What is CarbonBuilt?
Based in Los Angeles, CarbonBuilt operates at the intersection of material science and industrial decarbonization. The company has engineered a transformative process that enables the injection of carbon dioxide emissions—captured from power plants and industrial facilities—directly into concrete mixtures. By mineralizing CO2 within the building material, CarbonBuilt effectively turns concrete into a carbon sink, offering a scalable alternative to conventional, high-emission construction materials. This approach not only mitigates the environmental impact of the built environment but also provides a viable pathway for industrial emitters to repurpose their waste streams into high-value, sustainable infrastructure components.
How much funding has CarbonBuilt raised?
CarbonBuilt has raised a total of $10M across 1 funding round:
Series A
$10M
Series A (2021): $10M with participation from Grantham Environmental Trust's Neglected Climate Opportunities, Tony Pritzker, Lime Street Ventures, and Climate Capital
Key Investors in CarbonBuilt
Lime Street Ventures
A venture capital firm focused on early-stage technology and life science companies, primarily within the Boston and Cambridge innovation ecosystems.
Climate Capital
An investment firm specializing in renewable energy projects and sustainable infrastructure, managing assets that drive decarbonization and capital growth.
Grantham Environmental Trust's Neglected Climate Opportunities
An investment vehicle dedicated to identifying and supporting high-impact climate solutions that are often overlooked by traditional venture markets.
What's next for CarbonBuilt?
Following this major enterprise-level funding, CarbonBuilt is expected to accelerate the commercial deployment of its carbon-sequestration technology. The strategic capital will likely be directed toward expanding manufacturing partnerships and optimizing the integration of its CO2-injection systems into existing concrete production facilities. As the global regulatory landscape shifts toward stricter carbon reporting and net-zero mandates, CarbonBuilt is positioned to become a critical player in the supply chain for green building materials. Future growth will likely focus on scaling operational capacity to meet the rising demand for low-carbon construction solutions in both public and private sector projects.
