Swedish tech helps Norwegian cut CO2

Using wind and temperature data, the airline says it can save 5,000 tonnes of fuel a year and reduce emissions by 16,000 tonnes.

Norwegian says it is adopting new technology that cuts CO2 emissions by 16,000 tons per year. Following a successful test project, the carrier will expand its cooperation with Avtech Sweden to further reduce fuel consumption.

A report by the Swedish Energy Agency, which partly financed the project, shows that fuel consumption was reduced by 22 kilos per flight during the test project.

This equals an annual CO2 reduction of 16,000 tons, or 5,000 tons of fuel per year – which in turn leads to reduced costs for Norwegian.

The new technology, called Aventus Air weather service, provides pilots with “highly accurate” wind and temperature information in accordance with their flight plan.

That data is transferred to the aircraft’s systems, which makes it possible to optimise the flight path for improved fuel efficiency and reduced emissions.

The Swedish Energy Agency has published a report on the test project, in which data from a total of 29,000 flights completed in November and December 2017 are analysed. The results show a reduction of 640 tons of fuel on Norwegian’s flights during this period.

Before biofuel
Norwegian makes the point that reduced fuel consumption is crucial to reducing emissions and that in anticipation of biofuel becoming commercially available and manufactured on a large scale, new aircraft are the most important measure an airline can take to cut emissions.

“We have one of the youngest and most environmentally friendly fleets in the world, which has enabled us to reduce emissions by more than 30% since 2008,” claims Tomas Hesthammer, Norwegian’s director of flight operations.

“Our ambition is to continue to reduce emissions per passenger with fuel-efficient aircraft and with innovative technology. The Avtech project demonstrates that fuel consumption can be further reduced by using advanced weather data.”

Norwegian was recently named the most fuel-efficient transatlantic airline by the International Council on Clean Transportation, whose analysis shows that the carrier has a fuel consumption of 44 passenger kilometres per litre, which is 33% more efficient than the industry average.
