The State of California has been a trailblazer in adopting and passing new climate regulations. Just last year, the state signed two important bills into law – the Climate Corporate Data Accountability (SB 253) and the Climate-Related Financial Risk Act (SB 241). These bills are part of a climate accountability package, designed to enhance transparency and accountability regarding companies’ greenhouse gas emissions.

Now, a new bill has entered the ever-changing landscape – one that aims to reduce greenwashing and increase accountability. Bill AB 1305: The Voluntary Carbon Market Disclosures Business Regulation Act (VCMDA), was signed on October 2023 and as the name suggests, it is focused on those organizations participating in the carbon offsets market.

Effective January 2024, this bill applies to a range of California-operating organizations and entities that market or sell voluntary carbon offsets. It also applies to companies that make claims about achieving net zero emissions through carbon offsets. Now, these entities will be required to disclose detailed information on the status of their projects on their organization’s websites. Not disclosing this information on their websites can now result in fines up to $2,500 USD/day.

There are three key parts of the bill:

1. Marketing & Selling Carbon Offsets

For those organizations marketing or selling carbon offsets, they will now need to disclose details on their website, including (but not limited to):

• Project-based information – what specific protocols are used, locations for the project, associated timelines, start & end dates, trends over time (emission reductions/year and when will removals begin), type of projects, what standards it meets, third-party verifications completed, and more.
• Details on if the project was not completed or if the projected results & reductions were not met

2. Purchasing & Using Carbon Offsets

For those organizations purchasing or using voluntary carbon offsets and claiming that they achieve net zero emissions or are ‘carbon neutral’ because of them will need to include information including (but not limited to):

• The entity selling the offset
• Project name, type, and identification number
• Protocols used to estimate reductions
• Third-party verifications completed

3. Net Zero and Carbon Neutrality

For those organizations claiming to achieve net zero emissions or are ‘carbon neutral’, they will now need to include details on their website including (but not limited to):

• Documentation on how this ‘net zero’ or ‘carbon neutral’ claim is accurate or accomplished. Also, what third-party verification was done, and what methodologies were used.

New Amendments: SB 219 – Key Changes to Climate Regulations (September 2024)

On September 27, 2024, the California Legislature passed SB 219, introducing key amendments to climate accountability laws SB 253 and SB 261. These amendments provide some flexibility but retain the core requirements.

SB 253 Requirements:

• Regulation Development Deadline: Originally, CARB (California Air Resources Board) was required to develop regulations by January 1, 2025. This has now been extended to July 1, 2025. Although this delay impacts CARB’s timeline, entities must still prepare for the original reporting deadlines starting in 2026 for Scope 1 and 2 emissions.
• Scope 3 Reporting Flexibility: Companies will still need to report Scope 3 emissions starting in 2027, but CARB now has discretion to determine a new schedule, potentially extending the reporting window beyond 180 days after Scope 1 and 2 emissions are disclosed.
• Consolidated Reporting: Companies are now allowed to submit GHG reports, including Scope 1, 2, and 3 emissions, consolidated at the parent company level.
• Annual Filing Fee: The annual fee required for reporting is still applicable, but the payment date has become more flexible, no longer needing to coincide with the report filing.

SB 261 Requirements:

The biennial climate-related financial risk report must still be filed by January 1, 2026, without substantive changes. However, the annual filing fee is no longer tied to the report submission, giving companies flexibility on the payment date.

How to Prepare for Compliance with AB 1305, SB 253, and SB 261

It is important to remember what information regulations and frameworks require and how you can be proactive in meeting them. Oftentimes, organizations are reactionary to new legislation. Thus in order to properly organize their needs, organizations might see an increase in administrative work and time. However, if you have the necessary processes in place within your organization from the start, it will be easier to move forward with confidence. It also helps to know that you will already have access to accurate, verified, high-quality data captured within your organization.

Organizations should consider the following steps:

• Establish a robust data collection and management strategy, complete with audit trails and documentation to support. Centralizing all your emissions data in one place through a software tool can help manage version control. Additionally, it can assist in creating automation and mitigating risk.
• Leverage reporting tools and intuitive dashboards to understand emissions trends over time. Through this, make data-informed claims in external-facing materials. Clearly documented metrics can also support these claims.
• Seek guidance from trusted advisors and third-party consultants. This can help you get advice on how these new bills will impact your organization and what the best next steps are.
