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 city’s climate action plan.
Owners must reduce greenhouse gas emissions by implementing energy efficiency upgrades, adopting clean energy systems, and enhancing building operations to align with compliance standards.
The compliance journey for owners is nuanced, as allowable emission limits vary according to building category and usage.
It demands meticulous building performance measures 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).
