Environmental laws and regulations

FILE - In this April 20, 2013 file photo, male greater sage grouse perform mating rituals for a female grouse, not pictured, on a lake outside Walden, Colo. Interior Secretary Ryan Zinke is ordering a review of federal efforts to conserve the imperiled sage grouse to ensure that officials in 11 Western states where the bird lives are fully consulted. Zinke says that while the federal government has a responsibility under the Endangered Species Act to protect the ground-dwelling bird, “we also have a responsibility to be a good neighbor and a good partner.” He says a directive that could “destroy local economies” or impose onerous regulations on public lands “is no way to be a good neighbor.’’ (AP Photo/David Zalubowski, File)

The Justice Department lawsuit alleges that nearly 104,000 Ram pickups and Jeep Grand Cherokees from the 2014 to 2016 model years have software that allows them to emit lower amounts of pollutants during lab tests by the Environmental Protection Agency than during normal driving conditions.
