PurposeThe purpose of this paper is to examine the relationship between top management commitment and energy management in small and medium manufacturing firms in a developing country context.Design/methodology/approachThis study was executed through a survey of 66 manufacturing firms in Kampala, Uganda. The data collected were analysed using SPSS v.26.FindingsThe results show that top management commitment influences energy management. A further probe of its three dimensions of top management participation, top management support and top management beliefs reveals that all of them positively and significantly predict energy management in manufacturing firms.Research limitations/implicationsThe current study results were obtained from manufacturing small and medium firms in Kampala, Uganda. Therefore, caution should be taken prior to generalization. Furthermore, this study only focuses on top management participation, top management support and top management beliefs as the dimensions of top management commitment. This study thus provides the foundation for future studies to test other dimensions of top management commitment, particularly in other sectors.Originality/valueTo the best of the authors’ knowledge, this is the first study to examine the contribution of top management commitment dimensions top management participation, top management support and top management beliefs to energy management in a developing country context. Although all dimensions are significant, top management beliefs contribute more to energy management.
