EPA’s use of regulations to curb climate change gases upheld

WASHINGTON: A federal appeals court upheld the first-ever US government regulations aimed at reducing the gases blamed for global warming.

The rules, which had been challenged by industry groups and several states, will reduce emissions of six heat-trapping gases from large industrial facilities such as factories and power plants, as well as from automobile tailpipes.

A three-judge panel of the US Court of Appeals in Washington said that the Environmental Protection Agency was “unambiguously correct” in using existing federal law to address global warming, denying two of the challenges to four separate regulations and dismissing the others.

The ruling is perhaps the most significant to come out on the issue since 2007, when the Supreme Court found that greenhouse gases could be controlled as air pollutants under the Clean Air Act, a step the Bush administration had resisted.

It also lands during a presidential election year where there are sharp differences between the two candidates when it comes to how best to deal with global warming.

President Barack Obama’s administration has come under fierce criticism from Republicans, including Mitt Romney, the party’s almost certain presidential nominee, for pushing ahead with the regulations after Congress failed to pass climate legislation. In 2009, the EPA concluded that greenhouse gases endanger human health and welfare, triggering controls on automobiles and other large sources. But the administration has always said it preferred to address global warming through a new law.

EPA Administrator Lisa Jackson called the ruling a “strong validation” of the approach the agency has taken.

The court “found that EPA followed both the science and the law in taking common-sense, reasonable actions to address the very real threat of climate change by limiting greenhouse gas pollution from the largest sources,” Jackson said in a statement.

Carol Browner, Obama’s former energy and climate adviser, said the decision “should put an end, once and for all, to any questions about the EPA’s legal authority to protect us from dangerous industrial carbon pollution,” adding that it was a “devastating blow” to those who challenge the scientific evidence of climate change.

At a meeting in the state of New Hampshire last year Romney, said it was a mistake for the EPA to be involved in reducing emissions of carbon dioxide, the chief greenhouse gas.

“My view is that the EPA is getting into carbon and regulating carbon has gone beyond the original intent of the legislation, and I would not go there,” he said.

The court seemed to disagree with Romney’s assessment when it denied two challenges to the administration’s rules, including one arguing that the agency erred in concluding greenhouse gases endanger human health and welfare.

Lawyers for the industry groups and states argued that the EPA should have considered the policy implications of regulating heat-trapping gases along with the science. They also questioned the agency’s reliance on a body of scientific evidence that they said included significant uncertainties.

The judges – Chief Judge David Sentelle, who was appointed by Republican President Ronald Reagan, and David Tatel and Judith Rogers, both appointed by Democrat Bill Clinton – flatly rejected those arguments.

“This is how science works,” the unsigned opinion said. “EPA is not required to re-prove the existence of the atom every time it approaches a scientific question.”
Industry groups vowed to fight on.
