This article discusses the impact that an old technology, sails, can have on GHG emissions from cargo ships.
On May 10, the 43.5-metre schooner Avontuur arrived in the port of Hamburg. This traditional sailing vessel, built in 1920, transported some 70 tonnes of coffee, cacao and rum across the Atlantic. The shipping company Timbercoast, which owns and operates Avontuur, says it aims to prove that sailing ships can offer an environmentally sustainable alternative to the heavily polluting shipping industry, despite being widely seen as a technology of yesteryear.
Similar initiatives exist across the world. In the Netherlands, Fairtransport operates two vessels on European and transatlantic routes. In France, Transoceanic Wind Transport sails multiple vessels across the English Channel and Atlantic Ocean, and along European coasts. The US-based vessel Kwai serves islands in the Pacific. And Sail Cargo, based in Costa Rica, is building Ceiba, a zero-emission cargo sailing ship.
