She has been involved in the Kimberley Process since 2001, when she was working for the United Nations as the diamond expert on the UN Monitoring Mechanism during the Angolan Civil War.

Emma Irwin is a mining sector governance and social responsibility expert, with over 15 years experience in countries including Mali, Guinea, Sierra Leone and Liberia in West Africa. She has most recently been working with the World Bank on Extractive Industries Transparency Initiative (EITI) implementation in Myanmar (Burma) and in Guinea. Prior to that she worked as a minerals governance adviser in Afghanistan’s Ministry of Mines, providing support on various governance and policy issues including reviewing and updating the ASM formalisation strategy.
She has extensive experience working ‘on-the-ground’ with mining companies and local communities in Africa and in Asia. In Guinea and Mali she worked as a social consultant for a major gold mining operation that was experiencing significant local community unrest as well as huge numbers of orpailleurs/ASM gold miners in, on and around its concession areas. Here, she carried out numerous stakeholder interviews, including with different groups within the local ASM communities (women, youth, etc), to assess the extent to which the large scale gold mining company could reach a ‘peaceful coexistence’ with the ASM community digging in its concession area. This led to the production of a site-specific strategic sustainability management framework including a social impact and community relations scoping study, a stakeholder engagement action plan and an integrated community development action plan for the company. Irwin’s work with EITI as both a technical adviser supporting countries with EITI implementation (Myanmar, Afghanistan, Guinea and Mongolia), and as a validator of countries’ compliance to the process (Mozambique and Cameroon), has also contributed to her in-depth understanding of local and regional extractive industry related challenges and opportunities, including those related to ASM.
She has extensive experience working with a wide range of stakeholders, from senior government officials to company representatives to local community based organisations. Emma has also advised a luxury jewellery company on the responsible sourcing of metals and gemstones and developed their ethical sourcing policy.
She continues to focus on and be very interested in responsible metals and minerals value chains, from mine to market, and has just been working on a baseline assessment of the gemstone sector in Myanmar for Myanmar EITI and the World Bank.
