On a long sector such as Los Angeles to Hong Kong the 747-400 uses 160K kilograms of fuel carrying 400 passengers over the 12000 kilometers. The fuel used is kerosene. >From memory, assuming 4 people to a car a fleet of 100 cars carrying the same 400 people over the same distance would use more fuel. Your figures appear to me to be pessimistic but I would be interested in your final conclusions. Info on emissions can be obtained from Rolls-Royce, Pratt & Whitney or General Electric. There is currently a lot of pressure and competition to produce clean burn engines as environmental concerns and future emissions legislation are now a factor in an airline's engine selection procedure.
