Green supply chain management (GSCM) is an important part of most production organisations in developed countries. Meanwhile, developing countries are yet to fully embrace the concept. This study, therefore, investigated the drivers of GSCM using a close-up approach in a leading manufacturing organisation in Nigeria with sustainability initiatives. One hundred and fifty-four questionnaires retrieved from the supply chain management team of the organisation were subjected to descriptive and inferential statistics such as mean score, standard deviation, and factor analysis. Based on the results of the analyses, the drivers of GSCM in the organisation could be grouped as government-related, organisational-related, and societal-related drivers. The study concluded that synergy of the government, organisations, non-government organisations, and individual is important for achieving green supply chain practices in developing countries. It was recommended that training at all levels is essential to improve the awareness and importance of sustainable production to the environment.
