Sustainability Report 2021

While this transition has been transformational for our business, we remain highly cognisant that reducing the emissions from our operations is equally important. We will not simply rely on the production of clean energy products, but focus on how we supply these products in the most carbon efficient and sustainable manner. In FY21, our solar farm at Nova continued to significantly reduce our diesel usage and consequently, carbon emissions. In addition, we have made substantial progress in reducing non-recyclable waste streams from both operations and our remote exploration activities – yet another way we are ensuring we minimise our impact on the planet. Looking ahead, our commitment to decarbonising our operations goes a step further. In line with our aspiration to be carbon neutral by 2035, we have completed a number of work programs in FY21 to strengthen our climate change roadmap and strategy. These include: • implementing an internal carbon price and decarbonisation fund • developing a pipeline of emission reduction projects at our Nova Operation, as we strive to decarbonise the Operation • developing a strategy for understanding, reporting and influencing the emissions of our value chain; and • developing a carbon removal and offset strategy. In addition, as we commence our joint venture business with Tianqi, we will work collaboratively on programs of work which can be undertaken to reduce emissions from both Greenbushes and Kwinana operations. PRIORITISING OUR PEOPLE At the heart of our sustainability strategy – and our business – are our people. As our greatest asset, our first responsibility is to keep our people safe, and we have continued to work on improving our safety performance throughout FY21. There is always more to do, but key lead and lag indicators have demonstrated an improvement relative to the prior financial year. In addition, it is also important that we recognise that caring for our people goes beyond physical safety. IGO takes a holistic view and we include programs that support our team’s physical, mental and financial wellbeing. The support we provide in this area has been particularly important during FY21 as the COVID-19 pandemic continues to impact the way in which we all live and work. Thankfully, Western Australia, where most of our operations are located, has been relatively unaffected by the pandemic, however, we acknowledge the additional pressure these unprecedented times have placed on our people and their families over the last 18 months. Our resilience as an organisation is a direct reflection of our strong culture and we are proud of the ongoing progress that has been made in FY21. Our 2021 Engagement Survey demonstrated the continued pride our people have for working at IGO and highlighted that our culture continues to be defined by our people as friendly, flexible, happy and ambitious. The culture we have built is one of our competitive advantages, our people want to be part of our future and we receive consistent feedback from our people that they are excited about our purpose and strategy and enjoy being part of the IGO community. CREATING SHARED VALUE Our purpose, Making a Difference, is a philosophy that extends to our interaction with our host and local communities. Our approach to Traditional Owner engagement is focused on the notion of partnership aimed at achieving positive long-term social, environmental, and economic outcomes. As a key workstream in FY21, we undertook an independent third-party review of our cultural heritage management practices, which identified several areas where we could improve. These have already been prioritised or changes have been implemented. IGO continued to support the local communities in which we operate through both financial and non-financial support for organisations focused on child health and education. As well as providing over A$900,000 of funding through our Corporate Giving program in FY21, IGO supports a range of organisations through employee volunteering programs and in-kind contributions that deliver positive outcomes and create shared value for our communities. THANK YOU Our reason for being is focused on creating a better planet for future generations by delivering products critical to clean energy. Despite the ongoing global challenges, IGO is in an outstanding position. This is thanks to our dedicated, innovative, and hardworking people, their families, our host communities, suppliers, contractors, industry associations and regulators. Thank you for all that you do to support our purpose of Making a Difference. We will continue to work to meet our stakeholders’ and society’s expectations and will do so with sustainability at our front of mind. We would also like to thank our shareholders for supporting our sustainability practices and reporting, and for your faith in the IGO Board and Executive Leadership Team (ELT) throughout the year. We are proud of what we are achieving in the Environment, Social and Governance (ESG) space and look forward to building on this performance in years to come. In this, our seventh Sustainability Report, we have further aligned with the GRI standards and Taskforce on Climate- related Financial Disclosures (TCFD) recommendations. As always, we encourage your feedback. Thank you for your ongoing support.
