As environmental consciousness continues to shape consumer behavior, the hospitality industry is increasingly integrating sustainable practices into its operations. This study investigates the impact of green hospitality initiatives-such as energy efficiency, waste reduction, eco-friendly amenities, and sustainable sourcing-on guest satisfaction and loyalty. Through a mixed-methods approach combining guest surveys and hotel manager interviews, the research identifies a strong positive correlation between the implementation of visible, authentic green practices and customer satisfaction. Furthermore, it reveals that satisfied guests are more likely to exhibit loyalty behaviors, including repeat visits and positive word-of-mouth referrals. The findings underscore the strategic value of sustainability in hospitality, not only as a means of environmental stewardship but also as a competitive differentiator in a crowded market. Practical recommendations are provided to help hotels align sustainability goals with customer expectations and business performance.
