Based on public statements and advice from IGO’s key nickel customers, we understand approximately 75% of IGO supplied nickel is processed for use in downstream battery products. In FY20, we also engaged with our suppliers and customers to gain a better understanding of our climate change risk and the indirect (Scope 3) emissions associated with our supply chain. Our Scope 3 emissions are disclosed on page 73 of this report. Finally, we completed a preliminary risk assessment of our human rights and modern slavery risk within the IGO supply chain, helping to inform our understanding of our responsible sourcing impact. The shifting global perspective on the responsibilities of the mining sector to respect and promote human rights means businesses are now required to assess and, if needed, realign their current approaches to recognising their impacts on human rights. We will provide more information on the outcomes of this assessment in the FY21 Sustainability Report and in our first Modern Slavery Statement, to be released on our website in early 2021. Read more about our Human Rights policy on page 38 of this report. Contractor management IGO engages contractors and industry experts to provide best-practice services and deliver outcomes outside our knowledge base. At IGO we treat our contractors as part of our team. We refer to them as being ‘our people’. When contractors are at an IGO site, their safety and welfare is IGO’s responsibility. IGO expects that its contractors work in accordance with our values, and that they provide their workforce with a safe system of work and a safe place of work. We expect our contractors to monitor and report on their performance, and we expect to see improved trends in measured outcomes. Put simply, we expect to see the same high standards we require of our direct employees. All contractors working at IGO-managed sites are provided with an IGO representative to manage their contract. This provides IGO with a direct opportunity to maintain ongoing management. Supporting local and Aboriginal businesses IGO applies a preferential selection process when sourcing goods and services local to our operations. We support and favour businesses in close proximity to the areas in which we operate and actively seek to engage and build capacity where suitable works are available. Providing opportunities for Aboriginal businesses is important to IGO. Our approach is guided by our Community Policy and Group Community Standard 2 – Aboriginal Employment and Business Development to drive the creation of Aboriginal employment opportunities across our business. In FY20, our total spend on Aboriginal owned or managed businesses was $4.81M.
