Climate-related financial disclosure has moved from voluntary best practice to regulatory requirement. Companies worldwide now face mandatory rules requiring them to report how climate change affects their business—and what they’re doing about it. Understanding these requirements is essential for compliance teams, CFOs, and sustainability professionals navigating an increasingly complex disclosure landscape.
What Is Climate-Related Financial Disclosure?
Climate-related financial disclosure is the process of communicating climate risks, opportunities, and impacts to investors, regulators, and other stakeholders through financial reporting. The goal is to provide decision-useful information that helps investors understand how climate change might affect a company’s financial performance and long-term viability.
Unlike traditional sustainability reports that focus on environmental stewardship, climate-related financial disclosure connects climate issues directly to financial outcomes. It addresses questions investors increasingly ask: How might carbon pricing affect operating costs? What physical risks threaten facilities and supply chains? How is the company positioned for the transition to a low-carbon economy?
The distinction matters because financial disclosure carries different expectations than voluntary sustainability reporting. Financial disclosures must be accurate, consistent, and comparable—subject to the same rigor as other information in annual reports and SEC filings.
The Four Pillars of Climate Disclosure
The Task Force on Climate-related Financial Disclosures (TCFD), established by the Financial Stability Board in 2015, created the foundational framework that now underpins global climate disclosure standards. TCFD organized disclosure requirements around four pillars:
Governance
Governance disclosure explains how the organization oversees climate-related risks and opportunities. Companies must describe the board’s role in climate oversight, management’s responsibilities, and the processes that connect climate considerations to strategic decisions. Investors want to know that climate risk has attention at the highest levels.
Strategy
Strategy disclosure addresses how climate change affects the business model. This includes identifying climate-related risks and opportunities over different time horizons, describing their impact on business operations and financial planning, and demonstrating resilience through scenario analysis. Companies must show they’ve considered multiple climate futures—not just business as usual.
Risk Management
Risk management disclosure explains how the organization identifies, assesses, and manages climate risks. This pillar requires companies to describe their processes for evaluating climate threats, how climate risk integrates with enterprise risk management, and the criteria used to prioritize climate-related issues. It demonstrates that climate risk isn’t siloed but embedded in core business processes.
Metrics and Targets
Metrics disclosure provides quantitative data on climate performance. At minimum, companies must report greenhouse gas emissions across Scope 1 (direct), Scope 2 (purchased energy), and increasingly Scope 3 (value chain). They must also disclose climate-related targets and progress against them. This pillar transforms climate commitments from aspirations into measurable accountability.
Key Disclosure Frameworks and Regulations
The disclosure landscape has evolved rapidly as voluntary frameworks become mandatory requirements. For a detailed side-by-side breakdown of how each standard handles physical risk, scenarios, and timelines, see our climate disclosure frameworks comparison.
TCFD to ISSB
The TCFD completed its mandate in October 2023 when the International Sustainability Standards Board (ISSB) took over responsibility for climate-related disclosure standards. IFRS S2 Climate-related Disclosures, issued in June 2023, incorporates and builds on TCFD recommendations. It adds industry-specific requirements derived from SASB Standards and requires more detailed scenario analysis. Jurisdictions adopting ISSB standards make these requirements legally binding.
European Union
The EU’s Corporate Sustainability Reporting Directive (CSRD) mandates detailed climate disclosure for large companies and listed SMEs operating in Europe. CSRD goes beyond TCFD by requiring “double materiality”—companies must report both how climate affects their finances and how their operations affect the climate. The European Sustainability Reporting Standards (ESRS) provide implementation guidance.
United States
The SEC finalized its climate disclosure rule in March 2024, requiring public companies to disclose material climate risks, Scope 1 and 2 emissions, and climate-related targets. The rule aligns with TCFD but faced legal challenges that paused implementation. Despite federal uncertainty, momentum continues at state and corporate levels.
California
California’s climate disclosure laws (SB 253 and SB 261) require large companies doing business in the state to report greenhouse gas emissions and climate-related financial risks—regardless of where they’re headquartered. SB 253 covers Scope 1, 2, and 3 emissions for companies with over $1 billion in revenue. SB 261 requires climate risk reports for companies with over $500 million in revenue.
What Information Must Be Disclosed
Across frameworks, certain disclosure elements appear consistently:
Greenhouse gas emissions form the quantitative foundation. Scope 1 covers direct emissions from owned sources. Scope 2 covers indirect emissions from purchased electricity, heat, and steam. Scope 3—the most challenging—covers value chain emissions including suppliers, product use, and employee commuting. Most frameworks now require or strongly encourage Scope 3 reporting.
Climate-related risks must be identified and assessed. Companies need to distinguish between physical risks (acute events and chronic shifts) and transition risks (policy, technology, market, and legal changes). Material risks require disclosure of potential financial impacts and management strategies.
Scenario analysis demonstrates strategic resilience. Companies must show how their business performs under different climate futures—typically a 1.5°C or 2°C aligned scenario versus a higher warming pathway. This analysis reveals vulnerabilities and adaptation needs.
Targets and transition plans show commitment to action. If a company has set emissions reduction targets or net-zero commitments, frameworks require disclosure of those targets, the baseline, interim milestones, and progress to date.
How to Prepare for Climate Disclosure Requirements
Organizations facing disclosure requirements should take a structured approach:
Assess current state. Conduct a climate audit to map existing data collection, reporting processes, and governance structures against disclosure requirements. Identify gaps between what you currently report and what frameworks require.
Establish governance. Ensure board-level oversight of climate risk. Define management roles and reporting lines. Document the processes that integrate climate into strategic planning and risk management.
Build data infrastructure. GHG emissions data—especially Scope 3—requires robust collection systems across operations and supply chains. Physical risk assessment needs location-level data on climate hazards across facilities and key suppliers.
Conduct scenario analysis. Work through how different climate pathways affect your business model. Most frameworks expect analysis under at least two scenarios—a Paris-aligned pathway and a higher warming scenario.
Start reporting voluntarily. Companies not yet subject to mandatory rules benefit from voluntary disclosure. It builds internal capabilities, identifies data gaps, and demonstrates commitment to transparency before requirements take effect.
For physical risk data supporting climate disclosure, automated platforms now provide scenario-based assessments across multiple hazards and time horizons—delivering the location-level analysis that disclosure frameworks require without lengthy consulting engagements.
Frequently Asked Questions
What is the difference between TCFD and ISSB?
TCFD created the foundational voluntary framework for climate disclosure. The ISSB took over in 2023 and incorporated TCFD recommendations into mandatory global standards (IFRS S2). ISSB builds on TCFD by adding industry-specific requirements and more detailed scenario analysis expectations.
Who is required to make climate-related financial disclosures?
Requirements vary by jurisdiction. The EU’s CSRD covers large companies and listed SMEs in Europe. California’s SB 253/261 applies to large companies doing business in the state. The SEC rule targets public companies. Many companies voluntarily disclose ahead of mandatory requirements.
What are Scope 1, 2, and 3 emissions?
Scope 1 covers direct emissions from sources you own or control. Scope 2 covers indirect emissions from purchased electricity, steam, heating, and cooling. Scope 3 covers all other indirect emissions in your value chain, including suppliers, transportation, product use, and employee commuting.
What is scenario analysis in climate disclosure?
Scenario analysis examines how your business would perform under different climate futures. Frameworks typically require analysis under a Paris-aligned scenario (1.5°C or 2°C warming) and a higher emissions scenario. This demonstrates strategic resilience and reveals climate-related vulnerabilities.
How do I get physical risk data for climate disclosure?
Physical risk data requires assessment of climate hazards at specific locations—your facilities, supply chain nodes, and critical assets. Automated platforms can provide scenario-based risk assessments across multiple hazards and time horizons, delivering the location-level data disclosure frameworks require.
Key Takeaways
Climate-related financial disclosure has evolved from voluntary best practice to regulatory mandate across major economies. The TCFD framework—now embedded in ISSB standards, EU CSRD, and emerging US requirements—organizes disclosure around governance, strategy, risk management, and metrics. Companies must report greenhouse gas emissions, climate-related risks, scenario analysis, and progress toward targets. Starting early builds capabilities and demonstrates commitment to the transparency that investors and regulators increasingly demand.
