fine per excess carbon ton
2030
stricter carbon cap limits
Local Law 97 places strict greenhouse gas emissions caps on New York City's largest structures to meet municipal 80x50 climate goals.
Covered Buildings
Emissions Limits
Financial Penalties
Applies to individual commercial and residential properties exceeding 25,000 gross square feet, or two or more buildings under the same tax lot exceeding 50,000 square feet.
Annual carbon caps are assigned based on occupancy classification. Thresholds step down significantly in 2030, impacting over 75 percent of covered properties.
Non-compliant owners face annual fines calculated at $268 per metric ton of CO2 equivalent exceeding their property's specific emissions cap.
Four Steps to Full Compliance
Emissions Audit
Capital Retrofits
Incentive Financing
Annual Reporting
Review LL84 benchmarking data to calculate current carbon intensity and model annual fine exposure through 2030.
Identify high-ROI energy conservation measures including heat pump conversion, modern controls, and building shell upgrades.
Leverage NYSERDA rebates, utility incentives, and low-cost C-PACE financing to offset upfront capital expenditures.
Submit certified emissions reports annually by May 1, verified by a registered Design Professional to avoid default penalties.
