WASHINGTON — A federal judge late Thursday blocked construction of the disputed Keystone XL oil pipeline, saying the Trump administration “simply discarded” the effect the project would have on climate change.
The ruling by Judge Brian Morris of the U.S. District Court for Montana repudiates one of Donald Trump’s first acts as president. Two days after taking office, Trump signed an executive order approving the Keystone pipeline that had been blocked by former President Barack Obama because of environmental concerns.
In saying that no work can go forward until the government more fully reviews the pipeline’s environmental impact, the ruling tees up another potentially contentious legal battle over climate change with a president who dismisses mainstream science and whose administration is also seeking to block a landmark lawsuit on behalf of children asking the government to stop the rise of planet-warming gases.
The White House did not immediately respond to a request for comment.
Environmental groups hailed the decision as a major victory in the long-running battle over Keystone, which has spanned more than a decade and become a symbol of the political battle over climate change. The nearly 1,200-mile pipeline from TransCanada Corp. would carry about 800,000 barrels of petroleum a day from the Canadian oil sands to Gulf Coast refineries. Construction could have begun as early as next year.
Morris found that in reviving Keystone, the Trump administration did not adequately account for how a decline in oil prices might affect the pipeline’s viability. In addition, the government’s analysis did not fully study the potential for oil spills or the cumulative effects of greenhouse gas emissions from the Keystone pipeline in combination with a pipeline approved in 2009, the Alabama Clipper.
The ruling specifically takes the Trump administration to task for failing to address the Obama administration’s arguments about climate change, including the need to keep rising global temperatures at safe levels as a basis for denying the pipeline permit.
When Obama rejected the Keystone permit in 2015, he was weeks away from negotiating an international global warming accord in Paris, and the administration also argued the pipeline would undercut U.S. leadership in curbing global reliance on fossil fuels.
The Trump administration failed to present facts or a “reasoned explanation” to those arguments as required, Morris wrote.
