In Iran's legal markets, the price of a kidney ranges from $2,000 to $4,000. On the black market, the same kidney can be worth over $160,000, with most of proceeds taken up by middlemen. In addition, these black market transplants are often dangerous to both the donor and recipient, with some contracting hepatitis or HIV. 

The primary strategy is to increase the supply of legally donated organs, thereby decreasing the demand. 

This includes 17.3 million people who are exploited in forced labour exploitation in the private economy and 3.9 million who are subjected to state-imposed forced labour. 

Slavery can exist in every stage of the supply chain, from harvesting or extracting raw materials – such as cocoa or cotton – to manufacturing and shipping. The reality of this is children forced to mine cobalt for use in the latest mobile phones, or women forced to produce coffee for one of our best-known brands. 

Companies have a responsibility to make sure their goods and services are never produced with slavery. This isn’t just about the goods they make in their own factories: they must also make sure slavery is not used by their suppliers, their suppliers’ suppliers, and so on all the way down the supply chain.
