The document is a benchmark analysis exploring GRI environmental indicators in the banks' reports for 2013. The analysis was coordinated by ABI Lab and involved eight banks, aiming to assess the comparability of environmental data. Information was collected through a questionnaire, including energy consumption, greenhouse gas emissions, and other sustainability indicators. The analysis aims to establish reference standards for banks in preparing sustainability reports and will identify areas for improvement for the future. Challenges in obtaining accurate data for calculating indicators and the importance of greater consistency in reporting are highlighted.
