The information below summarizes actions taken by Hawai'i to adapt to the impacts of climate change. Hawai'i has not yet adopted an official statewide adaptation plan, however, the state legislature has called for adaptation planning and state agencies have undertaken other efforts to assess climate vulnerabilities and identify adaptation strategies, described here.
On June 9, 2014, Hawai'i Governor Neil Abercrombie signed House Bill 1714 (now Act 83) establishing an Interagency Climate Adaptation Committee charged with developing a sea-level rise vulnerability and adaptation report addressing statewide impacts through 2050. In 2017, the state legislature passed Senate Bill 559 that renamed the Adaptation Committee as the Hawai'i Climate Change Mitigation and Adaptation Commission (“Commission”). The Commission is charged with developing vulnerability and adaptation reports on the effects of sea-level rise and leading the state’s efforts to reduce greenhouse gas emissions in line with goals set out in the Paris Agreement. In addition to setting goals and strategies for both mitigation and adaptation, the Commission is charged with identifying climate vulnerabilities across all sectors in Hawai'i; assessing existing efforts and capacity of existing resources to address goals; and tracking and reporting on implementation progress.
Vulnerability Assessment and Planning
In December 2017, the Commission released the Hawai'i Sea Level Rise Vulnerability and Adaptation Report. This report represents the first state-wide vulnerability assessment for sea-level rise hazards in Hawai'i and provides statewide adaptation recommendations to reduce Hawai'i’s exposure to sea-level rise and to increase the state’s resilience to coastal hazards.
State Agency Actions
State agencies have also been working to prepare for climate impacts to specific sectors:
State Legislative Actions
The state legislature has also adopted adaptation priorities to guide adaptation activities at the state level. In July 2012, the Hawai'i legislature passed SB 2745/HB 2483, which sets climate change adaptation priority guidelines for integrating climate adaptation into statewide planning processes. The law establishes the following adaptation priorities: exploring adaptation strategies that moderate harm or exploit beneficial opportunities in response to actual or expected climate change impacts to the natural and built environments; promoting sector resilience (in areas such as water, roads, airports, and public health) by encouraging the identification of climate change threats, assessment of potential consequences, and evaluation of adaptation options; using adaptive management approaches; and encouraging planning and management of natural and built environments that consider climate change.
The state legislature has also enacted laws to provide financial resources to support adaptation efforts. In 2015, the legislature passed House Bill 444 — An Act Relating to Beach Protection — to allocate $3,000,000 of hotel tax revenues to a special fund supporting the development and implementation of plans to slow the degradation of Hawai'i’s beaches; beach restoration and conservation efforts; the coordination of activities across counties; and the formation of public-private partnerships. The legislation allows the Hawai'i Department of Land and Natural Resources to include studies about the effects of sea-level rise when developing beach conservation plans. In 2010, through Hawai'i Act 73, the state legislature also established the “environmental response, energy, and food security tax,” otherwise known as the “barrel tax,” to provide resources for addressing the effects of climate change in the state. Act 73 increased the per-barrel tax on petroleum products and created a fund for clean energy, agriculture, and adaptation initiatives in Hawai'i.
To support local and private sector adaptation efforts, the state has developed an Adaptation Portal to provide information to the public about the impacts of climate change, and adaptation strategies and tools.
This page highlights the actions Hawai'i is taking to adapt to the impacts of climate change. Other resources from the Adaptation Clearinghouse, which have been developed and adopted to help Hawai'i prepare for the impacts of climate change, are featured in the chart below.
The Georgetown Climate Center’s State Adaptation Progress Tracker, which tracks the progress states are making in preparing for the impacts of climate change, was supported by the MacArthur Foundation.
