This study aimed to examine the role of environmental commitment, environmental consciousness, green lifestyle, and green self-efficacy in influencing pro-environmental behaviour. Data were obtained through a survey of 72 students at one of the training centers in Malaysia. The hypothesized relationships were tested using partial least squares (PLS) methodology. Results showed that environmental commitment, environmental consciousness, green lifestyle, and green self-efficacy positively influenced pro-environmental behaviour, thereby providing new insights to existing literature on environmental sustainability. The results may be used by educational institutions, the government, and private agencies to strengthen students’ knowledge, attitude, and behaviour that support environment-based education. The scope of the study was limited to students at a training center, so the results may not be generalizable to different settings. Another limitation was that the study used limited contextual elements. The novelty of this study is that it examined the role of environmental commitment, environmental consciousness, green lifestyle, and green self-efficacy as determinants of pro-environmental behaviour among students in an educational setting in Malaysia.
