Most Institutional Investors Maintain Positive Outlook for Sustainable Investments

Nov 20, 2025

Morgan Stanley’s 2025 Sustainable Signals survey shows asset managers and asset owners expect growth in allocations to sustainable investments, with climate adaptation and resilience growing in prominence.

Key Takeaways

  • 84% of institutional investors in the global survey expect the proportion of sustainable assets under management in their portfolios to rise in the next two years.

  • Investors are increasingly concerned about a range of challenges to sustainable investing, but see sustainability as important to managing investment risk. 

  • Energy efficiency and renewable energy remain the top two sustainable investment priorities, with climate adaptation rising to third on the list.

About eight in 10 asset managers (79%) and asset owners (86%) expect the proportion of sustainable assets under management (AUM) in their portfolios to rise over the next two years, according to the Morgan Stanley Institute for Sustainable Investing. This represents a one percentage point increase year-over-year for asset managers, but a six percentage point rise for asset owners. Asset owners who plan to increase their allocations to sustainable investments named strong financial performance and increasingly established track records among their main reasons for doing so.

 

The Institute’s latest Sustainable Signals survey polled more than 900 institutional investors globally during August and September 2025, all of whom currently or plan to practice sustainable investing. Regionally, more than 90% of North American asset owners surveyed said they expect to increase the proportion of their assets in sustainable strategies in the next two years, slightly ahead of investors in Europe (82%) and APAC (85%). 

 

“In our latest global survey of institutional investors, the majority expect to increase their proportion of assets in sustainable funds – with financial performance and a maturing track record driving these allocations,” said Jessica Alsford, Chief Sustainability Officer and Chair of the Institute for Sustainable Investing at Morgan Stanley.

Fresh Focus on Risk Management

However, respondents in this year’s survey were also more likely to highlight concerns regarding sustainable investing than in 2024, with 38% flagging a range of concerns as “very significant” compared to 25% last year.  Investors ranked data availability, fluctuating regulatory guidance and an uncertain political environment as their most significant concerns. 

 

Still, more than 80% of asset managers and asset owners polled see sustainability as an important part of managing investment risks, with around one-quarter naming portfolio risk reduction as the main reason for practicing sustainable investing. 

 

“Similar to individual investors and corporates surveyed in this year’s Sustainable Signals series, asset owners and asset managers anticipate growing impacts from climate risk in the coming years and are aligning their priorities to mitigate these challenges,” Alsford said.

Investing for Climate Adaptation and Resilience

More than 75% of institutional investors said they expect physical climate risks to have an impact on asset prices in the next five years. This echoes the Institute’s recent finding that more than 60% of companies anticipate negative impacts to their own operations from the physical effects of climate change over the same period. Investors are responding by seeking out opportunities to invest in climate adaptation and resilience strategies that can help businesses and communities withstand the physical and economic impacts of climate change, particularly data and analytics, water infrastructure and modernization of the electric grid. 

 

Globally, half of investors say that climate resilience is a core part of their risk-return model when investing in physical assets such as infrastructure or real estate, with an additional 42% considering it on a case-by-case basis.  

 

For investors in sustainable solutions, climate adaptation is moving from a niche area to a more central focus. Globally, investors ranked climate adaptation as third on their list of priority sustainability solutions in 2025, up from sixth in 2024. However, institutional investors also cited barriers to investing in climate adaptation, such as policy uncertainty, a lack of frameworks and insufficient risk models. 

 

Energy efficiency and renewable energy remained the top two investment priorities for institutional investors, across all three regions, similar to last year’s report.
