Restoring balance to our atmosphere
Harnessing the natural power of limestone to permanently remove billions of tons of carbon dioxide from the air.
Our Philosophy
Limestone powers affordable carbon removal
We need to remove billions of tons of CO2 from the atmosphere to prevent the worst impacts of climate change. Heirloom leverages the best of nature and engineering to permanently remove CO2 from the atmosphere.
Rocks are some of the planet's most vital carbon sinks. Limestone is an abundant and inexpensive rock that captures massive amounts of CO2 from the air over years in a process known as carbon mineralization. Heirloom’s technology accelerates this natural process to just days.
By integrating this mineralization approach into a Direct Air Capture facility – a highly-scalable carbon removal technology which verifiably removes CO2 from the atmosphere – we get the best of both worlds: an inexpensive, high-quality, scalable carbon removal solution.
Our Facility
America’s leading Direct Air Capture company
America is leading the world in deploying DAC and Heirloom is leading America in that effort by rapidly scaling our technology around the country. We’re building two Direct Air Capture (DAC) facilities in Northwestern Louisiana with a combined yearly CO2 capture capacity of nearly 320,000 tons. This landmark investment in the state is powering the Gulf Coast's leadership in a new energy economy and further cementing America as a leader in deploying DAC technologies.
This builds on Heirloom’s leadership role in establishing America’s first commercial DAC facility in the Central Valley of California. This facility is actively removing CO2 from the atmosphere, fulfilling customer carbon removal purchases.
All of our facilities are powered by 100% additional renewable energy, constructed with strong labor protections, and pioneering a model of community governance for a new energy economy.

Heirloom’s Direct Air Capture facilities in Louisiana
Heirloom's two Direct Air Capture facilities will power the Gulf Coast's leadership in DAC technologies and advance American leadership in meeting net-zero goals.
Our Attributes
Setting the gold standard for carbon removal
1.
Verifiable
Each removal credit reflects exactly one ton of CO2 that has been permanently removed from the atmosphere, and is guaranteed by a third party that independently monitors our technology.
2.
Permanent
CO2 is permanently and safely stored underground, preventing it from reentering the atmosphere and creating harmful climate impacts.
3.
Low-cost
Our facilities are designed to be one of the lowest-cost approaches to permanent carbon removal - driven by the abundance and inexpensiveness of limestone.
4.
Community-first
We believe carbon removal can be a powerful force for good, offering lasting climate benefits while delivering social advantages. Our facilities are part of a future-proof industry that will create high-paying jobs and drive investment in education and reskilling.
