Three lawsuits have been filed seeking to block the Trump administration’s efforts to sell oil leases in the Arctic National Wildlife Refuge. The National Audubon Society, Natural Resources Defense Council, Friends of the Earth, and Center for Biological Diversity have signed off on a lawsuit sighting insufficient concern over increased greenhouse gas emissions and melting permafrost, poor air quality, and negative impacts to the region’s wildlife. The lawsuit alleges violations of the National Environmental Protection Act, the National Wildlife Refuge System Administration Act, and the Endangered Species Act. A second lawsuit, filed by the Gwich’in Steering Committee also sites violations of the Alaska Native Claims Settlement Act, and includes plaintiffs in Canada’s Yukon chapter of Canadian Parks and Wilderness Society. Most recently, a third lawsuit was put forth by fifteen states including California, Connecticut, Delaware, Illinois, Maine, Maryland, Massachusetts, Michigan, Minnesota, New Jersey, New York, Oregon, Rhode Island, Vermont and Washington. Concerns addressed in this lawsuit include habitat damage and greenhouse gas emissions, as well as impacts to waterfowl hunting and a lucrative birdwatching industry for birds that breed on the Arctic plain and overwinter in the lower 48 states.
