This study aimed to explore effective corporate social responsibility (CSR) communication strategies to increase hotel guests’ engagement in climate change initiatives. Utilizing regulatory fit theory and construal level theory, three scenario-based experimental designs were devised. These designs empirically analyzed the responses of 1500 hotel guests to 12 different types of CSR communication messages. Framed along goal framing (either gain or loss) and temporal/spatial/social distance (either far or close), these messages allowed guests to articulate their attitudes and behaviors concerning climate change engagement. All three experiments revealed that CSR communication became more persuasive with regulatory fit, leading to increased intentions for green word-of-mouth (green WOM) and a willingness to pay a green premium (green WTPP). To further validate the findings, the study also investigated the moderating effect of temporal/spatial/social distance on message framing. We found that temporal distance amplified the congruence between goal framing and regulatory focus, resulting in heightened green WOM intentions. Social distance also increased this alignment, resulting in heightened green WOM intentions and green WTPP. This study contributes to the literature on hotel guest climate (change) engagement by examining the concept through CSR communication strategies. It offers a valuable perspective on the nexus of guest engagement, CSR, and sustainability, contributing uniquely to theory and practice in these interconnected fields.
