Obama Power Plant Rules Spark 2016 Fight Over Climate Change

The president unveiled the plan at the White House Monday, calling it the “single most important step” the U.S. has taken to combat a major global threat. The Obama administration itself estimated the emissions limits will cost $8.4 billion annually by 2030, though the actual price won’t be clear until states decide how they would reach their targets. Republicans cast the measure requiring states to cut carbon dioxide emissions by 32 percent by 2030 as unnecessary and costly White House overreach that will raise energy costs for Americans.
