The aviation sector is responsible for roughly two percent of global carbon dioxide emissions. If current trends continue, its share of the total is expected to grow substantially in coming decades. Fortunately, in recent years a number of airlines have made concerted efforts to make flying more environmentally sustainable. Most of the solutions to date have involved biofuels made from plant-based compounds. But Virgin Atlantic took a different approach, partnering with the U.S.-based company LanzaTech that was developing a technology to turn industrial pollution into jet fuel.

On October 2nd, the partnership achieved a major milestone: the first passenger flight powered (in part) by the innovative new fuel. There was plenty of fanfare around the flight, which we were on hand to cover. And though the flight was one incremental step out of many required to make the tech mainstream, it was still a milestone worth celebrating. Read on for our full coverage of the announcement, press conference, and the flight itself — including a surprise appearance by Sir Richard Branson!
