Hawai‘i

As a small island state with non-energy intensive industries and a mild climate, Hawai‘i has one of the lowest total and energy consumption per capita among all states. The state was the first to legally commit to a zero-emissions economy by 2045 and has decreased emissions by 19% from 2005-2021. Both in-state electricity generation and consumption are dominated by petroleum, with about one-fifth of generation coming from renewables, a majority of which is solar. Hawai‘i has the highest average electricity price of any state because of high fuel import costs.

Progress by Policy Area

Enacted Enacted policies have been passed or established in a state by a governing body via legislation, executive orders, rules, regulations, and/or other program creation, and remain in effect.
In-progress In progress policies have been established in a state, but final regulations, rules, or plans are pending final approval. This also includes legislation and executive orders that require regulations to be put into effect.
Partially Enacted Partially enacted policies have been enacted in the state, but are missing one or more policy components. Dashboard policies cannot be considered partially enacted unless policy components are available.
Not Enacted Not enacted policies have not been passed or established in the state or are no longer in effect.

Glossary of Terms

The colored bars indicate the status for each policy on the Dashboard, viewed across seven policy areas.

Status	Policy	Policy Area	Policy Category	Year Enacted
Not Enacted	Low-Emission Vehicle (LEV) Standards Empty column Under Section 177 of the Clean Air Act, California has the unique authority to establish vehicle emission standards more stringent than federal standards, and other states may adopt California’s standards. These Low-Emission Vehicle (LEV) standards control tailpipe emissions of criteria pollutants and greenhouse gasses from light-duty vehicles.	Transportation	Light-Duty Vehicles
Not Enacted	Zero-Emission Vehicle (ZEV) Mandates Empty column Zero-Emission Vehicle (ZEV) mandates, also known as "clean car standards," require automakers to produce and sell a certain percentage of zero-emission light-duty vehicles each model year based on total new vehicle sales. The most stringent ZEV mandates require 100% of new vehicle sales to be electric by 2035 and are known as "Advanced Clean Cars II".	Transportation	Light-Duty Vehicles
Not Enacted	Electric Vehicle Rebates Empty column Electric vehicle rebates offer rebates to make light-duty electric vehicles more affordable to increase their adoption in a state.	Transportation	Light-Duty Vehicles
Not Enacted	Low NOx Omnibus Rules Empty column Low NOx Omnibus Rules establish stringent tailpipe emission standards for heavy duty vehicles, updated testing procedures, and technology-neutral compliance mechanisms to reduce nitrous oxide (NOx) pollution. The regulation must be adopted first by California, and other states may adopt the regulation under the federal Clean Air Act.	Transportation	Medium- and Heavy-Duty Vehicles
Not Enacted	Medium- and Heavy-Duty (MHD) Zero-Emission Vehicle (ZEV) Mandates Empty column Medium- and heavy-duty (MHD) zero-emission vehicle mandates, also known as "Advanced Clean Trucks", require automakers to produce and sell a certain number of zero-emission MHD vehicles to fulfill a quota based on a percentage of total sales in states.	Transportation	Medium- and Heavy-Duty Vehicles
Not Enacted	Medium- and Heavy-Duty Electric Vehicle (EV) Rebates Empty column Medium- and heavy-duty (MHD) electric vehicle rebates consist of programs and policies that offer rebates to make MHD electric vehicles more affordable to increase their adoption in a state.	Transportation	Medium- and Heavy-Duty Vehicles
Enacted	Public Fleet Electric Vehicle (EV) Procurement Targets Empty column 30% of the state's light-duty vehicle fleet are ZEVs by 2025 \| 60% are ZEVs by 2030 \| 100% are ZEVs by 2035 Establishing Policies HB 552 (2021)	Transportation	Lead by Example	2021
Not Enacted	Electric Bus Procurement Targets Empty column Electric bus procurement targets require that a certain percentage or number of school buses and/or transit buses purchased or leased by the state, transit authorities, and/or school districts must be electric or zero-emissions.	Transportation	Lead by Example
Not Enacted	Electric Vehicle (EV) Charging Infrastructure Requirements Empty column Electric vehicle (EV) charging infrastructure requirements establish mandates for the installation of EV charging infrastructure in new construction or developments, such as residential or commercial buildings, and public parking lots.	Transportation	EV Charging Infrastructure
Enacted	Electric Vehicle (EV) Charging Infrastructure Rebates Empty column The EV Charging Stations rebate program offers rebates for the purchase and installation of EV chargers for commercial entities, workplaces, and multifamily dwellings, up to $4,500 for Level 2 and up to $35,000 for direct current (DC) fast chargers. Establishing Policies HB 1585 (2019) EV Charging Stations rebate program	Transportation	EV Charging Infrastructure	2019
Not Enacted	Electric Vehicle (EV) and EV Charging Infrastructure Plans Empty column Electric vehicle (EV) and EV charging infrastructure plans are documents that provide a framework to guide the development, coordination, and adoption of EVs and EV charging infrastructure.	Transportation	Transportation Plans and Targets
Enacted	Transportation Greenhouse Gas Emissions Reduction Targets Empty column Net-zero emissions by 2045 Establishing Policies SB 1024 (2023)	Transportation	Transportation Plans and Targets	2023
Not Enacted	Low Carbon Fuel Standards Empty column A low carbon fuel standard (LCFS) is a market-based mechanism to reduce the carbon intensity of transportation fuels and account for the fuel's life cycle greenhouse gas emissions.	Transportation	Transportation Plans and Targets
Partially Enacted	Bicycle Friendly States Empty column Hawai‘i is ranked 25th out of 50 in the 2024 Bicycle Friendly State rankings by the League of American Bicyclists.
