Transparency in international cooperation relies on easy-to-understand, timely, accessible and detailed information. GIZ contributes to providing this and has a transparency policy with clear directives, which also cover information sharing.

Transparency is one of the central issues in international discussions on improving the effectiveness of development cooperation. Germany is a member of the International Aid Transparency Initiative (IATI), and has been reporting in accordance with IATI standards since 2013.

GIZ supports the German Federal Government in meeting its international transparency obligations, for example in preparing the German IATI report, and it publishes extensive information about its work. This information includes a series of corporate reports and publications, brief reports about central and decentralised evaluations, and data and brief descriptions relating to GIZ projects. GIZ also publishes its invitations to tender and provides an overview of the contracts it has awarded.
