How Corporates Can Prepare for the Climate-Related Financial Risk Act
How Corporates Can Prepare for the Climate-Related Financial Risk Act
SB 261 mandates climate risk disclosure for companies over $500M revenue doing business in California. Learn requirements, penalties, and preparation strategies for the 2026 deadline.
For decades, climate risk was an environmental concern, something the sustainability team managed while finance teams focused on quarterly earnings. California’s Climate-Related Financial Risk Act (SB 261) shatters this silos. Effective January 1, 2026, SB 261 requires organizations to treat climate risk as a material financial issue requiring rigorous disclosure, board-level governance, and strategic mitigation.
This is the moment when climate risk moves from the ESG playbook to the CFO’s desk.
Understanding SB 261:
SB 261 is rooted in a fundamental insight: climate change poses measurable financial risks that shareholders need to understand. The law recognizes that physical risks (wildfires, floods, droughts, extreme heat), transition risks (regulatory changes, market shifts toward low-carbon alternatives), and governance risks (board oversight failures, inadequate risk management) can all trigger material financial impacts.
Who Must Comply with SB 261?
SB 261 applies to:
All business entities (corporations, partnerships, LLCs, etc.)
Operating in California with significant presence or activities
Annual revenues exceeding $500 million globally
An estimated 5,600+ organizations meet these criteria.
Timeline: First Reporting Deadline Is January 1, 2026
Companies must publish their first climate-related financial risk report by January 1, 2026.
December 1, 2025: Official CARB submission window opens
January 1, 2026: Company website publication deadline
July 1, 2026: CARB docket submission window closes
2028: Next reporting cycle begins (biennial thereafter)
Core Requirements: What SB 261 Demands
1. Climate-Related Financial Risk Assessment
Companies must analyze how climate change threatens their business.
Physical Risks:
- Exposure to extreme weather events, rising temperatures, water scarcity, sea-level rise
Governance Risks:
- Board oversight of climate strategy, executive compensation, risk management frameworks
Transition Risks:
- Regulatory changes, market shifts, technology disruption, reputational risk
2. Framework Compliance
SB 261 reports must align with one of these frameworks:
- TCFD (Task Force on Climate-related Financial Disclosures) – the most common choice
- IFRS S2 (International Sustainability Standards Board Climate Standards)
- Equivalent framework recognized by a regulated exchange or government entity
A Closer Look at TCFD Framework: The Gold Standard for SB 261 Reporting
TCFD Structure
The Task Force on Climate-related Financial Disclosures (TCFD) organizes climate risk reporting into four categories:
Governance
How is climate risk governed at the board and management level?
- Board composition and climate expertise
- Management roles and responsibilities
- How climate is integrated into executive compensation
- Board oversight mechanisms for climate risk
- Ethics and values around climate action
Example disclosure: “Our board’s risk committee meets quarterly to review climate scenarios and regulatory developments affecting our business.”
Strategy
How does climate risk influence business strategy?
- Current climate strategy and goals
- Climate scenarios analyzed (1.5°C, 2°C, 3°C+ pathways)
- Impact on revenue, costs, capital allocation
- Competitive positioning in a low-carbon economy
- Resilience plans if climate impacts worsen
Example disclosure: “We’ve committed to Net Zero by 2050 and intermediate targets for 2030, with capital investments prioritizing renewable energy and supply chain decarbonization.”
Risk Management
How are climate risks identified, assessed, and managed?
- Processes for identifying climate risks
- Integration into enterprise risk management
- Risk prioritization and mitigation strategies
- Scenario analysis outcomes
- Monitoring and escalation procedures
Example disclosure: “We conduct annual climate risk assessments across operations and supply chain tiers, prioritizing high-impact risks for mitigation planning.”
Metrics & Targets
What performance data demonstrates climate action?
- Greenhouse gas emissions (Scope 1, 2, 3)
- Climate-related capex spending
- Pay-at-risk (executive compensation) tied to climate metrics
- Renewable energy percentage
- Water usage, waste, and other climate-related metrics
Example disclosure: “We reduced Scope 1 & 2 emissions 25% since 2020 and have invested $500M in renewable energy infrastructure.”
The CFO’s Role
Historically, climate was a sustainability team responsibility. SB 261 changes this fundamentally: climate risk is now a financial reporting issue. Finance leaders must take the wheel because they understand auditability, stakeholder credibility, integration into financial statements, and cross-functional coordination.
Practical Guidance: How to Assess Your Climate-Related Financial Risks
Physical Risk Assessment
Start with exposure mapping:
1. Identify Facilities & Supply Chain Locations
- Where are your major operations (manufacturing, distribution, offices)?
- Where do key suppliers operate?
- Are these regions exposed to floods, droughts, hurricanes, wildfires, or extreme heat?
2. Assess Vulnerability
Use climate hazard maps (freely available from NOAA, NASA, or third-party providers) to evaluate exposure:
- A manufacturing facility in Arizona: drought risk (water scarcity, energy cost increases)
- A distribution center in Florida: hurricane and sea-level rise risk
- Suppliers in Bangladesh: monsoon and flooding risk
- Agricultural supply chain: drought, heat stress on crops
3. Quantify Financial Impact
- If a facility loses power for one month, what's the revenue impact?
- If a key supplier is disrupted for three months, how does that affect production?
- What's the cost to retrofit a facility for climate resilience?
4. Develop Mitigation Strategies
- Diversify suppliers geographically
- Invest in water efficiency or alternative sources
- Upgrade facilities for extreme weather resilience
- Build supply chain redundancy
Transition Risk Assessment
1. Regulatory Trends
- Track carbon pricing mechanisms (carbon tax, cap-and-trade)
- Monitor emissions standards for products and operations
- Watch for phase-outs of fossil fuel technologies
- Follow subsidy changes (incentives for renewables, penalizing carbon-intensive tech)
For example, if you manufacture natural gas appliances, you need to understand:
- Which jurisdictions are restricting gas appliance sales (CA already banned gas appliances in new construction starting 2024)?
- How quickly competitors are transitioning to electric alternatives?
- What's the capital investment needed to pivot your product portfolio?
2. Market Shifts
- Are customers demanding low-carbon alternatives?
- Are investors divesting from high-carbon sectors?
- Are competitors gaining share by offering greener products?
- What's your competitive position in a low-carbon economy?
3. Technology Disruption
- Could renewable energy alternatives disrupt your business model?
- Are electric vehicles cannibalizing fossil fuel-dependent products?
- Is carbon removal technology making your emissions-intensive products obsolete?
4. Mitigation Strategies
- Invest in R&D for low-carbon product alternatives
- Transition operations to renewable energy
- Engage with regulators on reasonable transition timelines
- Build investor confidence through credible Net Zero targets
Governance Risk Assessment
1. Board Composition
- Does your board include members with climate or energy expertise?
- Are directors overseeing climate strategy or just rubber-stamping management proposals?
- Is there a formal board committee for climate risk?
2. Executive Accountability
- Are executive compensation metrics tied to climate performance?
- Do executives have clear accountability for climate reduction targets?
- Is climate incorporated into succession planning?
3. Risk Management Maturity
- Do you have formal climate risk scenarios (not just aspirational targets)?
- Are climate risks integrated into enterprise risk management?
- Do you conduct stress tests for climate scenarios?
- Is there a clear escalation path for climate risks to the board?
Common Pitfalls & How to Avoid Them
Pitfall 1: Overstating Resilience
The Problem:
Companies often portray themselves as climate-resilient without acknowledging genuine vulnerabilities. This is risky because:
- Investors can identify overstated claims and lose trust
- If climate impacts occur and management downplayed risks, shareholder lawsuits follow
- Regulators scrutinize companies that claim "no material risks"
The Fix:
Be honest about vulnerabilities. Disclose real exposure and credible mitigation strategies. Investors respect transparency more than false assurance.
Pitfall 2: Siloing SB 261 in Sustainability
The Problem:
Relegating SB 261 compliance to the sustainability team leads to:
- Lack of financial rigor and controls
- Weak integration with financial disclosures
- Limited credibility with investors and auditors
- Restatement risk if data is later found inaccurate
The Fix:
Make the CFO and financial team responsible for SB 261 compliance. Partner with sustainability for content expertise, but house the reporting in finance.
Pitfall 3: Scenario Analysis Theater
The Problem:
Companies sometimes run climate scenarios but don't act on the insights. For example:
- Modeling a 3°C scenario revealing severe supply chain disruption but not diversifying suppliers
- Projecting regulatory carbon costs but not investing in emissions reductions
- Assessing stranded asset risks but continuing investment in the same business model
The Fix:
Link scenarios to actual strategy and capital allocation. If your scenario analysis reveals critical risks, show how you’re mitigating them, or explain why you’re not and accept the risk.
Pitfall 4: Weak Board Governance
The Problem:
Climate risk governance that doesn't cascade to decision-making:
- Board committee meets quarterly but doesn't influence strategy
- Management doesn't escalate climate risks appropriately
- No accountability mechanism if targets are missed
The Fix:
Establish clear governance: board oversight, management accountability, quarterly reporting, and metrics tied to compensation.
