The widespread use of single-use plastics (SUP) is a growing environmental issue, particularly in Thailand, where plastic waste poses significant challenges. A recent study by Dr Oluseye Oludoye, focusing on Thai university students, explores the factors influencing their efforts to reduce plastic consumption, offering valuable insights for promoting sustainability. Using the Theory of Planned Behaviour, the research examined how attitudes, perceived control, and social influences affect students’ intentions at different stages of behaviour change.

The findings show that while positive attitudes towards reducing SUP are important, they only encourage action among students already contemplating change. In contrast, students’ belief in their ability to make a difference—perceived behavioural control—proved crucial across all decision-making stages. Social influences also played a key role in shaping initial attitudes, highlighting how peer dynamics can motivate change.

These insights are essential for educators and policymakers aiming to foster sustainable behaviours. Campaigns tailored to different stages of behaviour change can be more effective, and leveraging social influence through student-led initiatives could further encourage action. The study also suggests that reducing SUP might inspire students to adopt other sustainable practices. Overall, this research enhances our understanding of engaging young adults in environmental efforts and paves the way for a more sustainable future.
