Sweeping new regulations on electric power plants announced by the EPA on Monday will trigger lawsuits from states and industry groups, and the U.S. Supreme Court will probably get the final say.

The new regulations are part of the Obama administration’s goal to reduce carbon emissions from power plants by 30 percent by 2030. The administration says the health and environmental benefits of such reductions are worthwhile, but the mandatory reductions will likely cause many coal-fired power plants to be shut down and will drive-up energy prices across the country.

Opposition from the coal industry and from states that get a large portion of their energy from coal power inevitably will lead to legal challenges, said Richard Faulk, an environmental lawyer at Hollingsworth LLP, a Washington, D.C., law firm.
