The report was produced by academics at South Africa's Stellenbosch University in conjunction with the Blended Finance Taskforce, a body set up in 2017 to help mobilise large-scale private capital in a bid to end poverty in line with the United Nations' Sustainable Development Goals.
South Africa is the world's 12th biggest emitter of climate warming gases and the biggest in Africa. In November, the United States, Britain, France, Germany and the European Union agreed to offer an $8.5bn package to help South Africa accelerate its transition from coal, although exact details and timelines are still being discussed.
Besides building up renewable projects and infrastructure, funding is also earmarked for gas plants and energy flexibility, new transmission lines as well ensuring that thousands of coal workers whose jobs are threatened will be reskilled, a political hot potato for the ruling African National Congress government and its labour allies.
"Aligning the right type of capital with the right investments and costs is key to meeting South Africa's just energy transition objectives," the report said, adding that the definition of "just" should extend beyond workers to address the challenges of communities in coal-dependent areas.
