This study focuses at the strategies implemented by Bali Marriott Hotels' Front Office Department to encourage environmentally conscious actions among its employees. The research used a mixed-methods methodology over a six-month period in 2024, focusing on three luxury properties: The St. Regis Bali Resort, The Westin Resort Nusa Dua Bali, and The Laguna, A Luxury Collection Resort & Spa. The results show that front office staff members' environmental awareness as well as involvement were greatly increased by a variety of strategies that included comprehensive training, operational integration of green practices, employee recognition programs, cross-departmental collaboration, guest engagement, and innovative use of technology. According to the study, luxurious hotels may successfully implement sustainability programs without compromising the guest experience.
