Currently, about how much world’s goods trade (by volume) is carried on ships?

Approximately 80% of global goods trade by volume is transported via ships, as maritime transport is the backbone of international commerce, carrying bulk goods like oil, grains, and containers. This cost-effective method dominates due to the global economy’s reliance on sea routes. Studying maritime trade highlights its role in globalization, the challenges of logistics and environmental impact, and its economic significance. It also offers insights into how shipping shapes supply chains, providing lessons on the need for sustainable practices and infrastructure to support global trade efficiently.
