As New York City continues to lead the charge in sustainability, Local Law 97 (LL97) stands out as a pioneering regulation to significantly reduce greenhouse gas emissions in the built environment. This ambitious initiative requires property owners and managers to comply with strict emissions limits under the City’s Climate Mobilization Act.

With the first phase of compliance set for 2024 and further requirements emerging in 2026, building owners and managers must take proactive steps to ensure compliance. Here’s your essential checklist to navigate the complexities of LL97 and uphold your commitment to a greener future.

Key Dates and Deadlines

  • The annual LL97 compliance report for the 2025 calendar year is due May 1, 2026. This report must be certified by a registered design professional and submitted through the NYC Department of Buildings (DOB).
  • By 2026, the grace periods for initial compliance will have ended, and enforcement for the first cycle of penalties (for the 2024 compliance year) will be in effect. Fines can be significant, including penalties for late filing ($0.50 per square foot per month) and for exceeding emissions limits ($268 per metric ton of CO₂e over the cap).
  • 2025-2029 – the LL97 First Compliance Period – Initial Carbon Limits Apply
  • 2030-2034 – the LL97 Second Compliance Period – Stricter 40% Reduction Limits
  • 2050 – the Carbon Neutrality Target – 80% Reduction Required
