Making New York City's One Million Buildings Clean and Efficient

In most major cities in the US, transportation produces the bulk of emissions. In New York City, 68% of emissions come from buildings. Almost half of those emissions come from only 2% of buildings. To counter this, the city needs aggressive retrofits to make existing buildings more efficient.

Mayor's Office works on a range of programs to improve the energy efficiency of buildings throughout New York City. This includes establishing public buildings as models of sustainability, strengthening requirements for new construction and renovation, and ensuring that benefits are equally shared throughout New York City. Our green building initiatives aim to make homes more affordable, improve air quality, and create a thriving market with new jobs and new businesses.
