At the COP29 climate summit in Azerbaijan, nearly 200 countries are negotiating a new, potentially multi-trillion-dollar annual finance goal to help poorer nations decarbonize and adapt to climate change. However, much of the proposed funding isn’t expected to come directly from governments but rather from private capital and multilateral development banks (MDBs). This approach has sparked resistance from heavily indebted developing countries, which are pushing for more public grants instead of loans.
Developed countries have already missed previous financial commitments, with the original $100 billion per year climate finance goal set for 2020 being met two years late. As the new goal is estimated at around $2 trillion annually, reliance on private finance and MDBs is likely to increase, despite these entities not being direct participants in the UN climate talks. This has created tensions, as private financial institutions and MDBs have other priorities, and their involvement raises questions about transparency and control over climate finance.

Some experts, like Chris Humphrey of the ODI Global think tank, acknowledge the limited leverage the UN has over MDBs, despite countries’ shareholding influence. Additionally, MDBs, such as the World Bank, have their own governance structures and capital constraints. Meanwhile, Wall Street has been scaling back on green investments, focusing on profit-driven opportunities rather than climate initiatives.
Developing countries are also concerned that increased reliance on private financing could obscure the actual contributions toward climate goals. Many prefer focusing on direct governmental contributions, arguing that private finance should be considered supplementary rather than a substitute for public commitments.

Ultimately, the debate at COP29 highlights the complexities of mobilizing the trillions needed for global climate action, with concerns about debt burdens, transparency, and the role of private finance shaping the negotiations.
