A coalition of Mozambican non-governmental organisations has reported mining giant BHP Billiton to the Johannesburg Stock Exchange's Socially Responsible Investment Index (SRI) for 'intolerable conduct' in planned pollution at its aluminium smelter in Mozambique, a spokesperson said on Tuesday. The coalition of environmental and human rights NGOs sent a formal complaint to the JSE at the end of October, Vanessa Cabanelas, spokesperson for the environmental organisation Justica Ambiental, told the South African Press Association (Sapa).
