Infrastructure implications of a green economy transition in the Western Cape Province of South Africa: A system dynamics modelling approach

In order to meet future goals in reducing the resulting carbon emissions from transport networks, vast investment in the development of a more energy-efficient and sustainable infrastructure is required. This study investigates the infrastructure implications of a green economy transition in the Western Cape Province of South Africa with a particular focus on the transport sector. Utilising a system dynamics modelling approach, the research effort aimed to improve understanding of how technical, economic, political, social, and environmental factors interact, particularly in the context of the uncertainties encountered during this transition. The key findings of the research indicate that investment in a better public transport system, as well as shifting the movement of freight onto the rail network, would deliver long-term positive effects, including a possible carbon emission reduction of up to 17.89%.
