HI Clean Fleets Toolbox

Welcome to Hawaii Climate Change Mitigation and Adaptation Commission’s  Clean Fleets Toolbox! This page emerged from brown bag discussions at DLNR, and is, hopefully, helpful to public fleets managers and staff in Hawaii as they transition vehicles from petroleum and petro-diesel to cleaner alternatives. If you have resources to share, please send them our way, and feel free to use ours! Mahalo!

DLNR is fully committed to taking ambitious action over the next five years to accelerate achieving State goals for renewable energy and efficiency standards in its buildings, facilities, and vehicles; and providing incentives to its employees to encourage actions that will affect behavior and mode-shift throughout the State of Hawaii. Here we identify and outline some near-term strategy components currently being investigated and piloted by us. 

Currently, DLNR’s fleet, which mainly consists of trucks, operates on gasoline or petro-diesel. Given these characteristics, a three-fold emissions reduction strategy is recommended for DLNR to 1)  Transition its fleet to clean renewable/alternative fuels (increase the proportion of renewable/clean energy in its total energy/fuel use; 2) Make its fleet as fuel efficient as possible (increase fuel efficiency); and 3) Right size its fleet to reduce emissions. Specifically, DLNR could:

  1. Switch to renewable and low emission biodiesel B100 for its trucks;
  2. Adhere to vehicle procurement hierarchy, but emphasize ICE hybrid vehicle procurement to lower emissions, where there are no EV or alternative fuel options;
  3. Develop and deploy charging infrastructure for EVs;
  4. Procure EVs for DLNR’s light duty passenger vehicles, and install telematics;
  5. Develop a carshare program for DLNR’s light duty vehicles; and
  6.  Investigate alternative fuels such as hydrogen, renewable natural gas, and others.
