TRC | 2017 SUSTAINABILITY REPORT
ABOUT OUR REPORT
The scope of this report is Fiscal Year 2017, covering July 1, 2016 through June 30, 2017. Our most recent report
was published in February 2017. We intend to report on an annual basis in the future.
The report has been prepared in accordance with the GRI Standards: Core Option.
We have chosen to not externally assure this report, but may elect to do so in the future.
We chose ‘operational control’ as the emissions consolidation approach using World Resources Institute and the
World Business Council for Sustainable Development Greenhouse Gas Protocol Initiative-A Corporate Accounting
and Reporting Standard (Revised Edition, 2015) as guidance.
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, with data provided by the U.S. Environmental Protection Agency.
This data takes into account each vehicle’s make, model and production year.
Restatements or significant changes from our prior report are addressed in their respective areas of the report and
include the following:
■ ■ Acquisitions are incorporated into our environmental footprint metrics one year later. Footprint metrics from
the CALTROP acquisition will be incorporated in the FY18 reporting year.
■ ■ Materiality Assessment: added Diversity
■ ■ Stakeholder Engagement: added New Mountain Capital as a key stakeholder
