ABOUT OUR REPORT
The scope of this report is Fiscal Year 2018, covering
July 1, 2017 through June 30, 2018. Our most recent
report was published in February 2018. We intend to
report on an annual basis in the future.
The report has been prepared in accordance with the
GRI Standards: Core Option. For estimating our fleet vehicle emissions, TRC uses
the mileage tracked for each vehicle in conjunction with
standard emissions factors provided by FuelEconomy.
gov, which is maintained by the U.S. Department of
Energy’s Office of Energy Efficiency and Renewable
Energy. This data takes into account each vehicle’s
make, model, and production year.
We have chosen to not externally assure this report but
may elect to do so in the future. There have been no restatements or significant changes
from our prior report.
We chose “operational control” as the emissions con-
solidation approach using World Resources Institute
and the World Business Council for Sustainable Devel-
opment Greenhouse Gas Protocol Initiative-A Corporate
Accounting and Reporting Standard (Revised Edition,
2015) as guidance. In June 2018, TRC acquired Vali Cooper & Associates
Inc., a California infrastructure firm that manages
transportation, water/wastewater, utility and facilities
projects.
