$124.5M Series B funding secured from major investors including Barclays, Breakthrough Energy Ventures, and Siemens Financial Services to scale sustainable cement production.
First commercial facility planned in Dallas-Fort Worth to produce 240,000 tons per year of Terra’s low-carbon Supplementary Cementitious Materials (SCMs).
OPUS products positioned for immediate deployment using local feedstocks and existing infrastructure—delivering cost and performance advantages without relying on subsidies.
Terra CO2, a U.S.-based low-carbon building materials company, announced it has secured $124.5 million in Series B funding to scale its commercial production of sustainable cement alternatives. The round was co-led by Breakthrough Energy Ventures, Eagle Materials, GenZero, and Just Climate, with new backing from Barclays Climate Ventures, and strategic investment from Prologis, Cemex, and Siemens Financial Services. The company also secured a credit facility co-led by Silicon Valley Bank (First Citizens Bank) and Stifel Bank, enhancing financial flexibility.
This funding will accelerate the launch of Terra’s first commercial-scale advanced-processing facility in the Dallas-Fort Worth area, with a planned capacity of 240,000 tons per year. The capital will also support expansion of Terra’s offices and industrial operations, staffing, and further development of new-generation cementitious products.
“Terra’s mandate is to deliver cementitious material solutions that the market would purchase solely based on cost and performance, even if there was no carbon benefit,” said Terra CEO Bill Yearsley. “The fact that Terra’s cementitious materials also offer significant carbon mitigation is an additional advantage for the built environment.”
Amid declining U.S. subsidies for climate initiatives, Terra’s business model offers a subsidy-independent, commercially ready solution. Its Supplementary Cementitious Materials (SCMs) offer a cost-effective, high-performance alternative to Portland Cement and declining resources like fly ash.

Terra’s SCMs are manufactured through its proprietary OPUS process, which uses abundant, inexpensive local materials from aggregate mines, operating seamlessly within existing cement infrastructure. This enables rapid, scalable deployment without the need for major retrofits or supply chain changes.
“Terra’s technology offers a combination of commercial readiness and cost competitiveness,” said Steven Poulter, Head of Barclays Climate Ventures. “Its ability to support the decarbonization of a heavy industry such as cement aligns with our commitment to support scalable, near-term solutions in hard-to-abate sectors.”
Terra’s second product, OPUS Zero, is currently undergoing active concrete trials and is designed to fully replace traditional Portland cement, further positioning the company as a key player in the decarbonization of the construction industry.
