Yard Trucks: We’ve been running zero emissions electric yard trucks, similar to Autocar’s all-electric terminal tractor (E-ACTT), in our distribution centers over the last year and have found they provide approximately a 50% emissions reduction compared to diesel trucks, taking into account how the electricity is created and delivered to power these units. Our goal is to continue working to pair these trucks with renewable energy like wind, solar, or hydro powers, so we can achieve a true 100% emission reduction.
Refrigerated Trailers: We also have an opportunity to power our refrigerated trailers with electric energy. As the world’s largest grocer, we use 10,000 of these refrigerated trailers to safely distribute fresh and cold groceries to stores. Today, they rely on diesel fuel to keep them cold, which contributes to our overall CO2 emissions.
To change this, we recently worked with Thermo King to haul Walmart’s first-ever refrigerated trailer operated on battery electricity in the U.S. The trailer is designed to run on 100% electricity until the batteries are fully depleted. If the electricity is depleted mid-haul, the refrigeration unit cuts over to diesel.
