The ongoing political, social, and industry focus on climate change has led to the creation of international agreements and regulatory programs to decrease Ghg emissions. In December 2009, the Environmental Protection Agency determined that Co2 methane and other GHG emissions pose 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 The Environmental Protection Agency issued regulations in 2012 and 2016, both of which were rescinded by the Trump Administration and a 2020 methane policy rule.
