NYC Resources 311 Office of the Mayor

The Mayor's Office of Sustainability and the Mayor's Office of Recovery and Resiliency oversee and implement the sustainability and resiliency initiatives in One New York: The Plan for a Strong and Just City. Together with our collaborators – the agencies, organizations, and New Yorkers who make our work a reality – we have made significant progress in just a few years:

  • The cleanest air in 50 years
  • 950,000 trees and six million square feet of reflective rooftop added to our urban landscape
  • Building codes upgraded to prepare for floods, wind, and extreme weather
  • 19% reduction in carbon emissions since 2005, on track to reaching an 80% reduction by 2050

A changing climate, a growing population, aging infrastructure, and an evolving economy with increasing inequality pose challenges to our city’s success and quality of life. Recognizing that we determine New York's future by how we shape our response to these challenges, Our work includes actions to mitigate climate change while also preparing for the risks it presents, ensuring quality of life for generations of New Yorkers to come.
