VOLUNTARY BENCHMARKING & EXTERNAL ASSESSMENT IGO participates in external benchmarking initiatives and sustainability-related assessments. We are deliberate in our participation, choosing those that add the greatest value to IGO or those more broadly recognised by external parties and investors. A range of organisations offer third- party assessments of sustainability performance and act as de facto sustainability ratings agencies. Few provide their results freely. Rather, participation in many assessments and access to the resultant comparative data is provided on a fee-for-service basis. Furthermore, we are subject to the opinions of third-party organisations and initiatives, which assess and recognise our performance, based on publicly available information only. The outcome of these external benchmarking assessments informs the continual improvement in our management approaches, sustainability performance and external disclosure. In FY20, IGO actively participated in the following: • Dow Jones Sustainability Index (DJSI) The DJSI World is a respected global sustainability benchmark for investors to track the stock performance of the world’s leading publicly listed companies in terms of economic, environmental and social criteria. IGO was included as an index component of DJSI Australia in FY20, which includes those companies assessed as being among the top 30% of sustainable businesses within the ASX 200 listed companies. We are proud of this result. • CDP is an independent, non-profit organisation that runs a global disclosure system to encourage companies worldwide to measure and manage their ESG impacts. IGO participated in all three assessments in 2019 — climate change, water and forests. Our climate change score improved from D to C and our water disclosure was scored as B-. IGO’s response to the 2019 forest questionnaire was not scored because CDP have yet to develop its scoring methodology for mining companies. CDP have informed IGO that 2020 responses will also not be scored. As such, IGO made the decision not to respond to the 2020 forest questionnaire and understand that IGO will be given an F or ‘Failure to disclose’. • ISS Environmental and Social Disclosure Quality Score ISS uses a scoring and screening process to measure and identify areas of ESG risk through company disclosure. This assists investors in their assessment of a portfolio’s exposure to risk. They assess the quality of ESG practice across industry groups, such as metals and mining, with a score of 1 to 10, with 1 indicating ‘better disclosure and lower risk’. In FY20, IGO scored 2 for ‘governance risk and disclosure’ (improving from a 3 in FY19), 3 for ‘environmental risk’ (improving from a 6 in FY19) and 2 for ‘social risk’ (improving from a 4 in FY19). In FY20, our overall sustainability performance improved considerably in all three benchmarking assessments. The quality of corporate sustainability reporting is also completed by various non-government organisations and investment bodies such as the Australian Council of Superannuation Investors (ACSI) which conducts an annual review of the quality of ESG reporting by each ASX 200 company. ACSI has rated IGO's sustainability reporting as 'Leading' for the last five consecutive years. We will continue to pursue a leading position in sustainability and ESG reporting. MEASURING OUR SUSTAINABILITY PERFORMANCE Internal assessment We assess our sustainability performance across a range of indicators that are important to both IGO and our stakeholders. We monitor the success of incremental and continuous work improvements against a range of quantitative and qualitative performance metrics. These indicators and their FY20 outcomes are summarised below. Our actions to maintain or improve performance in these areas are described throughout this report. IGO SUSTAINABILITY INDICATOR FY20 FY19 OUTCOMES IN FY20 ADDITIONAL INFORMATION SAFETY Safety of our workforce FY20 was a poor year for IGO in respect of safety outcomes. It is with sadness we note the death of one of our contractors’ employees at our Nova Operation. Page 48 Safety of our host communities During FY20 our activities resulted in no significant safety issues in the communities in which we operate. We have focused on minimising the risk to the health and safety of our broader community during the COVID-19 pandemic. Page 76 COMMUNITY Diversity of our workforce We maintained our workforce diversity and female representation numbers during FY20, currently above the industry average. Page 43 Local and Aboriginal employment We continued to apply ourselves to increase the number of people employed in our business from our host communities. However, we have limited success to date (in part because this is a complex challenge). We expect an improved result in FY21. Page 44 Community engagement We made significant improvements in our engagement activities during FY20. Page 76 Land access We experienced no issue accessing the land we sought for exploration purposes. Page 28 Local sourcing of goods and services While IGO sources some goods and services locally, we still have room for improvement. Page 89 Corporate Giving contributions Proudly, we continued to support our Corporate Giving priorities in local health, education and environmental management. In FY20 we again increased the budget allocated to these activities and made additional contributions to support COVID-19 and bushfire recovery. Page 80 Education and training IGO continues to engage in a range of initiatives to support education and training of our people, our host communities and support of the industry generally. Page 42 ETHICS AND INTEGRITY Compliance In FY20, IGO was not subject to legal action or prosecution. There was one non-compliance of note, disclosed on page 36. Page 36 Tax IGO continues to make significant tax contributions. Page 38 Transparency IGO is open and transparent, and where we are unable to make disclosures for commercial reasons, we are forthright in stating our position. Page 38 LAND MANAGEMENT Reducing our exploration impacts Given current technologies and the locations of exploration interests to IGO, land clearing remains an unavoidable component of our activities. Page 53 Reducing our operational impacts The impacts associated with the Nova Operation are minimal. Page 53 RESOURCE MANAGEMENT Water use The impacts associated with IGO’s water consumption are negligible. We undertook a significant program of work in FY20 to improve the accuracy of our Nova Operation’s water balance. Page 60 Resource recovery IGO continues to achieve strong resource recovery. Page 30 EMISSIONS AND WASTE Energy consumption and renewables Energy consumption during FY20 remained proportionate to our activities. We successfully commissioned the solar power farm at our Nova Operation, which is expected to reduce our emissions by approximately 6,500 tonnes of CO 2 per year. Page 72 Contained waste IGO’s key waste streams were contained to design during FY20. Page 56 Discharges to land and water In FY20, IGO had no material discharges to land, water bodies, water courses or groundwater. Discharges to the atmosphere reflect a change in the scale of our operating activities.
