Canadian tar sands. The Pentagon is also scaling down its use of tar sands oil to meet a 2007 law requiring the US government to source fuels with lower greenhouse gas emissions.
Major oil companies such as Shell are also coming under shareholder pressure to pull out of the Canadian projects. Earlier this year, Shell announced it was scaling back its expansion plans for the tar sands after a revolt by shareholders. Producing oil from the Alberta tar sands causes up to five times more greenhouse gas emissions than conventional crude oil, according to the campaign group Greenpeace.
In the most significant deal to date, the Canadian government recently approved a C$1.9bn (£1.5bn) investment giving the Chinese state-owned oil company PetroChina a majority share in two projects. Prime minister Stephen Harper said: "Expect more Chinese investment in the resource and energy sectors … there will definitely be more." China's growing investment in the tar sands is seen in Canada as a useful counter to waning demand for tar sands oil from the US, its biggest customer. The moves, which have largely gone unnoticed outside north America, could add further tension to efforts to try to reach a global action plan on climate change.
The state department envoy, Todd Stern, on Tuesday accused China of being "a bit ambiguous" in its commitments to reducing greenhouse gas emissions. Efforts to impose national carbon limits in the US have stalled in Congress, but a number of leading US firms are moving to reduce their carbon footprint by moving away from abandoning tar sands oil.
