Abstract
This study will explore sustainable leadership in the hotel industry of Nigeria through a multi-level competency model approach. Financial restrictions, knowledge gaps, and different managerial competencies make it difficult for Nigerian hotels to incorporate sustainable practices as sustainability becomes a major concern of leadership. This study intends to pinpoint important sustainable leadership competencies at the top, middle, and lower management levels, thereby addressing adoption challenges and offering a structure for successful application. This qualitative study will examine 35 hospitality industry participants. Purposive sampling will ensure sector role diversity. Semi-structured interviews will allow for thorough discussions while maintaining flexibility. The interviews will be recorded and transcribed for research. Thematic analysis will identify, assess, and summarise data themes to provide a complete understanding. This study will provide insightful analysis for legislators, hotel managers, and stakeholders in improving sustainable leadership practices utilizing a multi-level competency model. The results will help to close the knowledge-application gap in competencies challenges faced by the tier of management in hospitality industries.
