A New Jersey court recently ruled that Gov. Chris Christie lacked the legal justification for pulling his state out of the Regional Greenhouse Gas Initiative in 2011. What could the court's decision mean for the state's future participation in RGGI? And what role could RGGI play in U.S. EPA's pending existing source rule for power plants? During today's OnPoint, Collin O'Mara, secretary of Delaware's Department of Natural Resources and Environmental Control and immediate past chairman of RGGI, discusses the role state flexibility will likely play in EPA's final rule for existing sources. He also talks about RGGI's upcoming June auction.
