United’s Sustainable Flight Fund invests in DAC company Heirloom
February 26, 2025
United Airlines has announced that its UAV Sustainable Flight Fund has invested in Heirloom, a direct air capture (DAC) company, further expanding its portfolio of decarbonisation strategies.
The fund has secured an agreement granting the right to purchase up to 500,000 tons of carbon dioxide removal (CDR), which can be used for sustainable aviation fuel production or permanently stored underground.
Heirloom’s scalable technology enhances the natural ability of limestone to capture CO2 directly from the atmosphere, offering a potentially cost-effective solution for carbon removal.
“Carbon capture is one of our country’s fastest growing, energy enabling pathways,” said Andrew Chang, head of United Airlines Ventures.
“At UAV, our primary focus is finding solutions for decarbonisation 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.”
“We are incredibly proud to welcome the United Sustainable Flight Fund as an investor and to work with them to scale our DAC technology,” said Shashank Samala, CEO of Heirloom.
“By utilising DAC as a dual-pronged tool that can both greatly reduce CO2 emission from aviation fuel and remove residual emissions, we are charting a true path to Net Zero aviation.”
