Annual greenhouse gas emissions limits & civil penalties.

Statutory Civil Rate

$268.00 / tCO₂e

Fixed penalty per metric ton of excess carbon over cap.

Data Provenance

The Statutory Penalty Formula

NYC Administrative Code Title 28, Article 320 § 28-320.6

Statutory Equation

Annual Penalty ($) = $268 × [ Reported Emissions (tCO₂e) − (GFA × Cap ÷ 1,000) ]

$268 per Metric Ton: Mandatory civil penalty established by law and billed directly on property tax roll.

Occupancy Limit (Cap): DOB carbon emissions intensity cap (kgCO₂e/sq ft) determined by building occupancy group.

GFA ÷ 1,000: Converts gross floor area and emissions cap from kg into metric tons of allowable carbon.

Statutory Building Emissions Intensity Caps

The table below shows the Administrative Code occupancy-group limits (§ 28-320.3.1.2 / § 28-320.3.2) in kgCO₂e / sq ft / year.

Reporting uses a different table. Since DOB's rule 1 RCNY §103-14(c)(3), emissions limits are applied by ESPM property type, and the 2030–2034 factors are materially lower than the statutory figures below (e.g. Office 2.69 vs 4.53; Retail 2.10 vs 4.03; Laboratory 26.03 vs 11.93 kg/sf). For calendar years 2024 and 2025 an owner may use the occupancy-group limit only where it is greater than the ESPM factor. Every per-building figure in this app is calculated from the ESPM factor for that building's property type.
