This paper investigates the role of normative environmental configuration forces on small and medium-sized enterprises (SMEs) adopting sustainable development practices in South Africa. A research survey was performed, and data were gathered from SMEs utilizing owners and managers as respondents. Non-probability sampling at the hand of the convenience method was utilised and 220 respondents constituted the final sample. The analysis of data constituted factor analysis and hypotheses were tested through the structural equation modelling technique. The study hypothesised that normative forces have an impact on the participation of SMEs in the extents of sustainability practices, namely social, environmental and economic. The results led to the supporting of all the hypotheses postulated in the study. Thus, the major recommendation was to support the training, networking and professional affiliations of SMEs in sustainable development issues in order to ensure proliferation of sustainable development amongst these firms.
