Twelve

Twelve is a chemical technology company based in Berkeley, California, focused on carbon transformation. Founded in 2015, the company converts carbon dioxide (CO2) into valuable chemicals, fuels, and materials that are typically derived from fossil fuels. Their mission is to create a fossil-free future by producing essential products "from air, not oil," which helps address climate change and reduce greenhouse gas emissions. Twelve utilizes metal catalysts and electrochemical reactors to transform CO2 into synthetic gas, methane, ethylene, and other hydrocarbons, including carbon-neutral fuels like E-Jet® sustainable aviation fuel. The company partners with various industries, including automotive, aviation, and household goods, to replace fossil-based inputs with CO2-derived alternatives. Notable partners include Mercedes-Benz, Procter & Gamble, and NASA.
