There are Scope 3 emissions that were not included in the current GHG emission calculations. These emission sources could be considered in future inventory plans.
Local Commuter Travel
Supply Chain Transportation
Embodied carbon due to construction materials
Emissions from subcontractors
Why did we use 2019 to establish a baseline?
The COVID-19 pandemic resulted in significant changes in USE operations between March 2020 and June 2021. We wanted to understand how these changes affected our GHG emissions and compare them against a period of normal operations.
Therefore, USE established 2019 as the baseline year and will base our initial sustainability report on emissions measured over calendar years 2019, 2020 and 2021.
How did U.S. Engineering use GHGs over the past few years?
2022 by percentage
Fuel consumption of U.S. Engineering fleet vehicles continues to be the largest contribution (54% of the company total). Our fleet traveled over 3.1 million miles in 2022, evenly split among the Midwest and Rocky Mountain regions. Our Rocky Mountain Region operations accounted for 52% of the total fleet mileage.
Facility emissions result in the next highest source of emissions at 34% of the total, with purchased electricity at 21% and natural gas usage at 13%.
Team member business travel at 6% and product transportation at 6% make up the remainder of USE’s emissions profile.
