On 15 December 2011, the ILO launched the first guidelines on how to measure forced labor of adults and children.
A landmark law passed in 2010 is the California Transparency in Supply Chains Act (SB 657) which links business to forced labor. The law requires retail sellers and manufacturers doing business in the state with more than $100 million in annual worldwide gross receipts to disclose their efforts to eradicate slavery and human trafficking from their direct supply chains for goods offered for sale. Companies are required to make these disclosures on their websites.
