(FOX NEWS) The Obama administration took aim at the coal industry on Monday by mandating a 30 percent cut in carbon emissions at fossil fuel-burning power plants by 2030 — despite claims the regulation will cost nearly a quarter-million jobs a year and force plants across the country to close.

The controversial regulation is one of the most sweeping efforts to tackle global warming by this or any other administration.

The 645-page rule, expected to be final next year, is a centerpiece of President Obama’s climate change agenda, and a step that the administration hopes will get other countries to act when negotiations on a new international treaty resume next year.
