The law enforces emissions regulations that require most buildings, particularly new york city's largest buildings, to comply with new ghg emissions limits by 2024 and even stricter targets by 2030.
To meet these goals, owners are required to initiate energy efficiency enhancements, shift to clean energy options, and streamline building systems for optimal performance.
The compliance journey for owners is nuanced, as allowable emission limits vary according to building category and usage.
Achieving compliance requires major performance upgrades, precise reporting, and alignment with regulatory and sustainability partners including DOB and NYSERDA.

Understanding the Urgency of Local Law 97 Compliance
New York City's ambitious climate targets reflect a critical drive to slash citywide greenhouse gas emissions.
Approximately 70% of all NYC emissions originate from buildings, putting them at the center of policy action.
By establishing emissions regulations through Local Law 97, the city has set forth unambiguous requirements for building owners in addressing urban climate change.
The firm understands that piecemeal upgrades aren’t enough for most buildings to comply with law 97.
Instead, an integrated approach combining historic preservation, energy efficiency retrofit, and clean energy adoption is essential to placing buildings on a sustainable trajectory.
The firm’s services address this, ensuring that owners meet not only compliance but also long-term resilience and financial performance through reduced energy costs and preserved asset value.
