A coalition of health and environmental groups sued the Environmental Protection Agency on Wednesday, challenging its determination last week that revoked a scientific finding that has been the central basis for U.S. action to regulate greenhouse gas emissions and fight climate change.
A rule finalized by the EPA on Thursday rescinds a 2009 government declaration known as the endangerment finding that determined that carbon dioxide and other greenhouse gases threaten public health and welfare. The Obama-era finding is the legal underpinning of nearly all climate regulations under the Clean Air Act for motor vehicles, power plants and other pollution sources that are heating the planet.
