The UK-funded technical climate assistance programme Climate Finance Accelerator (CFA) South Africa has launched a fourth call for proposals for low-carbon businesses seeking investment for projects in the energy, transport, waste management, water and sustainable agriculture sectors.

The projects must have completed a full feasibility study and require a minimum investment of $3-million.

Applications are open from December 10 to February 6, 2026.

The CFA helps make climate projects more bankable and attractive to investors by providing tailored support. Since its launch, CFA South Africa has facilitated close to $100-million in climate finance across its first three iterations.

Selected businesses will benefit from group workshops and one-on-one guidance from financial, technical and gender equality, disability and social inclusion experts, increasing their chances of securing funding, the CFA says.

“South Africa needs bold, investment-ready climate solutions and the CFA remains one of the most effective platforms for helping low-carbon businesses strengthen their bankability,” says business organisation National Business Initiative CEO Shameela Soobramoney.

“This new call for proposals is a chance to accelerate impact and secure the funding needed to scale. I encourage all eligible low-carbon project developers to apply. With the right support and investment, energy, water, transport, waste and sustainable agriculture projects can deliver real economic, social and climate gains for our country,” she says.

“As part of the UK–South Africa partnership on climate change, including through the Just Energy Transition Partnership, I am delighted that CFA South Africa is now open for applications,” says British High Commissioner to South Africa Antony Phillipson.

“This hugely successful programme has already supported some of the country’s most innovative low-carbon businesses, with more than $100-million invested in CFA alumni. It is a demonstrable example of the UK’s continued commitment to support a fair and inclusive shift to a sustainable, low-carbon future,” he says.

Over the past three CFA South Africa iterations, 43 projects received capacity-building support, including technical and financial training.

Direct engagement with local and international investors has led to investment decisions exceeding $100-million.
