Development banks channeled an unprecedented \$137 billion into climate finance in 2024, marking a 10% jump from the previous year. The surge came against a backdrop of heightened urgency ahead of the COP30 climate summit in Brazil, where developing nations have amplified calls for greater financial support from wealthier economies. With climate impacts intensifying through heatwaves, floods, and biodiversity loss, pressure on international financial institutions to bridge funding gaps has grown sharper than ever.

Governments in emerging economies have struggled to mobilize the trillions needed to transition to clean energy and strengthen resilience. The record financing from multilateral development banks (MDBs) reflects a coordinated response to this demand, both by expanding their own lending capacity and by leveraging their credibility to attract private capital into riskier markets.

Structural reforms and capital mobilisation

A major factor behind the rise in MDB climate finance has been internal reforms. Several of the largest development banks expanded their balance sheets and adjusted capital frameworks to lend more aggressively for climate-related projects. By reassessing risk-weighting rules and adopting guarantees against default, MDBs created headroom to channel more funds without jeopardizing credit ratings. These reforms were partly in response to international pressure after the Bridgetown Initiative and subsequent G20 discussions urged global lenders to “stretch” their balance sheets to tackle climate finance shortages.

In parallel, development banks innovated financial instruments designed to mobilize private capital at scale. Blended finance vehicles—where MDBs absorb first-loss tranches—proved instrumental in bringing commercial investors into renewable energy and adaptation projects that would otherwise appear too risky. This helped to catalyze \$134 billion in private-sector climate finance in 2024, representing a one-third increase year-on-year.

Growing role of mitigation projects

A breakdown of MDB spending shows that climate change mitigation dominated allocations, attracting nearly 70% of the total financing. Renewable energy, grid modernization, sustainable transport, and energy efficiency initiatives received priority as banks sought to accelerate global decarbonisation. Wind and solar deployment in Africa and Asia, mass electrification of public transit in Latin America, and hydrogen pilot projects in Europe and the Middle East all featured prominently in 2024 disbursements.

The strategic emphasis on mitigation reflects both investor appetite and policy imperatives. Renewable projects can generate stable cash flows, making them easier to finance compared to adaptation initiatives such as flood defenses or drought-resilient agriculture. Moreover, mitigation is essential to keep global warming within agreed targets, and MDBs see scaling clean infrastructure as their most impactful lever.

Even so, 31% of MDB climate finance was directed to adaptation projects, reflecting growing recognition that many vulnerable nations are already experiencing severe climate shocks. Adaptation finance reached \$26.3 billion, with projects ranging from coastal defense systems in island states to early-warning weather infrastructure in sub-Saharan Africa. Funding for drought-resistant seeds, water management systems, and urban heat mitigation was also scaled up, often delivered through concessional loans or grants to ensure affordability for low-income nations.

For the world’s poorest countries, MDB climate finance more than doubled over the past five years, underscoring a gradual shift toward equity in distribution. Banks acknowledged that without substantial adaptation support, gains in poverty reduction and development risk being reversed by climate-driven disasters. This focus also dovetails with political demands from the Global South, which has consistently argued that adaptation has long been underfunded compared to mitigation.

Private-sector appetite and investor confidence

Another key driver of record climate finance levels was surging interest from institutional investors. Pension funds, sovereign wealth funds, and asset managers showed greater willingness to allocate capital to sustainable infrastructure, partly due to regulatory nudges and partly because renewable energy projects have demonstrated resilience against macroeconomic shocks. MDBs played a catalytic role by de-risking projects and offering co-financing structures that reassured private investors.

The strong appetite for green bonds and sustainability-linked loans added momentum. MDBs issued record amounts of green securities in 2024, raising funds that were quickly deployed into pipeline projects. Many investors, facing rising environmental, social and governance (ESG) mandates, saw MDB-backed securities as a low-risk way to gain exposure to climate-related assets.

Geopolitical tensions and energy market volatility also factored into the financing surge. The ongoing recalibration of global energy markets, shaped by the transition away from Russian fossil fuels and by rising oil price uncertainty, reinforced the urgency of scaling renewable energy infrastructure. Policymakers and financiers alike viewed climate finance not only as an environmental necessity but also as a strategic tool for energy security and economic resilience.

The involvement of development banks in financing large-scale solar parks in India, offshore wind farms in Southeast Asia, and battery storage projects in Latin America was framed as a hedge against geopolitical energy shocks. By reducing dependence on imported fossil fuels, these projects aimed to enhance national sovereignty while aligning with global climate goals.

Pressure from civil society and political commitments

Another factor that propelled the record financing was growing accountability pressure. Civil society organizations, climate activists, and watchdog groups have intensified scrutiny of MDB commitments, demanding concrete delivery of promised climate funds. Governments facing domestic political pressure to show progress on emissions reduction and adaptation also leaned on MDBs to deliver results ahead of COP30 negotiations.

At the same time, multilateral commitments such as the Paris Agreement’s \$100 billion annual climate finance pledge have shaped MDB targets. Although that global commitment has often fallen short, MDBs have positioned themselves as leading vehicles to close the gap, keen to demonstrate relevance in the global climate finance architecture.

The rapid evolution of technology in renewable energy and climate resilience has also driven higher financing flows. Falling costs of solar panels, advances in offshore wind technology, and scalable energy storage solutions have expanded the pipeline of bankable projects. Meanwhile, digital innovations in climate risk modeling and blockchain-based finance tools have reduced uncertainty, making it easier for MDBs and investors to commit capital.

Emerging sectors such as green hydrogen, carbon capture and storage, and climate-smart agriculture also attracted substantial MDB investment in 2024. By funding pilot projects and early-stage ventures, development banks are attempting to seed future markets that can deliver outsized climate benefits once they mature.

Regional distribution and political considerations

The allocation of financing in 2024 was shaped by political as well as economic factors. Low- and middle-income countries received the majority of funding, reflecting both need and the greater marginal impact of investment. In Africa and South Asia, MDBs prioritized access to clean power, electrification, and agriculture resilience. In Latin America, the focus tilted toward sustainable transport and water management. In high-income countries, funds supported decarbonising industries and developing cutting-edge mitigation technologies.

Political considerations also influenced where MDBs directed capital. Strategic partnerships with host governments eager to showcase climate leadership created opportunities for high-visibility projects. These collaborations not only advanced climate goals but also reinforced diplomatic ties, allowing MDBs to maintain legitimacy in the eyes of both donor and recipient nations.
