Pro-environmental behaviors are behaviors adopted by individuals that aim to protect thenatural environment and reduce damage to the environment. In research in the field of psychology, thetheoretical mechanisms explaining this behavior have focused on three major theoretical frameworks suchas Theory of Planned Behavior, Environmentally Responsible Behavior, and Norm-Activation Theory.Factors affecting pro-environmental behavior can be attributed to two main dimensions: cognitive andemotional-affective. Specifically, the cognitive dimension mainly involves the individual's values, socialcognition, and environmental efficacy, while the affective dimension covers the influence of negative andpositive emotions, self-transcendence emotions, and natural empathy on pro-environmental behavior. Inthe future, we can further analyze the intrinsic mechanisms and influencing factors of pro-environmentalbehaviors, and actively explore effective ways and application scenarios to enhance pro-environmentalbehaviors.
