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 even stricter targets by 2030.
Owners must reduce greenhouse gas emissions by introducing energy-saving technologies, adopting clean energy systems, and upgrading building infrastructures to meet these targets.
The compliance journey for owners is nuanced, as allowable emission limits vary according to building category and usage.
It demands diligent energy performance upgrades combined with detailed reporting and coordination with agencies like the New York City Department of Buildings (DOB) and key sustainability programs such as NYSERDA (New York State Energy Research and Development Authority).
