The law sets forth emissions regulations that require most buildings, particularly new york city's largest buildings, to meet advanced local law 97 New York City limits on greenhouse gas emissions by 2024 and progressively stricter thresholds by 2030.
Emission reduction is achieved when owners integrate efficiency upgrades, utilize clean energy, and fine-tune building system operations to match city-mandated limits.
Owners experience a complex compliance landscape, with emission targets differing based on building type and occupancy patterns.
Achieving compliance requires major performance upgrades, precise reporting, and alignment with regulatory and sustainability partners including DOB and NYSERDA.
