NorthWestern Energy donating $3,200 in honor of employees and their families walking or biking more than 3,200 miles instead of driving during Earth Week

Sioux Falls, SD/Butte, Mont. – April 19, 2023 – NorthWestern Energy is donating $3,200 to One Tree Planted in honor of our employees and their families who committed to avoid driving at least 3,200 miles during Earth Week.

“We challenged our employees to leave their vehicles parked when possible and walk or bike instead,” said NorthWestern Energy President and CEO Brian Bird. “They enthusiastically accepted our challenge. By driving less they will avoid at least 2,460 pounds of tailpipe carbon emissions this week. We are supporting tree planting to do even more for the environment.”

Some employees and members of their families walked to work or school while others biked to do errands.

“Our whole family took the challenge,” said NorthWestern Energy Communications & Marketing Coordinator Eric Thorsrud.  “We are all more aware of how with a little planning, we can leave our car parked more often. It was actually a lot of fun, good for our health and something we will continue.”

NorthWestern Energy’s donation is designated to plant 3,200 trees in the Custer Gallatin National Forest in Montana.

The mission of non-profit One Tree Planted is to make it simple for anyone to help the environment by planting trees. Their projects span the globe and are done in partnership with local communities and knowledgeable experts to create an impact for nature, people, and wildlife.
