The DRR program provides rebates for the replacement of medium- and heavy-duty diesel vehicles with new, battery-electric equivalents. Presented by the Hawaii State Energy Office in partnership with the Hawaii Department of Health, the DRR is funded by the Volkswagen Environmental Mitigation Trust, and the Diesel Emissions Reduction Act.
Hawaii has a goal of a net-negative carbon economy as soon as practicable but no later than 2045. This goal is supported by Hawaii’s objective to increase energy security and self-sufficiency by planning for the reduction and ultimate elimination of Hawaii’s dependence on imported fuels for electrical generation and ground transportation.
In 2020, Hawaii joined with 14 other states and the District of Columbia as signatories to the Multi-State Medium- and Heavy-Duty Zero Emission Vehicle Memorandum of Understanding (MOU) which, among other things, is an agreement to strive to make sales of all new medium- and heavy-duty vehicles in their jurisdictions zero emission vehicles by no later than 2050. To ensure adequate progress toward the MOU 2050 goal, the signatory states aspire to make at least 30 percent of all new medium- and heavy-duty vehicle sales in their jurisdictions zero emission vehicles by no later than 2030.
The Diesel Replacement Rebate is one way that Hawaii is supporting its community and encouraging the transition to zero-emission vehicles.
