标题:The greening of Canada? Feb 23rd 2009 From Economist.com Stephen Harper looks to Washington, not Alberta DESPITE being two of the most profligate energy users on the planet, the United States and Canada have spent little time over the last eight years discussing what they might do together to combat climate change and protect the environment. That changed on February 19th, when President Barack Obama made his first post-inauguration trip abroad to meet Stephen Harper, Canada’ s prime minister. The environment was one of just three topics on their official agenda. Mr Obama seems the more committed environmentalist; clean energy and energy reduction figure prominently in his stimulus package. Mr Harper is a more recent convert to the green cause and it is not yet clear he has been fully won over. He is torn between his allegiance to his adopted province of Alberta, where Canada’s tar sands are located, and the need to align Canada’ s policies with those of America, which buys most of Canada’s energy exports. As long as George Bush remained in office, Mr Harper did not have to choose between the two, but a new president with decidedly greener views will force his hand. The tar sands, which account for about half of Canada’s crude oil exports (almost all of which go to America, along with much of Canada’s natural gas, hydro-electric power and uranium), were under attack by green groups and some American policymakers long before the change of administration. Steaming the heavy oil out of the ground, or mining and processing the tarry sand, require large amounts of energy and water, and the deforestation of vast tracts of boreal forest. The federal and Alberta governments have resisted imposing environmental rules that would impede tar-sands development. This stance is now shifting. Just days after the American election, the Canadian prime minister proposed a continental cap-and-trade system to control carbon emissions—something the oil industry in Canada adamantly opposed. Earlier this month, the Alberta government brought out a 20-year plan for the greening of the tar sands, which, while light on details, showed more than the usual resolve. Even more surprising was the decision in February of the federal and Alberta governments to charge Syncrude, a large tar-sands processor, with offences under environmental and bird-protection laws for the deaths of 500 ducks in one of the company’s tailing ponds last April. Mr Harper and his advisors are also aware that while Mr Bush blocked states’ efforts to regulate greenhouse-gas emissions (California and Vermont, for instance, both wanted to set a carbon standard for transport fuels), Mr Obama may permit such state-by-state laws. And Canada is still fighting for an exemption from a rule inserted into the 2007 Energy Independence and Security Act that bars the American government from buying fuels whose production causes more greenhouse-gas emissions than conventional petroleum sources, as producing oil from tar sands does. At their meeting in Ottawa, Messrs Harper and Obama agreed to collaborate on the development and use of clean energy—boilerplate stuff. But they also discussed broader collaboration in the future, including matching their countries’ environmental rules. At first glance, this is bad news for tar-sands producers, already struggling with the slump in oil prices from over $140 a barrel last July to less than $40 today. During that time projects worth an estimated $80 billion have been cancelled or postponed. Some people in the industry still believe that America ’s need for oil is so great that it cannot afford to reject oil, however dirty, from a friendly, secure supplier. But with every green pronouncement from Mr Obama, this becomes a fainter hope. There is a bright side. Stimulus money is pouring out of Washington and Ottawa, some of it already earmarked for research and technology to help the oil industry produce cleaner fuels. Both Mr Obama and Mr Harper made particular mention of carbon capture and sequestration, an unproven and expensive technology that could eventually be used on the coal plants that produce about 70% of American electricity, or on the upgraders and refineries in the tar sands. If the industry is finally and reluctantly forced to go green because of Mr Obama, at least taxpayers will help pay for it. http://www.economist.com/daily/columns/greenview/displaystory.cfm?story_id=13167651&fsrc=nwl 新闻来源: (需有正确连结) -- --
