EVA Air is adding more sustainable aircraft to its existing fleet as it continues to drive its sustainability efforts.

Boeing announced that the Taipei-based carrier had finalized an order for five additional 787-9 Dreamliners, a repeat order for Boeing's super-efficient widebody jet.

The announcement from the American planemaker said EVA Air's follow-on investment in the 787 will enable the airline to reduce carbon emissions further and sustainably grow its fleet.

"Our 787 fleet has become the foundation of our carbon-neutral growth strategy, and we will continue to leverage this aeroplane's unrivalled efficiency and performance for many years to come," said Clay Sun, president of EVA Air.

"This new order supports our ongoing commitment to operate a more sustainable fleet that will enable us to reduce carbon emissions while providing our passengers with world-class service," he added.

Boeing noted that the 787-9 would provide EVA Air with increased capacity, greater range and 25% better fuel efficiency compared to earlier-generation jets.

Most efficient, sustainable fleet

EVA Air's 787 fleets has provided the airline with added flexibility on long-haul routes to North America, Europe and Asia.

"EVA Air operates one of the most efficient and sustainable widebody fleets in the world, with repeat orders for the 787 serving as a testament to the value this family of aeroplanes brings to its network," said Stan Deal, president and CEO of Boeing Commercial Airplanes.

"With additional Dreamliners, EVA Air is well positioned for growth, especially as passenger traffic returns to pre-pandemic levels in Asia," he added.

The Taipei-based airline currently operates a fleet of 10 787s, including four 787-9s and six 787-10s.

With this new order, EVA Air has unfilled orders for seven 787-10s and nine 787-9s.

EVA Air also operates one of the world's largest 777 fleets with more than 40 airplanes, including passenger and freighter models, with one 777 Freighter on order.
