Eighty-six U.S. manufacturing plants earned 2022 ENERGY STAR certification
The Environmental Protection Agency’s (EPA’s) ENERGY STAR certification is reserved for manufacturing plants in the top 25 percent of energy efficiency in their sector. Eighty-six manufacturing plants earned this certification in 2022. Combined, these plants saved over 105 trillion British thermal units of energy and prevented over 6 million metric tons of carbon dioxide emissions.
The industrial sector is responsible for 30 percent of U.S. greenhouse gas emissions, mainly from energy use in manufacturing plants. Ohio has the most ENERGY STAR certified manufacturing plants of 2022 out of all the states, with 10. The following are examples of some of the manufacturing plants and how they achieved this certification:
- Ash Grove’s Seattle, Washington, cement plant automated the support equipment in their grinding mills to stop operation when the mills do.
- Astra Zeneca’s Newark, Delaware, pharmaceutical plant installed a heat recovery system that decreased natural gas usage by about 20 percent and a heat exchanger that provides free chilled water during winter months.
- General Motors’ Fort Wayne, Indiana, auto assembly plant recovered waste heat from the engine jackets and exhausts ducts of its landfill gas cogeneration units, lowering the plant’s winter natural gas consumption.
One year alone of ENERGY STAR can make a significant impact. For example, in 2020, the program’s emissions reductions were equivalent to over five percent of U.S. total greenhouse gas emissions.
ENERGY STAR’s 2020 energy savings led to reductions of:
- 210,000 short tons of sulfur dioxide,
- 210,000 short tons of nitrogen oxides, and
- 20,000 short tons of fine particulate matter.
This avoided air pollution was responsible for an estimated $7 to $17 billion in public health benefits.
Key to remember: Eighty-six manufacturing plants earned the ENERGY STAR certification in 2022, which is reserved for manufacturing plants in the top 25 percent of energy efficiency in their sector.
