Local Law 97 limits for this type
| Period | Factor (tCO2e/sf) | Buildings over the limit | Share | Median arithmetic exposure, those over | Sum |
|---|---|---|---|---|---|
| 2024-2029 | 0.01138 | 32 of 150 | 21.3% | $46,940/yr | $2,591,280/yr |

"Over the limit" = filed total location-based emissions above GFA x factor for the self-reported type; exposure = excess tCO2e x USD 268. Arithmetic on 2024 filings, not a prediction of what any owner pays: adjustments, Article 321, mixed-use splits, RECs and offsets are not modelled.
