ZURICH: SWISS is following the Lufthansa Cargo lead and applying a biomimetic film to the fuselage and engine nacelles of 12 B777-300ER passenger aircraft to reduce annual fuel consumption by 4,800 tonnes and subsequent CO2 emissions by 15,200 tonnes.

The ‘AeroSHARK’ coating, jointly developed by Lufthansa Technik and BASF, features millions of ‘riblets’ – small protrusions just 50 micrometres high – that replicate the hydrodynamic skin of sharks to reduce an aircraft’s aerodynamic drag.

“Reducing its environmental footprint is one of the greatest challenges ahead for the aviation sector, and being carbon-neutral in our flying by 2050 is a key SWISS strategic objective,” noted SWISS CEO Dieter Vranckx. “We put a major emphasis at SWISS on actively promoting and making targeted investments in new technologies. And we’re delighted that, in becoming the world’s first passenger airline to use the AeroSHARK technology, we’ll be making a further substantial contribution to ensuring more sustainable travel.”

SWISS has set itself the objective of halving its net CO2 emissions by 2030 from 2019 levels and making its business and operations carbon-neutral by 2050.

When its freighter programme is completed, Lufthansa Cargo says its fleet will save 3,700 tons of kerosene and just under 11,700 tons of CO2 emissions a year.
 
The airline has announced an agreement with Röhlig Logistics to offset CO2 emissions on routes between Frankfurt, Mexico City, Shanghai and HongKong. According to company managing partner Philip Herwig, 100 percent of emissions will be offset by supporting projects of the Swiss-based non-profit climate protection organisation myclimate.

Curated by Lufthansa Cargo, its programmes include wood-based biomass instead of gas boilers in Brazil and electricity from FSC-Wood Waste in the Amazon; efficient cook stoves in Nigeria, Rwanda and Burundi; biogas plants for 9,000 families in India; supporting savings groups to enable women to afford an efficient cook stove in Kenya; solar stoves in Madagascar; community reforestation in Nicaragua; and protection of forests for indigenous peoples, wildlife and the climate in Tanzania.

The amount of emissions saved from the projects is calculated and can be passed on to companies in the form of emission reduction credits. In the case of Röhlig, the four routes are expected to produce and initial 1,000 tonnes of CO2 offsets.

Meanwhile existing Lufthansa Cargo SAF customer DB Schenker has signed a purchase contract for over 2,500 tons of biofuel from CMA CGM in a bid to ensure its entire Less-than Container Load ocean volumes are CO2-free. If enough customers take up the booking option, over 7,000 tons CO2e well-to-wake will be saved, says the company.

And after successfully introducing its ‘GoGreen Plus Service’ for ocean freight, DHL Global Forwarding has now extended the offer for airfreight.

Unlike offsetting, The DHL option is based on the displacement principle: the more customers book the service, the more SAF can be purchased to reduce the CO2 emissions for a respective air or ocean freight shipment.

“Every airplane and vessel emit their exhaust gases into the same atmosphere, and it is not decisive on which route or which means of transport biofuels are used," commented Thomas Mack, global head of Air Freight at DHL Global Forwarding. “From a technological standpoint, our service is currently the simplest, most efficient and sustainable way to reduce CO2 emissions in transportation. As one of the world's leading logistics service providers, we see it as our responsibility to lead the way to greener transportation and to set a good example for others to follow.”

Earlier this month, DHL ordered 33 million litres of SAF over three years from Air France KLM Martinair Cargo.
