90 Percent of the world’s cargo is transported by shipping container. The number of containers keeps increasing. In 2019 the total throughput was 800 million TEU. TEU stands for Twenty-foot Equivalent Unit, the length of a standard shipping container. COVID caused a small dip in the increase for 2020, but the forecast for 2021 is 827 million and the total throughput is forecasted to rise to 924 million in 2024.
