In a pivotal decision on May 22, 2025, the New York State Court of Appeals affirmed the legality of New York City’s Local Law 97 (LL97), effectively ending a prolonged legal challenge and reinforcing the city’s authority to mandate greenhouse gas emissions reductions for large buildings. This ruling not only solidifies LL97’s role in the city’s climate strategy but also underscores the urgency for building owners to pursue compliance solutions.
LL97, enacted in 2019 as part of the Climate Mobilization Act, requires buildings over 25,000 square feet to meet stringent emissions caps, aiming for a 40% reduction by 2030 and 80% by 2050 compared to 2005 levels. The law’s enforcement began in 2024, with the first compliance reports due by May 1, 2025, and penalties for non-compliance reaching up to $268 per metric ton of CO₂ emissions over the limit.
The recent court decision in Glen Oaks Village Owners, Inc. v. City of New York concluded that LL97 is not preempted by the state’s Climate Leadership and Community Protection Act (CLCPA). The Court emphasized that the CLCPA does not occupy the field of greenhouse gas regulation, allowing local laws like LL97 to operate concurrently. This affirmation removes legal uncertainties and compels building owners to take definitive action toward compliance.
