The Trump administration’s latest move to roll back climate-related funding has put the U.S. cement industry in turmoil, canceling flagship projects that were meant to showcase American leadership in low-carbon manufacturing.
In May, the Department of Energy abruptly terminated a $500 million grant to Heidelberg Materials for its cement plant in Mitchell, Indiana. The facility was supposed to pioneer carbon-capture technology capable of trapping millions of tons of CO₂ and storing it underground — a model that industry leaders hoped would put the U.S. at the forefront of cement decarbonization. A similar project in Kern County, California, exploring low-emissions cement made with clay, lost its funding as well.
The cancellations stunned local communities, many of them staunchly Republican. “This was going to be a demonstration project for the entire country,” said Don Caudell, the Republican mayor of Mitchell, adding that residents feel “stabbed in the back” after years of preparation and millions already invested. The plant was expected to generate 1,000 construction jobs and dozens of long-term positions.
Cement accounts for nearly 8 percent of global greenhouse gas emissions, and demand for cleaner alternatives is surging. States and international buyers are requiring low-carbon cement, while tech giants such as Amazon, Google, Meta, and Microsoft are seeking greener construction materials to meet their climate pledges. Industry groups warn that without federal support, U.S. companies risk falling behind China and Europe, where governments are investing heavily in next-generation cement.
“There is a growing international demand for this,” said Sean O’Neill, vice president at the American Cement Association. “The U.S. should lead in meeting that demand, rather than watching other countries take the market.”
Trump officials dismissed the projects as economically unsound, with Energy Secretary Chris Wright reiterating the administration’s view that global warming is an “exaggerated problem.” But critics — including Republicans in affected states — argue that the decision undermines both economic growth and America’s competitive edge.
The industry now faces a stark contradiction: companies eager to embrace cleaner technologies to secure their future, while a potential Trump White House signals open hostility to such efforts. For cement producers in deep-red states, the clash is exposing the risks of relying on an administration unwilling to support the very innovations they need to survive in a rapidly changing global market.
