Hotel companies strive for ESG activities based on various environment, society, and governance forms to ensure sustainability. This study examined hotel consumers' perceptions and trends on hotel ESG-related keywords extracted from online social media. The results are as follows. First, keywords such as management, Lotte Hotel, eco-friendly, society, environment, company, sustainability, hosting, vision, practice, governance, continuity, strengthening, and organization showed a high frequency of appearance. Second, through the CONCOR analysis, a total of six clusters were identified. The names of the clusters were confirmed as ESG-related practice and participation, value creation, vision and change, dedicated organization, guest room introduction, and eco-friendly practice. Based on these findings, we would like to provide practical implications that can be applied to hotel companies and academic implications that can be used in hotel academia.
