Republicans and business and labor groups have urged Obama to approve the pipeline to create thousands of jobs and move toward North American energy independence.
The pipeline is also strongly supported by Democrats in oil and gas-producing states, including Sens. Mary Landrieu of Louisiana, Mark Begich of Alaska and Mark Pryor of Arkansas. All face re-election this year and could be politically damaged by rejection of the pipeline. Republican Mitt Romney carried all three states in the 2012 presidential election.
The 1,179-mile pipeline would travel through the heart of the United States, carrying oil derived from tar sands in western Canada to a hub in Nebraska, where it would connect with existing pipelines to carry more than 800,000 barrels of crude oil a day to refineries in Texas. It would cross Montana and South Dakota before reaching Nebraska.
An existing spur runs through Kansas and Oklahoma to Texas.
Canadian tar sands are likely to be developed regardless of U.S. action on the pipeline, the report said, and other options to get the oil from Canada to Gulf Coast refineries — including rail, trucks and barges — would be worse for climate change.
State Department approval is needed because the pipeline crosses a U.S. border. The Environmental Protection Agency and other departments will have 90 days to comment before State makes a recommendation to Obama on whether the project is in the national interest. A final decision by the government is not expected before summer.
Senate Minority Leader Mitch McConnell, R-Ky., said the report “once again confirms that there is no reason for the White House to continue stalling construction of the Keystone XL pipeline.” Addressing Obama, McConnell said: “Mr. President, no more stalling, no more excuses. Please pick up that pen you’ve been talking so much about and make this happen. Americans need these jobs. “
However, a top official at the Natural Resources Defense Council, an environmental group, said the report gives Obama all the information he needs to reject the pipeline.
“Piping the dirtiest oil on the planet through the heart of America would endanger our farms, our communities, our fresh water and our climate. That is absolutely not in our national interest,” said Susan Casey-Lefkowitz, the NRDC’s international program director.
In Canada, Natural Resources Minister Joe Oliver welcomed the report and said of the pipeline: “The benefits to the U.S. and Canada are clear. We await a timely decision.”
“The choice for the United States is clear: oil supply from a reliable, environmentally responsible friend and neighbor or from unstable sources with similar or higher greenhouse gas emissions and lesser environmental standards.”
The new report comes only days after Obama’s State of the Union address, in which he reiterated his support for an “all-of-the-above” energy strategy that embraces a wide range of sources, from oil and natural gas to renewables such as wind and solar power.
The remarks were a rebuff to some of his environmental allies who argued that Obama’s support of expanded oil and gas production doesn’t make sense for a president who wants to reduce pollution linked to global warming.
Obama blocked the Keystone XL pipeline in January 2012, saying he did not have enough time for a fair review before a looming deadline forced on him by congressional Republicans. That delayed the choice for him until after his re-election.
