Oslo airport is importing jet fuel made from waste cooking oil in California. This has invoked criticism that shipping and trucking it more than 16,000 kilometers (10,000 miles) invalidates environmental benefits.
Oslo was the first international airport hub to offer biofuels as part of the fuel mix it sells in 2016.
This was followed by Los Angeles and Stockholm, as part of efforts to limit surging greenhouse gas emissions in the airline industry.
“This is a tiny little drop (in fossil jet fuel use). But it is the first drop,” said Olav Mosvold Larsen of state-owned Avinor, which runs 45 airports in Norway. He said jet biofuels were twice the cost of conventional fuels.
In recent months, Avinor has imported waste cooking oil, from California, he said, confirming a report in the Norwegian daily Aftenposten. Last year, Oslo imported biofuels came from Spain.
Some environmentalists say that shipping biofuels from California, via the Panama Canal, makes no sense.
