Copper is a key metal used in electric vehicles and charging infrastructure. It is an excellent conductor of electricity, so as the world moves towards electrification, copper will increasingly be used in power-related infrastructure, including renewable energy. Copper is also used in kitchen cookware and plumbing as it conducts heat well and has antimicrobial properties.
In FY22 we acquired an interest in our first operating copper mine - a conventional open-cut copper mine in the prolific Antofagasta region in Chile, which transitioned to 100 per cent renewable electricity supply in FY23.
70.7kt
FY23 copper production
Silver is used in solar panels due to its superior electrical conductivity, and is also used to make medical appliances and consumer electronics.
Lead is used in renewable energy storage systems.
Zinc protects metals against corrosion and will play a key role in green infrastructure development as a protective coating for wind turbines and solar panels. In solar panels zinc oxide coatings help achieve higher energy conversion.
We are a large producer of silver-rich lead concentrate and zinc concentrate.

Currently there is no viable alternative to metallurgical coal in the steelmaking process. The use of high-quality metallurgical coal that we produce supports greenhouse gas emissions reduction targets in the steel industry through improved blast furnace efficiency, when compared with lower-quality metallurgical coal. Growth in steel demand is anticipated for green infrastructure development and vehicle electrification, as well as for the establishment of new steel capacity in emerging markets.
We produce premium-quality, hard coking coal for domestic and export steel markets.
5,497kt
FY23 metallurgical coal production
Manganese is used to improve the quality and strength of steel in major infrastructure such as hospitals, office towers and bridges. Manganese also has the potential to displace cobalt in lithium-ion batteries, with demand for manganese-rich cathode chemistries expected to grow.
We are well positioned to meet future demand as we are the world’s largest producer of manganese and our Hermosa project has the potential to produce battery-grade manganese.

Performance snapshot
Our approach to climate change is integrated with our strategy and is designed to protect and unlock long-term value, build operational resilience, and enhance our competitiveness in a low-carbon world.
As a global mining and metals company, we have an important role to play in responding to the risks and opportunities of climate change: to produce commodities that are critical in the transition to a low-carbon world; and to do so in a way that seeks to minimise our impact.
Our approach
We support the objectives of the Paris Agreement and have a long-term goal¹ to achieve net zero greenhouse gas (GHG) emissions across all scopes (i.e. Scope 1, 2 and 3) by 2050.
We also have a medium-term target² to halve our operational GHG emissions by 2035 from our FY21 baseline³.
We are working to deliver our goal and target as described in our Climate Change Action Plan (CCAP) which was published in September 2022. The Addressing Climate Change section of our Sustainable Development Report (Pages 87-117), along with our Sustainability Databook, provides our first annual update of progress in delivering our CCAP.
Our approach to climate change is aligned to our purpose and integrated with our strategy, and is focused on:
- Reshaping our portfolio to the commodities that are critical in the transition to a low-carbon world
- Decarbonising our operations, with a focus on the four operations within our portfolio which account for the majority of our GHG emissions profile
- Understanding and responding to the potential physical impacts of climate change on our business to build operational resilience
- Working with others to innovate and address shared challenges across industry, and to decarbonise the value chain
¹ ‘Goal’ is defined as an ambition to seek an outcome for which there is no current pathway(s), but for which efforts will be pursued towards addressing that challenge, subject to certain assumptions or conditions.
² ‘Target’ is defined as an intended outcome in relation to which we have identified one or more pathways for delivery of that outcome, subject to certain assumptions or conditions.
³ FY21 baseline adjusted to exclude GHG emissions from SAEC and TEMCO, which were divested in FY21.
⁴ Low-carbon refers to lower levels of GHG emissions when compared to the current state. Where used in relation to South32’s products or portfolio, it refers to enhancement of
existing methods, practices and technologies to substantially lower the level of embodied GHG emissions as compared to the current state
RESHAPING OUR PORTFOLIO
Our commodity mix today is very different from that of 2015 when South32 was first established. We have exited carbon intensive and lower returning businesses, added copper and grown our share of low-carbon aluminium production.
FY23 at a glance
- Delivered 14 per cent growth in aluminium production and 17 per cent growth in other base metals production, benefitting from our investments in copper and low-carbon aluminium
- Advanced study work for the Hermosa project’s Taylor silver-lead-zinc and Clark battery-grade manganese Deposits
- Updated our 1.5°C scenario and reassessed the resilience of our portfolio under a rapid global transition
The graphic below shows how our commodity mix has evolved from FY16 to FY23. In FY23, we delivered 14 per cent growth in aluminium production and 17 per cent growth in other base metals production, as we realised the benefit of FY22 transactions that increased our exposure to these commodities.
OPERATIONAL DECARBONISATION
Over 90 per cent of our operational GHG emissions are generated by four operations. Our decarbonisation initiatives are primarily focused on these operations to support a significant reduction in our operational GHG emissions and deliver our medium-term target.
FY23 at a glance
- Commenced conversion of first coal-fired boiler to natural gas as a transitional step at Worsley Alumina, with an estimated abatement of up to 205,000 tonnes of CO2-e per year
- Converted 18 per cent of pots at Hillside Aluminium to AP3XLE energy efficiency technology, and completed four of five EnPot trials
- Commenced detailed design and execution planning for a commercial scale trial of CSIRO ventilation air methane mitigator (VAMMIT) technology at Illawarra Metallurgical Coal (IMC)
Our reported Scope 1 and Scope 2 GHG emissions for FY23 were 21.0 Mt CO2-e, a 0.2 per cent increase from our FY22 GHG emissions and a 1.6 per cent increase from our FY21 baseline.
Scope 1 GHG emissions from activities at our operations increased in FY23 by 0.5 Mt CO2-e, while there was a decrease of 0.4 Mt CO2-e in GHG emissions from electricity used by our operations (Scope 2).
¹ FY21 baseline adjusted to exclude GHG emissions from SAEC and TEMCO, which were divested in FY21
² FY21 GHG emissions adjusted to exclude GHG emissions from SAEC and TEMCO, which were divested in FY21.
³ The sum of the categories may vary to the total figure due to rounding.
SCOPE 3 GHG EMISSIONS
Scope 3 GHG emissions include those associated with upstream activities, such as embodied emissions in goods and services we use, and downstream activities, such as the processing and end-use of our products by our customers.
In FY23, almost 90 per cent of reported value chain GHG emissions were attributable to the downstream use and processing of our products, in particular the processing of alumina to manufacture aluminium ingots and use of metallurgical coal to make steel.
FY23 at a glance
- Commenced implementation of a shipping freight pricing incentive tied to carbon emissions performance of vessels
- Reviewed the decarbonisation goals and strategies of key suppliers and commenced engagement to develop potential new partnerships

Note: Estimate of Scope 3 GHG emissions by commodity
are based on processing and use of sold products, and apportionment of other categories.
A description of Scope 3 GHG emission categories and methodologies is available in our 2023 Sustainability Databook
PHYSICAL CLIMATE RISKS
Physical climate risks are driven or intensified by weather, climate variability or climate change. They include acute risks, resulting from increased frequency or severity of extreme weather events (e.g., drought or flood events) and chronic risks, resulting from longer-term changes in climate patterns (e.g., sustained higher temperatures, sea level rise).
Physical climate risks have the potential to affect the integrity and performance of our equipment and infrastructure, compromise productivity, and disrupt business continuity (including our supply chain activities). There may also be broader environmental and socio-economic impacts on key stakeholders, including local communities.
FY23 at a glance
- Commenced incorporating the outcomes of our FY22 physical impacts of climate change assessment into our material risk reviews, including supply chains
- Considered physical climate risks in our life of operation plans (including closure planning)
- Embedded physical climate risk into South32's broader governance framework, including risk, integrated planning and environment
Our Sustainable Development Report also includes information about our Governance and Risk Management regarding climate change, which can be found on pages 115-117.
