Sustainable transport means mobility, non-reliance on fossil fuel, reliable and affordable transport; non-harmful to people, the environment and not causing climate change. Although South Africa is a lower contributor of CO₂ emission as compared to the OEDC countries, it is still a major contributor within the SADC countries. The City of Johannesburg (CoJ) is the largest city in South Africa were most of the economic transactions are taking place. Just like any other large city, it experiences over population making the transport system unsustainable. South Africa as a developing country is faced with socio-economic challenges which are hindering the development of sustainable transport. The study is conducted using the exploratory research method to explain the status quo of the transport system in South Africa as well as revealing major causes which slow down the development of sustainable transport. The exploratory research is chosen due to the early development of the literature on sustainable transport, supplier and enterprise development in South Africa.
