The hospitality industry is one of the most significant drivers of economic development, while at the same time being closely associated with environmental pollution. This research evaluates the current status and success of eco-friendly activities in hotels in the Delhi NCR area. In the following quantitative survey, 270 managers, employees, and sustainability officers from different hotels and resorts completed a structured questionnaire. The research focuses on the relationship between waste management, energy efficiency, water conservation, green procurement and the overall sustainability performance of the hotels. Multiple regression analysis is used to investigate the extent to which these sustainability initiatives affect hotel performance and their significance. It also focuses on the difference in sustainability adoption by hotels, including luxury, mid-range, and budget rooms. The preliminary study further concludes that energy efficiency and green procurement have a significant influence on sustainability performance, while operational issues constrain waste management activities. This study is valuable for the development of knowledge about sustainability in a developing country context by offering insights into the current state of sustainability practices in the Indian hotel industry. Finally, the study provides insights for hotel managers, policymakers, and regulatory bodies to enhance their environmental measures in the hospitality industry. This is a clear implication that policy support, technology improvement, and the adoption of appropriate employee training programs should be encouraged to improve sustainability in the sector..
