Local Law 97

Part of the Climate Mobilization Act of 2019, Local Law 97 is an ambitious plan to drive down greenhouse gas (GHG) emissions in NYC’s larger buildings. With few exceptions, all buildings over 25,000 square feet – around 60% of the City’s building area – are covered under the law.   

At the heart of Local Law 97 are emissions limits for properties based on their Energy Star Portfolio Manager (ESPM) property type. Buildings that do not reduce their emissions below the established limits are subject to fines of $268 per ton of CO2 over the limit.

The emission limits go into effect starting on January 1st, 2024, with the first compliance report due in May of 2025. Further emission limits are then scheduled for 2030, 2035, 2040, and 2050, at which point all covered buildings must have net-zero emissions.

As a property owner, it is your responsibility to ensure that any covered building you own is in compliance with the law. Review the resources below to check your compliance status and get assistance if needed.
