Combatting Wildlife Crime in Maritime Supply Chains. Wildlife traffickers exploit weaknesses in maritime trade to smuggle illegal wildlife and timber, with up to 90% of trafficked wildlife transported by sea. Corruption, falsified documents, and hidden cargo make detection challenging. To help the shipping industry identify red flags, TRAFFIC and WWF have developed the Red Flag Compendium - a practical guide highlighting suspicious activities, at-risk routes, and key indicators of illegal trade. By strengthening safeguards, maritime companies can protect their operations, employees, and global biodiversity.
