Abstract
This study examined how air passengers in Japan perceive the environmental impacts of air travel and how it is related to their offsetting behaviors and subjective well-being. The analysis of questionnaire data from 1,624 customer loyalty program members of a domestic airline company showed that the perceived environmental impacts of air travel were positively associated with pro-environmental behaviors in daily life and traveling domains, pro-social behaviors, and willingness to pay for carbon offsetting. Additionally, pro-social behaviors and willingness to pay for carbon offsetting were positively related to subjective well-being. The study also explored potential direct and alternative approaches to achieve sustainability in air transport.
