What is California’s Climate Corporate Data Accountability Act (SB 253)?

California’s Climate Corporate Data Accountability Act, commonly called SB 253, is a transformative piece of legislation aimed at increasing corporate transparency and accountability in reporting greenhouse gas (GHG) emissions. This law mandates large public and private companies doing business in California, with revenues over $1 billion, to disclose their GHG emissions, covering Scope 1, Scope 2, and Scope 3 emissions.

What is SB 253?

SB 253 is a legislative act designed to enhance transparency in corporate emissions reporting. It requires comprehensive disclosure of GHG emissions from companies operating within California that meet certain revenue thresholds. The goal of SB 253 is to provide stakeholders, regulators, and the public with credible and transparent climate information, ultimately driving significant carbon reductions and aligning with California’s broader climate goals.

How Does SB 253 Work?

SB 253 works by establishing a phased approach for businesses to report their GHG emissions. It mandates the reporting of direct emissions (Scope 1), indirect emissions from energy consumption (Scope 2), and other indirect emissions typically from the supply chain (Scope 3). The law also enforces third-party verification of the reported data to ensure accuracy and reliability.

Key Phases of SB 253 Implementation:

  1. Initial Reporting: Starting in 2026, companies will report Scope 1 and Scope 2 emissions annually, using data from the prior year (2025).
  2. Expanded Reporting: Scope 3 emissions will also be reported annually, beginning in 2027, based on 2026 data.
  3. Verification: The process begins with limited third-party assurance, with increasing rigor over time, transitioning to full reasonable assurance by 2030.

What are the Requirements of SB 253?

SB 253 imposes several critical requirements on affected businesses:

  • Comprehensive Emissions Reporting: Companies must disclose their Scope 1, Scope 2, and Scope 3 emissions following the Greenhouse Gas Protocol standards.
  • Third-Party Assurance: Initial limited assurance for Scope 1 and 2 emissions, transitioning to reasonable assurance by 2030. Scope 3 emissions will require limited assurance pending CARB review.
  • Public Registry: Emissions data must be reported via a new public registry administered by the California State Air Resources Board (CARB).
  • Penalties for Non-Compliance: Penalties up to $500,000 for non-compliance, with safe harbour provisions for businesses making reasonable efforts to report Scope 3 emissions accurately.

When Does SB 253 Become Mandatory?

The phased implementation of SB 253 gives businesses time to prepare:

  • 2026: Mandatory reporting for Scope 1 and 2 emissions based on 2025 data.
  • 2027: Mandatory reporting for Scope 3 emissions based on 2026 data, with Scope 3 reports required no later than 180 days after Scope 1 and 2 reports.
  • 2030: Scope 1 and 2 emissions will require reasonable assurance, while Scope 3 will require limited assurance, pending CARB review.

Who Needs to Comply with SB 253?

SB 253 applies to large public and private companies with annual revenues exceeding $1 billion and doing business in California. This broad scope includes an estimated 5,400 companies across various industries. The definition of "doing business in California" will be clarified through implementing regulations but is generally expected to cover:

  • Engaging in financial transactions within California.
  • Being organized or commercially domiciled in California.
  • Exceeding certain thresholds for sales, property, or payroll within the state.

Why Should You Care About SB 253?

Understanding and complying with SB 253 is crucial for several reasons:

Enhanced Corporate Responsibility

SB 253 holds companies accountable for their environmental impact, encouraging the adoption of sustainable practices and reducing carbon footprints.

Competitive Advantage

Early compliance can provide a competitive edge. Companies demonstrating leadership in sustainability can attract more investors and customers who prioritize environmental responsibility.

Investor Confidence

Transparent and accurate emissions reporting boosts investor confidence as investors increasingly seek reliable data to assess climate-related financial risks.

Global Alignment

SB 253 aligns with global sustainability initiatives, making it easier for companies to standardize emissions reporting across multiple jurisdictions.

Avoiding Penalties

Non-compliance can result in significant financial penalties. Adhering to SB 253 ensures businesses avoid these penalties and maintain regulatory compliance.

How to Prepare for SB 253

Preparing for SB 253 requires a strategic approach to data collection and reporting across your entire business and supply chain. Companies that get ahead of these requirements will be better positioned to meet compliance and leverage the regulation for competitive advantage.

Here’s how to start:

1. Supply Chain Data Collection

Gather comprehensive data on GHG emissions throughout your supply chain. This means working closely with suppliers to track Scope 3 emissions, which can be more difficult to quantify but are critical for SB 253 compliance.

2. Measure Financed Emissions

For companies involved in investments or lending, it’s crucial to track and measure financed emissions. Start collecting data from portfolio companies and borrowers, ensuring transparency and accuracy.

3. Create Public Disclosure Templates

Develop templates for public disclosure of emissions data that comply with the Greenhouse Gas Protocol standards. These templates should make it easier to report Scope 1, 2, and 3 emissions annually in line with the phased implementation of SB 253.

4. Implement Carbon Management Tools

Invest in tools or platforms that can automate and streamline emissions tracking and reporting. Carbon accounting platforms, like Arbor, can help with SB 253. These systems should be able to scale with your needs and ensure your data is transparent and traceable.

5. Engage with Third-Party Verifiers Early

Verification is a key part of SB 253 compliance, with third-party assurance starting with limited verification and moving toward reasonable assurance by 2030. Begin building relationships with accredited verifiers now to smooth the process later on.

6. Develop an Internal Compliance Team

Appoint a team responsible for ensuring your business is on track to meet SB 253’s requirements. This team should work cross-functionally, integrating carbon management into the financial, operations, and sustainability departments.
