Abstract
This article gives an overview of current legal initiatives for enhanced transparency regulations for corporations and the actions they take against trafficking in human beings (THB). The California Transparency in Supply Chains Act (CTSCA) has an influence on legal initiatives in Europe, in particular in the United Kingdom. The UK's Modern Slavery Act includes the obligation for corporations to report on actions taken against THB and slavery. In addition, at the European Union level, measures to enhance obligatory reporting on non-fnancial matters, such as human rights matters, are to be implemented in national legislation in the next years. This article compares the California Transparency in Supply Chains Act with the UK's Modern Slavery Act. In order to decrease exploitation along the supply chain, the article concludes that legislation should not only require obligatory reporting but also oblige corporations to implement measures to prevent THB related to their activities.
