"WASHINGTON/CALGARY -- Canada is running out of time to offer U.S. President Barack Obama a climate change concession that might clinch the controversial Keystone XL oil pipeline, as the country's energy industry continues to resist costly curbs on greenhouse gas emissions."
"Two years of negotiations between the Canadian government and the energy sector to curtail carbon pollution have not produced an agreement. Oil producers have balked at anything more than the 10-cents-a-barrel carbon tax imposed by the province of Alberta.
Late last month, Environment Minister Leona Aglukkaq pointed to "good progress" in the talks but was unable to say when a resolution might come."
