United announced that the United Airlines Ventures (UAV) Sustainable Flight Fund has invested in direct air capture (DAC) company Heirloom, enhancing its portfolio of decarbonization strategies with Heirloom’s effective carbon reduction technology.
Heirloom’s Revolutionary Carbon Capture Technology
Heirloom specializes in direct air capture (DAC) technology for the extraction of atmospheric carbon dioxide. Heirloom’s affordable and scalable solution harnesses the natural energy of limestone to directly extract CO2 from the air. Heirloom’s product is among the lowest-cost methods of CO2 removal, a practical solution to the problem of climate change.
Andrew Chang, head of United Airlines Ventures, said, “Carbon capture is one of our country’s fastest growing, energy enabling pathways.”
He added, “At UAV, our primary focus is finding solutions for decarbonization that are profitable. Heirloom’s technology aligns directly with this objective, offering a scalable and commercially viable approach and complements United’s commitment to net zero by 2050.”
Agreement to Purchase Carbon Removal
Besides the investment, UAV has entered an agreement with an option to purchase up to 500,000 tons of carbon dioxide removal (CDR) from Heirloom. The carbon credits will either store the CO2 underground permanently or create sustainable aviation fuel. The alliance forms part of United’s broader goals for sustainable aviation and growth that is carbon-neutral.
Shashank Samala, Heirloom CEO, said he was pleased to have the United Sustainable Flight Fund on board as an investor and noted the potential to partner on growing their DAC technology. He pointed out that by applying DAC as a two-way tool to drastically lower CO2 emissions from aviation fuel and eliminate leftover emissions, they are leading the way for Net Zero aviation.

United’s Continual Investment in Carbon Capture
United has made Heirloom its third carbon capture investment and its first in a company commercializing direct air capture technology. Additionally, investments by the airline in direct air capture and point-source solutions play a central role in addressing the carbon footprint of aviation.
Direct air capture directly captures CO2 from the air, as opposed to point-source capture, and thus is critical in emissions reduction.
