On the basis of the protection motivation theory (PMT) research model, this study employed perceived moral obligation as a determinant to improve predictions of people’s intention to engage in energy savings and carbon reduction behavior aimed at mitigating the threat of environmental climate change through their protection motivation. The sample comprised 930 participants who completed self-reported questionnaire surveys in Taiwan. The empirical results of structural equation modeling indicated that the extended PMT model was more explanatorily powerful than the original model. The results not only confirmed that people’s perceived moral obligation plays a crucial antecedent role in predicting their intention to engage in energy savings and carbon reduction behavior but also verified the mediation effects of protection motivation in the extended PMT model.
