The study examined the relationship between environmental attitude, environmental subjective norm, environmental perceived behavioural control, and school headteachers' environmental responsive behaviour. The population of the study consists of primary school headteachers in the northern region of Malaysia who are attached to the Ministry of Education (MoE), Malaysia. An online survey was used to collect the data of the study from 167 sampled respondents. While Theory of planned behaviour underpinned the study, the researcher employed explanatory, descriptive, and hypothesis testing quantitative strategies to explain the relationship. Smart PLS 3.0 and SPSS 21 were equally used to analyse the data. The result of the data analysis revealed that environmental attitude, environmental subjective norm, and environmental perceived behavioural control significantly influence school headteachers' environmental responsive behaviour.
