17. Sea of trouble: Turning our ships green

In the run-up to the COP 27 global climate summit, The Weekly Tradecast looks at why ships and ports must drastically cut greenhouse gas emissions with Jan Hoffmann, head of trade logistics at UNCTAD.

Tune in to find out how the shipping sector can transform to reduce emissions and help protect the planet.
