Background: Growing environmental challenges necessitate the implementation of sustainable practices across various sectors, including sports club management. The aim of this study was to investigate environmental management practices in martial arts clubs in Poznan, Poland, with a particular focus on energy and water conservation, waste management, and the promotion of sustainable mobility. Materials and Methods: A qualitative study was conducted with a group of fourteen martial arts clubs operating in Poznan. A semi-structured interview method was employed with club owners and managers, asking about their approaches to reducing energy and water consumption, waste sorting, waste reduction, and promoting sustainable transportation. Data analysis involved thematic analysis, where the practices adopted by individual clubs were compared and qualitatively assessed based on recurring themes. Results: The results indicate significant variability in approaches among the surveyed clubs. Only one club implements comprehensive solutions for energy and water conservation and four take moderate actions, while nine do not pay much attention to these issues. Similarly, only some clubs actively engage in waste sorting and waste reduction efforts, while others do not see the need for such actions. In terms of promoting sustainable transportation, some clubs encourage the use of bicycles and public transport, but the majority do not take any action in this regard. Conclusion: The study reveals that most martial arts clubs in Poznan do not prioritize sustainable environmental management practices, citing other priorities such as athlete comfort and organizational needs. Implementing more systematic pro-ecological actions in these facilities requires greater awareness and support in terms of knowledge and financial resources. These findings provide practical insights for martial arts clubs in Poznan, suggesting that by adopting more comprehensive sustainability practices, they can improve their environmental impact while enhancing their community engagement and organizational reputation.
