The Action Group against Money Laundering in Central Africa (GABAC) held a launch seminar in N’Djamena, Chad from 10 to 14 November 2025 to kick off a typologies study on money laundering, terrorist financing and proliferation financing (ML/TF/PF) risks linked to environmental crime and the illicit trafficking of precious stones and metals in Central Africa. Held under the patronage of Chad’s Minister of State for Finance, Budget, Economy and Planning, the seminar convened experts and officials from water and forestry, environment, mines, customs, financial intelligence units, the Extractive Industries Transparency Initiative (EITI), the TRAFFIC network, as well as parliamentarians, civil society and academics. Over four days, participants exchanged presentations and debates to clarify the underlying offences, identify ML/TF-related risks and laundering methods, develop perpetrator profiles, assess legal and institutional gaps, outline reform options, and assemble a data set and research approach to support completion of the typologies study.
