Majority Want ESG 401(k) Options, Few Aware They Exist

Though a strong majority of 401(k) members show interest in sustainable investing, very few are really aware that such choices exist within their retirement plans, according to a new Morgan Stanley Institute for Sustainable Investing research. This stark disconnect in the U. S. retirement investing scene has been highlighted.

According of the research, 75% of respondents with 401(k) or similar retirement accounts say they would be interested in sustainable investments—that is, those compliant with environmental, social, and governance (ESG) standards. Financial pragmatism seems to inspire this passion more than social principles do. Many participants feel that ESG-aligned funds might provide competitive returns, thereby questioning the long-held belief that financially poorer performance comes at the expense of socially responsible investing.

Only 36% of respondents know that their plans include sustainable investing possibilities, despite the increasing interest. Among the causes of this awareness gap the paper finds are legislative uncertainty, uneven employer communication, and continuing worries regarding past poor ESG fund performance. These obstacles are preventing a significant number of retirement savers from matching their investments to their personal values or long-term sustainability objectives.

Senior behavioral insights researcher at Morningstar, Samantha Lamas, pointed out that while ESG investing has attracted notice, many individual investors give financial results top priority over social ones. "Our reports on ESG didn't find overwhelming interest, even during its heyday," she said. Many individual investors were more driven by the financial advantages of ESG rather than social goals. Her insight agrees with Morgan Stanley's discovery that sustainable investing interest is still driven by financial returns.

One still finds major disagreement over performance. From 2022 to 2024, Morningstar Direct reports, 542 U. S. -domiciled sustainable funds underperformed the Morningstar U. S. Market Index by more than seven percentage points. Investor reluctance has been exacerbated by this underperformance period. But the trend seems to be changing. Sustainable funds have averaged a 7. 23% return in 2025 till now, outpacing the 5. 99% performance of the Index. This most recent rise might help to restore faith in ESG policies and reposition them as realistic long-run investment choices.

Regulatory uncertainty adds another level of complication. The Biden administration changed the Employee Retirement Income Security Act (ERISA) rules in 2022 to permit fiduciaries to take ESG factors into account in their investment decisions provided the alternatives are financially equivalent. The amended regulation stated that a fiduciary's duty might include evaluation of climate-related risks and other ESG issues if those elements have an impact on the risk and return profile of the investment.

Proposed amendments to the rule, nevertheless, might cause legal issues. Goodwin Procter LLP wrote a legal memorandum warning that possible modifications could raise litigation risks by moving the burden of proof on investment prudence from plaintiffs to fiduciaries. Such a move may discourage plan sponsors and asset managers from providing ESG alternatives even if demand is strong. Especially given that fiduciary responsibility still worries retirement plan managers, this changing legal environment could have a chilling impact on how retirement plans view ESG integration.

The corporate reaction to employee interest in sustainable investing helps to highlight the disconnect even more. Notwithstanding compelling evidence to the contrary, the Morgan Stanley study found that 62% of companies surveyed categorized employee interest in ESG investing as either “low” or “moderate. ” Outdated ideas, too few employee surveys, or communication breakdowns between human resources departments and plan providers could underlie this misalignment.

The "do-should gap," between expressed interest and actual participation, is for professionals like Lamas both a warning sign and a possible chance. Many people may want to invest sustainably but lack of clear options, direction, or accountability measures prevents action, she said. "You need someone holding you accountable or technology that helps you," she noted. "What if, for instance, you could click a dial that includes sustainable investments into your retirement plan? "

The way ahead may depend on how well employers and plan providers convey available choices and use user-friendly tools as the regulatory environment keeps changing and sustainable funds show better performance. Closing the gap between investor interest and action will call for more than just more transparent disclosures and fiduciary clarity; it will also call for pragmatic solutions—such digital interfaces and guided decision-making—that make sustainable investing more accessible.

Overall, although sustainable investing is becoming increasingly popular among retirement savers, a lack of awareness together with regulatory ambiguity and seen performance risk is preventing usage. Better visibility, alignment, and execution will help to convert interest into participation, so clearing the path for more sustainable financial futures.
