A/HRC/31/58 (iii) Promoting active membership of INTERPOL and partaking in and utilizing effectively the Green Notice system, particularly for the identification of travelling sex offenders; (c) Holding military and peacekeeping troops and personnel accountable in cases of child sexual exploitation by having zero tolerance for such crimes, setting up prompt and thorough investigations, implementing strong penalties for those guilty of such crimes, taking measures such as suspension, repatriation and termination of the deployment and ensuring the follow-up to those procedures. Care, recovery and reintegration measures should also be provided to child victims as part of their right to a remedy. 3. Corporate social responsibility 84. The Special Rapporteur highlights the importance of enhancing corporate social responsibility, particularly with regard to the servicing of demand. Existing guidelines, such as the Guiding Principles on Business and Human Rights, the Global Code of Ethics for Tourism and the Code of Conduct for the Protection of Children from Sexual Exploitation in Travel and Tourism, should be universally followed by members of the private sector and mainstreamed in all their activities and across the supply chain. Compliance with those guidelines should be enforced and monitored. 85. There is a need for State intervention when the private sector does not take sufficient measures to ensure that it does not become or remain a facilitator in the demand for the sexual exploitation of children. Measures such as conducting background checks, particularly for employment that involves coming into contact with children, such as childcare workers, should become a mandatory practice. 22
