This article examines the intersection between forced labour, supply chain risks and environmental, social and governance concerns that pose a threat to the ‘Just Transition’. It addresses how states, businesses and other stakeholders drive or fail Just Transitions and why. Through an application of a ‘policy currents framework’ to the case study of solar panel supply chains originating in China, we analyse states, international organisations and civil society organisations’ framing of modern slavery issues in the context of the ‘Just Transition’. We focus on the framing of challenges and solutions to the nexus of forced labour and climate change. We draw attention to the fact decarbonisation risks are being achieved at the cost of labour rights abuses within supply chains, question whether the concept of renewable sources is ‘Just’ and provide a series of recommendations for stakeholders.
