November 14, 2019 – Some scientists are serious about resurrecting zeppelins for low-carbon travel.
This August, Greta Thunberg sailed across the Atlantic in a zero-emission sailboat to protest the high carbon footprint of plane travel. But there’s good reason to think she may someday travel to climate protests via airship — the same giant aircraft, buoyed by gas-filled balloons, that were popular in the early 20th century. Faster than cargo ships and able to alight inland as well as on a beach, many airships, also known as dirigibles, have fewer emissions than boats, and all are much more carbon efficient than planes.
While interest in early dirigibles waned after they proved too slow and, occasionally, too dangerous, climate change is making plane travel increasingly contentious. Now some scientists are considering airships as a serious transportation solution.
Unlike planes, airships don’t need to burn much fuel to take off and propel themselves. Because they move more slowly than planes, they’re being eyed as a much more carbon-efficient way to move air cargo, which is set to triple in the coming decades, according to the International Air Cargo Association. “An airship produces 80% to 90% fewer emissions than conventional aircraft,” said Jean Baptiste Meusnier, spokesperson for the International Air Transport Association.
