Intro
In a significant shift toward corporate environmental accountability, several U.S. states are advancing legislation requiring large businesses to disclose their greenhouse gas emissions. New York, New Jersey, Colorado, and Illinois have introduced bills that would mandate comprehensive climate data reporting for companies with annual revenues exceeding $1 billion.
These initiatives signal a growing trend of state-level climate action that will reshape corporate reporting obligations nationwide.
Main
New York's Climate Corporate Data Accountability Act
New York lawmakers have introduced companion bills (A04282 and S03456) that would require businesses with revenues over $1 billion operating in the state to disclose their carbon footprint. Key provisions include:
Implementation Timeline: Reporting entities would first disclose scope 1 and 2 emissions data in 2027, followed by scope 3 emissions in 2028
Enforcement Mechanism: The New York Attorney General can bring civil actions against non-compliant entities
Potential Penalties: Up to $100,000 per day for willful violations, with a cap of $500,000 per reporting year
Similarity Note: The legislation mirrors California's Climate Corporate Data Accountability Act
Main
New Jersey Follows Suit
New Jersey's S4117, also titled the "Climate Corporate Data Accountability Act," follows a similar framework:
Scope: Applies to entities with annual revenue exceeding $1 billion doing business in New Jersey
Disclosure Requirements: Companies must report scope 1, 2, and 3 greenhouse gas emissions
Verification: Third-party assurance or verification will be required
Main
Colorado's Emissions Transparency Push
Colorado has introduced HB25-1119, which would:
Begin Reporting: Scope 1 and 2 emissions disclosure starting January 1, 2028
Expand Requirements: Scope 3 emissions reporting beginning January 1, 2029, with additional specified sources by 2031
Set Standards: Requires calculation using the Greenhouse Gas Protocol Corporate Accounting and Reporting Standard
Establish Penalties: Civil penalties up to $100,000 for each day of non-compliance
Empower Regulators: The Colorado Air Quality Control Commission would have authority to implement and adjust reporting deadlines
Main
Illinois Considers Accelerated Timeline
Illinois's Climate Corporate Accountability Act (HB4268) proposes the most aggressive implementation schedule:
Rapid Deployment: If passed, reporting would begin January 1, 2025, for the 2024 calendar year
Digital Platform: Requires the Secretary of State to develop a publicly accessible emissions registry by January 2025
Verification Requirements: Disclosures would need independent verification by an approved third-party auditor
Current Status: The bill has been referred to the Illinois House Rules Committee with consideration expected after the legislative recess ends in November 2024
Main
What This Means for Businesses
These state initiatives represent a significant shift in climate disclosure requirements across the United States. Companies operating in multiple states will soon face a complex patchwork of reporting obligations with potentially substantial penalties for non-compliance.
Organizations with revenues exceeding the $1 billion threshold should:
Begin developing robust emissions tracking systems
Prepare for third-party verification processes
Monitor legislative developments across states where they conduct business
Consider adopting standardized reporting frameworks aligned with the Greenhouse Gas Protocol
WRAPPING UP
OUR TAKE: As more states advance climate disclosure legislation, companies that proactively develop comprehensive emissions reporting capabilities will be better positioned to navigate this evolving regulatory landscape. The trend toward mandatory climate disclosures shows no signs of slowing, making early preparation a strategic imperative for forward-thinking organizations.
