Inventories of organizations’ direct and indirect greenhouse gas emissions are instruments that permit self-assessment. They also demonstrate corporate concern, the shouldering of responsibility and engagement with climate change questions, transforming discourse into responsible attitude. B3 has made an inventory of its greenhouse gas emissions since 2009. Since 2010 it has been audited externally and the document has been included in the Public Registry of the Brazil GHG Protocol Program, where it can be seen and downloaded.
Since 2013, B3 has annually compensated its greenhouse gas (GHG) emissions that it has been unable to reduce, thus becoming carbon neutral. This process has been backdated to 2011 and 2012 and seeks among other things to encourage the adoption of best practices in sustainability by listed companies and by the market in general.
