THIRTY-THIRD LEGISLATURE, 2026

STATE OF HAWAII

A BILL FOR AN ACT

relating
to renewable fuel
.

BE IT ENACTED BY THE LEGISLATURE OF THE STATE OF HAWAII:

����
SECTION
1
.
�
The legislature finds that, because of the
recent
Navahine F. v. Hawai
ʻ
i Department of
Transportation
CIV. NO. 1CCV-24-0000631 (Hawai
ʻ
i
Cir. Ct.) settlement, there is a clear need for the State to take meaningful
and coordinated action to reduce its greenhouse gas emissions, particularly
within the transportation sector.
�
The
settlement underscores the State's constitutional responsibility to ensure a
life‑sustaining climate for current and future generations.
�
It also calls for the development and
implementation of a comprehensive energy security and waste reduction plan to
guide decarbonization efforts over the next twenty years, including the
adoption of sustainable aviation fuel as a key strategy.

����
The legislature further finds that the transportation
sector is the single largest contributor to greenhouse gas emissions in Hawaii,
accounting for forty-eight per cent of statewide emissions, well above the
national average.
�
Within that sector,
aviation plays a critical role, supporting commerce, tourism, and essential
interisland travel, and contributes significantly to overall emissions.
�
Hawaii consumes approximately seventeen
million barrels, or seven hundred fourteen million gallons of jet fuel annually.

�
Transitioning this system away from
fossil fuels is essential to achieving the State's climate goals.
�
Even producing a modest portion of that fuel
locally, using renewable feedstocks, can yield outsized benefits, stimulating
local agriculture, creating economic opportunities, reducing emissions, and
building energy resilience.
�
Rather than
continuing to grow the State's annual fossil fuel demand by small increments
each year, Hawaii has the opportunity to stop that trajectory and instead take
a bold, measurable step toward emissions reduction and local sustainability in
a single year.

����
The legislature recognizes that renewable
fuel used for sustainable aviation fuel (SAF) offers a near-term and scalable
solution to decarbonize aviation without requiring changes to aircraft or
infrastructure.
�
However, SAF remains
several times more expensive than conventional fuels.
�
Without targeted policy support, including
financial incentives, local SAF production and adoption will remain
cost-prohibitive.
�
Other states have
enacted policy tools and tax credits to bridge this gap.
�
The State must act similarly to remain
competitive, meet its legal obligations, and seize the economic opportunities
offered by renewable fuel production.

����
Updating the renewable fuels production tax
credit to increase incentives is a critical component of this effort.
�
Revising this tax credit will support local
production of SAF and other renewable fuels, enabling investment in energy
infrastructure, job creation, and economic development.
�
These fuels benefit a broad spectrum of the
State's residents, from households that rely on propane for cooking to patients
who depend on affordable interisland flights for medical care, ensuring that
climate action is equitable and far-reaching.

����
The legislature believes that an updated renewable
fuels production tax credit also encourages agricultural innovation by
supporting energy crops that serve as regenerative cover crops, helping to
restore soil health while complementing food production and requiring minimal
water.
�
These crops offer farmers an
additional source of revenue and generate byproducts that can be used as feed
for local livestock and aquaculture, reinforcing both food and energy
resilience.
�
Importantly, this transition
creates new jobs in agriculture, a sector that will play a vital role in the
State's renewable fuels future and long-term sustainability.
�
Moreover, local renewable fuel production
supports skilled employment, allowing Hawaii's refinery workforce to adapt and
thrive in a clean energy economy.
�
These
jobs offer long-term, high-value career pathways for residents and contribute
to workforce development aligned with the State's decarbonization goals.

����
Accordingly, the purpose of this Act is to
fulfill the State's climate commitments by expanding the renewable fuels
production tax credit.

����
SECTION
2
.
�
Section 235-110.32, Hawaii Revised Statutes,
is amended as follows:

����
1.
�

By amending subsection (a) to read:

����
"(a)
�

Each year during the credit period, there shall be allowed to each
taxpayer subject to the taxes imposed by this chapter a renewable fuels
production tax credit that shall be applied to the taxpayer's net income tax
liability, if any, imposed by this chapter for the taxable year in which the
credit is properly claimed.

����
For each taxpayer producing renewable
fuels,
the annual dollar amount of the renewable fuels
production tax credit during the ten-year credit period

Code and all business entities under common control, as determined under
sections 414(b), 414(c), and 1563(a) of the Internal Revenue Code, shall not be
eligible for more than a single [
ten-year

The total aggregate amount of additional
credit value for sustainable aviation fuel under subsection (a)(4) shall not
exceed the sustainable aviation fuel additional value cap.
�
To the extent that the proportional allocation
and applications of the single producer cap and sustainable aviation fuel
additional value cap results in total credits lower than the program cap, the
difference between the program cap and the total shall be allocated to any
remaining eligible claims from taxpayers that have not exceeded either the single
producer cap or sustainable aviation fuel additional value cap in proportion to
