O‘ahu agenda setting workshop

On June 8, 2017, the Resilient O‘ahu Workshop introduced 100RC to a diverse group of 140 city stakeholders drawn from 19 sectors and representing 117 unique organizations. They shared knowledge and produced initial recommendations to help inform a Resilience Strategy.

At the Workshop's City Resilience Diagnostic exercise, O‘ahu's top strengths and weaknesses were identified.

sunset beach Erosion Presentation

Following unprecedented erosion at Sunset Beach Park on Oʻahu’s North Shore in the winter of 2017, the City and County of Honolulu took several steps to mitigate further immediate erosion and address public safety concerns posed by damaged or endangered facilities. This presentation outlines those actions taken, and explores the options and scenarios moving forward.

Hawai‘i Sea Level Rise Vulnerability & Adaptation Report

The Hawai‘i Climate Change Mitigation & Adaptation Commission (Climate Commission) has accepted its first major report since its formation in fall 2017. The Sea Level Rise Vulnerability & Adaptation Report is a comprehensive 304-page-long description of where Hawai‘i is today and where we will be in the future as sea level rise (SLR) increases with global warming.

The report, developed under the leadership of the DLNR Office of Conservation and Coastal Lands (OCCL), was initially mandated by Act 83 in 2014 and was expanded by Act 32 in 2017 and provides the first state-wide assessment of Hawai‘i’s vulnerability to sea level rise.  It includes recommendations to reduce exposure to sea level rise along with recommendations to increase our capacity to adapt. 

On December 4-6, 2017, Chicago Mayor Rahm Emanuel held the North American Climate Summit in concert with the Global Covenant of Mayors for Climate and Energy partners, bringing together leaders from the U.S., Canada and Mexico to sign the Chicago Climate Charter and commit to addressing climate change at the local level.

Mayors gathered for the Summit were invited to make commitments to move forward with significant emissions reductions regardless of action taken by their respective federal governments. Working together, we harnessed existing climate goals and created a regional roadmap for climate leadership.

NCS National Citizen Survey 2017.PNG

National Citizen Survey

The ninth NCS captures residents’ opinions within the three pillars of a community--Community Characteristics, Governance and Participation, and across eight facets of community--Safety, Mobility, Natural Environment, Built Environment, Economy, Recreation and Wellness, Education and Enrichment, and Community Engagement. The citizen survey is comprised of four reports: Community Livability, Dashboard Summary of Findings, Trends over Time, and Technical Appendices. 

Hawai‘i green growth aloha+ challenge

Hawai'i launched the Aloha+ Challenge, a statewide commitment to sustainability, with the leadership of the Governor, four county Mayors, Office of Hawaiian Affairs, State Legislature, and Hawai‘i Green Growth public-private partners across the state. The Aloha+ Challenge: He Nohona ‘Ae‘oia, A Culture of Sustainability builds on Hawai‘i's history of systems thinking, indigenous knowledge, and successful track record on sustainability to identify six ambitious goals to be achieved by 2030 in clean energy transformation, local food production, natural resource management, solid waste reduction, smart sustainable communities, and green workforce and education.


Climate Mayors Map

Leaders from the City and County of Honolulu, Hawaiʻi County, Maui County, and Kauaʻi County have joined 233 mayors, from 46 US states and territories, representing over 51 million Americans to oppose the Trump Administration’s proposed repeal of the Clean Power Plan (CPP). 

Honolulu Mayor Kirk Caldwell, Hawaiʻi County Mayor Harry Kim, Maui County Mayor Alan Arakawa, and Kauaʻi County Mayor Bernard P. Carvalho Jr. all signed onto a letter in opposition to the Environmental Protection Agency’s proposed Repeal of Carbon Pollution Emission Guidelines for Existing Stationary Sources: Electric Utility Generating Units.

Signing the letter signals Hawaiʻi’s continued commitment to transition away from dependence on fossil fuels and reinforces a 2015 state law that requires 100 percent of Hawaiʻi’s electricity to be generated by renewable sources by 2045. Hawaiʻi’s 2045 goal was the nation’s first such benchmark.

Hawaiʻi is the only state that entirely supports the Climate Mayors network through its four mayors’ participation. In signing this letter opposing repeal of the CPP, they are joined by other members of the Climate Mayor’s network (, which includes Los Angeles, Houston, Portland, New York, and Puerto Rico.

The actions announced today by the chief executives of the four counties are in alignment with the state of Hawaiʻi’s recent commitment to the goals of the Paris Agreement that seeks to reduce GHG emissions and keep global warming below 1.5 degrees Celsius. Sea level rise is contributing to coastal erosion that recently destroyed part of a historic cemetery on Maui and caused a bike path on the North Shore of Oʻahu at Sunset Beach to partially collapse; and according to the recently published Hawaiʻi Sea Level Rise Vulnerability and Adaption Report, the expected future sea level rise is estimated to cost $19 billion in “loss of land and structures” along with 6,500 flooded structures, 38 miles of flooded major roads, and 19,800 displaced people.
