Will Sustainable Aviation Ever Take Off?

For those of us who love to travel, climate guilt weighs heavily. Civil aviation accounts for about 3% of global greenhouse gas emissions, and that number is going up.

Sustainable aviation fuels, or SAFs, hold the most promise, as they can theoretically drop right into existing engines and infrastructure. Beyond that, a number of startups are tinkering with electric battery-powered aircraft, as well as hydrogen-powered electric planes. But how sustainable are these options, and are they really ready for prime time?  Guests: Fred Ghatala, Director of Carbon & Sustainability, Advanced Biofuels Canada  Stephanie Searle, Fuels Program Director, ICCT Scott Cary, Project Manager, NREL  Christina Beckman, Co-creator, Tomorrow’s Air; Vice President, Adventure Travel Trade Association Learn more about your ad choices.
