US President Barack Obama has rejected the proposed Keystone XL oil pipeline from Canada in a victory for environmentalists who campaigned against the project for more than seven years.
Obama told a press conference the pipeline would not make a “meaningful long-term contribution to our economy”.
He said it would not reduce gasoline prices, and shipping “dirtier” crude from Canada would not increase US energy security.
The denial of TransCanada Corp’s more than 800,000 barrels per day project will make it more difficult for producers to develop the province of Alberta’s oil sands.
It could also put the United States in a stronger position at global climate talks that start in Paris on November 30 in which countries will aim to reach a deal to slow global warming.
US Secretary of State John Kerry, who determined the pipeline was not in the country’s interest before Obama’s final decision, said approving Keystone “would significantly undermine our ability to continue leading the world in combating climate change.”
Keystone XL would have linked existing pipeline networks in Canada and the United States to bring crude from Alberta and North Dakota to refineries in Illinois and, eventually, the Gulf of Mexico coast.
TransCanada first sought the required presidential permit for the cross-border section in 2008 but the proposal provoked a wave of environmental activism that turned Keystone XL into a rallying cry to fight climate change.
TransCanada and other oil companies said the pipeline would have strengthened North American energy security, created thousands of construction jobs and helped relieve a glut of oil.
But since 2008 the United States has experienced a domestic drilling boom which has boosted oil production 80 percent and contributed to a slump in US oil prices from above $100 a barrel to about $44.
Newly sworn in Canadian Prime Minister Justin Trudeau, a supporter of Keystone, voiced disappointment but said the Canada-US relationship “is much bigger than any one project.”
