Hotel support the growth of the tourism industry. At the same time, the tourism industry contributes to the country's gross domestic product, particularly Indonesia. Besides, the hotel operation is obliged to play a role in preserving the environment sustainability, called green hotel. The implementation of green hotels requires the attention of top management to involve all the company's functions. This study examines the impact of the top management attentiveness on the green performance through implementation of green purchasing and supplier relationships. The research has surveyed 59 3-star hotels that have implemented green purchasing practices. Data collection used a questionnaire and then analyzed with descriptive statistics, while hypothesis testing used the PLS technique. The results indicate that top management attentiveness improved the implementation of green purchasing and supplier collaboration. Supplier collaboration improved the green purchasing. Top management attentiveness, green purchasing, and supplier collaboration can increase green performance since the operations become more efficient while minimizing waste. This research paves the way for hotel management to be more concerned about adopting the green hotel approach in improving firm performance. This study also contributes to the on-going research in supply chain management.
