Promoting environmentally responsible behavior is important in preventing and reducing the environmental problem. This work focused on particular environmentally responsible behavior (avoiding and reducing littering). The present study extended the Theory of Planned Behavior (environmental knowledge, biospheric value, and positive emotional experience) to identify the factors influencing intended environmentally responsible behavior of tourists visiting nature based destinations in the context of Indonesia. Based on the data collected from 204 respondents through questionnaires survey using purposive sampling approach. The structural equation analysis shows that biospheric value, environmental knowledge, and positive emotional experience have a positive influence on attitude toward behavior. Besides, the result demonstrated that attitude, subjective norm, and perceived behavior control have a significant positive influence on environmentally responsible behavior intention. The findings emphasized that positive emotional experiences have a strongest influence on attitude and perceived behavior control have a strong influence on environmentally responsible behavior. This work contributes to the sustainable development goals and environmentally responsible behavior in tourism behavior literature. Although, some limitations were acknowledged in this work, practical implication and future agenda for research are provided.
