## About

Founded in 2016 by Donald Lake, and based in Colorado, US, Terra CO2 Technology Holdings, Inc. is a clean technology company that provides a low-carbon alternative to cement used in construction. In July 2025, Terra CO2 raised USD 125.4 million in series B funding co-led by returning investors Breakthrough Energy Ventures, GenZero, Just Climate, Eagle Materials Inc., and other unspecified investors, with participation from another returning investor CEMEX Ventures. New investors Barclays Climate Ventures, Prologis Ventures, and Siemens Financial Services, along with other unspecified investors, also participated in the round. As of July 2022, Bill Yearsley is leading the company as its President and CEO. The firm offers OPUS Supplementary Cementitious Material (SCM) which is an engineered synthetic substitute for fly ash and offers 10-25% replacement to cement and is produced without burning coal. The company will use the July 2025 funding to construct its first commercial advanced-processing facility in the Dallas-Fort Worth market, expand its offices and industrial facilities, significantly grow its team, develop more shovel-ready commercial projects, and further advance new generations of cementitious products.
