Hawaiian Airlines could add electric-powered seagliders to its inter-island fleet as early as 2028. The planes, which can travel at 180 mph, wouldn’t replace the current fleet but rather work alongside it. Inter-island travel is a relatively small part of the company's overall carbon footprint. “Nevertheless, it’s still a notable development for Hawaiian, as it will help the airline get to its goal of being carbon neutral,” per Afar. “The airlines industry produces 3 percent of global carbon emissions, and airlines across the board have been investing in a wide variety of measures to reduce their emissions in recent years.”
