Airplanes are already eco-friendly when you compare to SUVs, in terms of fuel consumed per person per kilometer traveled. There's room to improve, and considering how important air travel is to the modern world, it needs to be done. If you want to reduce carbon pollution, do something about the billions of people driving around in oversized steel cages everywhere. The airlines have room to improve, but you can't travel between continents any other way in a reasonable time. Most people don't really need cars (and certainly not SUVs); they just think they do because they bought into societies that have stupidly designed themselves with too-low density and the assumption that everyone has a car.
