Containerization has been one of the key drivers of globalization, making shipping of even low value items cost effective from all corners of the globe but especially from Asia. Speed used to be important in shipping containers, but Maersk, a major operator, has started to halve the top speed of some of its container ships. The result has been a 30% reduction in energy consumption, and a 30% reduction in carbon emissions as well. Expect to see more companies slow down their ships -- after all, Wal-Mart and Best Buy can always wait an extra week to receive their cheap Asian imported goods.
