For now，these in­development electric planes are small，with room for up to just 30 passengers.And they can't travel far­powered by more than 5 tons of onboard lithium batteries (锂电池)，the electric plane can only fly 124 miles on one charge.But with help from a fuel­powered generator，it can expand its range to nearly 500 miles.And even this so­called “hybrid mode” would still produce 50 percent fewer emissions than standard planes.These electric planes would also be much quieter. The Swedish company says its planes could be ready as early as 2028，but the vehicles will need to pass an array of regulatory hurdles before they can take flight. Airlines—and the travel industry as a whole—have__come_under_fire for their environmental impacts.Thus，they're responding with ambitious targets and plans.United Airlines，for example，has promised to reduce emissions by 100 percent by 2050 through a combination of cleaner fuel and carbon offsets，while countries like Denmark and Sweden have set goals of stopping using fossil fuels for domestic flights by the end of this decade.Cruise lines have also vowed to take action on climate，with companies like Hurtigruten Norway planning to launch the first zero­emission passenger ship by 2030.Trains，
