Part of a new industry series Investing the Future™: Climate Risk Intelligence™ for Private Equity
Executive Summary
Private equity is moving from climate awareness to climate exposure management. The scale is material: the PEI 300 reported that the world’s largest private-equity firms raised $3.29 trillion over the five years through 2024, while Swiss Re estimated $318 billion in global natural-catastrophe losses in 2024, including a $181 billion protection gap. Those pressures now flow directly into portfolio value through property damage, business interruption, supply-chain and utility disruption, insurance cost and availability, refinancing conditions, and exit diligence. At the same time, IFRS S2 and California’s SB 261 are making climate-related financial risk analysis more finance-grade, pushing resilience planning and disclosure readiness into diligence, portfolio management, lender conversations, and exit quality (MSCI, 2024; Private Equity International, 2025; Swiss Re Institute, 2025; California Air Resources Board, 2026).
Private Equity Faces A Climate Risk Inflection Point
Private equity now sits at a climate inflection point. For purposes of sector analysis, private equity is best understood as part of the capital markets and investment management side of BFSI: it raises capital, allocates it through control-oriented private investments, influences governance at portfolio companies, and interacts directly with lenders, insurers, auditors, advisors, and limited partners. The PEI 300 reported that the world’s largest private-equity firms raised $3.29 trillion over the five years through 2024; based on PEI’s firm-level figures, the top 10 alone accounted for $780.7 billion, or 23.7 percent, of that total (MSCI, 2024; Private Equity International, 2025).
Physical Climate Risk Now Hits Portfolio Value Through Multiple Channels
That scale matters because physical climate risk now transmits into private-equity value through multiple financial channels: property damage, business interruption, supply-chain disruption, utility failure, insurance cost and availability, refinancing conditions, and exit diligence. Swiss Re estimated global natural-catastrophe losses at $318 billion in 2024, with $137 billion insured and a $181 billion protection gap. For private-equity sponsors, that gap is not an abstract macro statistic; it is a reminder that uninsured or underinsured losses can reappear inside EBITDA, working capital, capex, and recovery time during a standard hold period (Swiss Re Institute, 2025; Swiss Re, 2025).
Disclosure Expectations Are Becoming More Finance-Grade
Reporting expectations are also becoming more finance-grade. IFRS S2 is effective for annual reporting periods beginning on or after January 1, 2024. In the IFRS Foundation’s 2024 progress report on climate-related disclosures, 82 percent of companies disclosed at least one of the 11 TCFD-recommended disclosures for fiscal year 2023, but only 44 percent disclosed at least five and roughly 3 percent disclosed all 11. The least-disclosed item remained resilience of strategy under different climate scenarios, at 11 percent, which is directly relevant to private-equity decisions about physical risk, contingency planning, and adaptation (IFRS Foundation, n.d.; IFRS Foundation, 2024).
California SB 261 Brings Climate Risk Into The Private-Market Operating Model
California’s SB 261 brings the issue directly into the private-market operating model. According to the California Air Resources Board, the law applies to both public and private U.S. companies doing business in California with annual revenue above $500 million and requires biennial climate-related financial risk reports that describe the risks identified and the measures adopted to reduce and adapt to them. CARB has stated that the first reports are due on or before January 1, 2026, and announced on February 26, 2026, that more than 120 reports had already been voluntarily submitted and made public. The strategic implications for private equity are clear: physical risk analysis, resilience planning, and disclosure readiness can no longer be treated as occasional ESG exercises. They now shape diligence, portfolio management, insurance renewal, lender conversations, and exit quality (California Air Resources Board, 2025a, 2025b, 2026).
Frequently Asked Questions (FAQs)
- Why is private equity considered to be at a climate inflection point? Private equity now faces climate risk as a direct investment and portfolio-management issue rather than a peripheral ESG topic. Because firms raise capital, influence governance at portfolio companies, and interact with lenders, insurers, advisors, and limited partners, physical climate risk now affects value creation, risk oversight, financing, and exit outcomes across the private-equity model (MSCI, 2024; Private Equity International, 2025).
- How does physical climate risk affect private-equity portfolio value? Physical climate risk can reduce value through several channels, including property damage, business interruption, supply-chain disruption, utility failure, insurance cost and availability, refinancing conditions, and exit diligence. For sponsors, those impacts can show up in EBITDA, working capital, capex requirements, recovery time, and ultimately valuation during a standard hold period (Swiss Re Institute, 2025; Swiss Re, 2025).
- What does the protection gap mean for private-equity investors? The protection gap is the difference between total economic losses and insured losses. Swiss Re estimated global natural-catastrophe losses at $318 billion in 2024, with $137 billion insured and a $181 billion protection gap, which matters to private equity because uninsured or underinsured losses can remain inside the portfolio company and directly affect operating and financial performance (Swiss Re Institute, 2025; Swiss Re, 2025).
- Why do IFRS S2 and climate disclosure trends matter to private equity? They matter because climate-related risk reporting is becoming more finance-grade and more decision-relevant. IFRS S2 is effective for annual reporting periods beginning on or after January 1, 2024, and the IFRS Foundation’s 2024 progress report shows that companies still disclose climate information unevenly, especially around resilience under different climate scenarios. That gap is highly relevant to private-equity diligence, contingency planning, and adaptation strategy (IFRS Foundation, n.d.; IFRS Foundation, 2024).
- How does California SB 261 affect the private-equity operating model? California SB 261 applies to both public and private U.S. companies doing business in California with annual revenue above $500 million and requires biennial climate-related financial risk reports describing identified risks and the measures adopted to reduce and adapt to them. For private equity, that means physical risk analysis, resilience planning, and disclosure-readiness now have direct implications for portfolio management, insurance renewal, lender conversations, and exit quality (California Air Resources Board, 2025a, 2025b, 2026).
