Publish What You Fund, the global campaign for aid and development transparency, has today revealed the full list of agencies that will be assessed in the 2026 Aid Transparency Index. A total of 34 organisations will be included, combining agencies that have opted into a new paid-for accreditation model with major bilateral donors assessed to preserve the Index’s role as an independent benchmark of transparency.

The Aid Transparency Index has been a cornerstone of global transparency efforts since 2012, providing rigorous, peer-reviewed analysis of how aid and development finance is disclosed. To ensure the sustainability of this valued accountability tool, Publish What You Fund has adapted the model for the 2026 Index. Sixteen agencies have chosen to participate in the paid-for accreditation and assessment process. Publish What You Fund is pleased to announce that the Green Climate Fund will participate in the Index for the first time, and the United Nations Development Programme, a leader in aid transparency, has joined the list of participating organisations. These participating agencies will benefit from training and peer networking, engagement and feedback from the highly experienced Publish What You Fund team, and will also receive accreditation for their transparency performance.

To maintain the Index’s role as an independent measure of the transparency of the world’s major aid and development organisations, Publish What You Fund has announced it will also include 18 of the major bilateral donors assessed in the 2024 Index. These agencies have chosen not to sign up for the full accreditation process, but they will be scored alongside the accredited organisations, using the same assessment method and scoring approach, and they will all appear in the Index ranking. A total of 34 agencies will now be assessed, representing two-thirds of spending published to the International Aid Transparency Initiative standard in 2025. By opting out of the accreditation process, however, the non-accredited organisations will not receive the engagement, feedback and capacity building benefits.

Gary Forster, CEO of Publish What You Fund, said:

“We are deeply grateful to the agencies that have chosen to be part of the accreditation process for the 2026 Aid Transparency Index. Their decision demonstrates a clear commitment to transparency and to sustaining a global public good that benefits the entire aid and development community. Their support allows us to continue applying independent scrutiny across the world’s leading donors and to maintain a robust, comparable global dataset.”

“With aid budgets under strain and donors under pressure, transparency is essential for coordination and learning, and for demonstrating value and impact. While our business model has evolved, our mission has not: we remain fully committed to driving transparency and accountability among the world’s leading aid donors.”

The 2026 Aid Transparency Index will be launched in November 2026.
