As the world transitions towards a cleaner energy future, the demand for critical minerals and strategic materials has surged. These minerals, including lithium, cobalt, nickel, copper, and rare earth elements, play a vital role in technologies like electric vehicle batteries, wind turbines, hydrogen electrolysers, and solar panels. However, the extraction and processing of these minerals often come with environmental and social challenges such as carbon emissions, land degradation, and intensive water usage. As a response to these challenges, there is a growing focus on green minerals, which are extracted and processed using sustainable, low-carbon methods. Dr. Rahman Daiyan from UNSW leads the development of tools to assess the value chain of green minerals, emphasizing their importance in clean energy technologies. Australia is positioned to be a significant source of critical minerals, but transitioning to green critical minerals requires government support and an enabling regulatory environment. The private sector is also crucial in advancing sustainable mineral production through funding and technological innovation. Green minerals are extracted and processed using environmentally responsible and low-carbon methods, involving renewable energy sources and emission reduction technologies. They are crucial for global decarbonisation efforts, providing materials for clean energy technologies like batteries and enabling supply chain sustainability. Despite the benefits of green minerals, challenges in scaling up production exist, including high costs, climate risks, and the necessity for innovative solutions. Sustainable mining practices are essential to balance the demand for critical minerals with minimal environmental impact, ensuring a sustainable transition to clean energy technologies and supporting global decarbonisation.
