The Global Slavery Index is a project of the Minderoo Foundation which is based in Australia. They have a team of over 25 employees across seven locations and the Slavery Index is one of 7 major global initiatives. The Global Index is developed by the Walk Free team. They also have an investor tool kit (see link below). This tool kit is designed to help businesses and investors take action to improve human rights standards in their supply chains and combat forced labor, human trafficking, and other forms of modern slavery. In March 2020, the Minderoo Foundation conducted a study entitled “Combatting Human Trafficking since Palermo: What Do We Know about What Works?”, in which they evaluate projects and outcomes. Here is a link to the journal article: Human Trafficking “What Works” Study. This is an excellent resource.
