Well we never. A plane has actually flown on fuel made using plants grown in the United Arab Emirates.
Etihad Airways has celebrated a major milestone in developing a comprehensive, sustainable aviation fuel with Khalifa University, and the Boeing 787 flight from Abu Dhabi to Amsterdam has been hailed a success.
It was the first time a flight has been operated on fuel derived from plants grown in saltwater, but extensive research has shown that it is possible and safe for jet fuel to be produced using desert, land and sea water through an innovative agricultural process. And put simply, this means alternative aviation fuel to reduce carbon emissions.
His Excellency Dr Thani bin Ahmed Al Zeyoudi, Minister of Climate Change and Environment, adds, “The UAE’s visionary leadership is strongly committed to positioning the country as a global hub for sustainability."
"Clean, alternative aviation fuels are an innovative solution to significantly reducing harmful carbon emissions. The UAE is proud to be a pioneer in this domain."
Sustainable fuel for the flight - which is blended directly with jet fuel - was derived from oil in Salicornia plants, which were grown in Masdar City near Abu Dhabi International Airport.
Approximately 160,000 passenger flights have flown on a blend of sustainable and traditional jet fuel since the first biofuels were certified for commercial use in 2011. Sustainable aviation fuel represents a significant opportunity to help aviation meet its goals to cap the growth of carbon emissions by 2020 - and to cut levels to half of what they were in 2005 by 2050. This is a project that sounds pretty fly to us.
