Airlines eye approved biofuels by 2011
Recent tests by Continental Airlines, Japan's JAL, Air New Zealand and Virgin had shown that next generation sustainable clean burning biofuels were successful, IATA director general Giovanni Bisignani says.
Biofuels would still need to be produced in commercially viable quantities with common quality standards, and suppliers worldwide would also need to be equipped for storage.
US aircraft maker Boeing estimates that biofuel blends with jet fuel could cut emissions by 50% without the need to change aircraft.
Certification is widely regarded as a first technical step that could eliminate some of the investment uncertainties that cloud the use of high quality biofuels in aviation.
