Because biomass sources absorb carbon dioxide while growing and can have higher energy content than fossil-based fuel, their increased efficiency and use as aviation biofuel could potentially save millions of tons of aviation greenhouse gas emissions.
Air travel currently generates approximately 2 percent of man-made carbon emissions, and the industry has set aggressive goals to lower its carbon footprint, including the use of aviation biofuel when it becomes available. Today flying is one of the most efficient forms of travel based on average aircraft load factors and fuel use per seat-mile. Because the airline industry directly generates approximately 8 percent of global GDP, it is a critical factor in regional and domestic economic growth.
