Highlights from Chapter 3

Energy and Emissions

  • In 2022, we had a 17 percent rise in construction equipment hours, but only a 7 percent increase in fuel consumption of construction equipment. This is attributed to our continued progress toward our zero-emission goals for construction vehicles.
  • We achieved a net-positive greenhouse gas (GHG) balance in 2022, offsetting more GHG emissions than the project had generated to date.
  • Approximately 32 percent of the total electricity consumed in 2022 came from renewable sources, an increase from 31 percent in 2021.
  • Future construction packages incorporate provisions mandating the use of zero-emission vehicles for on-site travel, which will lead to reduced fuel consumption during construction.
  • In terms of air quality, our construction vehicles emitted 68 percent less black carbon in 2022 than a typical fleet.
