Camping tourism is a relatively new form of travel and leisure, it has left many traces of consumption in the natural environment that cannot be restored. In order to assist consumers in camping in a polite, environmentally conscious, and traceless manner, this study begins with consumption motivation, consider leisure involvement and place attachment as dual intermediary variables, and investigates the mechanisms that influence the pro-environmental behaviour of leisure and camping tourists. The research findings are derived from the motivation-oriented behavior mechanism. (1) Consumption motivation has a significant positive impact on pro-environmental behavior. (2) Leisure involvement plays a mediating role between consumption motivation and pro-environmental behavior. (3) Place attachment plays a mediating role between consumption motivation and pro-environmental behavior. (4) Leisure involvement has a significantly positive impact on place attachment.
