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.
Owners must reduce greenhouse gas emissions by introducing energy-saving technologies, transitioning to clean energy sources, and upgrading building infrastructures to satisfy city requirements.
The compliance journey for owners is nuanced, as allowable emission limits vary according to building category and usage.
Owners must deliver robust energy upgrades and maintain strict reporting, all while working closely with the DOB and participating in NYSERDA-led sustainability efforts.
