The world’s biggest container ship. The giant vessels that carry colorful boxes of cargo around the world are becoming more energy efficient. China’s COSCO Shipping has outfitted its container ships with new propellers and a protruding “bulbous bow” to reduce wave resistance and curb fuel consumption. CMA CGM of France has equipped vessels with electronically controlled engines to optimize performance, and more of its ships can plug into shoreside electricity supplies to avoid running their massive diesel engines at berth. As a result, carbon emissions associated with moving those boxes have steadily declined in recent years. From 2009 to 2017, container ship emissions dropped roughly 37 percent on average — per container, per kilometer for global ocean transportation routes, the Clean Cargo Working Group reported earlier this month. (Per mile, that’s about a 60-percent reduction.) But that progress is starting to level off, showing the limits of the shipping industry’s existing actions to tackle climate change, according to the new study . Examining the emissions-reduction efforts of those operating container ships could help illuminate some of the challenges involved in getting oil tankers, bulk carriers, and other types of cargo vessels to curb pollution. Container ships account for only […]
