The flight is in line with parent group Cathay Pacific’s strategy to achieve a corporate target of carbon-neutral growth from 2020, Dragonair said.

The airline’s KA859 service will takeoff from Shanghai’s Hongqiao Airport on 21 March to reach Hong Kong.

The Dragonair Airbus A330-300 powered by Rolls-Royce Trent engines will be powered by 50:50 blend of fossil-based jet fuel and bio-based jet fuel, refined from 100% used cooking oil as feedstock.

The biofuel is certified and manufactured in compliance with international standards.

Dragonair claims that the biofuel-powered flight will not require any special handling or monitoring.

In addition to being a first for Dragonair, the flight will be the first international/ regional commercial flight being operated from Mainland China using a biofuel blend.
