    Due to climate change, South Africa is faced with economic and health challenges. Adopting green building technologies reduces the amount of energy usage, however the implementation of green building in South Africa has been slow. This research aimed to identify the barriers on the implementation of green building and the methods that can be adopted to enhance the growth of green building in South Africa. A qualitative research method was be adopted. The open-ended interviews were conducted with built environment professionals. The main barriers of green building implementation are: initial high cost, lack of awareness, lack of incentives, and resistance to change. Recommendations to enhance the growth of green building practices in South Africa include: updating building codes, expanding training programs, fostering collaboration between the public and private sectors, offering financial incentives, promoting the re-purposing of existing structures, and using performance-based contracts. The paper has highlighted the key barriers of green building implementation in South Africa and developed a database of the relevant studies which can further guide future researchers, stakeholders and policymakers in this area.

    Renewable energy, the just transition and inequality: insights from South Africa’s renewables procurement
    (University of the Witwatersrand, Johannesburg, 2023-06-21) Cassim, Aalia; Taylor, Julia; Crompton, Roderick; Valodia, Imraan
    Low- and middle-income countries across the world are facing the dilemma of needing to decarbonise and industrialise in the context of an electricity supply crisis. The transition from fossil fuels to renewable sources of energy is one of the first steps taken in any process of decarbonisation to address climate change. The energy transition is complex and holds significant economic risk. It requires strong governance and a capable state as well as coordination across government, community organisations and the private sector. This mammoth task requires the State to adopt policies that balance social, economic and climate objectives while reviewing past policies that may no longer be appropriate. This paper discusses the de-risking approach and the investment-centred approach to an energy transition, and using the case study of South Africa, argues for the necessity of an investment-centred approach to achieve a transition which supports local development and energy security. In analysing the example of South Africa’s Renewable Energy Independent Power Producers Procurement Programme (REI4P), we highlight important learnings for the energy transition, which provide a useful window into the wider carbon transition.
