california Climate Rules: Businesses Face new Disclosure Deadlines

Sacramento, CA – A sweeping set of climate regulations in California is poised to reshape corporate reporting requirements. Companies doing business in the state with substantial annual revenue will face new obligations to disclose climate-related risks and greenhouse gas emissions in the coming months.

Key Deadlines and Requirements

The initial deadline, set for January 1, 2026, requires companies with over $500 million in annual revenue to begin disclosing their climate-related financial risks. This represents a significant step towards greater openness about potential vulnerabilities to a changing climate. Following closely, by June 2026, businesses exceeding $1 billion in annual revenue will be mandated to report their Scope 1 and 2 greenhouse gas emissions, verified by autonomous third parties.

These regulations, stemming from California senate Bills 253 and 261, aim to provide investors, consumers, and policymakers with crucial data for informed decision-making. They are part of a broader national and international trend towards environmental, social, and governance (ESG) reporting.

Preparing for Compliance

Experts suggest businesses proactively prepare for these changes. Analyzing supply chains, assessing physical risks to assets, and accurately calculating emissions are all vital steps. Companies can draw valuable lessons from early adopters who have already begun navigating these new reporting landscapes. resources available from the California Air Resources Board prove valuable in understanding reporting nuances.

Did You Know? California is one of the first states to enact such complete climate disclosure laws, potentially setting a precedent for other regions.

Expert Insights and Guidance

A recent webinar hosted by Forvis Mazars and Gravity brought together industry professionals to discuss best practices for compliance. Presenters, including Anika Muslawski and Steve Wilkerson, shared practical insights garnered from assisting companies with their initial reports.Jay Ruckelshaus also contributed to the discussion, offering guidance on navigating the complexities of SB 253 and SB 261.

Deadline	Revenue Threshold	Requirement
January 1, 2026	$500 million+	climate-Related Financial Risk Disclosure
June 2026	$1 Billion+	Scope 1 & 2 Emissions Disclosure (Third-Party Assurance)

Pro Tip: Start collecting data now. Accurate emissions tracking and risk assessments require time and thorough analysis.

The move toward mandatory climate reporting reflects a growing awareness of the financial implications of climate change and the need for standardized, reliable information. According to a recent report by the World Economic Forum, environmental risks continue to dominate the global risk landscape.

Understanding Scope 1, 2, and 3 Emissions

To effectively comply with the new regulations, it’s crucial to understand the different scopes of greenhouse gas emissions:

• Scope 1: Direct emissions from sources owned or controlled by a company (e.g., on-site fuel combustion).
• Scope 2: Indirect emissions from the generation of purchased electricity, heat, or steam.
• Scope 3: All other indirect emissions that occur in a company’s value chain (e.g., supply chain emissions, business travel).

Understanding California’s Climate Disclosure Landscape

California is leading the nation in climate-related financial disclosure requirements. Businesses operating in the state, particularly those with annual revenues exceeding $1 billion, are now subject to stringent reporting obligations under Senate Bill 253 (SB 253) and Senate Bill 261 (SB 261). These laws, modeled after the Task Force on Climate-related Financial Disclosures (TCFD) recommendations, aim to increase transparency regarding climate risks and opportunities.This guide provides a deep dive into navigating these regulations,drawing on lessons from early adopters and offering crucial advice for those approaching compliance deadlines. Key terms include climate risk disclosure, TCFD alignment, California climate laws, and ESG reporting.

SB 253 & SB 261: A Detailed Breakdown

SB 253 mandates disclosure of Scope 1 and Scope 2 greenhouse gas emissions (GHG emissions) starting in 2026, with Scope 3 emissions reporting added in 2029.Scope 1 covers direct emissions from owned or controlled sources, while Scope 2 encompasses indirect emissions from purchased electricity, steam, heat, and cooling. Scope 3 includes all other indirect emissions in a company’s value chain.

SB 261, focused on climate-related financial risks, requires companies to report on how climate change impacts their business, strategy, and financial performance. this includes identifying physical risks (e.g., extreme weather events) and transition risks (e.g., policy changes, technological shifts). Understanding the nuances of GHG protocol, carbon footprint analysis, and climate scenario analysis is paramount.

Insights from Early Adopters: lessons Learned

Several companies proactively began climate disclosure reporting before the mandate.Their experiences offer valuable insights:

* Data Collection is the Biggest Hurdle: Early adopters consistently cite the difficulty of gathering accurate and comprehensive data, particularly for Scope 3 emissions.investing in robust data management systems and establishing clear data collection protocols is crucial.

* Cross-Functional Collaboration is Essential: Triumphant implementation requires collaboration between sustainability, finance, operations, and risk management teams. Siloed approaches lead to inconsistencies and inaccuracies.

* Materiality Assessments are Key: Focusing on climate-related risks and opportunities that are material to the business – those that coudl significantly impact financial performance – streamlines the reporting process and enhances relevance.

* Third-Party Assurance Builds Credibility: Seeking self-reliant verification of reported data enhances trust and demonstrates a commitment to transparency.Climate assurance, ESG verification, and sustainability reporting assurance are becoming increasingly common.

Essential Late-Stage Tips for Compliance (2025-2026)

For companies facing imminent reporting deadlines, here’s a focused action plan:

1. Gap Analysis: Conduct a thorough assessment of current reporting capabilities against SB 253 and SB 261 requirements. Identify data gaps, process deficiencies, and areas needing enhancement.
2. Prioritize Scope 1 & 2 Emissions: Focus initial efforts on accurately calculating and reporting Scope 1 and 2 emissions. These are the immediate reporting requirements. Utilize tools like carbon accounting software and emission factor databases.
3. Develop a Scope 3 Roadmap: While Scope 3 reporting isn’t required until 2029, begin planning now. Identify key Scope 3 categories,assess data availability,and develop a phased approach to data collection.
4. Climate Risk Assessment: Perform a comprehensive climate risk assessment, considering both physical and transition risks. Utilize frameworks like the TCFD to structure the assessment and identify potential impacts.
5. Governance & Oversight: Establish clear governance structures and assign duty for climate disclosure reporting. Ensure executive-level oversight and accountability.
6. Legal Counsel Review: Engage legal counsel specializing in environmental regulations to ensure compliance with all applicable laws and regulations.

Navigating the Complexity of Scope 3 Emissions

Scope 3 emissions frequently enough represent the largest portion of a company’s carbon footprint, making them the most challenging to measure and report. Strategies for tackling Scope 3 include:

* Supplier Engagement: Collaborate with suppliers to collect data on their emissions. Encourage them to adopt enduring practices.

* Spend-Based Data: Utilize spend-based data and emission factors to estimate emissions from purchased goods and services.

* Industry-Specific Methodologies: Leverage industry-specific methodologies and best practices for calculating Scope 3 emissions.

* Life Cycle Assessments (LCAs): Conduct LCAs to assess the environmental impact of products and services throughout their
