We started our campaign for aid transparency in 2008. Since then, most major international donors have published open aid data that is unprecedented in its detail and scope. Our flagship Aid Transparency Index shows how different donors compare in terms of transparency.

Beyond the Index, our work is about understanding and using open aid data. We partner with people in government, civil society and the media to access and use open aid data in specific sectors and countries. We believe that this is essential to making aid and development finance more effective and more accountable. Donors have a responsibility to publish information that is timely, comprehensive and forward-looking, but they also have a responsibility to make sure the information is useful and used.
