AI and Governance Leaders Unite on ESG Integration

Diligent, a global leader in governance, risk, and compliance (GRC) software, has formed a strategic partnership with Persefoni AI, a sustainability management platform used by corporations and financial institutions to measure and disclose carbon data. The collaboration seeks to strengthen corporate capacity to meet intensifying sustainability reporting requirements under evolving global frameworks.

Under the agreement, Diligent will transition its carbon accounting clients to Persefoni’s software and take an equity position in the company—an investment signaling a long-term commitment to data-driven ESG innovation. The partnership combines Diligent’s deep governance expertise with Persefoni’s carbon management and AI-powered disclosure readiness tools.

Amanda Carty, General Manager of Compliance at Diligent, described the partnership as a decisive move to equip clients for emerging regulatory and stakeholder expectations. “Persefoni’s advanced technology, compelling roadmap, and top-tier NPS among sustainability vendors make them the ideal partner for us,” she said. “We’re excited to invest in their growth and expand the possibilities for our carbon accounting clients, reinforcing our long-term commitment to the ESG market.”

Responding to Regulatory Pressure

The collaboration arrives as companies face mounting regulatory and investor scrutiny over climate disclosures. The EU’s Corporate Sustainability Reporting Directive (CSRD) is set to mandate emissions disclosure—including Scope 3 value chain data—for tens of thousands of firms operating in Europe. Meanwhile, jurisdictions across Asia and North America are adopting or aligning with the International Sustainability Standards Board (ISSB) framework, driving global demand for standardized, verifiable data.

This wave of regulation is reshaping how corporates approach ESG governance. Firms are increasingly seeking integrated solutions that unify compliance oversight, carbon accounting, and risk management into a single digital ecosystem. By combining Diligent’s governance platforms with Persefoni’s climate data capabilities, the two companies aim to provide that continuum.

Technology and Market Synergies

Persefoni’s software enables automated emissions measurement and reporting aligned with international standards such as the Greenhouse Gas Protocol and the Task Force on Climate-related Financial Disclosures (TCFD). The platform’s AI tools help users manage complex Scope 3 data and prepare for audit-grade disclosures, a feature set that is increasingly critical as sustainability reporting converges with financial reporting requirements.

“Diligent is the unquestioned global leader in Governance, Risk, and Compliance,” said Kentaro Kawamori, CEO and Co-Founder of Persefoni. “Being selected by the best is a powerful validation of our technology and vision. We’re honored to partner with their team to shape the future of sustainability together.”

For Diligent, the partnership extends its value proposition beyond board governance into full-spectrum ESG enablement—an area where client expectations are rising rapidly. The company’s platforms already support over one million governance leaders across 130 countries, and this integration aims to bring sustainability data into boardroom decision-making at scale.

What It Means for Executives and Investors

For C-suite leaders, the partnership underscores a shift toward convergence between governance and sustainability systems. Boards are no longer treating ESG as a separate disclosure exercise; it is becoming a central component of enterprise risk management and strategic planning. The Diligent–Persefoni collaboration offers companies an integrated path to address regulatory compliance while strengthening investor confidence through verifiable, transparent carbon data.

Investors and asset managers, too, stand to benefit from the interoperability of governance and carbon data systems, improving their ability to assess portfolio risk exposure and alignment with net-zero commitments.

Global Context

As sustainability regulation matures, the ability to produce accurate, auditable data is becoming a competitive differentiator. With this partnership, Diligent and Persefoni are positioning themselves at the intersection of governance technology and climate intelligence—where compliance, finance, and strategy increasingly meet.

Their combined offering reflects a broader market reality: ESG data is moving from the periphery of corporate reporting to the core of enterprise systems, reshaping how global businesses are managed, financed, and held accountable.
