NYSE Euronext joined a United Nations initiative to promote corporate sustainability reporting and responsible investment. This makes NYSE Euronext the eighth stock exchange to join the initiative, which encourages exchanges to work with investors, regulators and companies to enhance transparency around environmental, social and governance issues. United Nations Secretary-General Ban Ki-moon urged other exchanges to follow NYSE Euronext's lead in committing to sustainability. The announcement sets the stage for a discussion of sustainability-oriented listing guidelines at an upcoming meeting of the World Federation of Exchanges.
