Abstract: As the continuous growth of aviation carbon emissions, guiding passengers to participate in aviation carbon offsetting has become an important pathway for the aviation industry to achieve net-zero emissions. Based on the theory of planned behavior, a theoretical model of passengers’ willingness to participate in aviation carbon offsetting incorporating fairness perception was constructed. Then, through a questionnaire survey of 502 air passengers and combining partial least squares structural equation model (PLS-SEM) and necessary condition analysis (NCA) method, the formation mechanism and its necessary conditions of carbon offset participation willingness were explored. The research results show that: ①except for the insignificant effects of benefit visibility on fairness perception and information transparency on participation willingness, all other hypotheses are supported; ②fairness perception plays a mediating role among certification credibility, information transparency, environmental efficacy, price acceptance, and participation willingness; ③ information transparency is a necessary condition for the medium effect of fairness perception. The research conclusions contribute to passengers’ deeper understanding of the factors influencing their willingness to participate in carbon offsetting and offer theoretical reference and practical basis for the design of carbon offset projects and the development of participation promotion strategies.
