Progressive cities and states have begun enacting policies to reduce greenhouse gas emissions from buildings, one of the leading sources of such emissions in the United States.

Electrification is currently a favored policy for decarbonizing buildings. This Article examines the potential for building electrification to impact tenant energy costs through a case study of New York City.
