The Asian Development Bank (ADB) has been issuing its Sustainability Report since 2007. The Sustainability Report allows stakeholders to assess ADB's operational and organizational sustainability performance, providing them with a single point of reference to understand ADB's commitment to sustainable development. For 2018, this biennial Sustainability Report highlights the integration of sustainability into ADB's operations and organizational activities during 2016–2017. A separate detailed Global Reporting Initiative (GRI) Content Index sets out ADB's management approaches to material topics and responses to general and specific disclosures in the GRI Sustainability Reporting Standards. The Sustainability Report and detailed GRI Content Index are prepared in accordance with the core option of the GRI Sustainability Reporting Standards and are available online at www.adb.org/documents/asian-development-bank-sustainability-report-2018.
