Un nuovo episodio del podcast Planet Money, di NPR.

Bjarne Caesar Skinnerup works as a maritime pilot in the straits of Denmark. That means he’s used to seeing oil tankers. But after the start of the war in Ukraine, the tankers started getting weird. They were flying flags he’d never seen before. They were old, very old, though many had taken on new names. Something was off.

He’d stumbled on a shadow fleet of hundreds of tankers ferrying sanctioned oil out of Russia … with near impunity.
