Sustainable Environment

Energy & Emissions

For nearly 140 years, we have built our business on valuing the natural capital of trees, plant life and animal habitats created for our homes and communities. As we begin to see evidence of a changing climate in our work and research, we have the capability and responsibility to act on climate change and create positive impacts through our environmental services. In addition, we will continue to work internally to reduce our carbon emissions and fossil fuel use.

Management Approach

103-1, 103-2, 103-3

Each day, our employees travel across North America, providing our clients proven solutions for a growing world. In fact, Davey operates one of the 50 largest corporate fleets in the U.S., with nearly 10,000 vehicles traveling more than 50 million miles each year.

The energy use and affiliated emissions from our fleet of vehicles and field equipment represent approximately 95 percent of our total Scope 1 and 2 emissions. Therefore, managing our fleet and equipment—ensuring each item is properly used, as well as serviced regularly and maintained—offers the most actionable opportunity to decrease our emissions and energy use.

In 2017, we began implementing Fleet 2020, our new fleet management system. The system provides comprehensive tracking of fleet data, including:

  • Vehicle history
  • Registration status
  • Maintenance schedules
  • Vehicle repair status
  • Fuel use
  • Capital expenditure requests

Available electronically, Fleet 2020 fully integrates into our existing management system and across devices. In addition, Fleet 2020 will enable automated fleet analyses, such as vehicle total cost of ownership, and help inform decisions about vehicle acquisition, operations and retirement.

In 2017, we established a bold goal to reduce our global fleet fuel consumption by 35 percent per labor hour by 2023 from a 2017 baseline. We are investigating several mechanisms to achieve this goal, including:

  • Renewable and alternative fuels
  • Telematics and driver behavior monitoring
  • Energy efficiency and route optimization
  • Partnering to innovate and acquire environmentally friendly equipment

In 2019, we began replacing our fleet vehciles with hybrid vehicles and expect to save 110,000 gallons of gas per year by the time the change is fully implemented. We continue to investigate alternative fuels and lithium ion technology for the right fit in our operations.  Equipping 100 percent of Davey’s fleet with GPS will enable real time monitoring location, speed, acceleration and idling. Through proactively monitoring driver behavior and promoting good driver habits, we can substantially reduce fleet fuel use.
