Aviation accounts for almost 3 percent of carbon dioxide emissions, according to data from the Federal Aviation Administration from 2005, so finding a way to reduce those emissions became an important goal for NASA and the aviation industry. With this in mind, NASA created the CAFE Green Flight Challenge, a competition to test fuel-efficient aircraft designs, in which the winner, Pipistrel-USA.com of State College, PA. was awarded $1.35 million from NASA. The second place team of eGenius of Ramona, Calif. was awarded $120,000.
