This research aimed to investigate the impacting psychological factors for Vietnamese’s intention to stop littering. A quantitative method using self-reported online questionnaire was adopted to collect data from Vietnamese residents and Partial Least Squares Structural Equation Modelling (PLS-SEM) method was employed to examine the proposed relationships. The results indicate that higher connectedness to nature and lower perceived behavioral control are associated with higher intention to stop littering in Vietnam. Limitations of current study and future research directions are outlined.
