Abstract
The international community faces numerous sustainability challenges. In response, firms tackle these difficulties by adopting and implementing Green Supply Chain Management (GSCM) techniques. However, there has been minimal discourse in the literature concerning the institutionalisation of GSCM. This study aimed to enhance our understanding of the institutionalisation of Green Supply Chain Management, specifically concerning South African cement businesses. The study specifically examines institutionalisation from the standpoint of organisational culture. In addition to examining existing literature, the researcher intentionally selected 23 supply chain practitioners from six prominent cement companies, environmental law officials, and academics to provide their insights and perspectives on the influence of organisational culture in institutionalising Green Supply Chain Management (GSCM) within the cement industry. Thematic analysis was employed to examine primary data. The study findings indicated that the organisational culture obstructing the institutionalisation of Green Supply Chain Management (GSCM) factors comprised resistance to green policy implementation, insufficient top management support, and misalignment between green strategy and corporate goals. Conversely, the organisational culture promoting GSCM institutionalisation included human development and investment, effective communication, incentives, and a strong green culture as primary drivers. The study will inform supply chain professionals, cement company managers, environmental regulatory agencies, and NGOs about the significant influence of organisational culture on the institutionalisation of Green Supply Chain Management (GSCM). The influence of culture on the institutionalisation of Green Supply Chain Management (GSCM).
