Environmental Protection Agency (EPA) Administrator Lee Zeldin on Thursday will eliminate the "2009 Obama EPA Endangerment Finding," which set in motion most federal greenhouse gas emissions standards for vehicles, saving Americans billions. The 2009 development was an EPA finding that carbon dioxide, methane, nitrous oxide and three other greenhouse gases "endanger the public health and welfare of current and future generations" under the Clean Air Act " leading to a slew of new restrictions and regulations. An ensuing Supreme Court ruling in Massachusetts v. EPA found greenhouse gases qualify as air pollutants and that if the EPA determines they endanger public health or welfare it can regulate them.
