The objective of this study was to explore how different types of rewards affect customers’ inclinations to engage in environmental activities promoted through restaurant social media platforms. In addition, we investigated the potential moderating role of customer level of participation within the social media community. A total of 202 valid responses obtained by distributing a self-administered survey among restaurant patrons were subjected to hierarchical regression analysis to examine relationships between variables. The findings underscored the significant influence of economic and social rewards on shaping customer intent to participate in environmental initiatives promoted within restaurant social media communities. Furthermore, the study revealed that the extent of customer participation within the social media community moderated the relationship between rewards and their likelihood to partake in environmentally conscious behaviors. These results have meaningful implications for restaurant managers seeking to promote environmental initiatives effectively through social media platforms and within their establishments.
