New York City’s Climate Policy

New York City’s Climate Policy


Mayor Bloomberg set NYC on a sustainability course with his landmark PlaNYC in 2007. After he took office, Mayor de Blasio built on that work and released One City Built to Last in 2014, which outlined a plan to achieve the 80×50 goal. In November 2014, the City Council passed the 80×50 goal into local law.

In 2015, the Mayor released OneNYC, a plan founded on four pillars: economic growth, equity, sustainability, and resiliency. Taken together, these goals seek to build a sustainable city in the face of continuing climate change without sacrificing economic growth or leaving anyone behind.

Released the following year, Mayor de Blasio’s Roadmap to 80×50 outlined the steps that NYC must take to reduce GHG emissions 80% below 2005 levels by 2050. To identify challenges and determine how various sectors can work together to achieve this goal, NYLCVEF organized the Getting to 80×50 Policy Forum Series with the NYU Wagner School of Public Service. Each forum focused on a different sector that the Roadmap identified as a priority for transformation: transportation, buildings, energy, and waste. We also published detailed background papers on each sector.

In 2019, the Mayor released OneNYC 2050—a renewed and expanded version of the 2015 plan that commits the city to carbon neutrality, among other goals. Most sustainability and resiliency goals fall under “A Livable Climate,” one of the nine volumes of the plan, but some environmental goals are included in the other volumes.

Many of the indicators and initiatives established by the 2015 plan have moved to new categories in the 2019 plan or have disappeared completely. This lack of continuity has made it difficult to monitor the city’s progress and hold our elected officials accountable. Although the NYC Climate Action Tracker is designed as an oversight tool for goals from the 2015 plan, we have made every effort to indicate if these goals have changed or been removed in the 2019 plan.
