New York City Enacts GHG Limits for Residential and Commercial Buildings
On April 22, 2019, the New York City Council celebrated Earth Day by enacting the Climate Mobilization Act into law. The centerpiece of this important legislative package is Introduction 1253-2018 (Intro 1253). This local law will impose binding limits on the emission of greenhouse gases (GHGs) from major buildings in New York City, beginning in calendar year 2024. Although the law includes important exceptions and the opportunity for “adjustments” to its generic emission limits, the law is clearly one of the most ambitious actions yet taken by a municipality to curb GHG emissions from existing buildings.
