COBALT is essential to modern technology. All sorts of electronic devices rely on it, along with other elements such as lithium. Solar panels and electric vehicles (EVs) wouldnt function without them. While the environmental degradation associated with both lithium and cobalt extraction is well established, the issues around cobalt are even more poignant because of the manner in which it is mined in the Democratic Republic of Congo. A new book, Cobalt Red: How the blood of the Congo powers our lives, published in January this year, details the human suffering, especially of children, directly involved in the mining. Written by a Nottingham University professor, Siddartha Kara, from first-hand knowledge gained by visiting the Congo, this is a book that should be required reading for every local authority that is implementing the Net Zero agenda. (You can read a review here). Professor Kara is a British Academy Global Professor and Rights Lab Associate Professor of Human Trafficking and Modern Slavery. He advises several UN agencies and numerous governments on anti-slavery policy and the law. We should take him seriously.
