Nearly everything we consume is transported by ship. The biggest container ships in the world are among the largest moving structures made by man and can carry over 24,000 20-foot container units. The standardisation of these simple metal containers in the 1950s and 60s marked a turning point in world trade, driving down costs and ultimately fuelling globalisation. Now that supply chains have become ever more complex and been put under increasing strain, we take a look at the history of the shipping container. Joining Rajan Datar are Marc Levinson, American historian and economist and author of The Box: How the Shipping Container Made the World Smaller and the World Economy Bigger; Alan McKinnon, professor of Logistics at Kühne Logistics University in Hamburg and author of Decarbonising Logistics: Distributing Goods in a Low Carbon World; Yash Gupta, shipping industry expert with over 20 years’ experience in vessel management and logistics.
