The OECD Clean Energy Finance and Investment Mobilisation (CEFIM) Programme was launched in 2019 by the Organisation for Economic Co-operation and Development (OECD). Originally introduced in Colombia, India, Indonesia, Thailand, and Vietnam, CEFIM now also encompasses Egypt, the Philippines, and South Africa. Denmark has supported CEFIM with a Voluntary Contribution of DKK 35 million during 2019-2024, focusing on grid-scale renewable power and energy efficiency. An additional DKK 40 million has been reserved for a proposed Phase II of Danish support for the CEFIM over 2024-2028. PEMconsult serves as process consultant in the formulation of this new phase of proposed support, in a contract with the Department for Green Diplomacy and Climate of the Ministry of Foreign Affairs of Denmark, and in close liaison with the Danish Ministry of Climate, Energy and Utilities, and OECD. Key aspects of the project formulation include eliciting results and lessons of the first phase of support and OECD’s comparative strengths in the complex and dynamic institutional architecture related to the clean energy transition, and considerations linked to (i) the potential of deepening existing CEFIM programmes in India, Indonesia, and Vietnam, including support for country platforms such as the Just Energy Transition Partnerships (JETPs), (ii) expanding collaboration to new locations not previously supported by Denmark, (iii) and intensifying knowledge exchange and capacity building across countries and regions.
