The law enforces emissions regulations that require most buildings, particularly new york city's largest buildings, to comply with new ghg emissions limits by 2024 and progressively stricter thresholds by 2030.
Owners must reduce greenhouse gas emissions by carrying out energy efficiency improvements, adopting clean energy systems, and upgrading building infrastructures to align with compliance standards.
Owners experience a complex compliance landscape, with emission targets differing based on building type and occupancy patterns.
It demands meticulous building performance measures combined with rigorous 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).
