Global climate finance surpassed USD 2 trillion for the first time in 2024. Flows have grown every year over the last half-decade, despite COVID-19, energy market volatility, sovereign debt pressure, and geopolitical conflicts. This points to resilient underlying momentum and a maturing investment market for key climate solutions, not a fragile niche. While the annual rate of climate finance growth slowed to 6% in 2024, from 16% and 22% in the two previous years, the impact potential of investment is increasing. As clean technologies become cheaper, more scalable, and commercially viable, each climate dollar can deliver greater emission reductions and resilience benefits. Early policy support and investment have moved renewable energy from an emerging technology into a competitive investment opportunity. As a result, mitigation finance reached USD 1.9 trillion in 2024. There is now opportunity to expand that success across a wider range of climate solutions needed for a low-carbon, climate-resilient future. At the same time, rising costs of inaction for economies, businesses, and communities increase the urgency and scale of this need. Further acceleration must take us to at least USD 6.2 trillion annually by 20351 to ensure a climate-aligned, sustainable world where every person can thrive. […]
