The law enforces emissions regulations that require most buildings, particularly new york city's largest buildings, to reduce greenhouse gas emissions below defined thresholds by 2024 and even stricter targets 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.
The compliance journey for owners is nuanced, as allowable emission limits vary according to building category and usage.
Achieving compliance requires major performance upgrades, precise reporting, and alignment with regulatory and sustainability partners including DOB and NYSERDA.
