Rapid Market Expansion Driven by Climate and Tech Pressures
The global sustainable finance market is forecast to grow sixfold, reaching $35.72 trillion by 2034, up from $5.87 trillion in 2024, according to Global Market Insights. This growth is fueled by the rising frequency of extreme weather events and technological innovation.
“Growing natural and man-made catastrophic events” are a key growth driver, including floods, wildfires, and heatwaves. In 2023 alone, 387 disasters caused $223.8 billion in economic damage and impacted over 185 million people.
AI and Machine Learning Reshaping ESG Investments
Financial institutions are leveraging AI and ML to enhance ESG data analytics and investment decision-making.
For example, “In June 2023, Diligen partnered with Clarity AI to develop an ESG Module focused on climate data analysis.” This marks a shift toward algorithm-driven insights for sustainable investing.
Green Digital Finance and IoT Unlock Data-Led Sustainability
Green digital finance platforms, supported by real-time data tools and mobile access, are helping investors assess green assets more efficiently.
The National Bank of Cambodia, for instance, backed the development of a green digital finance strategy in partnership with regional think tanks. Meanwhile, IoT adoption in ESG reporting is expanding, with the global IoT market expected to grow beyond $900M in 2023 at a CAGR of 8%.
Fixed Income Leads Sustainable Investment Preferences
In 2024, the fixed income segment — especially green and social bonds — held a 41% market share. These assets offer stability and targeted environmental benefits.
In September 2024, “the International Finance Corporation (IFC) issued a green bond of $250 million to promote blue finance in developing countries.” Australia also made headlines by issuing its first $7 billion sovereign green bond in June 2024.
Institutional Investors Command the Market
Institutional investors represented 79% of the 2024 market and are forecast to maintain dominance due to their influence on corporate governance and long-term holding capacity.
J.P. Morgan launched its “Sustainable Investment Data Solutions for institutional investors in June 2023,” providing real-time ESG data insights via Fusion by JP Morgan.
Green Bonds Dominate Transaction Types
Green bonds remain the primary vehicle for funding environmentally positive projects. Corporates and municipalities now join governments in issuing these instruments.

UK and U.S. Set the Pace for Regional Growth
The UK led Europe’s sustainable finance market in 2024 with a 25% share, generating $585 billion in revenue. The country has seen a near 10% rise in circular economy investments, boosted by initiatives like sovereign green bonds and ESG integration in London’s financial hub.
Meanwhile, the U.S. is on track for significant growth, supported by green bond issuance and new sustainability finance tools. The “UN Global Compact Network USA report in February 2025” highlights the role of private sector innovation in advancing the SDGs.
China and South Africa Join the Momentum
China’s green finance evolution is gaining momentum, with joint taxonomy development led by MAS and PBOC. In South Africa, green bonds are emerging as critical tools for infrastructure development and poverty reduction.
The “African Development Bank in August 2023 confirmed that transitioning to a greener economy is one of its top strategic goals.”
