Methodology

Exposure analysis runs on NYC’s public LL84 benchmarking dataset (latest reporting year per building) and PLUTO tax-lot records. Cap math uses the published 6.75 kgCO₂e/sf (2024–2029) and 4.07 kgCO₂e/sf (2030–2034) multifamily caps with the $268/mt CO₂e penalty rate. Real-world penalties may differ based on REC/offset purchases, Article 321 affordable-housing adjustments, and future DOB rule-making. This is exposure analysis, not a penalty prediction. The point is to surface whether each building is well-positioned, facing the 2030 cliff, or already in material exposure — and to put that read in the context an underwriter would use.
