WASHINGTON -- President Barack Obama today will announce a long-awaited federal strategy that not only is expected to sharply cut the countrys greenhouse gas emissions but also will address the sweeping effects of climate change already occurring in many communities.
Obama today in a speech at Georgetown University will announce a national plan to reduce carbon pollution, including a plan that has at its centerpiece the use of the Environmental Protection Agency's authority to regulate greenhouse gas emissions at older power plants. Those existing power plants are estimated to be of 40 percent of the emissions that lead to global warming.
Obamas move, long awaited by environmentalists, makes good on a pledge in his second inaugural address to respond to climate change. At the time, he cast it as a moral obligation and warned that failing to take action would betray our children and future generations. Its not just a responsibility to his fellow Americans, Obama said, but to all posterity. Last week in Germany, he called it the global threat of our time.
Environmental groups have been pressuring Obama to act on the promises laid out in that inaugural speech, which included a pledge to take executive action if Congress did not act. The Natural Resources Defense Council launched ads featuring actor Robert Redford calling on the president to act on the courage of his convictions.
Obama is "finally putting action behind his words," said Michael Brune, executive director of the Sierra Club. The president is "stepping up to reduce the climate-disrupting pollution that is destabilizing our climate while threatening our economy and endangering our communities and families with extreme weather and dramatic sea level increases," Brune said.
Until now, there has not been a cohesive strategy to reduce emissions to meet U.S. targets, said Andrew Steer, president of the World Resources Institute, an environmental think tank. Its important for private investors and ordinary people to have a clear sense of where the government is heading, he said.
President Obama is really resetting the climate agenda tomorrow. And its a wonderful thing to see that he is reclaiming this issue, Steer said.
The administration, through the EPA, already has drafted rules that curtail emissions at new power plants. What it hasnt done yet is issue rules that apply to existing power plants.
Those rules are likely to be the most controversial piece of the proposal in the presidents speech, since many of the dirtiest, carbon-intensive power plants are fueled by coal. Regional energy interests, among others, are likely to object.
And they could be expensive. That Natural Resources Defense Council estimates at least $4 billion for utilities to comply with new regulations. The group estimates as much as $25 to 60 billion in benefits, however, including the health benefits of switching to energy sources that produce less soot.
Courts have determined that carbon emissions are a pollutant under the Clean Air Act, and that the EPA has the authority to pursue regulation of them. A number of major environmental groups have given the White House plans that outline what sort of legal authority they think the agency has to act.
The U.S. has more than 1,142 coal-fired plants and 3,967 gas-fired plants across the country, according to the Edison Electric Institute, a utility trade group that represents many of the nations power producers. About 37 percent of all of U.S. electricity is generated from coal. About 30 percent came from natural gas in 2012. Natural gas, because it is cheaper, has been rapidly overtaking coal as a preferred fuel.
