NEW YORK, Oct. 15, 2025 (GLOBE NEWSWIRE) -- Governance & Accountability Institute, Inc. (G&A), a leading corporate sustainability consulting and research firm, today announced the findings of its 2025 Sustainability Reporting in Focus research report, focused on corporate reporting trends in the 2024 publication year for companies in the S&P 500® Index and the Russell 1000® Index. The research shows continued increases in sustainability reporting for both large-cap and mid-cap U.S. public companies1 - as publishing an annual sustainability report is now widely recognized as a best practice for U.S. public companies. The full report is available here.
G&A’s 2025 Sustainability Reporting in Focus is the 14th edition in its annual research series. The research provides detailed data and findings of overall sustainability reporting within these indices including analysis of report content including frameworks, standards, and initiatives used (GRI, SASB, TCFD, SDGs), trends in external assurance, CDP reporting, and sector-specific reporting trends within all 11 GICS® sectors. This year, G&A also began tracking alignment with new reporting initiatives including IFRS, ESRS and TNFD.
Key takeaways from G&A’s new research report include:
- A record 94% of Russell 1000 companies reported on sustainability in 2024, up from 93% in 2023.

- The larger half by market cap of the Russell 1000 (i.e., the S&P 500) are nearing 100% reporters with a record 99% reporting on sustainability in 2024, compared to 98.6% in 2023.

Louis Coppola, G&A’s Chief Executive Officer and Co-Founder, commented, “Over the past 14 years, our Trends research has chronicled how America’s largest public companies adopted sustainability reporting as a best practice because stakeholders demanded it, not because regulators required it. While policies may shift in Washington or Brussels, the fundamental reasons for sustainability reporting do not: the reporting process helps leaders sharpen strategy, strengthen resilience, understand risk, allocate capital, create value and build trust. That’s why the best companies keep going — and why G&A stands ready to help.”
Hank Boerner, G&A’s Chairman, Chief Strategist and Co-Founder, added, “At the heart of sustainability disclosure is a better understanding of risk and reward – something investors and stakeholders deeply appreciate. Despite the anti-ESG pushback in some quarters, Corporate America continues to innovate and push forward with more detailed and informative reporting on a widening range of topics. Companies on the leading edge of this trend are well positioned for upcoming shifts from voluntary to mandatory sustainability reporting in a growing number of jurisdictions.”
