A dramatic change in the ethical investment profile of the tech sector gets underway today with Dow Jones Sustainability Index (DJSI) dumping HP and Microsoft from its listing...Earlier this year HP’s sustainability report recorded a ratcheting down of social investment & supply chain due diligence and a less than muscular approach to conflict minerals...Microsoft...has developed an inconsistent record on sustainability reporting...It's a big turn around in just a few short years from when these two titans set the standard on sustainability for the tech sector...On a brighter note - Alcatel Lucent, NTT DoCoMo, EMC, Sprint Nextel & Xerox are added to the index while Samsung takes tech sector leadership overall.
