In general, initiatives to combat child sex tourism (CST) and child trafficking for sexual exploitation in the past rarely included the active engagement of the private sector in the process of planning and implementation…Yet, there is much more that the private sector can and is willing to do…ECPAT International has noted a number of good practices and lessons learned over the years in its work with the tourism industry…Many of these good practices have been the result of the Code of Conduct for the Protection of Children from Sexual Exploitation in Travel and Tourism…a corporate responsibility tool supported by ECPAT and implemented by signatory companies from the tourism industry…This paper will provide a brief background on the Code of Conduct as well as present four key lessons learned from good practices of the ECPAT network, working in collaboration with various private sector partners [refers to Hotelplan, Kuoni Scandinavia, Six Senses, Accor Hotels (part of Accor)]
