UNDERSTANDING CLIMATE CHANGE BEHAVIORS USING A MODIFIED THEORY OF PLANNED BEHAVIOR

Climate change impacts are uncertain, and greenhouse gas emissions are a structural part of individuals’ everyday lives, making behaviors to mitigate climate change a particular challenge in promoting human well-being and environmental protection. Behaviors that encourage sensible policy development around climate change, such as voting, are particularly important in encouraging societal-level response to climate change. However, a large attitude-behavior gap persists in individuals’ pro-environmental behaviors. Integrating environmental behavioral theories may produce a model that guides researchers and educators in better understanding environmental attitudes and behaviors. A survey was developed using the Theory of Planned Behavior and Values-Belief-Norms Theory to measure climate change behaviors and their determinants, and was distributed to non-science major undergraduates (n=132). These individuals are likely to become politically active, and unlikely to engage in climate science through their education, thus representing an important group to target in studying climate change behaviors. Students also responded to questions measuring their understanding of the scientific processes of climate change. Structural equation modeling was used to elucidate important determinants of pro-environmental behaviors. Personal norms and subjective norms are particularly strong indicators of pro-environmental behavioral intentions. Knowledge of climate change processes was not related to students’ intentions to engage in pro-environmental behaviors. The goal of this work is to provide a theoretical framework for developing a workshop intervention for individuals to engage in behaviors that align with their attitudes and values in relation to climate change.
