Decarbonization: Local Law 97 Impact

Local Law 97 (LL97), part of Mayor de Blasio’s New York City Green New Deal and included in the Climate Mobilization Act, outlines one of the nation’s most ambitious plans to eliminate GHG emissions. As buildings account for two-thirds of GHG emissions in New York City1, building owners will play a significant role in reaching carbon neutrality through compliance of new energy efficiency and greenhouse gas (GHG) emissions limits.

Local Law 97: What is it and who does it impact?

Local Law 97 (LL97), part of Mayor de Blasio’s New York City Green New Deal and included in the Climate Mobilization Act, outlines one of the nation’s most ambitious plans to eliminate GHG emissions. As buildings account for two-thirds of GHG emissions in New York City1, building owners will play a significant role in reaching carbon neutrality through compliance of new energy efficiency and greenhouse gas (GHG) emissions limits.

Download LL97 Factsheet
Download NY Policy & Incentive Highlights

Local Law 97, which will require the annual monitoring of buildings’ energy and water usage, includes*:

  • Buildings that exceed 25,000 gross square feet.
  • Two or more buildings on the same tax lot that together exceed 50,000 square feet.
  • Two or more buildings owned by a condo association governed by the same board of managers and that exceed 50,000 square feet together.1 

* Some buildings are exempt from Local Law 97. More information can be found on the Department of Buildings (DOB) Greenhouse Gas Emission Reporting website. 

When will Local Law 97 be implemented?

  • 2024: LL97 Benchmarking Begins

    Annual GHG emissions reporting commences on May 1, 2025, for the calendar year 2024, then on May 1 annually thereafter as required by the Department of Buildings. Non-compliance with reporting results in fines starting in 2025.

  • 2025: Initial Fines are Assessed

    Limits based on Energy Star Portfolio Manager (ESPM) property types takes effect. These new efficiency and GHG emission limits affect different properties starting in 2024, with specific limits for 2024 – 2029 available for review.

  • 2026: ESPM Property Types Required

    For 2024 and 2025, owners with stricter emissions limits can choose between the original New York City Building Code occupancy group limits or ESPM property type limits. Starting in 2026, emissions must be reported using ESPM property types exclusively.

  • 2030: Emission Limits by Property Type Lowered

    Emission limits per square foot (tCO2e) for buildings are lowered, necessitating GHG reductions under 1 RCNY §103-14, using ESPM property types. The milestone is a 40% GHG reduction goal.

  • 2035: Emission Factors Requirements Lowered

    Emission factors are adjusted again, further reducing GHG emissions per square foot (tCO2e) as per 1 RCNY §103-14, utilizing ESPM property types.

  • 2050: Carbon Neutrality Reached

    Required citywide emissions reporting aims for full carbon neutrality by 2050.


How do I ensure my building(s) comply with the Local Law 97 codes and laws?

Understanding and navigating the new limits introduced by Local Law 97 (LL97) can be overwhelming and stressful for building owners. Each journey toward compliance may look different but rest assured, the right collaborator will meet you at any point. The path to compliance can be summed up in one word—decarbonization. The journey to decarbonize your building is uniquely yours and Trane® is the right collaborator to help guide you.

Are there any notable exemptions or incentives?

Good Faith Exemptions 

Provided an owner has already completed a.) benchmarking, b.) lighting upgrades and submetering requirements, and, c.) has submitted a Local Law 97 annual emissions report, a building can qualify for good faith exemptions from the Department of Buildings by meeting certain requirements by May 1, 2025. 

Article 321 Buildings

Provided an owner has already completed a.) benchmarking, b.) lighting upgrades and submetering requirements, and, c.) has submitted a Local Law 97 annual emissions report, a building can qualify for good faith exemptions from the Department of Buildings by meeting certain requirements by May 1, 2025. 

Beneficial Electrification Credits 

Beneficial electrification credits are available for properties that install electric heating, cooling and/or hot water equipment that meets specified minimum energy requirements. Credits will apply to equipment installed before 2030, though there are added incentives for owners who install qualifying electrical equipment before 2027.
