Cargill Inc., the world’s biggest agricultural commodities trader, plans to harness wind power by fixing massive wing sails to some of its cargo fleet to reduce fuel use and greenhouse gas emissions.
Shipping is responsible for about 90% of world trade, and it also accounts for almost 3% of man-made carbon-dioxide emissions. The industry has vowed to cut greenhouse gas emissions by 50% by 2050, from 2008 levels. How it gets there and what new fuel technologies it uses to replace traditional petroleum-based ones is still up for grabs.
