Global environmental challenges
If you took all the cows in the United States and figured out how much greenhouse gas they emit, would you be able to sue all the farmers who own them?
That interesting legal question came from Justice Antonin Scalia during Supreme Court oral arguments about whether an environmental case against five big U.S. power companies can go forward.
At issue is whether six states can sue the country’s biggest coal-fired electric utilities to make them cut down on the climate-warming carbon dioxide they emit. One lower court said they couldn’t, an appeals court said they could and now the high court will consider where the case will go next. A ruling should come by the end of June.
For now, though, the question was cows.
Attorney Barbara Underwood argued that the five power companies were the largest emitters of carbon dioxide in the United States, making up 10 percent of U.S. emissions. No other company comes close, she said.
