When it comes to minimizing carbon footprints, airlines have yet to make any significant impact. The world is changing, with technology making a difference in this realm. ZeroAvia and its forward-thinking model are gaining attention from some well-known investors, including Bill Gates, Amazon, and Shell. It’s also partnering with British Airways. Other airlines are excited as well, with the company’s CEO saying that “more than 10 airlines are preparing to transition to hydrogen fuel by 2023.”
