S&P Dow Jones Indices has removed electric carmaker Tesla Inc from its widely-followed S&P 500 ESG Index, citing issues including racial discrimination claims and crashes linked to its autopilot vehicles, a move that prompted critical tweets from Tesla CEO Elon Musk on Wednesday.Other contributing factors to the changes, effective May 2, included Tesla’s lack of published details related to its low carbon strategy or business conduct codes, said Margaret Dorn, the organization’s head of ESG indices for North America, in an interview.
