US Sustainable Investing Assets Stay Flat at $6.6 Trillion in 2025, Trade Group Says

Assets in sustainable investments totaled $6.6 trillion in 2025, versus $6.5 trillion in 2024, according to US SIF, the trade organization for the US sustainable investing industry. The assets account for 11% of the overall US market worth $61.7 trillion, down from 12% in 2024.

These assets are marketed specifically as “sustainable” or “environmental, social, and governance,” or ESG investments, according to US SIF. The percentage decline is “likely due to the increase in the overall value of the market in 2024,” according to US SIF.

Meanwhile, some 69% of the US market, or about $42.7 trillion, was covered by an active stewardship policy. Stewardship and engagement are prominent sustainable investing practices.

To make its calculation of market size, the trade group looked at Securities and Exchange Commission forms ADV for money managers and 13f for asset owners, with US registered addresses. It made adjustments for double counting. For stewardship data, it reviewed investors’ public websites, and examined their responses to the US SIF Survey, among other things.

Separately, some 25% of survey respondents have stopped using the “ESG acronym,” amid US political pushback to sustainable investing, US SIF said.

That pushback has “moderated, not reversed” activity, the group said. Some 46% of respondents reported no impact on how their organization approached sustainability, while 29% said they now focus explicitly on demonstrable financial materiality. Meanwhile, one in four have stopped using the ESG acronym.

Current investment priorities include investing in the energy transition. In terms of investment strategies, ESG integration remains the mainstream default with 77% using this approach. In addition, 46% of respondents said they expect to increase impact-investing activities over the next three years, followed by sustainability-themed investing at 43%, and ESG integration at 38%.

In a statement, Maria Lettini, CEO of US SIF, said: “What we’re witnessing is that there has not been a retreat from sustainable investing. Over three decades, we’ve seen this industry evolve from a niche concept to mainstream investment approach. The shifts we’re seeing reflect a pragmatic adaptation to the current environment while maintaining focus on the long-term drivers of value and changing market risks and opportunities.”
