BOEING'S -FLEET- BIOFUELS : 2030

Boeing's fleet to fly on 100% biofuel by 2030. The US company aims to slash carbon emissions in half by 2050 at broader level.

Seattle : Boeing company said it will begin delivering  commercial airplanes  capable of flying on 100% biofuel by the end of the decade, calling reducing environmental damage from fossil fuels the  ''challenge of our lifetime.''

Boeing's goal - which requires advances to jet systems, raising fuel-blending requirements, and safety certification by global regulators - is central to a broader industry target of slashing carbon emissions in half by 2050, the US planemaker said.

''It is a tremendous challenge, it is the challenge of our lifetime,'' Boeing Director of Sustainability Strategy Sean Hewsum told Reuters. ''Aviation is committed to doing its part to reduce the carbon footprint.''

Commercial flying currently accounts for about 2% of carbon emissions, according to data cited by the AirTransport Action GHroup [ATAC].

Boeing essentially has just a decade to reach its target because jetliners that enter service in 2030 will typically stay in service through 2050.

The world's largest aerospace company must also confront the task hobbled by the coronavirus pandemic and the 20-month grounding of its best-selling jet liner after fatal crashes, which has strained its finances and engineering resources.

Boeing is not starting from scratch. In 2018, it staged the world's first commercial flight using 100% biofuel on a FedEx Corp 777 freighter.

Boeing and Airbus SE also work on reducing carbon emissions through weight and drag reduction on new aircraft. [Reuters]
