In fact, airlines around the world have committed to carbon-neutral growth beginning in 2021. As part of that commitment, U.S. airlines have set a goal to reduce carbon dioxide emissions by 50 percent by 2050 compared to 2005 levels.
Reaching that goal will not be easy. Electric planes won’t make much of a dent because the batteries can only power the smallest of light planes. The only way to achieve emission reduction goals is with liquid fuels that have a lower carbon footprint: Sustainable Aviation Fuels (SAF).
Pacific Northwest National Laboratory’s John Holladay co-authored a recent report that presents a pathway to low-cost, clean-burning, and low-soot-producing jet fuel.
