Most buildings must reach new ghg emissions limits by 2024 under this law, with decreasing allowable emissions thresholds arriving in 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.
Owners must deliver robust energy upgrades and maintain strict reporting, all while working closely with the DOB and participating in NYSERDA-led sustainability efforts.
