Extending the theory of planned behavior model to explain people's energy savings and carbon reduction behavioral intentions to mitigate climate change in Taiwan-moral obligation matters

This study aims to extend the theory of planned behavior (TPB) model to explain people's intentions to engage in energy savings and carbon reduction behaviors that can help mitigate climate change in Taiwan. People's moral obligation to perform such pro-environmental behaviors is further considered in the TPB model. The results indicate that the extended TPB model including moral obligation can increase the explanatory power of the original one. In addition to one's attitudes and subjective norm, one's moral obligation to reduce impact on global warming and climate change plays a significant role in predicting one's intentions to engage in energy savings and carbon reduction behaviors to mitigate climate change problems.
