"Urging the justices to hear the case, one of the challengers, the North American Coal Corporation, acknowledged that the issue of climate change and how to address it has “enormous importance,” but the company stressed that “[t]hose debates will not be resolved anytime soon.” What the court should resolve, it continued, “as soon as possible is who has the authority to decide those issues on an industry-wide scale — Congress or the EPA.” Unless the justices weigh in, the company warned, “these crucial decisions will be made by unelected agency officials without statutory authority, as opposed to our elected legislators.”"
