The law enforces emissions regulations that require most buildings, particularly new york city's largest buildings, to meet advanced limits on greenhouse gas emissions by 2024 and increasingly tight emission limits by 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.
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.
