United Airlines Ventures invests in direct air capture company Heirloom

In Illinois, United recently announced that the UAV Sustainable Flight Fund has made an investment in direct air capture (DAC) company Heirloom, adding Heirloom’s measurable, quantifiable carbon reduction technology to its already robust portfolio of decarbonization strategies. The Fund also entered into an agreement for the right to purchase up to 500,000 tons of carbon dioxide removal (CDR) to be delivered for the production of sustainable aviation fuel or permanently stored underground.

Heirloom’s already-proven and scalable technology accelerates the natural power of limestone to capture CO2 directly from the air – making it potentially one of the lowest cost pathways for removing carbon dioxide.
