This volume presents the proceedings of the international conference Preventing Art Crimes Through Regulation and Self-Regulation, held in Milan on 30 September 2024 and organised by the UNESCO Chair on “Business Integrity and Crime Prevention in Art and Antiquities Market” in collaboration with Fondazione CNPDS. Bringing together UNESCO representatives, leading academics, and key art-market professionals from across the world, the conference offered a rare platform for dialogue between institutions and practitioners. The contributions highlight the need to strengthen public-private cooperation to prevent crimes affecting cultural property, emphasizing the importance of codes of conduct, due diligence, provenance research, and anti-money-laundering tools such as KYC practices. Combining legal, ethical, and practical perspectives, the volume provides an essential overview of current strategies to enhance integrity and transparency in the art and antiquities market.
