However, it operates in cooperation with regional development banks, including the African Development Bank (AfDB), Asian Development Bank (ADB), European Bank for Reconstruction and Development (EBRD) and the Inter-American Development Bank (IDB), and serves as an interim source of finance. The USD 5.8 billion Clean Technology Fund aims to promote the transformation in developing countries by providing funding to scale-up the demonstration, deployment and transfer of low-carbon technologies with significant potential for long-term greenhouse gas emissions reductions (CIF 2021; Climate Funds Update 2021).

As of September 2021, the CTF currently finances 19 country programmes and one regional programme with over 90 individual projects.

Application process and project preparation

Public sector:
  1. Joint assessment of interested eligible countries’ investment potential to meet CTF investment criteria through MDBs
  2. Joint exercise for potential fit to discuss the ability of CTF to finance low carbon activities together with interested governments, private industries and other stakeholders
  3. Elaboration of an investment plan under the leadership of the recipient country
  4. Review of the investment plan by CTF Trust Fund with a view to approving a budget envelope for programmes/projects and authorising the designated MDBs to proceed with the development and preparation of individual investment projects for CTF co-financing
Private sector:
  • Submission of proposals in the form of either individual large-scale projects (“Projects”) or programme envelopes aggregating several small and medium sized projects each utilising less than USD 50 million of CTF funds and all having a shared focus and objective (“Programmes”)
  • Explanation of expected contributions of projects and programmes towards achieving transformation outcomes in in a sector, sub-sector, country, sub-national region, sub-region, or region within the proposal
  • Demonstration required that these outcomes would not be possible without support from the CTF
