Boeing made headlines last June, when its new 747-8 Freighter crossed the Atlantic Ocean running partially on biofuel. Yesterday, one of the company's 787 Dreamliners set a similar milestone – it crossed the Pacific Ocean using a biofuel mix. It was not only the first time that such fuel has been used in a 787, but also marked the first biofuel-powered aircraft crossing of the Pacific.

The fuel was derived mainly from used cooking oil, and was used in conjunction with regular jet fuel – Boeing hasn’t stated what the proportion was.

The aircraft, owned and operated by Japan’s All Nippon Airways, made a delivery flight from Boeing's Delivery Center in Everett, Washington to Tokyo’s Haneda Airport. In doing so, it is estimated that it produced approximately 30% less emissions than a similarly-sized conventional aircraft. About 10% of that reduction is said to be due to the fuel choice, with the other 20% attributed to the aircraft’s energy-efficient features, which include a body made from lightweight carbon fiber composite material.
