A Turning Point for Large Unlisted Companies

For years, sustainability reporting in the Philippines was largely associated with publicly listed companies (PLCs). But starting 2025, the Securities and Exchange Commission (SEC) has expanded its sustainability reporting requirements to include Large Unlisted Companies (LNLs).

This mandate signals a new reality: whether listed or not, companies with significant market impact must now demonstrate transparency, accountability, and commitment to ESG principles.

Why Are LNLs Being Included?

LNLs form the backbone of many Philippine industries. Their scale of operations means they contribute significantly to economic activity, resource use, and environmental impact. By requiring sustainability reports, the SEC aims to:

• Raise transparency and accountability across the corporate sector
• Improve access to green financing and investment
• Encourage climate action and net zero alignment across industries
• Position the Philippines closer to global ESG reporting standards

What Does SEC Require? 

The SEC’s Sustainability Reporting Guidelines outline what LNLs need to disclose:

• Material ESG issues that directly affect operations and stakeholders.

   

• Alignment with IFRS S1, IFRS S2, TCFD, and GRI frameworks
• Governance structures for corporate responsibility and sustainability oversight
• Quantifiable climate and ESG metrics, including net zero commitments.

Opportunities Beyond Compliance

While some companies may see this as just another compliance task, forward-looking LNLs can leverage sustainability reporting as a:

• Competitive advantage – Demonstrating leadership in ESG builds investor and consumer trust
• Financing opportunity – Green financing and sustainability-linked loans increasingly require robust ESG disclosures
• Resilience strategy – Embedding ESG into corporate governance strengthens risk management against climate and market disruptions

The Consultant Advantage

Many LNLs may lack in-house ESG expertise, which makes partnering with a sustainability consultant vital. At GCSS, Inc., we help LNLs:

• Conduct materiality assessments
• Map disclosures to global frameworks (IFRS, TCFD, GRI)
• Establish data systems for assured, investor-grade reporting
• Craft reports that are not just compliant, but credible and future-proof
