Are Investors Still Betting on Sustainable Finance, What the 2026 Data Actually Shows

After a rough 2025, the latest fund flow data suggests sustainable investing is finding its footing again, though not in the way the category originally expected to grow.

For a while, it looked like sustainable finance might be losing its momentum for good. Outflows piled up through 2025, product launches slowed, and the US market in particular seemed to be in a slow, steady retreat from anything labelled sustainable or ESG. The most recent data tells a more interesting story. Investors have not abandoned sustainable finance, but they have become considerably more selective about where inside it they are willing to put new money.

The Global Picture Has Turned, Cautiously

According to the latest Morningstar research, global sustainable funds attracted an estimated 3.7 billion dollars in net new money in the second quarter of 2026, excluding China, marking the second consecutive quarter of positive flows after a difficult stretch through 2025. Global sustainable fund assets climbed to roughly 3.7 trillion dollars, a new record for the category, though most of that growth came from rising markets rather than fresh investor cash, a distinction worth keeping in mind before reading too much bullishness into the headline number.

The US Just Ended a Very Long Losing Streak

The most striking piece of the latest data is what happened in the United States. US sustainable funds recorded positive net flows for the first time in nearly four years, pulling in close to 3 billion dollars in the second quarter and ending a run of fourteen consecutive quarters of outflows. US sustainable fund assets rose to a record 398 billion dollars, up thirteen percent from the previous quarter, though again, strong market performance did much of that heavy lifting rather than new subscriptions alone.

What actually pulled money back into US sustainable funds is worth paying attention to. Demand concentrated heavily around energy transition infrastructure and the technology needed to support rising power usage from artificial intelligence and data centres, a theme investors clearly find easier to embrace than broader ESG labelling. A single fund tracking smart grid infrastructure companies pulled in over 3 billion dollars in new money on its own, effectively anchoring the entire US rebound.

Passive Strategies Are Doing Most of the Work

Across both major markets, passive sustainable strategies have been absorbing new investor money while actively managed sustainable funds continue bleeding assets. That split says something important about where investor confidence actually sits right now, in low cost, rules based exposure to sustainability themes, rather than in higher fee, discretionary managers making judgment calls about what counts as sustainable.

Europe Still Dominates, but the Category Is Genuinely Global

Europe remains the clear centre of gravity for sustainable finance, accounting for roughly 84 percent of global sustainable fund assets, with the United States a distant second at around 11 percent. That said, product development has been spreading elsewhere too, with Asia accounting for half of the new sustainable fund launches globally in the second quarter, even as overall new product activity remained well below the pace seen in late 2025.

The Softer Signals Worth Watching

• New fund launches remain subdued. Thirty two new sustainable funds launched globally in the second quarter, an improvement from the prior quarter but still well below the fifty launched in the final quarter of 2025.
• Some regions are still seeing outflows. Even as the global aggregate turned positive, Asia, Canada, Australia, New Zealand, and Japan all recorded net outflows in the same quarter.
• The green bond market faces a heavy refinancing year. Green, social, and sustainability bond maturities are expected to climb to roughly 520 billion dollars in 2026, a genuine test of whether investor appetite for these instruments can absorb that much refinancing without disruption.

What Fund Managers Themselves Are Saying

The return to modest inflows in the first quarter suggests that investor appetite for sustainable strategies has not disappeared, but it remains fragile and highly region specific. Europe continues to stand out, with flows turning positive again, supported by strong demand for passive strategies. Kenneth Lamont, Principal, Manager Research, Morningstar

What we are seeing is a reset rather than a retreat. Growth is continuing, but at a slower pace, with investors becoming more selective and more focused on clarity around strategy, outcomes, and value. Kenneth Lamont, Principal, Manager Research, Morningstar

So, Are Investors Still Betting on Sustainable Finance

The honest answer is yes, but on narrower terms than the category’s earlier boom years suggested. Investors have not walked away from sustainable finance. Two consecutive quarters of positive global flows, a genuine turnaround in the long suffering US market, and record asset levels all point in the same direction. What has changed is the nature of the bet. Money is flowing toward passive, low cost vehicles over actively managed ones, toward concrete themes like energy transition infrastructure over broad ESG labelling, and toward funds that can demonstrate a clear investment case rather than a values statement alone.

Separately, survey data continues to show broad underlying interest in sustainable investing among individual investors, with younger investors showing the strongest appetite, a demographic signal that suggests demand is more likely to grow than fade as that generation’s share of investable wealth increases over time. Whether that translates into sustained fund flows at the pace seen during the category’s earlier growth years remains an open question, but the direction of travel, at least for now, points toward a market that is stabilising rather than shrinking.
