Marine plastic pollution (MPP) is increasing in recent times because of the high usage of plastic products. Green consumption behaviour (GCB) gaining attention as effective approach to achieving sustainable source reduction of plastic pollution, which negatively affects both human pollution and marine biodiversity and ecosystem. Although, Higher Education (HE) students are key stakeholders in addressing environmental issues, including MPP, there is limited empirical research in Ghana on factors influencing HE students’ GCB. This study, in an endeavour to bridge the gap, used the revised theory of planned behaviour (TPB) framework to investigate the factors influencing higher-education students’ green consumption behaviour in the Ghanaian context. Specifically, the purpose of the study is to examine the interplay of consumer novelty seeking (CNS), environmental concern (EC), perceived behavioural control and social influence on green consumption behaviour among higher-education students in Ghana. The study also explored the moderating role of gender in the relationship between CNS and green consumption behaviour.

This study used quantitative approach to obtain data from a sample of 233 students at the University of Cape Coast and used the partial least squares structural equation modelling approach for the data analysis.

The findings provide valuable insights, highlighting the important role of CNS and ECs in driving higher education students’ green consumption behaviour in Ghana. This study also found a revealing role for gender as a moderator in the relationship between CNS and green consumption behaviour, with females exhibiting a more pronounced response to CNS in influencing green consumption behaviour. On the contrary, the authors found a non-significant impact of perceived behavioural control and social influence.

Although this study presents results that provide valuable insights for policy and practical implications, it has some limitations worth mentioning for future research directions. Firstly, the participants sampled for this study comprised only higher education students from the University of Cape Coast in Ghana, which may limit the applicability of the findings to other student populations at various universities in Ghana and beyond. Moreover, the exclusion of non-students who are considered as “Generation Z” (i.e. born within 1995–2010) may narrow the scope of generalisability in the context of young consumers’ green consumption behaviour in Ghana. To enhance the generalisability of future studies, it is recommended that the scope of this study be extended. Furthermore, it should be noted that this study primarily measured higher education students’ green consumption behaviour based on self-reported data. Therefore, future research could adopt alternative approaches, such as non-self-reported measures or experimental data so to reduce the complexities and the gap that may exist between attitudes and behaviour.

These results provide valuable insights for policymakers, educators and environmental advocates to develop targeted initiatives that resonate with Ghanaian higher education students to foster green consumption practices and contribute to global efforts against marine plastic pollution.

The novelty of this study lies in the decision to propose a TPB model by including variables like CNS and EC that are believed to positively shape attitudes towards green consumption behaviour. The rationale for examining these variables is grounded in the belief that they are appropriate factors that may predict students’ green consumer behaviour, which may serve as a potential solution to marine plastic pollution.

Training cannot be effective if trainers are not pedagogically competent. However, the influence of trainers’ pedagogical competencies on employees’ knowledge and skill acquisition during training is not given the needed attention in the training literature. This study aims to examine the influence of trainers’ pedagogical competencies such as delivery, trainees’ involvement, use of visual aids and body language on trainees’ assimilation of training content.

The data are analyzed from 425 respondents in an online survey. This study uses structural equation modeling in testing the hypotheses following validity and reliability tests.

This study finds that trainers’ pedagogical competencies such as trainee involvement and body language have a significant influence on trainees’ assimilation of training content, but others such as the trainers’ delivery and use of visual aids do not have a significant influence on assimilation of training content.

Professionals responsible for training should endeavor to use trainers who have been proven to be pedagogically competent, especially involving trainees during training and use of body language and not just experts in the topics/areas they provide training. Trainers themselves should on their part do well to acquire pedagogical skills in addition to the content knowledge they possess to enhance their training effectiveness particularly, trainees’ assimilation of training content.

As a phenomenon rarely given attention, this study urges learning and development researchers and practitioners as well as human resource management professionals to give attention to the pedagogical competencies of trainers during training and trainees’ learning.
