Terra CO2 has raised $82 million in Series B funding to accelerate the commercial deployment of its low-carbon cement technology across North America and Europe. The funding round was co-led by Just Climate, Eagle Materials, and GenZero, with continued support from Breakthrough Energy Ventures and additional industrial partners expected to join.
The investment will support Terra’s expansion, including multiple full-scale production facilities in North America and early-stage development in Europe. The company is set to break ground on its first commercial plant in Texas, with construction led by Clark Construction.
Cement production accounts for approximately 8% of global CO₂ emissions, making it one of the most challenging sectors to decarbonise. Terra’s OPUS technology offers a scalable alternative, using abundant raw materials from existing mines to produce cementitious materials that integrate seamlessly into current infrastructure. The technology enables immediate emissions reductions without requiring major industry overhauls.
“Securing backing from leading climate funds and industry partners validates our approach to large-scale cement decarbonisation,” said Bill Yearsley, CEO of Terra CO2. “This funding allows us to expand our operations across North America and establish a foothold in Europe.”
The funding comes amid growing demand for sustainable construction materials, especially as supplies of traditional Supplementary Cementitious Materials (SCMs), such as fly ash, decline.
“As demand for cement continues to rise, developing alternative SCMs is critical,” said Michael Haack, president and CEO of Eagle Materials. “This investment aligns with our goal of finding sustainable, commercially viable solutions that work within existing infrastructure.”
Terra has already secured agreements for its first facility in Dallas-Fort Worth with Asher Materials and has partnered with Eagle Materials for multiple 240,000-ton plants across North America. The company’s technology has been extensively tested in commercial applications, including the construction of a Porsche dealership in Houston.
A recent $52.6 million grant from the U.S. Department of Energy will support a second commercial plant, further expanding Terra’s capacity to meet industry needs. “Terra’s technology offers a practical, cost-competitive solution to one of the most emission-intensive industries,” said Benoit Grobon, managing director at Just Climate. “Their strategic deployment approach positions them to drive meaningful carbon reductions in construction.”
