G&A Institute's New Research Shows 2024 Sustainability Reporting Rose to Record Levels as S&P 500® Companies Reach 99% Reporting

Reporting Gap Between Large-Cap and Mid-Cap Companies Narrows with 90% Reporting Among Smaller Half of Russell 1000 ^® Companies

NEW YORK, Oct. 16, 2025 /PRNewswire/ -- 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 14th edition of G&A's annual research report is available here.

2025 Sustainability Reporting in Focus provides detailed data and findings from G&A's research into U.S. company reporting on sustainability (also called ESG, corporate responsibility, corporate citizenship, or social impact reports). G&A's team analyzes corporate reporting content including frameworks and standards used – such as the Global Reporting Initiative (GRI), Sustainable Accounting Standards Board (SASB), Task Force on Climate-Related Financial Disclosures (TCFD) – as well as alignment with initiatives such as the UN Sustainable Development Goals (SDGs), trends in external assurance, and CDP reporting. For this year's research, we also began tracking alignment with new reporting initiatives: the International Financial Reporting Standards (IFRS) Sustainability Standards, the European Sustainability Reporting Standards (ESRS), and the Task Force for Nature-related Disclosures (TNFD).

G&A's 2025 research includes sector-specific analysis of reporting trends within all 11 sectors of the Global Industry Classification Standard (GICS^®), to provide additional insights into reporting behavior per industry sector.

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 smaller half by market cap of the Russell 1000 (mid-cap companies with approximately $2 billion-$4 billion in market cap) had the greatest alignment in reporting in 2024 - reaching 90% compared to 87% 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.
  
  
• SASB continued to be the most widely used sustainability standard, with 82% of Russell 1000 reporters aligning with SASB in 2024, compared to 81% in 2023 and only 12% in 2019.
  
  
• TCFD reporting continued to increase, with 65% of Russell 1000 reporters aligning with TCFD in 2024, compared to 60% in 2023 and only 4% in 2019.
  
  
• GRI reporters remained consistent among the Russell 1000 with 55% aligning with GRI in 2024 - the same compared to 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."
