New Your City's Local Law 97

Groundbreaking climate legislation sets carbon emissions caps for energy use in NYC’s large buildings starting in 2024.


Don't panic! There's an upside. The measures we find to help you comply with NYC's Local Law 97 will help you permanently reduce operating and maintenance costs, in addition to other financial benefits. The savings we find will also help pay back the installation costs over time. Even better, we can finance and manage the entire project for you with $0.00 out-of-pocket expense. As we said, don't panic. Click the link below. Let's discuss your property and help you start saving money and comply with the City of New York before they begin imposing violations and fines.


  • Affects buildings greater than 25,000 square feet
  • Sets increasingly stringent limits on carbon emissions per square foot in 2024 and 2030
  • Flexibility to comply through renewable energy credits and/or emissions offsets
  • Allows some affordable housing to choose low-cost energy-saving measures instead of emissions limits
  • New Office of Building Energy and Emissions Performance at the Department of Buildings
  • Strong advisory board to help refine emissions metrics and limits
  • Carbon trading study and implementation plan
  • Penalties for non-compliance and variances for financial hardship


  • Covers ~50,000 buildings and nearly 60 percent of the
    city’s building area: 59 percent residential and 41 percent
  • Requires 40 percent citywide emissions reductions by 2030 from a 2005 baseline.
  • For covered buildings, that’s a 26 percent carbon cut (5.3 million metric tons) from today, the equivalent of San Francisco’s citywide emissions.
  • Many buildings are significantly above emissions limits and will require comprehensive retrofits or alternate compliance by 2030.


  • The maximum annual penalty is the difference between a building’s annual emissions limit and its actual emissions multiplied by $268.
  • First compliance report due May 1, 2025 (and every May thereafter).


  • Limits from 2024-2029 will affect the most carbon-intensive 20 percent of buildings.
  • Limits from 2030-2034 are set to affect the most carbon-intensive 75 percent of buildings, with 25 percent under the cap, if based on current Portfolio Manager emissions factors for energy sources (actual impact depends on emissions factors specified in rules no later than Jan. 1, 2023).

How are building emissions limits determined?

  • The law sets emissions intensity limits (metric tons of CO2e per square foot) for 10 building categories based on Building Code occupancy groups.
  • A building’s annual emissions limit equals its emissions intensity limit multiplied by its gross floor area.
  • Flexibility for future rulemaking to include more building categories from EPA’s Portfolio Manager and a different but equally stringent metric for 2030.
  • Very wide distribution in the emissions intensity of covered buildings means significant variation in carbon reduction requirements.


  • Up to 100 percent deduction from annual emissions for purchase of credits for renewable energy in NYC or sinking directly into NYC.
  • Deductions for purchase of greenhouse gas offsets (up to 10 percent of limit) and peak energy storage.
  • Potential adjustments for buildings more than 40 percent over the 2024-2029 limits based on density or other factors.
  • The city will study and develop an implementation plan for carbon trading by Jan. 1, 2021.


  • Earlier timeline for NYC government buildings: 40 percent emissions reductions by 2025 and 50 percent
    by 2030.
  • Rent-regulated buildings, houses of worship, and some subsidized housing must implement prescriptive energy-saving measures or meet the 2024 cap.
  • Adjustment is available for hospitals and healthcare facilities to a percent reduction framework.
