New York State Department of Environmental Conservation (DEC) Commissioner Amanda Lefton announced the finalization of new regulations to implement mandatory greenhouse gas (GHG) emissions disclosure from carbon-intensive sectors, with reporting slated to begin in 2027.
The new reporting requirements come as the federal government under the Trump administration has pulled back on initiatives to provide transparency into corporate and industrial emissions, including plans to by the U.S. Environmental Protection Agency (EPA) end the Greenhouse Gas Reporting Program (GHGRP), and moves by the SEC to stop the implementation of its own new climate reporting rules. Several states, including New York and California have moved to implement climate disclosure requirements over the past several months.
Commissioner Lefton said:
“The Reporting Rule will enable DEC to collect the information necessary, despite proposed rollbacks on the federal level, and develop effective strategies that reduce harmful air pollution and direct investments where they are most needed.”
The finalization of DEC’s regulations follows a directive issued by New York Governor Kathy Hochul earlier this year to advance a Mandatory Greenhouse Gas Reporting Program, aimed at providing information on major polluters in the state, informing policies to reduce GHG emissions and to assess compliance with emissions reduction programs, and to help the state meet its emissions reduction goals.
Under the new regulation, facilities included in the new rules will be required to annually provide certain GHG emission data to DEC starting in June 2027, reflecting the previous year’s emissions. In addition, some large emission sources will also be required to verify their emissions data report annually using DEC-accredited third-party verification services.
Entities required to report under the new regulations include owners and operators of facilities in New York that emit 10,000 metric tons of CO2e annually, including electricity generation, stationary combustion, landfills, waste-to-energy, natural gas compressor stations, and other infrastructure; fuel suppliers including natural gas, liquid fuels, and petroleum products, liquefied natural gas and compressed natural gas, and coal; waste haulers and transporters with estimated emissions from solid wastes transported to landfills or combustion facilities outside of New York exceeding 10,000 MT CO2e in any year; electric power entities; agricultural lime and fertilizer suppliers, and anaerobic digestion and liquid storage of waste at facilities with waste imported to or generated at the facility generating 10,000 MT CO2 per year.
DEC issued draft regulations in March 2025, and received more than 3,000 public comments on the draft in its consultation. The finalized regulation included a few changes, including extending the verification reporting deadline for the first two years, and reducing reporting requirements from facilities that closed or ceased operations.
Lefton said:
“DEC’s greenhouse gas emissions reporting program and subsequent data collection is critical to the State’s ongoing efforts to protect our environment and improve the health and quality of life of all New Yorkers.”
