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.
Emission reduction is achieved when owners integrate efficiency upgrades, utilize clean energy, and fine-tune building system operations to match city-mandated limits.
For building owners, the path to compliance is complex, with variable emissions limits depending on building type and occupancy.
Owners must deliver robust energy upgrades and maintain strict reporting, all while working closely with the DOB and participating in NYSERDA-led sustainability efforts.
