Local Law 97's timeline mandates that building owners begin emissions reduction efforts in 2024 and continue to lower them by 2030, as part of the overarching sustainability agenda.
To meet these goals, owners are required to initiate energy efficiency enhancements, shift to clean energy options, and streamline building systems for optimal performance.
Owners experience a complex compliance landscape, with emission targets differing based on building type and occupancy patterns.
It demands diligent energy performance upgrades combined with rigorous reporting and coordination with agencies like the New York City Department of Buildings (DOB) and key sustainability programs such as NYSERDA (New York State Energy Research and Development Authority).
