International Responsible Business Conduct (IRBC) has completed a project examining aluminium and bauxite supply chains to improve transparency and traceability in materials supporting the renewable energy transition.
The project brought together wind energy company Siemens Gamesa, Dutch cable manufacturer TKF, Digital Product Passport (DPP) technology provider Minespider, and project partner Responsible Trade.
The initiative mapped selected upstream aluminium and bauxite supply chains and tested secure DPPs to organise and present traceability and sustainability information across multiple supplier tiers.

The work highlighted the progress possible through collaboration among industry participants, alongside the challenges of obtaining and validating information further upstream in supply chains.
Siemens Gamesa participated to explore greater visibility into the materials used in wind energy systems. TKF, which supplies cables for offshore wind farms and other energy projects, shared its views on responsible sourcing and supply-chain transparency.

The project was part of the IRBC Agreement for the Renewable Energy Sector, which aims to protect human rights and the environment across global renewable energy supply chains.
The findings can help guide future industry projects on responsible sourcing, working with suppliers and making supply chains more transparent.
