As of March 2014, 166 bills focusing specifically on climate change had been introduced in the 113th Congress (2013-2014). Many more bills touch on energy, environment, transportation, agriculture and other areas that could have an impact on or be affected by climate change. The list below, however, contains for the most part only those bills whose authors explicitly reference climate change or related terms, such as greenhouse gases (GHG) or carbon dioxide. (For brevity, all legislative proposals, including resolutions and amendments, are referred to here as "bills.") The list includes 104 bills that are intended to advance climate action, as well as 62 bills that would hinder climate action, 34 of which would curb EPA’s ability to regulate greenhouse gas emissions from power plants.
Though they do not specifically mention climate change, this list also includes those bills dealing with the impact of Hurricane Sandy which have been signed into law, as well as the Shaheen-Portman and McKinley-Welch energy efficiency bills, which are considered the best prospects for enactment among energy bills in this Congress. Climate action advocates have supported both issues, though in a sign of the times, the authors have avoided mentioning climate change in the bills themselves.
The list also includes Public Law 113-89, which reverses many of the provisions of the Flood Insurance Reform Act of 2012, and was enacted into law despite being opposed by climate action and taxpayer advocates.
The bills, resolutions, and amendments of the 113th Congress dealing with climate change are divided into the following categories:
