Senior Administrative Assistant Long , CA

Today's aircraft contribute around 4% of global CO2 emissions, equivalent to the emissions of 200 million cars. This is only going to increase:
Air travel is forecasted to double by 2050, while meaningful efficiency gains using current airplanes have hit a wall.

Jet Zero is developing a blended-wing body (BWB) aircraft. It uses up to 50% less fuel and will be built to accommodate zero‑emission hydrogen propulsion. Jet Zero is the inevitable solution to sustainable air travel.

We are experienced aerospace professionals and engineers, excited about the future. That future will only be possible if we share our vision and what it means to people’s lives: carbon‑free flight that is better for both passengers and airlines around the world.
