What We Do

The City and County of Honolulu Office of Climate Change, Sustainability and Resiliency was established by City Charter in 2016 with overwhelming approval by O‘ahu voters. As mandated by Charter, the Office is tasked with tracking climate change science and potential impacts on City facilities, coordinating actions and policies of departments within the City to increase community preparedness, developing resilient infrastructure in response to the effects from climate change, and integrating sustainable and environmental values into City plans, programs, and policies. As a member of the Rockefeller Foundation’s 100 Resilient Cities network, the Office is also responsible for developing Oʻahu’s Resilience Strategy, which will include the City’s first-ever climate action and adaptation plan.


Climate change is the most important issue of our era, and we need local government leadership now more than ever. We in Hawai‘i stand with the over 190 countries who have come together to reduce greenhouse gas emissions. At the City and County of Honolulu we are committed to a more resilient future where we not only survive, but adapt and grow in the face of change and uncertainty.
— Kirk Caldwell, Mayor

In addition, the Office is responsible for providing administrative support to the Climate Change Commission, which consists of five members with expertise in climate change in Hawai‘i. The Commission advises the Office with the latest science and information on climate change effects in and provides advice to the Office, the Mayor, City Council, and executive departments of the City.
