New York City’s one million buildings account for nearly two-thirds of the city’s carbon emissions. The Climate Mobilization Act of 2019 included Local Law 97 (LL97), which sets increasingly stringent caps on greenhouse gas emissions from the city’s largest buildings starting in 2024. Most buildings over 25,000 square feet will be subject to LL97, and buildings that exceed their annual emissions limits will face financial penalties.
