While airlines have much work to do yet, these seven carriers have introduced an array of sustainability measures including the early adoption of alternative-fuel technology, plastic and food waste-reduction programs, eco-friendly materials, and more.
Most sustainability experts will scoff at the idea of “sustainable” and “airlines” in the same sentence. “Today, at this moment, it’s not yet realistic to fly fully sustainably,” says Pedro Piris-Cabezas, a global transportation expert and economist at the nonprofit Environmental Defense Fund.
“Airlines’ ‘green claims’ are often multiplying more quickly than their fact-checking departments care to back up with substantive evidence,” he says. Zheng concurs, adding, “Until we see actual decarbonization happen and have the rate of decarbonizing overtake the growth in traffic, it is very misleading to label anyone in the aviation industry sustainable.” Yet Jammes says air travelers can expect to see a rapidly improving landscape around airline sustainability.
