The ticket seller Green Airlines operated the last charter flights between Paderborn and Westerland at the weekend - at least for the time being. Embraer Phenom 300 business jets from Pad Aviation were used as "environmentally friendly aircraft". Demand on this route was not particularly great, as the ticket agent was rarely able to persuade more than a single-digit number of travelers to buy tickets per flight. Recently, individual legs were no longer operated at all. The aircraft was positioned all over Europe, which was not exactly environmentally friendly. According to Naturefund, Green Airlines has only donated 60 trees so far. In mid-August 2021, according to a report by Airliners.de, there were 52 trees, so the funds provided to the environmental project are likely to be very limited. Misleadingly, the ticket agent does not link to its own donations to Naturefund on its homepage, but to the overall project. If you consider that the cost of tree donations is in the cent range and you multiply this by 60, the total is a small amount. In any case, the many positioning flights criss-crossing Europe are by no means "compensated". Naturefund provides information at this link on how many trees "Green Airlines" has actually donated. From February 2022, Green Airlines plans to offer charter flights from Weeze and Karlsruhe/Baden-Baden. It remains to be seen whether this will actually be accepted. The carrier's last expansion step ended in a fiasco, with the airline strictly refusing to pay affected passengers compensation in accordance with the Air Passenger Rights Regulation.
