In a press release distributed on October 23, 2013 BM&FBOVESPA announced that, “BM&FBOVESPA will start annual compensation of its greenhouse gas emissions that cannot be reduced, thus becoming carbon neutral. This initiative is being backdated to 2011 and 2012 and seeks among other things to encourage the adoption of best sustainability practices by listed companies and by the market as a whole. This course of action is also in line with the Exchange’s Sustainability Policy – approved by the Board of Directors in 2013 – and cements the commitment to business initiatives related to climate change.”
