New York State, December 17, 2025

New York State has finalized regulations mandating that businesses emitting 10,000 metric tons or more of CO₂ equivalent annually must report their greenhouse gas emissions starting in 2027. This initiative is aimed at enhancing transparency and fulfilling the state’s climate objectives. With a requirement for third-party verification for larger sources, businesses are advised to prepare monitoring systems for compliance. This move aligns with the state’s commitment to sustainability goals and federal reporting standards.

New York Finalizes Greenhouse Gas Reporting Regulations for Businesses

New York State has finalized regulations requiring certain businesses to report their greenhouse gas (GHG) emissions annually, starting in 2027. This initiative aims to enhance transparency and support the state’s climate goals.

Key Details of the Reporting Program

• Reporting Entities: Businesses emitting 10,000 metric tons or more of CO₂ equivalent per year, including power plants, landfills, fuel suppliers, industrial facilities, and waste-to-energy facilities.
• Reporting Deadline: Emissions data for 2026 must be submitted by June 1, 2027.
• Verification Requirements: Larger emission sources will need annual verification by DEC-accredited third parties.

Purpose and Implementation

The New York State Department of Environmental Conservation (DEC) developed this program to collect comprehensive GHG emissions data, informing policies to reduce emissions and assess compliance with reduction programs. The program is part of the state’s efforts to meet the 2019 Climate Leadership and Community Protection Act (CLCPA) goals. The finalized regulation includes adjustments such as extending the verification reporting deadline for the first two years and aligning certain terms with federal reporting requirements.

Background Context

In 2025, Governor Kathy Hochul directed the DEC to establish a mandatory GHG Reporting Program to support the state’s climate objectives. The program requires businesses emitting significant GHGs to report their emissions annually, starting in 2027. This initiative reflects New York’s commitment to environmental sustainability and aligns with federal reporting standards to ensure consistency and accuracy in emissions data.

Implications for Affected Businesses

Businesses subject to these regulations will need to implement systems for monitoring and reporting their GHG emissions. The requirement for third-party verification aims to ensure the accuracy and reliability of the reported data. While the program focuses on data collection, it lays the groundwork for future policies aimed at reducing GHG emissions and promoting a cleaner energy economy in New York State.

Next Steps for Compliance

Businesses that meet the reporting thresholds should prepare by establishing monitoring systems and familiarizing themselves with the reporting requirements. The DEC is developing an online reporting tool to streamline the submission process. Entities are encouraged to stay informed about updates and participate in any training sessions offered by the DEC to ensure compliance with the new regulations.

Conclusion

The finalization of New York’s GHG reporting regulations marks a significant step toward greater environmental accountability and transparency. Affected businesses should begin preparations to meet the reporting requirements, contributing to the state’s broader efforts to combat climate change and promote sustainable practices.
