Climate change in the 21st century has become an increasingly pressing issue, yet little has been done to effectively mitigate and combat it. The polarized nature of American politics today has resulted in a stark difference in opinion between Republicans and Democrats on climate change with nearly all Democratic members of Congress voting in support of climate change mitigation bills. Yet not every Republican votes the same way on climate change, making the variance of such voting behaviors worthy of research. In this study, a climate scoring tool is created and applied to House Republicans of the 116th Congress. The resulting scores for each member are then placed in context with various political and environmental variables, to analyze influence on such voting behavior. The voting behavior on climate change legislation of House Republicans in the 116th Congress is largely driven by ideology, with increasing levels of conservatism strongly correlating with lower support for climate change legislation. Beyond ideology, the climate scoring tool highlights compounding effects of coastal vulnerability and age on Republican voting behavior.
