Restoring balance to our atmosphere
Leveraging the natural power of limestone to remove 1 billion tons of C02 by 2035 using the world’s most cost-effective Direct Air Capture technology.
Our Philosophy
Our planet
knows best
Rocks are some of the planet's most vital carbon sinks. Over geological timescales, CO2 from the atmosphere binds to minerals and permanently turns to rock – a process known as carbon mineralization.
Limestone is one of the most abundant rocks on the planet, capturing massive amounts of CO2 from the air over years. Heirloom’s technology accelerates this natural process to just days.
We’ve combined the best of engineering and nature, to develop the most affordable and scalable Direct Air Capture technology in the world. We offer the highest quality carbon removal credits available for purchase today.
Our Facility
The first commercial Direct Air Capture facility in the United States
Heirloom is operating the first DAC facility in the United States to permanently remove CO2 from the atmosphere, fulfilling customer carbon removal purchases in Tracy, California. The facility is fully powered by renewable energy, constructed with local union labor, and built in partnership with the City of Tracy and will pioneer a community governance model in the year ahead.
We are actively capturing atmospheric CO2, which is permanently sequestered in concrete through a partnership with CarbonCure Technologies.

A CO2 removal facility that is rapidly and principally deployed
Our first commercial facility demonstrates our rapid technology and business progress since our founding in 2020. We are operating this facility consistent with our recently-outlined principles for the responsible deployment of carbon removal.

Partners on the path to a carbon negative future
Our approach
The highest-quality carbon removal credits
1.
Permanent removal of CO2
Our CO2 is permanently and safely stored underground, or in building materials like concrete.
2.
Minimal environmental footprint
Our facilities can remove 50 tons of CO2 per square meter and can be sited on non-arable land.
3.
Creating high-paying green jobs
We will site our facilities in fossil energy communities, providing high-paying jobs and driving investment in education and reskilling in a future-proof industry.
4.
Designed for affordability
Our carbon removal credits will cost less than $100 per ton of CO2 by 2035.
