Local Law 97 - What it does?

New York City’s Local Law 97 (LL97) sets annual greenhouse gas (GHG) emissions limits for most large buildings starting with the 2024 calendar year, with much stricter limits beginning in 2030 and continuing toward a 2050 carbon neutral goal. Covered buildings that exceed these limits face annual penalties of $268 per metric ton of CO₂e over their cap, plus separate fines for late or inaccurate reporting.
