On Business Weekly this week, we look at the efforts being made to reduce the carbon footprints of mining companies. One of the largest iron ore producers, Fortescue Metals, is looking to reduce its carbon emissions and has snapped up the technology research arm of the Williams Formula One team to help them do it. Plus, we examine the continuing war on drugs and how the Mexican cartels have been taking advantage of the pandemic restrictions in the United States. Also, we ask if having one or two wealthy owners is the best route to a winning strategy for football clubs. We review the deal that the Australian government struck to buy the licence for the Aboriginal flag – now that the image is free to use, is that the end of the matter? And Bob Dylan is, once again, selling off his assets – this time, his back catalogue is going to Sony Music for an estimated $200m. Business Weekly is presented by Matthew Davies and produced by Philippa Goodrich.
