>Slower speeds also reduce the amount of fuel needed — making a voyage cheaper — and reduce the amount of carbon dioxide emitted into the atmosphere. “Slow speeds are a win for all,” said Leaper. The article is incorrect. Ships travel at an economical speed based both on fuel consumption, delivery timing, and trying to maximize the utility to the shipper from the cargo vessel. Slowing down means fewer voyages for each ship, and would ultimately mean either fewer voyages total (less commerce) or more ships.
