OneNYC 2050: Building a Strong and Fair City is New York City’s long-term strategic plan, issued by the Mayor’s Office of Climate & Environmental Justice. The report is associated with the City of New York and was published in April 2019. It presents a citywide framework linking climate action, social equity, public health, housing, transportation, resilience, and economic opportunity. The document is framed as a policy plan for New York City, New York, and reflects the priorities of the administration led by Mayor Bill de Blasio at the time.
The report’s core argument is that climate policy and social policy should be treated together. It sets out goals for reducing greenhouse gas emissions, preparing infrastructure for climate risks, improving air quality, expanding access to affordable housing, supporting public transit and cycling, and addressing inequities in access to services and environmental quality. The plan also connects these objectives to broader ambitions such as a fairer economy and healthier neighborhoods.
Methodologically, OneNYC 2050 is a strategic policy document rather than a research study. Its findings are presented through planning targets, policy commitments, and sector-specific actions, drawing on city data, prior planning work, and existing municipal programs. The report organizes its material around practical action areas rather than a formal empirical method, and it is designed to guide implementation across city agencies.
The resource is useful as a snapshot of how New York City linked climate governance with equity planning in the late 2010s. It is also important as an example of municipal strategy written for public accountability, policy coordination, and long-term urban planning.
