The estimate is the taxable value times the class rate. It leaves out abatements, payment-in-lieu-of-taxes agreements and charges, so the actual bill can differ.

At its 2024 energy use, 99 Madison Avenue comes to about 319 metric tons of CO2e a year under Local Law 97's coefficients, against a limit of 910 tons for 2024 to 2029 (35% of the limit), so it would owe no penalty.

Estimated from the owner's 2024 Local Law 84 filing, which reports energy by source and floor area by use: Office 120,000 SF. It applies the coefficients and per-use limits in Department of Buildings rule 1 RCNY 103-14 and Administrative Code 28-320.3.1.1 (as the Department lists them) and the $268 per ton penalty, checked 2026-10-04. It is not the building's Local Law 97 report: that report can count renewable energy credits, solar and storage deductions and, for 2024 and 2025, the law's occupancy group limits where higher, and penalties can be reduced for good faith efforts.
