The airline announced the reduction in its annual sustainability report, which also highlighted how sister company Virgin Holidays is “continuing our pledge” to improve the welfare of captive whales and dolphins in resorts sold by the operator.

Virgin Atlantic has cut CO2 emissions from 5.2 million tonnes in 2007 to 4.1 million tonnes in 2016, mainly due to its new fleet of more efficient aircraft, which have also cut noise pollution levels.

The airline said it was currently “well ahead” of schedule to reach the industry carbon targets for 2020, which have been set by aviation organistation IATA.

Other initiatives include a sustainable food project designed to help improve standards for airline caterers around the world.

Craig Kreeger, chief executive of Virgin Atlantic, said: “Our investment in a cleaner, quieter fleet is well under way with the arrival of the dual-engine 787s, and an order for 12 A350s will complete the fleet transformation and offer significant carbon savings, as well as an unrivalled experience for our customers.

“Despite political and economic headwinds we remain fully committed to our sustainability programme and will continue to drive new ways to reduce carbon emissions, and promote responsible supply chain and tourism practices.”
