| Summary | CO2 and greenhouse gas emissions are rising year by year. While the transportation industry accounts for 20% of the total. Among them, the aviation industry accounts for 12%. In order to solve this problem and achieve the goal of net-zero carbon emissions, international organizations and airlines have proposed carbon offset schemes, which passengers can achieve carbon neutral for the flight through voluntary carbon offsets. However, most of the research focuses on the willingness to pay for carbon offset, but does not discuss other services as exchange items. Therefore, this study designed preference questionnaire to analyze passengers' preference and estimated Multinomial and Latent Class logit model to analyze the heterogeneity of passengers and calculate willingness to pay. In addition, we estimated Contingent valuation method to compare the price by three model’s result. The results of multinomial logit model show that there are significant differences in travelers' attention to each attribute. In latent class logit model, one of the two groups comprises passengers with income and whether they are environmentally friendly. For passengers in class1, variables of carbon offset are significant differences, however, others are sensitive to price. The results of tri-bounded dichotomous choice model are when the number of travelers increases, the willingness to pay of passengers will decrease. As passengers with business trips or aged 25-64 or with a master’s degree, and when the income increases by 1%, the willingness to pay for carbon offset will increase. Finally, comparing the willingness to pay for carbon offset estimated by the three models with |
