SB 2999: RELATING TO A CLEAN FUEL STANDARD.

SB 2999 requires the state Department of Transportation to create and adopt rules by January 1, 2028, establishing a clean fuel standard for alternative transportation fuels like electricity and biofuels. This rulemaking will directly affect fuel providers, refiners, and the state's transportation sector by setting requirements for reducing carbon emissions in these fuels. The bill mandates the DOT to develop specific standards for cleaner fuel use, focusing on lowering greenhouse gas emissions from transportation. It does not set immediate fuel requirements but establishes a timeline for the agency to create enforceable rules. The legislation is currently in committee review after its introduction in January 2026.

HCR 98: REQUESTING THE DEPARTMENT OF HOUSING AND LAND MANAGEMENT OF THE CITY AND COUNTY OF HONOLULU TO DEVELOP A COUNTYWIDE HOUSING PATTERN BOOK TO STREAMLINE PERMIT APPROVALS AND REDUCE REGULATORY BARRIERS FOR SAFE, AFFORDABLE, AND WELL-DESIGNED HOMES.

This bill requests the Honolulu Department of Planning and Permitting to create a countywide housing pattern book containing pre-approved residential designs that meet safety and building codes. The pattern book would include various housing types such as accessory dwelling units and low- to mid-rise buildings, featuring culturally appropriate and climate-responsive design elements. By using these pre-reviewed designs, developers could access streamlined permitting processes to reduce costs and construction delays. The resolution also calls for a design competition to source innovative plans and requires collaboration with architects, builders, and community stakeholders. Once completed, the pattern book would be made publicly available to help accelerate the production of safe and affordable housing across Oahu.
