Cement Producers Target Carbon Footprint with Portland-Limestone Cement

October 7, 2020, WASHINGTON, D.C. – The Portland Cement Association (PCA), representing America’s Cement Manufacturers, launched a new promotion initiative today emphasizing the sustainable benefits of portland-limestone cement (PLC). PLC, engineered with more limestone, performs comparably to Type I portland cement with up to 10% less greenhouse gas emissions.

Launched today is the microsite, focused on the product, featuring case studies, applications, frequently asked questions and the status of acceptance in the United States and around the world. Additionally, the site gives users access to a PLC calculator where builders, architects and designers can input building size or pavement length to see how much PLC can reduce a project’s overall carbon footprint.

“PLC is another example of the cement industry evolving over the years, continuing to innovate and sustainably producing the high-quality cement that is needed to help keep America’s infrastructure strong and resilient,” said PCA President and CEO Mike Ireland. “This initiative will help educate engineers and other specifiers on how PLC can easily be incorporated into numerous projects.”
