Santander Corporate & Investment | The launch of the MSCI ESG Screened Europe iTraxx Index, based on the MSCI iTraxx Europe Series 33 Index and the application of three MSCI filters, took place with great fanfare on June 21. Enel and Iberdrola have AAA ratings from MSCI for their ESG (environmental, social and governance) characteristics, but they have presumably been excluded from the index because of their involvement in nuclear and coal-fired energy production.
