The Asian Development Bank (ADB) has issued its Sustainability Report every 2 years since 2007. ADB’s Sustainability Reports allow our stakeholders to assess our operational and organizational sustainability performance and provide them with a single point of reference to understand our commitment to sustainable development. For 2016, this annual Sustainability Report highlights the integration of sustainability into ADB’s investments and organizational activities during 2015. A separate detailed Global Reporting Initiative (GRI) index contains the responses of ADB to standard and specific disclosures in the GRI’s G4 Sustainability Reporting Guidelines and G4 Financial Services Sector Guidelines. The Sustainability Report and detailed GRI Index are prepared in accordance with the G4 Sustainability Reporting Guidelines and are available online at www.adb.org/documents/asian-development-bank-sustainability-report-2016.
