The United Nations Conference on Trade and Development (UNCTAD) has stated that the global shift to renewable energy will require over $1 trillion in annual investment by 2030. The agency warned that developing economies may fail to meet climate and energy targets without stronger inflows of foreign direct investment (FDI) and broader access to clean technologies.
This information comes from a new UNCTAD report titled 'Energy Transition Investment and the Transfer of Knowledge and Skills: Implications for Investment Treaty Design'. The report examines the financing needs for the global clean energy transition and the increasing role of private capital in renewable energy development.
According to the report, the scale of investment needed to transform the global energy system remains substantial as countries intensify efforts to reduce fossil fuel dependence and achieve net-zero emission targets. UNCTAD noted that renewable energy financing is increasingly driven by private capital, with developing economies expected to rely heavily on foreign investment to meet transition objectives.
The report states that more than 80 percent of investments across the renewable energy value chain come from private sector sources. 'Especially for developing economies, attracting foreign direct investment (FDI) may be a prerequisite for the energy transition as domestic capital and development funds are insufficient to meet projected needs,' UNCTAD said.
It added that emerging economies are gradually moving up the clean technology value chain and participating more actively in global innovation and manufacturing activities. The agency stressed that countries require not only financing but also access to advanced technologies, technical expertise, and skilled labor to effectively deploy and manage clean energy infrastructure.
UNCTAD further warned that developing economies across Africa, Asia, and Latin America continue to face major barriers to renewable energy investment despite growing global demand for cleaner energy solutions. According to the report, high borrowing costs, weak infrastructure, regulatory uncertainty, and limited access to long-term financing remain major constraints affecting renewable energy investment flows.
The agency noted that sectors such as solar, wind, battery storage, hydrogen, and electric mobility present significant economic opportunities for emerging economies if financing and technology access improve. It also highlighted the growing importance of industrial policy, innovation, and strategic partnerships in building local clean energy manufacturing capacity.
UNCTAD warned that inadequate investment mobilization could widen global inequalities, slow climate action, and expose vulnerable economies to future energy and economic shocks.
