What is Sustainability?
Sustainability is based on a simple principle – everything that we need for our survival and well-being depends, either directly or indirectly, on our natural environment. Sustainability creates and maintains the conditions under which humans and nature can exist in productive harmony, that permit fulfilling the social, economic and other requirements of present and future generations.
Sustainability is important to making sure that we have, and will continue to have, the water, materials, and resources to protect human health and our environment.

Commitment to Sustainability at DHX - Dependable Hawaiian Express
The nature of our transportation and logistics business generates a large share of greenhouse gases. We are committed to reducing our carbon footprint and to increase our effectiveness and capacity to be innovative in a way that we make positive impact on society.

This will mean managing for the long-term as well as the short-term, developing strategies that balance competition and cooperation, and providing a service that meets social and environmental needs. For us, sustainability needs to be about ‘greening’—because businesses and communities depend on healthy, productive ecosystems. We have made it our mission to be the leader in our industry, and we invite you to share in this pursuit. Read about our Fuel Conservation Program.

  • GreenWay Miles testimonial regarding DHX - Dependable Hawaiian Express:

May 2017

My sincerest congratulations to Dependable Hawaiian Express (DHX) for achieving a year-over-year reduction in carbon emissions at each of the five locations audited. Their commitment to annual emission measurement and reduction positions DHX as a transportation leader in the field of environmental sustainably.

In addition to participating in EPA’s SmartWay Program, Dependable Hawaiian Express also invests in an annual GreenWay Miles carbon audit allowing them to define their complete carbon footprint. SmartWay carbon emission data includes only fleet emissions. However, facility operations are a major contributor to any trucking company’s carbon footprint and DHX’s carbon audit captures and combines both fleet and facility emissions.

The audit calculated fleet and facility carbon emissions for each of their five locations and expressed results in terms of Total Tons of Carbon, Grams of Carbon per Total Mile and Grams of Carbon per Loaded Mile.

Included with the audit is a carbon calculator that converts loaded miles into grams of carbon per mile based on audit results. This allows shippers using DHX to calculate grams of carbon emissions for a single load or for an entire year’s worth of shipments.

In addition to providing a complete accounting of their carbon emissions, DHX’s investment in a greenhouse gas protocol audit also provides environmentally conscious shippers the ability to purchase carbon offsets* to offset emission levels or to ship freight on a carbon neutral basis.

This is DHX’s fifth GreenWay Miles carbon audit and we commend them for their continued commitment to providing shippers a complete, accurate and transparent metric of their carbon emissions and the ability to offset those emissions if desired.

Joe White
CEO, GreenWay Miles

* Carbon offsets are investments in projects that reduce carbon emissions. Examples include solar panels and windmills. Shippers wishing to offset their emissions should contact DHX for details.

  • As part of its 2014-2015 Hawaii Clean Fleets certification program, DHX was awarded the Blue Planet Foundation “Certified Clean Fleet” status.

Our Achievements
  1. We invested $2.2 million in new trucks to support the Clean Truck Act, in accordance with the Clean Truck Act enacted by the Ports of Los Angeles and Long Beach to reduce emissions.
  2. Our Maui facility is solar sufficient - totally energy efficient with no energy used off the Island electric grid.
  3. We have 2% sky lights at various facilities to use natural, rather than artificial lighting.
  4. We meet the California Air Resources Board’s “sparklist” requirements. The company invested $525,000 in new forklifts to reduce emissions.
  5. We are working to estimate our carbon footprint for all our trucking operations and are taking steps to reduce our carbon emissions.
  6. We are an active Partner with Smartway, a US Government EPA partnership with truckers, to improve our fuel and use of oil efficiency, and reduce our emissions. SmartWay Certificate
  7. In our Los Angeles headquarters we have installed four charging stations for employee use to charge electric vehicles.
  8. We have installed lower energy usage models for lighting, converted our Corporate Headquarters outside lights to LED and use timers to increase the effectiveness of our HVAC and lighting systems.
  9. We recycle paper in our Los Angeles corporate headquarters, our San Leandro facility and our Seattle facility. With separate trashcans to collect recyclables along with a new computer system that is virtually paperless, we are reducing the consumption of paper.
  10. We replaced our networking infrastructure in April 2011, becoming more energy efficient in the process. Approximately $56,000 was spent on new hardware switches, dropping energy consumption by 38%.
  11. Over three years, we consolidated our servers and services in the computer room reducing the count and need for a number of separate servers.
  12. We dropped our net server energy consumption by 33% and an indirect energy savings on cooling by having less equipment generating heat.

  1. Publish No-Idling Policy, No Out-of-Route Policy and MPG goals for Drivers. Sent a letter out to Drivers explaining the new policy and MPG goals and how they tie into our Sustainability Policy.
  2. Monitor and manage individual truck MPG actual-to-goal performance. We compare Driver performance on same-model equipment and use the ‘bottom 15%’ technique for managing and coaching worst performing Drivers.
  3. We look for rotation opportunities—for example—and place highest MPG equipment on longest runs based on miles/month. Likewise, we ensure if we have idle equipment, it is always our lowest MPG performing equipment.
  4. Management is currently considering, but has not implemented, a shared savings bonus program based on improved MPG performance. For example, if average company MPG increases 0.2 Miles per Gallon and that generates a $230,000 annual savings for the company, we would pay $90,000 out in bonus to the Drivers and Managers.
  5. During Orientation, we train Drivers on sustainability and review the above mentioned policies/MPG goals and below outlined Driver Activities to reduce Fuel Consumption.
  1. Reduce Idling. Take every opportunity to shut off your engine. Each idle hour burns 8/10 of a gallon of fuel. A 100-truck fleet that reduces idling by 2 hours/truck/week will save 40,000 gallons of fuel/year, about $150,000 in cash and will eliminate a volume of carbon emissions that would fill 4.7 fifty-three-foot trailers.
  2. Reduce Highway Top Speeds. This may involve use of speed governors. Reducing speed by one MPH equates to an approximate mileage increase of 1/10 Mile per Gallon.
  3. Driving Techniques. How a truck is driven will have a significant impact on MPG. Fuel conserving driving techniques include: Smooth Shifting & Breaking, Block Shifting (ex: from 2nd to 5th gear), Cruise Control and Progressive Shifting (up shift at lowest RPM possible).
  4. Tire Pressure. Make sure Drivers frequently check tire pressure. Truck tires inflated 10 pounds per square inch (psi) below recommended air pressure levels can reduce truck fuel economy between 0.5 percent and 1 percent.
