Introduction: As sustainability becomes a major global concern, the sports sector also plays a significant role in environmental degradation. This makes it a crucial area of focus for research aimed at achieving sustainability goals. Objective: This study examines the influence of green human resource management practices—specifically green hiring, green training, performance management, and employee involvement—on the sustainable performance of enterprises in India’s sports service sector. Methodology: A stratified random sampling technique was used to ensure representation across various sports service industries. A total of 500 respondents from the Delhi National Capital Region were surveyed. Descriptive statistics, one-way analysis of variance, and regression analysis were conducted to test the proposed hypotheses. The theoretical framework was based on the ability, motivation, and opportunity model. Results: The results showed that green hiring, green training, and performance management practices had a statistically significant and positive influence on sustainable performance. However, employee involvement did not demonstrate a significant relationship with sustainable outcomes. Discussion: The variation in the use of green human resource management practices among organizations suggests the need for more focused and customized strategies to improve environmental performance.
