Winter 2026 ESG Investing Quarterly Update

Key Takeaways

• Trump EO orders SEC review of proxy advisor rules.
• ISS and Glass Lewis shift to case‑by‑case ESG voting.
• Texas anti‑ESG law struck down as unconstitutional.
• House passes pecuniary‑only fiduciary bill, moves to Senate.
• NZAM eases commitments, drops 2050 timeline.

Summary

The White House issued a December 2025 executive order directing the SEC, FTC and DOL to review proxy‑advisor regulations and ERISA rules, prompting ISS and Glass Lewis to overhaul their ESG voting policies. Federal legislation is moving toward a “pecuniary‑only” fiduciary standard, with the House passing H.R. 2988 and Senate bills S. 3086 and S. 3083 pending. State courts have struck down Texas’s anti‑ESG law as unconstitutional, while Michigan proposes similar fiduciary limits and California advances climate‑disclosure rules. Industry groups such as NZAM are revising commitments amid heightened scrutiny from regulators and investors.

Pulse Analysis

Federal action on ESG has accelerated dramatically. President Trump’s executive order compels the SEC to reassess proxy‑advisor oversight, the FTC to probe antitrust concerns, and the DOL to rewrite ERISA guidance, all aimed at curbing perceived political bias in shareholder voting. In response, the two dominant proxy firms, ISS and Glass Lewis, are abandoning blanket ESG policies in favor of client‑specific, case‑by‑case analyses, signaling a broader industry retreat from standardized sustainability voting.

At the state level, courts and legislatures are redefining the ESG landscape. A Texas federal judge declared the state’s anti‑ESG statute unconstitutional, citing First‑Amendment violations, while Michigan’s new bill seeks to lock fiduciaries into purely financial decision‑making unless proxy advisors adopt similar standards. Meanwhile, California’s climate‑disclosure regime faces mixed judicial outcomes, with the Ninth Circuit halting one rule but allowing another, prompting the California Air Resources Board to adjust reporting timelines and open voluntary filing windows. These divergent approaches create a patchwork of compliance requirements for investors operating across multiple jurisdictions.

Industry actors are adapting to the uncertainty. The Net Zero Asset Managers initiative has softened its commitments, removing the 2050 deadline and reframing climate considerations as fiduciary duties, a move that may ease adoption for firms wary of regulatory backlash. Simultaneously, the New York City Comptroller’s public criticism of a major equity manager underscores the growing pressure from public pension overseers to align stewardship with evolving ESG expectations. Collectively, these developments suggest that ESG investing will remain a contentious, highly regulated arena, demanding agile governance structures and vigilant legal monitoring.
