Research hotspots, future trends and influencing factors of tourism carbon footprint: a bibliometric analysis

To comprehensively analyze the current research status, hot trends, and influencing factors of tourism carbon footprint, this paper conducts a bibliometric analysis. We find that (1) tourism carbon footprint is the topic with the highest attention in the field of tourism footprint research; (2) economic effects, tourism carbon footprint accounting methods, and the consciousness drive of each subject in the tourism industry are still important research directions; (3) tourism activity items such as accommodation and transportation are the main influencing factors while the behavioral preferences and characteristics of tourists, government and tourism operators become important directions for future empirical research.
