The EPA rules under attack on Friday would reduce greenhouse gas emissions from power plants by 32% by 2030 on 2005 levels, delivering the biggest single cut in America’s carbon pollution. The EPA is being sued by 24 US states and the National Mining Association , who oppose Obama 's clean energy plan to reduce carbon pollution from power plants . Both lawsuits were filed on Friday , and oppose the EPA rules to reduce greenhouse gas emissions from power plants 32 % by 2030 ( from 2005 levels ) , sending a powerful message ahead of the Paris climate change conference in just over a month 's time . The White House has said it would veto any effort in Congress to repeal the EPA rules , however , the Republicans are also trying to disrupt Obama 's clean energy plans by blocking the US from signing a climate deal in Paris , without it being ratified by the Senate .
