Restoring Balance to Our Atmosphere

Heirloom is a pioneering company dedicated to mitigating the severe impacts of climate change by developing and deploying highly cost-effective Direct Air Capture (DAC) technology. The company leverages the natural power of limestone, an abundant and inexpensive rock, to permanently remove billions of tons of carbon dioxide from the atmosphere. Heirloom's innovative technology significantly accelerates the natural carbon mineralization process, reducing the time it takes for limestone to absorb CO2 from years to mere days.

Heirloom integrates this accelerated mineralization approach into scalable DAC facilities, offering a verifiable, permanent, and low-cost solution for carbon removal. The company established North America's first commercial DAC facility in California's Central Valley, which is actively removing CO2 and fulfilling customer carbon removal purchases. Furthermore, Heirloom is expanding its operations with two additional DAC facilities in Northwestern Louisiana, projected to capture nearly 320,000 tons of CO2 annually.

These facilities are powered by 100% additional renewable energy, built with strong labor protections, and designed with a community-first governance model, contributing to a new energy economy and cementing America's leadership in DAC technologies. Heirloom serves major global buyers of carbon removal credits, including leading technology and financial firms, partnering with them on the path to a carbon-negative future.
