South Africa has identified more than R60-billion of investments needed to help communities in the coal-mining Mpumalanga province as the industry gradually winds down, US Treasury Secretary Janet Yellen said as she announced an additional $45-million in grant support. The investments form part of a 1.5 trillion-rand government blueprint to reduce South Africa’s reliance on coal, which is currently used to generate more than 80% of its electricity. A group of rich countries are backing that program, known as the Just Energy Transition Plan, with $8.5-billion in climate finance in the form of concessional loans, debt guarantees and grants. The US is providing more than $1-billion.
