From 2 to 4 December 2025, the United Nations Development Programme (UNDP), the United Nations Office on Drugs and Crime (UNODC), the International Anti-Corruption Academy (IACA), the World Bank, and the Organisation for Economic Co-operation and Development (OECD) hosted the Second Global Conference on Harnessing Data to Improve Corruption Measurement at the United Nations Headquarters in New York. The Conference brought together policymakers, practitioners, and experts from governments, civil society, international organizations, and academia to exchange experiences, good practices, and innovations in measuring corruption and the effectiveness of anti-corruption policies.

Through interactive plenaries, technical panels, and expert roundtables, the Conference explored topics such as the operationalization of the Vienna Principles, the launch of the Global Anti-Corruption Digital Dashboard, and the metadata of the Statistical Framework to measure corruption. Sessions also covered user-centred approaches, digital innovations, and emerging methods for collecting, analyzing, and using data to prevent and combat corruption.
