ING reported €166 billion in sustainable finance volume in 2025, marking a 28 percent increase from the previous year and pushing the bank beyond the annual target it had set for 2027. The result is notable not only for its scale, but because it suggests that demand for sustainable finance remains resilient even in a market environment shaped by policy uncertainty, geopolitical tension, and uneven corporate confidence across regions.
The bank had raised its annual ambition in early 2024, moving from a previous goal of €125 billion by 2025 to €150 billion by 2027. Exceeding that higher threshold two years early indicates that sustainable finance has become a more deeply embedded part of ING’s business rather than a marginal or purely target-driven category.
Growth Was Sustained Through the Year
The 2025 figures also show that momentum strengthened as the year progressed. Sustainable finance activity reached €56 billion in the fourth quarter, making it the strongest quarter of the year. That matters because it suggests growth was not front-loaded or dependent on a narrow cluster of early transactions. Instead, the bank appears to have maintained and expanded activity through the full year.
This is important in the current market context. Sustainable finance has faced repeated questions over whether issuance and transaction volumes would weaken under political pressure, shifting regulations, or broader macroeconomic uncertainty. ING’s results suggest that, at least for a large international bank with diversified regional exposure, client demand for sustainability-linked capital remains active and commercially relevant.
Green Loans Are Gaining More Weight in the Mix
One of the more telling details in the results is the strong expansion in green loans. ING said the number of green loan transactions increased by 45 percent in 2025 and that green loans overtook sustainability-linked loans as the leading product category by number of transactions.
That shift is significant because it may reflect a broader market preference for financing tied to clearly defined use-of-proceeds structures rather than frameworks dependent on future performance targets. Sustainability-linked products remain important, but they have also faced greater scrutiny around target design, credibility, and impact. Green loans, by contrast, often offer a more straightforward link between financing and a specific environmental purpose.
If that pattern continues, it could suggest that the market is becoming more selective and more focused on products that provide clearer visibility on where capital is going and what it is supporting.
Regional Performance Shows Different Market Dynamics
EMEA accounted for the largest share of ING’s mobilised sustainable finance volume in 2025, representing 56 percent of the total. The Americas followed with 28 percent, while Asia-Pacific contributed 11 percent. Although APAC remained the smallest of the three regions by share, the bank described it as a record year for sustainable finance in the region.
These figures suggest that sustainable finance is continuing to develop unevenly across geographies, but not in a way that points to overall market retreat. Europe, the Middle East, and Africa remain the strongest base, which is not surprising given the policy architecture and institutional maturity of sustainable finance across much of the region. The Americas appear more mixed, with ING noting that steady overall volume masked a decline in private sector engagement that was offset by stronger social bond issuance from public entities.
That dynamic is worth noting because it shows how sustainable finance markets are adapting rather than moving in one single direction. In some regions, corporate demand may soften under political or economic pressure, while public sector activity or other financing categories step in to maintain overall volume.

The Results Suggest Sustainability Remains a Strategic Financing Theme
ING’s commentary points to a wider message behind the numbers. Despite shifting climate policy, geopolitical instability, and trade disruption, many organisations are continuing to treat sustainability as a strategic priority. That framing matters because it moves sustainable finance away from the idea of a cyclical or sentiment-driven category and places it more firmly in the context of long-term risk management, supply chain resilience, competitiveness, and business model transition.
For banks, that is an important distinction. If clients view sustainable finance as part of core capital planning rather than an optional overlay, then growth in this category is likely to be more durable. ING’s results suggest that this is increasingly the case, particularly where financing supports identifiable transition pathways or helps clients respond to operational and strategic pressures.
What ING’s 2025 Performance Signals
The bank’s 2025 figures show that sustainable finance continues to scale in a way that is commercially meaningful. Surpassing its annual target ahead of schedule, expanding green loan activity, and maintaining strong quarterly momentum all point to a market that is still growing, even if the surrounding narrative has become more contested.
The more important takeaway is not simply that ING had a strong year. It is that sustainable finance appears to be maturing into a more stable and diversified business line. Product preferences are evolving, regional patterns are shifting, and clients are approaching sustainability through a wider lens that includes risk, resilience, and long-term value creation.
That does not mean the market is free of pressure or contradiction. But it does suggest that sustainable finance is proving more durable than many expected, especially when tied to practical transition needs rather than broad positioning alone.
