Aviation jet fuel derived from fossil fuels is a type of kerosene (a
distilled petroleum product invented by a Canadian). While the fuel
burns quite efficiently compared to other fossil-based transportation
fuels, it is still responsible for GHG emissions (approximately 2% of
global emissions). Great advances are being made in the move toward a
carbon-neutral aviation fuel, with ongoing tests of aviation biofuels
made from fast-growing, non-food sources such as algae and jatropha.
The Air Transport Action Group (ATAG) has a primer on aviation biofuels on the Enviro.Aero site.
The IATA 2008 Report on Alternative Fuels provides more specific information on the advances that have been made.
