Today, Cemvita Corporation announced an off take arrangement with United Airlines for up to 1 billion gallons of sustainableaviation fuel (SAF) from Cemvita’s first full-scale SAF plant. Under the agreement, signed by Cemvita and United Airlines, Cemvita will supply United Airlines up to 50 million gallons annually for 20 years of Sustainable Aviation Fuel (SAF) made from CO2. “Since our initial investment last year, Cemvita has made outstanding progress, including opening their new pilot plant – an important step towards producing sustainable aviation fuel,” said United Airlines Ventures President Michael Leskinen. “United is the global aviation leader in SAF production investment, but we face a real shortage of available fuel and producers. Cemvita’s technology represents a path forward for a potentially significant supply of SAF and it’s our hope that this offtake agreement for up to one billion gallons is just the beginning of our collaboration.” Game Changing Technologies: Commercialized SAF is currently made from used cooking oil and agricultural waste. Cemvita's technology has the potential to provide more reliable feedstock production with minimal land, water, and electricity needs. Furthermore, the output of eCO2 plants has the potential to be carbon-negative and Cemvita is aiming to be cost competitive with existing crop based HEFA feedstocks and fuels, which is a crucial factor for the successful adoption of any new biomanufacturing process. “Biology is capable of truly amazing things,”said Moji Karimi, CEO of Cemvita. “Our team of passionate,pioneering, and persistent scientists and engineers are on a mission to create sustainable BioSolutions that redefine possibilities.” “We are thrilled to partner with United Airlines in working towards transforming the aviation industry and accelerating the energy transition,” Moji continued. “This agreement featuring our unique SAF platform is a major milestone towards demonstrating our journey to full commercialization.” United has aggressively pursued strategic investments in SAF producers and revolutionary technologies, including carbon capture, hydrogen-electric engines, electric regional aircraft, and air taxis.This year, United launched its UAV Sustainable Flight Fund^SM, a first-of-its-kind investment vehicle that is designed to leverage support from cross-industry businesses to support start-ups focused on decarbonizing air travel through SAF research, technology, and production. Cemvita was announced as part of the fund’s inaugural group of portfolio companies. United has invested in more SAF production than any other airline globally.^1 1 Based on publicly announced airline offtake agreements for future purchases of SAF.  United's Commitment toNet Zero Emissions by 2050 United was the first airline to commit to net zero carbon emissions by 2050, without relying on traditional carbon offsets.In addition to the UAV Sustainable Flight Fund^SM, United has launched a SAF purchasing program called the Eco-Skies Alliance and established a venture fund - United Airlines Ventures - to identify and invest in companies and technologies that can decarbonize air travel. These strategic investments include carbon capture, hydrogen-electric engines, electric regional aircraft and air taxis. About United Airlines At United, Good Leads The Way.
