Local Law 97 mandates that covered buildings 25,000 square feet and larger cannot emit greenhouse gas (GHG) emissions at levels higher than the limits set by the law. These carbon limits are set based on the occupancy group of the building and take effect in 2024.
Beginning May 1st 2025, covered buildings will need to submit a report showing their carbon emissions from the year prior (2024). This reporting of a building’s emissions must occur annually and the report must be prepared by a registered design professional.
Buildings that do not submit an annual report prior to May 1st or release carbon emissions above their occupancy group limit will be fined.
