Report: 'Green' flight route emits more CO2 than fossil fuel

New report shows that Norwegian's new domestic route with biofuel emits more CO2 than regular jet fuel.

Last week it was announced that Norwegian had been awarded the tender for Denmark's first green domestic route, which will be from Aalborg Airport to Copenhagen. The route, which is expected to take off on 1 March 2026, was presented as "a historic step for Danish aviation."

- Throughout the entire process, we have worked to ensure that the green domestic route would be as green as possible and start as quickly as possible.   Now two of Denmark's largest airports will be connected by a route where as much green aviation fuel as possible is used on each aircraft. This can hopefully help pave the way for more airlines to use more green aviation fuel in the future, said Transport Minister Thomas Danielsen (V) in connection with the announcement.

But now a new report casts doubt on how green the flight route really is, as biofuels worldwide emit 16 percent more CO2 than the fossil fuels they replace.

The report, commissioned by the environmental organization Transport & Environment and prepared by the British consultancy Cerulogy, indicates that 90 percent of the sustainable fuel produced today comes from crops. This is reported by Politiken. "Burning crops as fuel only pushes us further in the wrong direction," says Cian Delaney, campaign manager for biofuels at the organization, in a press release.

According to Professor Jannick Schmidt from Aalborg University, this means that the planned green domestic route between Aalborg and Copenhagen will in fact emit more CO2 than fossil fuels. "In its current form, the route is a really bad idea that wastes a lot of money on a solution that cannot be scaled," he writes in an email to the media. Instead, the funds should be invested in the production of Power-to-X fuels based on renewable energy from the sun and wind.

However, Transport Minister Thomas Danielsen (V) defends the project and calls biofuel "a step on the way", while emphasizing that the long-term goal is jet fuel produced with Power-to-X: "But instead of waiting to do anything, we are now establishing a green airport terminal for those who want to refuel green, and a tender system that supports the rollout," the minister adds.
