Originally released in 2007 under the name “PlaNYC,” One New York: The Plan for a Strong and Just City (OneNYC) is a groundbreaking effort to address New York City’s long-term challenges: the forecast of 9 million residents by 2040, changing climate conditions, an evolving economy, and aging infrastructure.

OneNYC envisions how the physical city should be shaped to address a range of social, economic, and environmental issues while building on New York City’s strengths. It draws upon best practices when appropriate, but also proposes innovative solutions for our most vexing challenges. The plan calls on regional partners to join us on our path to the fifth century, and sets goals and targets that are both aspirational and achievable, encompassing both short-term actions and ambitious plans for the future.

Under Local Law 84 (2013), a long-term plan considering population projections, housing, air quality, coastal protections, and other sustainability and resiliency factors is required every four years on Earth Day. OneNYC represents a unified vision for a sustainable, resilient, and equitable city, and charts the path for collectively achieving this goal. This plan was developed with cross-cutting interagency collaboration, public engagement, and consultation with leading experts in their respective fields. The Mayor’s Office of Sustainability oversees the development of OneNYC and now shares responsibility with the Mayor’s Office of Recovery and Resiliency for ensuring its implementation.
