President, Sustainable Development Commission, World Jewellery Confederation (CIBJO)

John Mulligan is Head of Sustainability Strategy at the London-based World Gold Council (WGC), leading its climate change and nature research programmes and associated engagement with investors, policy makers and stakeholder organisations. Furthermore, he contributes to the organisation’s wider insight and communications outputs to improve understanding of the whole gold supply chain, and the integration of ESG and sustainability considerations into strategic market perspectives. Mulligan also serves as President of the Sustainable Development Commission of CIBJO (World Jewellery Confederation), chairs the climate programme of the Watch & Jewellery Initiative 2030 (WJI2030) and is the main convenor of the industry group backing the Gold Industry Declaration of Responsibility & Sustainability Principles. Additionally, he recently assumed the role of Chairperson of the ISO (International Standardization Organisation) Technical Committee on Jewellery & Precious Metals.

“I am delighted to be invited back to help judge the Sustainability Awards 2025 by JWA. In a world facing unprecedented social and environmental challenges, against a backdrop of escalating tensions and increased fragmentation, we need to find platforms to communicate and celebrate our shared sustainability goals. We also need to come together to develop a clearer vision of what success might look like if jewellery industry practitioners focus on positive actions and outcomes beyond their direct markets and products. I hope these Awards will continue to foster that common understanding and convergence, while inspiring others in the industry to commit to embedding sustainability at the heart of their businesses,” Mulligan said.
