Editorial Summary by the HealthManagement.org Team
The OECD Global Corporate Sustainability Report 2025 (GCSR 2025) offers a comprehensive overview of how the world’s corporations are managing sustainability—and where they continue to fall short. While its findings span all industries, they hold critical lessons for healthcare leaders, policymakers, and health-system executives who now recognise sustainability as integral to strategic management, governance, and patient well-being.

1. A New Era of Governance and Sustainability
The OECD grounds its report in the updated G20/OECD Principles of Corporate Governance (2023) and the OECD Guidelines for Multinational Enterprises, both of which embed sustainability and resilience directly into governance frameworks. The message is unmistakable: sustainability is no longer a “nice to have.” It has become a core component of corporate governance.
For healthcare organisations, this shift reflects what many are already experiencing. Environmental, social, and governance (ESG) issues—ranging from workforce welfare to climate resilience—now influence financial performance, reputation, and regulatory risk.

This visualises the direct, causal link between governance changes and health system outcomes, making the corporate concept immediately relevant to healthcare.
2. Disclosure: More Data, but Gaps Remain
The global disclosure landscape has grown rapidly. According to the OECD:
- About 91% of listed companies by market capitalisation now publish some form of sustainability information—up from 86% in 2022.
- Yet only around 12,900 of 44,000 listed firms disclose, suggesting that the world’s largest companies dominate the sustainability narrative.
- Coverage is uneven across sectors and geographies. The real-estate sector, for instance, has lower disclosure rates and weaker reporting on scope 3 emissions.
- Around 11,000 companies disclose direct (scope 1 & 2) greenhouse-gas emissions, while just 7,700 provide at least one category of indirect (scope 3) emissions.
CHART PLACEMENT (Section 2): A bar chart titled “Corporate Sustainability Disclosure by Sector and Market Cap, 2022–2024”. This visualises the uneven progress and the dominance of large firms, highlighting the transparency gap.
For hospitals, insurers, and public-health agencies, this transparency gap presents a direct supply chain risk. As sustainability reporting becomes standard, health-system leaders will need to evaluate their partners not only by cost and quality, but also by ESG transparency and impact.
3. Trust Depends on Assurance and Oversight
The credibility of sustainability data is just as important as the data itself. The report notes encouraging progress:
- Between 2022 and 2024, the share of sustainability disclosures receiving some form of independent assurance rose from 66% to 81% of global market capitalisation.
- However, only 17% achieved reasonable assurance—the highest verification level—while most (56%) still rely on “limited assurance.”
- The presence of board-level sustainability committees has grown significantly, reinforcing the need for board oversight of ESG performance.
For the health sector, this parallels the need for governance that treats sustainability as seriously as patient safety or financial audit—a strategic risk area that demands board attention and verified data.
4. Standard Overload and the Quest for Clarity
One of the report’s clearest warnings is the complexity of sustainability standards. The OECD identifies three major frameworks shaping the global landscape:
- GRI Standards (used by more than 6,500 companies)
- ISSB Standards (adopted by roughly 580 organisations)
- European Sustainability Reporting Standards (ESRS), newly in force since 2023
The call is for interoperability—harmonisation to reduce reporting burdens and enhance comparability.
CHART PLACEMENT (Section 4): An infographic titled “The Three Pillars of Global Sustainability Reporting—GRI, ISSB, ESRS”. This helps readers quickly distinguish between these complex and often-confusing frameworks.
Health-system managers, especially those operating internationally or sourcing from global suppliers, should stay alert to these developments. Knowing which standard a supplier follows can clarify the depth and reliability of its ESG reporting.
5. Boards, Shareholders, and Stakeholders Are Stepping Up
The governance of sustainability is now a board-room issue. In 2024:
- 70% of global market capitalisation came from companies whose boards oversee climate-related matters (up from 53% in 2022).
- Around 86% of companies disclosed shareholder-engagement policies.
- Worker representation at board level remains low globally (covering ≈ 11% of market cap), but regional differences are striking—Europe leads at 39%.
For healthcare, the message is clear: ESG must be embedded in governance structures. Hospital boards, health authorities, and public-sector agencies should establish sustainability committees and ensure representation from key stakeholders, including those from the workforce and the community.
6. Implications for Healthcare Leadership
The OECD findings translate into several key actions for the health community:
- Sustainability as a procurement criterion: Hospitals and insurers will increasingly select suppliers based on verified ESG credentials.
- Workforce and supply-chain resilience: With new focus on social governance, health-sector boards should integrate ESG metrics into HR and supply-chain due-diligence.
- Environmental health connection: Climate and environmental data have direct patient-health consequences.
- Governance and credibility: Independent assurance and strong board oversight build trust with regulators and patients alike.
- Capacity building: Health organisations must strengthen their internal capacity to interpret and act on sustainability data.
7. Challenges and Opportunities Ahead
The report highlights ongoing challenges—particularly among smaller firms and state-owned enterprises that fall behind in disclosure and assurance. Fragmented standards and materiality gaps also hinder comparability.
However, there is reason for optimism. Companies that embed sustainability within governance and strategy are demonstrating greater resilience, a principle recognised by health-system leaders. As the healthcare sector confronts increasing climate, workforce, and supply-chain challenges, aligning with OECD-level governance principles provides a roadmap for long-term sustainability and societal benefit.

Final Word
The OECD Global Corporate Sustainability Report 2025 delivers a strong call to action: sustainability must transition from the margins to the centre of corporate and public governance. For health-system leaders, it highlights that the future of healthcare management will be judged not only by financial results or clinical excellence but also by how effectively institutions uphold sustainability, transparency, and trust.
