Concrete Industry Working Toward Carbon Elimination

By Lucy Perry CEG CORRESPONDENT

Marking a year of progress toward its goal of carbon neutrality, the Portland Cement Association (PCA) last fall noted the multiple pilot projects across the United States that have showcased emerging technologies to capture and reuse or store carbon. Those projects are tools to gauge success as the industry moves toward eliminating all carbon in concrete by the year 2050.

“I’m proud that our industry is taking this on,” said Mike Ireland, president and CEO of PCA. “Together we’ve made progress on a bold, yet achievable pathway to carbon neutrality.”

Ireland noted the industry is “creating a win-win scenario to meet demand for durable infrastructure that also has a low carbon footprint, which will result in a more sustainable and resilient world for the next generation.”

The industry’s “unified approach” to decarbonization is the central focus of the PCA’s Roadmap to Carbon Neutrality.

With the demand for infrastructure never greater, it’s vital for the built environment to advance in a fashion that is sustainable and climate adapted, said the PCA.

“This need spotlights the importance of the progress PCA— representingAmerica’s cement manufacturers — has made on its efforts to reduce emissions.”

In the first year, the campaign saw multiple U.S. cement manufacturers working with the Department of Energy to implement pilot programs around the concept of carbon capture, utilization and storage (CCUS).

The association reported increased acceptance and use of Portland limestone cement (PLC), a product that reduces concrete’s carbon footprint by approximately 10 percent.

“In addition to private building projects, PLC has been approved by 44 state departments of transportation, some of the largest consumers of cement,” noted PCA.

Consumer demand for sustainable concrete is growing, and companies are specifying low-carbon materials for major construction projects.

“Through this Roadmap, we are creating a built environment that is durable and also sustainable,” said Ron Henley, president, GCC of America, and chairman, PCA. “We are demonstrating that the cement and concrete industry can address climate change, reduce greenhouse gases and eliminate barriers restricting environmental progress.”

In fact, the industry is pushing innovation and calling on stakeholders for more collaboration, according to PCA. The association is working with Congress and federal agencies to maximize the benefits of both the IIJA and the IRA.

Both policies, it noted, provide significant funding for the clean technologies the cement industry requires to reduce emissions.

PCAalso wants to see existing legislation, see CARBON page 52
