The Council of Europe Convention on Action against Trafficking in Human Beings,in force since 2008, provides a comprehensive framework for combating trafficking in human beings from a human-rights based and victim-centred perspective. To date, the Convention has been ratified by all 46 member states of the Council of Europe, as well as by the non-member states Belarus and Israel.The Group of Experts on Action against Trafficking in Human Beings (GRETA) is responsible for evaluating the implementation of the Convention by the States Parties. Its recommendations help to trigger legislative changes, raise awareness of the various forms of human trafficking and better protect the rights of trafficked persons.GRETA’s 13th General Report presents an overview of its activities from 1 January to 31 December 2023, including meetings, evaluation visits, country reports, round tables, and relations with other Council of Europe bodies, international organisations and non-governmental organisations. The report also includes a thematic chapter devoted to the stocktaking of the third evaluation round on the Anti-Trafficking Convention, which focused on trafficking victims’ access to justice and effective remedies.
