To date, climate change is a major issue debated globally. Climate change has impacted human life and the environment. Mitigating the effects of climate change requires individuals with friendly behaviour towards climate change. This study aimed to examine the relationship of preservice teachers' friendly behaviour towards climate change through the level of knowledge, awareness, risk perception, and attitude of preservice teachers. This study involved 256 preservice teachers at four universities in the state of Selangor. A questionnaire with a five-point Likert scale was used for the purpose of data collection. The data obtained were analysed using SPSS 23.0 software. The results of the study indicated that there was a significant but moderate relationship between awareness and risk perception with the climate change-friendly behaviour of preservice teachers. The study also found that there was a significantly weak relationship between knowledge and attitudes towards preservice teachers’ climate change-friendly behaviours. Preservice teachers have the knowledge and awareness of climate change that has a negative impact on socio-economy and disrupts the ecosystem of the human life. However, this awareness does not influence the preservice teachers to demonstrate attitudes and behaviours towards reducing the effects of climate change.
