The 4th assessment of the New York City Panel on Climate Change (NPCC4) continues the long-term work of the previous three panels, providing insight into the state of the science on climate change and the implications for adaptation and mitigation policy in New York City.

Building on the longitudinal data afforded by this ongoing research, this assessment centers equity as a shared focus across all working groups. This is achieved through inclusive internal processes for working group activities and explicit attention to uneven impacts and vulnerabilities associated with climate change policy responses.

NPCC4 updates the work of previous panels on the topics of Climate Science, Equity, and Flooding and provides new work on topics that were not covered by previous panels: Futures and Transitions and Energy and Energy Insecurity. Health, which has not been addressed since 2015, is also addressed in NPCC4.
