Cape Town’s apartheid spatial form and historically under resourced public transport system has created a resource inefficient city. Providing additional financial resources to upgrade the public transport system will not be sufficient to encourage a shift to low carbon alternatives. To create a low carbon future for Cape Town a deeper level of change is required – a radical transformation in the way different people and places are valued within the present urban context. This case study analyses a civil society movement called Open Streets through the lens of transition theory. It suggests that this movement is a niche development in which a transformation of the way people and places are valued could occur. While this movement has been well received and appears to have potential to help shift the regime of urban transport system in Cape Town, there remains a series of organisational, logistical, regulatory and funding barriers that are hampering its full development and long-term impact.
