As we approach the close of 2025, one key takeaway is that this year has been an especially active one for climate litigation in New York. On October 24, 2025, the New York Supreme Court granted the petition in Citizen Action of New York et al. v. New York State Dept. of Environmental Conservation (No. 903160-25), and directed the New York State Department of Environmental Conservation (NYSDEC) to promulgate regulations implementing the Climate Leadership and Community Protection Act (CLCPA). In addition, New York courts in 2025 have so far upheld several of New York State and New York City's landmark climate laws related to the built environment, allowing for the full implementation and enforcement of building energy efficiency and decarbonization requirements.
