Exploring consumers' social media engagement in addressing plastic pollution

PurposePlastic pollution is a major issue that plagues modern society. Scholars are interested in comprehending consumers' behavioural actions to address plastic pollution. This study aims to delve into the determinants of consumers' engagement with social media as a medium to address plastic pollution.Design/methodology/approachA conceptual model is developed that extends the behavioural reasoning theory (BRT). Using a quantitative approach, 476 responses underwent structural equation modelling analysis.FindingsResults indicate that "reasons for" positively correlate with attitude and intention towards socially responsible engagement. Contrarily, "Reasons against" demonstrated a positive association with socially responsible engagement intention. Attitudes favouring socially responsible engagement correlate positively with the underlying intention. The moderation analysis underscores the positive relation of social return on social media with consumers' attitude and their "reasons for" leaning towards socially responsible engagement intention. Notably, a positive connection was established between socially responsible engagement intention and the trifecta of consumption, contribution and content creation behaviours.Originality/valueBy enhancing the BRT, this research sheds light on novel perspectives regarding consumers' engagement on social media platforms. Distinctively, it is among the handful of studies probing the influence of behavioural intention across diverse behavioural outcomes. The insights gained from this study, grounded in empirical evidence from an emerging market, are poised to guide policymakers, governmental agencies and industry practitioners in formulating effective strategies to combat plastic pollution. Additionally, the study can assist in achieving the UN sustainable development goals (SDGs), specifically SGD 12, SGD 13, SDG 14 and SGD 17.
