Long-haul carrier Emirates test flies Boeing 777 on sustainable fuel

Long-haul carrier Emirates successfully flew a Boeing 777 on a test flight Monday with one engine entirely powered by so-called sustainable aviation fuel. This comes as carriers worldwide try to lessen their carbon footprint.

Flight No. EK2646 flew for just under an hour over the coastline of the United Arab Emirates, after taking off from Dubai International Airport, the world’s busiest for international travel, and heading out into the Persian Gulf before circling back to land.

The fuel powered one of Boeing’s two General Electric Co. engines, with the other running on conventional jet fuel for safety.

This flight is a milestone moment for Emirates and a positive step for our industry as we work collectively to address one of our biggest challenges reducing our carbon footprint,”
