With an estimated 50 million people living in modern slavery worldwide and an estimated 130,000 victims in the UK, countries are moving to make businesses more accountable for abuses in their supply chains. Governments around the world are insisting on antis-slavery disclosure transparency with a steady increase in criminal and civil enforcement actions being taken. No longer can businesses relinquish their responsibilities and turn a blind eye to what’s happening in their supply chains.
The built environment is high-risk for modern slavery and labour exploitation because of significant labour demand, a severe skills shortage, complex supply chains and the prevalence of indirect and self-employment.
Operation Cardinas unravelled how an organised crime group placed more than 500 victims of modern slavery onto major construction sites in the South East between 2008 – 2019.
Consider your global supply chains – according to the Global Slavery Index 2023, at risks goods imported by the G20 are worth US$468 billion. Some of the big high-risk categories include electronics (US$243.6 billion), garments (US$147.9 billion) and solar panels (US$14.8 billion).

Procurement Guidance: Addressing Modern Slavery in Solar PV Supply Chains

Download this free procurement guide written by Action Sustainability. The guide looks at the modern slavery risks and impacts in the PV supply chain, then outlines critical steps to address these issues throughout the commercial lifecycle (taking into account leverage). It offers insights into effective solar PV procurement due diligence, with practical tips and guidance for implementation.
With an estimated $14.8 billion of solar panels imported by G20 countries at risk of containing modern slavery, everyone who influences the procurement of solar PV has a role to play.
If you use the guide, you can’t claim assurance of zero forced labour in your supply chain, but you can say you’re aligned with procurement best practice for solar PV.
NOTE: This guide focuses on solar PV; however, the content is transferable and could be used to support responsible sourcing strategies for other renewable energy technology.
