"Quants have found that raters’ different ways of refining the raw data they gather adds further to the confusion. Leading providers concur on only about half the companies they rate according to data from State Street Global Advisors. Some score companies by picking out the best and worst performers overall. Others pick out the best and worst by industry. “You can come up with an oil “ company that has a huge carbon footprint but good sustainability ratings,” says Gianfrate. Some raters score missed reporting ” fields as neutral, others penalise them.“No serious scholar at this point in time will say we have enough “ consistent evidence on whether ESG investing can relate to superior performance,” says Gianfranco Gianfrate, a professor of ” finance at Edhec Business School."
