"In the 113th Congress, Members have introduced multiple bills that include provisions that would directly or indirectly address climate change-related issues. In some cases, it is difficult to distinguish between direct and indirect climate change bills, because a specific bill or action may seek to achieve multiple objectives. The bills listed in this report include provisions that 'directly' address climate change, as opposed to those that primarily address other issues (e.g., energy efficiency) but could have ancillary impacts on climate."
