As per ESG Today, Twelve specializes in manufacturing synthetic aviation fuels known as e-SAF, made from CO2, water, using renewable power. The company, founded back in 2015 in California, produces fuels and chemicals from captured CO2 emissions, rather than fossil fuels, making its products more sustainable.

Compared to regular kerosene, Twelve's SAF offering reduces lifecycle emissions of the fuel by as much as 90%.

Nicholas Flanders, Twelve’s Co-Founder and CEO said that "our power-to-liquid E-Jet fuel offers industry-leading emissions reduction potential with the added benefits of an abundant feedstock supply and significantly smaller land and water footprints compared to alternative SAF pathways."

Over 14 years, Twelve will supply 984 million liters of SAF to IAG's five European airlines, among which is British Airways and initial deliveries will take place throughout 2025. The two companies started collaborating in 2020, when Twelve joined IAG's Hangar 51 startup accelerator program to commercialize the e-SAF maker's technology.

Luis Gallego, IAG’s CEO said that "we have a roadmap to achieve net zero by 2050 including a target to fly with 10% Sustainable Aviation Fuel by 2030. The shortage of sustainable fuel globally continues to be a problem for our industry although innovative companies like Twelve are an important part of the solution."
