South32 Ltd is a diversified mining company headquartered in Perth, Western Australia. The company operates in the base metals sector, producing aluminium, manganese, nickel, and zinc. South32 is committed to sustainability and environmental responsibility, and has set ambitious targets for decarbonisation and renewable energy.

Decarbonisation is a key focus for South32, as the company recognizes the urgent need to address climate change and reduce greenhouse gas emissions. In 2020, South32 announced a target to achieve net-zero emissions by 2050, in line with the Paris Agreement. To achieve this goal, the company is investing in renewable energy, energy efficiency, and other decarbonisation measures.

One of the ways South32 is reducing its carbon footprint is through corporate energy initiatives. The company is working to improve the energy efficiency of its operations, reduce energy consumption, and transition to renewable energy sources. South32 has implemented a range of energy-saving measures, such as LED lighting, energy-efficient motors, and improved insulation. The company has also invested in renewable energy projects, such as solar and wind power, to reduce its reliance on fossil fuels.

Corporate power purchase agreements (PPAs) are another important tool in South32's decarbonisation strategy. A corporate PPA is a long-term contract between a company and a renewable energy provider, which guarantees a fixed price for electricity over a specified period. By entering into a PPA, South32 can secure a reliable and cost-effective source of renewable energy, while reducing its carbon footprint. In 2020, South32 signed a 10-year PPA with a wind farm in Western Australia, which will provide around 50% of the electricity needs for the company's Worsley Alumina refinery.

Renewable energy is a key part of South32's sustainability strategy, as the company recognizes the importance of reducing its reliance on fossil fuels and transitioning to a low-carbon economy. South32 has set a target to source 50% of its electricity from renewable sources by 2025, and is investing in a range of renewable energy projects to achieve this goal. The company has already installed solar panels at several of its operations, and is exploring opportunities for wind, hydro, and other renewable energy sources.

In addition to its decarbonisation and renewable energy initiatives, South32 is committed to responsible mining practices and environmental stewardship. The company has a comprehensive sustainability strategy, which includes targets for water conservation, waste reduction, and biodiversity protection. South32 is also committed to engaging with local communities and stakeholders, and has established a range of programs to support education, health, and economic development in the regions where it operates.

Overall, South32 is a leading mining company that is committed to sustainability, decarbonisation, and renewable energy. The company recognizes the urgent need to address climate change and reduce greenhouse gas emissions, and is investing in a range of initiatives to achieve its goals. South32's commitment to responsible mining practices and engagement with local communities also demonstrates its commitment to environmental and social responsibility.
