The Most Energy-Efficient Manufacturing Plants of 2023

Last week, the EPA recognized the 103 U.S. factories to earn Energy Star certification in 2023. The award recognizes manufacturing plants in the top 25% of energy efficiency in their sector. According to the EPA, these plants prevented more than 8 million metric tons of CO2 emissions—that's the equivalent to the emissions from electricity used by more than 1.5 million homes.
