Western Energy Leases

Trinidad Drilling rigs are seen off of Way Highway 59 outside of Douglas, Wyo., in 2013. A federal judge has blocked oil and gas drilling on almost 500 square miles in Wyoming, saying the government must consider cumulative climate change impacts of leasing public lands across the U.S. for energy development. The order marks the latest in a string of court rulings over the past decade faulting the government's consideration of emissions when issuing energy leases.
