Generation Z and climate mitigation initiatives: Understanding intention to join national tree-planting projects

Climate change is one of the most significant challenges facing humanity, with the potential to impact various aspects of life. To mitigate and adapt to climate change, programs are being developed and implemented at local, national, and international levels. National tree-planting initiatives are one such effort being undertaken by various countries, aiming to engage the public in planting trees to mitigate the effects of climate change. However, the success of these programs depends on the participation of diverse groups, particularly students, who are the future leaders of our planet. Identifying the factors that determine their intention to participate in these initiatives is crucial. This study aims to fill the research gap incorporating two additional constructs in an extended theory of planned behavior including climate change awareness and perceived climate change risk. The study examined the intention of 521 Generation Z students in Iran to participate in national tree-planting programs. The structural equation modeling was applied to data analysis. The results indicated that the extended model could explain 73 % of the students' intention to participate in national tree-planting initiatives. The findings revealed that perceived behavioral control, attitude, climate change awareness, perceived risk, and subjective norms are the most significant factors in determining students' intentions. The study concluded that empowering students regarding tree planting, raising awareness about climate change and its risks, and enhancing their attitudes are essential strategies for increasing their participation in national tree-planting programs aimed at mitigating the effects of climate change.
