The Obama administration faces a test of its environmental credentials in deciding whether to approve a pipeline carrying greenhouse gas-intensive oil sands fuel from Canada into the US.
Hillary Clinton, secretary of state, is expected to decide as early as this month whether to approve the Alberta Clipper, a 1,000-mile pipeline designed to carry up to 800,000 barrels a day of fuel from Canada’s vast oil sands.
Environmentalists say doing so would be at odds with the green economy pledged by the administration.
