Norges Bank, the Norwegian central bank which manages the NOK2.7trn (€354bn) assets of the Global Pension Fund, has issued a warning that it is expanding its expertise in child labour issues and that it will track companies for up to 20 years. Child labour is one of six focus areas for the fund, the others being water management, climate change, equal treatment of shareholders, board accountability and efficient markets.
