In 2008, states, international organizations, non-governmental organizations and private companies agreed to make their spending on development cooperation and humanitarian aid comparable. For this purpose, the International Aid Transparency Initiative (IATI) was launched at the third High Level Forum on Aid Effectiveness in Accra, Ghana.
Further information on the IATI standard and all published data on development expenditure.
All development actors can use the single IATI standard to present their development cooperation work transparently and openly. The format is machine-readable (XML) and the data is published under an "Open Data" license. To date, the data of more than 800 states, organizations and institutions are freely accessible and can be explored via various online tools.
Welthungerhilfe (WHH) also publishes its project data according to the IATI standard – transparently and openly.
