EPA – 2023 Top Energy-Efficient Manufacturing Plants

The U.S. Environmental Protection Agency today recognized the 103 U.S. manufacturing plants that earned the agency’s ENERGY STAR certification in 2023, a title for plants in the top 25% of energy efficiency in their sector. These plants in sum prevented more than 8 million metric tons of carbon dioxide emissions, equivalent to the emissions from the electricity use of more than 1.5 million American homes.

“President Biden’s Investing in America agenda is breathing new life into energy efficient domestic manufacturing, and industry partners like those recognized today are leading the way,” said EPA Administrator Michael S. Regan. “These ENERGY STAR certified plants demonstrate that cutting the embodied carbon of our industrial products through energy efficiency doesn’t just make environmental sense, it makes economic sense.”

The industrial sector accounts for 30% of U.S. greenhouse emissions, primarily from energy use in manufacturing plants. ENERGY STAR certified plants have reduced their energy use through a variety of energy efficiency projects and management practices.

During 2023 in the automotive sector Nissan North America, Inc., replaced more than 20,000 light fixtures with LEDs in all U.S. manufacturing sites and conducted a combination of energy treasure hunts and third-party assessments targeting energy efficiency, according to the EPA. General Motors, Honda and Nissan plants were already on the list.

Manufacturing plants use EPA’s ENERGY STAR energy performance indicators or, in the case of petroleum refineries, the Solomon Associates Energy Intensity Index scoring system, to assess their energy performance. Plants that score at least 75 out of 100, meaning that they are more energy efficient than 75% of similar facilities nationwide, are eligible to earn ENERGY STAR certification.

ENERGY STAR certification is available for 21 manufacturing sectors, from cement and steel to glass and commercial bakeries. More than 270 plants have achieved ENERGY STAR certification since 2006. Search Here
