Alternative equity market operator NSX is poised to open a new board in September devoted exclusively to clean technology stocks in an initiative that will attract former United States vice-president and environmental campaigner Al Gore to its opening in Sydney.

The Financial & Energy Exchange (FEX), which is also in the process of developing its own Australian-based energy trading platform, is to open a new equities board on the NSX devoted to the sustainability and clean technology sectors. This new sustainability investment market will go by the acronym "SIM".
