Local Law 154

New York City's Local Law 154, passed on December 15, 2021, establishes strict CO2 limits for new building construction, effectively requiring new buildings to be fully electric and free from fossil fuels by 2024 (for buildings less than 7 stories tall) and 2027 (for buildings more than 7 stories tall). This law makes New York City the largest city in the world to phase out fossil fuels from newly constructed buildings. Environmental groups, who campaigned for a "gas-free NYC," supported LL154 for several reasons, one being that removing gas stoves in residential units could improve indoor air quality. The bill outlines building electrification measures necessary to meet the new guidelines.
