New York became the largest city in the United States to require green roofs when the City Council passed wide-ranging legislation called The Climate Mobilization Act to cool the city, mitigate the effects of storms, and achieve carbon neutrality by 2050.

The Climate Mobilization Act

The Climate Mobilization Act, passed April 18, 2019, is the largest single act to cut climate pollution by any city in the world. CMA is a package of bills and resolutions that require new construction and existing buildings undergoing renovations to integrate green roofs, small wind turbines, and/or solar panels.


Access to Green Roof Information

Local Law 93 creates an office of alternative energy, which is required to provide a website of information and resources for the installation of green roofs.


Green Roofs for New ConstructionLocal Laws 92 & 94 – Green Roofs & Solar PV is new NYC legislation requiring that the roofs of certain buildings be covered in green roofs or solar photovoltaic electricity-generating systems. This bulletin clarifies the green roof and solar requirements for new and existing buildings under Local Laws 92 and 94 of 2019. 

Green Roof Tax Abatement Increase

Resolution 66 triples the existing tax break for property owners who install green roofs in high-priority areas, increasing the abatement from $5.23/sqft to $15/sqft of green space through 2024.
