US President Barack Obama rejected the Keystone XL pipeline on Friday, saying the project would have damaged the US ability to lead on efforts to tackle climate change ahead of Paris climate talks, dpa reported. Obama called newly installed Canadian Prime Minister Justin Trudeau to inform him of the decision. He said Trudeau expressed disappointment but promised the two countries would continue to cooperate closely on energy and climate-change issues. The proposed Keystone XL pipeline was slated to carry oil from Canada's tar sands in Alberta to the Midwestern state of Nebraska, where an existing pipeline would carry the Canadian oil to refineries in Texas. The project called for the construction of a 1,900-kilometre-long pipeline that would pump 830,000 barrels of oil a day.
