Recognizing the existential threat that climate change poses to New York City and the world, OneNYC:2050 sets our city on the path to achieve carbon neutrality by 2050. Because the energy used in New York City's buildings represents 68% of citywide greenhouse gas (GHG) emissions, improving the energy efficiency of the city's existing building stock represents the greatest opportunity to reduce citywide GHG emissions.
In order to achieve our ambitious goals, NYC has enacted legislation to significantly cut pollution and emissions from buildings.
The Climate Mobilization Act, enacted in 2019, is the largest climate solution put forth by any city in the world. It consists of a slate of climate laws designed to dramatically cut carbon in New York City.

The New York City Energy Conservation Code (NYCECC) is comprised of New York City local laws and the current Energy Conservation Construction Code of New York State (ECCCNYS). By State law, all local government energy codes, including the NYCECC, must be more stringent than the ECCCNYS.
The updated NYCEEC went into effect on May 12, 2020.

In New York City, almost two thirds of heat-trapping pollution comes from buildings. The Greener, Greater Buildings Plan set the critical groundwork for subsequent climate legislation around building energy efficiency, energy and water consumption, and more.
