How big is the Net Zero financing gap?

The report estimates that annual climate finance needs will rise to USD 6.2 trillion by 2030 and USD 7.3 trillion by 2050 to achieve Net Zero, while tracked global finance only surpassed USD 1 trillion for the first time in 2022. Transport and energy systems represent the largest investment needs, requiring at least USD 3.2 trillion and USD 2.1 trillion annually, respectively. The study highlights a significant disparity in finance distribution, with 75% of global spend concentrated in East Asia and the Pacific, Europe, and North America. It argues that public finance must act as a catalyst to mobilize private capital, particularly in developing economies where the cost of capital is significantly higher. While private sector commitments are growing—such as the 30 largest banks pledging USD 870 billion annually—the report notes that asset managers and owners have been slower to set quantifiable targets. Key recommendations include aligning stakeholder policies, supporting non-commercially viable technologies like CCUS and green hydrogen, and implementing just transition frameworks.

• There is a massive gap between current climate finance and the levels needed for Net Zero: annual requirements are estimated at USD 6.2 trillion by 2030 and USD 7.3 trillion by 2050, whereas tracked global finance only exceeded USD 1 trillion for the first time in 2022.
• Transport and energy systems are the most capital-intensive sectors for the transition, with transport requiring at least USD 3.2 trillion annually and energy systems requiring at least USD 2.1 trillion annually through 2050.
• Significant investment increases are required for other critical areas: building energy efficiency needs USD 731 billion annually, industrial processes USD 320.2 billion, clean energy storage USD 251.3 billion, and carbon capture, utilization, and storage (CCUS) USD 145.3 billion.
• Climate adaptation and resilience finance is severely underfunded, with an average annual need of USD 254 billion through 2050, while 98% of current adaptation funding is provided by public sources.
• Climate finance is geographically concentrated, with 75% of total global spending in 2019/20 occurring in Europe, North America, and East Asia and the Pacific.
• Public finance is disproportionately critical in Africa, where it comprised 86% of total climate finance over the last decade, compared to only 4% in North America.
• Private sector financial commitments are increasing, with the 30 largest global banks committing to finance USD 870 billion annually for climate solutions by 2030.
• Asset owners and managers have lagged behind commercial banks in setting specific targets; only 27% of asset owners and 2% of asset managers have publicly announced Net Zero and climate financing targets.
• Venture capital investment in climate solutions grew by 89% in 2022 to reach USD 70.1 billion, with climate-focused VC investors holding USD 37 billion in unallocated capital as of late 2022.
• Investment in the supply chain and manufacturing of clean energy solutions rose to USD 79 billion in 2022, but needs to increase by another 58% to remain on a Net Zero pathway.
• The market value for mining and processing critical minerals must triple by 2050 to USD 331.5 billion annually to support the transition.
