The Action Group against Money Laundering in Central Africa organised a launch seminar for a typologies study on money laundering, terrorist financing and proliferation financing risks linked to environmental crime and the illicit trafficking of precious stones and metals in Central Africa. The seminar took place in N’Djamena, Chad from 10 to 14 November 2025. The event brought together experts and officials from forestry and water, environment, mining, customs, financial intelligence units, the Extractive Industries Transparency Initiative, the TRAFFIC network, as well as parliamentarians, civil society and academics. Discussions focused on defining relevant offences, assessing associated AML/CFT risks, profiling potential perpetrators, identifying laundering methods, and mapping limitations in the legal and institutional frameworks, alongside initial reform options. Participants also worked on establishing an initial dataset on these crime areas and on methods to research and fill information gaps to support the subsequent conduct of the typologies study.
