Promoting pro-environmental travel modes is an important strategy for sustainable transportation. Previous studies have shown a positive relationship between environmental awareness and environmental-friendly travel modes, but very few studies have considered pro-environmental behaviour and choice of travel mode, particularly in the context of non-Western countries. This study examines the impact of pro-environmental behaviour on the choice of commuting mode in Tokyo, Beijing, Shanghai and Singapore using original survey data. We use the Multiple Indicator Multiple Cause model to construct latent variables of environmentally friendly behaviours. The multinomial logistic regression results indicate that (1) pro-environmental activities and commuting mode choice are unrelated in Tokyo and Singapore, (2) recycling and energy-savings activities are positively related to commuting by bicycle/on foot in Beijing, and (3) participants in organised pro-environmental activities are less likely to use pro-environmental commuting modes in Beijing and Shanghai. The results provide supporting evidence of the habit discontinuity hypothesis and suggest a possible substitution effect between environmentally friendly travel mode choice and other environmental activities.
