Covering the period from 1 January to 31 December 2016, the report looks back on the activities carried out by the panel of experts under the mandate provided by the Council of Europe Convention of Action against Tra cking in Human Beings (“the Convention”). GRETA’s intensive work-rate during the past year is partly due to the fact that, since the refugee protection crisis on the European continent, acts of trafficking in human beings have been an ever-present if not resurgent phenomenon, but it is also explained by the growing number of States that have signed up to the Convention. Their number reached 46 in 2016, following ratifications by Liechtenstein and Turkey, and there are more ratifications to come in the future.
