On December 1, 2025, the Department of Environmental Conservation (DEC) announced that it finalized regulations establishing a Mandatory Greenhouse Gas Reporting Program.

Mandatory Greenhouse Gas Reporting Program Background

As part of her 2025 State of the State address, Gov. Hochul directed the New York State Energy Research and Development Authority (NYSERDA) and DEC to "take steps forward on developing the cap-and-invest program, proposing new reporting regulations to gather information on emissions sources, while creating more space and time for public transparency and a robust investment planning process." Pursuant to this directive, on March 26, 2025, DEC proposed draft GHG reporting regulations under 6 NYCRR Part 253. The final regulations, issued on December 1, 2025, will become effective 30 days after filing the Notice of Adoption with the Department of State.
