The role of voluntary green behavior and green performance in promoting sustainability in the hospitality industry

This study aims to explore how green training, green commitment, and green information management affect green performance in 5-star hotels in Medan City, focusing specifically on voluntary green behavior. The study's participants included 331 employees from seven 5-star hotels in Medan City: JW Marriott Hotel, Aryaduta Hotel, Grand Mercure, Cambridge Hotel, Grand City Hall Medan, Hotel Danau Toba International, and Adimulia Hotel. Each of these hotels has been in operation for more than five years. Data was collected through a questionnaire and analyzed using structural equation modeling (SEM). The findings confirm that green training, green commitment, and green knowledge management play important roles in promoting sustainable practices in the hotel industry. Investing in employee training to build knowledge and skills, showing strong management commitment to sustainability, and implementing effective knowledge management are key to creating a work environment that supports sustainability and environmental responsibility. The managerial implications suggest that hotels should focus on developing policies and programs that encourage sustainable practices. This includes improving education and training, strengthening organizational commitment, and adopting effective knowledge management practices. By doing so, hotels can enhance their sustainability performance and strengthen their reputation and competitiveness in an increasingly eco-conscious market.
