WASHINGTON — As President Barack Obama worked to hammer out a global climate agreement in Paris, Republicans in Congress moved to block his plan to force steep cuts in greenhouse gas emissions from U.S. power plants.

The House passed two resolutions Tuesday disapproving Obama’s power-plant rules and rendering them inoperative. A measure blocking an Environmental Protection Agency rule for existing power plants was approved 242-180, while a measure blocking a rule on future power plants was approved 235-188.

The votes come after the Senate approved identical motions last month under a little-used law that allows Congress to block executive actions it considers onerous. The measures now go to the White House, where they face almost-certain vetoes. Just four Democrats sided with Republicans to support the measures, which fell far short of the numbers needed to override a veto in both the House and Senate.

Rep. Ed Whitfield, R-Ky., said GOP lawmakers were forcing a vote on the climate rule to “send a message to the climate conference in Paris that in America, there’s serious disagreement with the policies of this president.”

House Majority Leader Kevin McCarthy, R-Calif., said Obama wants to reduce carbon emissions, but his policies will kill jobs, increase electricity costs and decrease the reliability of the U.S. energy supply.

And Rep. Jeff Duncan, R-S.C., said he wished Obama took the threat posed by “radical jihadists” such as the Islamic State as seriously as he takes what Duncan called a “pseudoscientific threat” posed by climate change.

Rep. Ryan Zinke, R-Mont., voted for both resolutions.

“I believe Montana knows how to best manage our power and our resources, much better than unelected bureaucrats in Washington, D.C, do.,” Zinke said in a news release. “Our state has already reduced our emissions rates without the federal government getting involved. The plan will kill good-paying union jobs and drive up costs for Montana families and small businesses.”

Zinke continued: “If our governor decides to comply with this supposed ‘clean’ power plan, Montanans will suffer. All of Colstrip will have to close, essentially closing the entire town. Over seven thousand jobs will be lost. Energy costs for consumers will skyrocket. Personal income will be devastated. And, even more concerning, our state’s economic activity will decline by almost one billion dollars by 2025.”

Democrats countered that the power-plant rules were important steps to slow global climate change that is already causing real harm through increased droughts, wildfires, floods and more severe storms.

Rep. Frank Pallone, D-N.J., said it was regrettable that Republicans were trying to block the power-plant rules even as officials from more than 190 nearly countries and many of the world’s largest private companies gathered in Paris to work out details of a global agreement to reduce greenhouse gas emissions.

The global agreement “will prevent us from further overheating the earth and causing major disruptions to people’s lives, their property and to the global economy,” Pallone said. “We know that (climate change) will endanger our children’s future if we don’t act now.”

The Obama administration’s Clean Power Plan requires states to cut carbon emissions by 32 percent by 2030, based on emissions in 2005. Each state has a customized target and is responsible for drawing up an effective plan to meet its goal.

The EPA says it has authority to enact the plan under the Clean Air Act.

Twenty-five mostly Republican states, led by Texas and West Virginia, are contesting the plan in court, calling it an unlawful power grab that will kill jobs and drive up electricity costs. Several utilities, the National Mining Association and the nation’s largest privately owned coal company also are suing the EPA.

GOP lawmakers challenged the administration’s action under the little-used Congressional Review Act, which allows Congress to block executive actions with simple majority votes. The maneuver is subject to a presidential veto and has rarely been successful.

The White House issued a veto threat last month, saying the resolutions undermine public health protections of the Clean Air Act and “stop critical U.S. efforts to reduce dangerous carbon pollution from power plants.”

Speaking in Paris Tuesday, Obama said parts of a global climate agreement should be legally binding. His declaration was both a boost to climate negotiators seeking a tough accord and a challenge to Republicans in Congress, many of whom reject the idea of global warming.

House Speaker Paul Ryan, R-Wis., said Republicans were in step with the American people, who want jobs and economic growth.

“I think when you weigh the costs and the benefits against these so-called legally binding obligations they don’t add up,” Ryan told reporters. “I think it’s very clear people want jobs.”
