Diversified mining and marketing company Glencore enters 2017 with a fully restored balance sheet. The London-, Hong Kong- and Johannesburg-listed company’s 207% year-to-date share price rise is showing up yesteryear’s BHP Billiton and Rio Tinto. The tragic Samarco slimes dam deaths in Brazil continue to haunt BHP and the disgraceful bribery scandal at Simandou is continuing to shame Rio. Glencore, on the other hand, is aspiring to keep itself squeaky clean, helped by its firm commitment to Voluntary Principles on Security and Human Rights and its reaffirmation of the United Nations Universal Declaration of Human Rights and the world body’s Guiding Principles on Business.
