The EPA proposed strict limits on greenhouse-gas emissions from new power plants despite warnings from utilities and others that such a step would lead to the demise of coal-fired electricity generation.
The agency outlined a standard that analysts said would effectively ban new coal-fired stations unless they use carbon-capture technology, which hasn't yet been proven cost-effective.
The EPA said the rule wouldn't apply to existing power plants, including when they make modifications to comply with other air-pollution rules, addressing a major concern of the power industry.
