"Environmentalists are suing U.S. EPA over a rule that aims to regulate greenhouse gases from only the largest industrial sources, arguing that the agency exempts too many big polluters.

But while industry groups argue that EPA climate rules will hurt businesses, CBD says the agency is not going far enough."
