GCC’s Rapid City Plant earned the U.S. Environmental Protection Agency’s (EPA) 2023 ENERGY STAR® certification for superior energy efficiency. This is the fourth consecutive year the Rapid City Plant earned the prestigious certification, reflecting our commitment to energy efficiency and reduced emissions.

“ENERGY STAR certification highlights GCC’s status within the top 25 percent of cement plants in the nation concerning energy performance,”

Ron Henley, U.S. Division President

“We are committed to environmental stewardship while also lowering our costs through operational improvements in the efficient use of energy.”

GCC improved its energy performance by managing energy and investing strategically across the organization. To earn the ENERGY STAR, GCC enhanced efficiency at the Rapid City Plant by upgrading its preheater and improving kiln combustion efficiency. They also continued adopting alternative fuels, reducing CO2 emissions while maintaining optimal energy use. This reflects GCC’s commitment to sustainability and innovation.

GCC’s Pueblo, Colorado, plant also earned an ENERGY STAR for the sixth consecutive year and was the only cement plant in Colorado to receive the prestigious award. This achievement places GCC among the country’s eleven ENERGY STAR-certified cement plants.

“Improving the energy performance of our nation’s industrial plants is critical to reducing greenhouse gas emissions,” said Cindy Jacobs, Chief of the ENERGY STAR Commercial and Industrial Branch. “EPA applauds the commitment to energy efficiency demonstrated by ENERGY STAR-certified plants.”

ENERGY STAR was introduced by the Environmental Protection Agency in 1992 as a voluntary, market-based partnership to reduce greenhouse gas emissions through energy efficiency. To date, tens of thousands of buildings and plants across all fifty states have earned the ENERGY STAR.
