Environmental activists have again targeted the private jet terminal at Bromma Stockholm Airport, according to the available report. The summary provides no further details on the action, its operational impact or any response from the airport or terminal operator.
India is looking to turn waste cooking oil into sustainable aviation fuel, supporting its green aviation ambitions while reducing reliance on imported crude. But an inefficient, fragmented supply chain could limit the feedstock’s availability as the country prepares to introduce an SAF mandate.
A surge in fuel prices is squeezing airline margins and driving fare increases that are deterring cost-conscious economy passengers. The industry response is a sharper focus on the wealthiest travelers, with premium offerings—from caviar and champagne to Porsche transfers—underscoring a widening divide in the passenger experience.
An independent analysis by Imperial College London of an Icelandic geothermal demonstration plant concludes it could produce cost-competitive green aviation fuel under the right conditions. Syntholene says the review supports its claims about cheaper eSAF production, though the conclusion is conditional on those requirements being met.
A Cologne court found that Lufthansa’s controversial ‘Green Fares’ could lead passengers to believe they could fly without affecting CO₂ emissions, and ordered the airline to change the name. The ruling puts the carrier’s climate-related fare marketing under scrutiny.
