Set up ten years ago, the Joint Audit Cooperation (JAC) initiative brings together 16 members, who account for 2.7 billion connections worldwide, and seek to address these challenges. Given that most telcos are in business with the same major hardware suppliers, JAC also helps strengthen their bargaining position to make CSR commitments stick. These efficiency gains also apply to suppliers: They now need only answer one assessment and on-site audit request – as well as work on corrective actions – with all their customers.
