The ongoing political, social, and industry focus on climate change has led to the creation of international agreements, national legislation, and regulatory programs to reduce Ghg emissions. In December 2009, the Environmental Protection Agency deemed Co2 methane and other GHG emissions as a threat to public health and the environment. The Environmental Protection Agency issued regulations in 2012 and 2016, both of which were rescinded by the Trump Administration and a 2020 methane policy rule. The White House Office of Domestic Climate Policy released a U S Methane Action Plan in November 2021.
