From the Associated Press:
Washington, D.C. - The Obama administration will unveil a plan Monday to cut earth-warming pollution from power plants by 30 percent by 2030, according to people familiar with the proposal.
The rule, when it becomes final a year from now, will set the first-ever national limits on the gases linked to global warming from the nation's power plants. They are the largest source of greenhouse gases.
It will also be a defining part of President Barack Obama's environmental legacy, which has revolved around global warming.
Environmental Protection Agency data shows the nation's power plants have reduced carbon dioxide emissions by nearly 13 percent since 2005, so they are about halfway to the target in the proposal.
The details were first reported Sunday by The Wall Street Journal.
