We’re going back to wood ships with sails for international trade. It’s “progress.”
To get on track to reach net zero emissions by 2050, international shipping will have to reduce its emissions by 15% by 2030. So far, emissions from the industry have been going more or less consistently in the other direction.
One way to reduce emissions from shipping is to introduce a very old technology: sails. Wind is a clean source of propulsion that is often in abundance at sea. Some shipbuilders are taking this inspiration from the past extremely seriously, and even making the structure of the ship out of wood.
