Introduction - Our approach to sustainability

We’re delivering positive environmental outcomes, minimising our footprint and building resilience. Our focus is clear: Climate, Nature, and Water.

From decarbonising operations to restoring ecosystems and safeguarding catchments, we embed sustainability through integrated planning, partnerships, technology and a culture of accountability – so our host communities and the planet thrive together.

Navigate our Sustainability Strategy

Use this model to learn about the themes and focus areas within our Sustainability Strategy.

Key focus areas and associated aims and targets

We are reducing emissions, improving energy efficiency to decarbonise our value chain.

Our goal:


  • Reduce operational emissions by 28% by 2030 (vs. 2020)

We aim for nature‑positive outcomes, protecting biodiversity and ecosystem services while rehabilitating land and planning for positive legacies.

Partnerships and science‑based methods shape action on habitats, invasive species control and landscape‑level restoration.

Our goal:


  • Maintain a continuous, validated pathway to Net Positive Impact on biodiversity throughout the life of our assets

We protect, preserve and restore our water catchments, advancing water stewardship. Through adaptive management and collaboration with stakeholders, we support resilient operations and communities.

Our goals:
Support equitable water access and ecosystem resilience through surplus water management and groundwater recharge

Our thematic areas and milestones:

  • Mitigation of shared water challenges
    • 2026 – 2030: Diversion of surplus/excess water volumes into the Water Supply Scheme (WSS)
    • 2026 – 2030: Withdrawals of treated sewage effluent from the Gamagara Municipality wastewater treatment works.
  • Replenishing of groundwater table/levels through artificial aquifer recharge.
    • 2026 – 2030: Continue aquifer recharge programmes in the catchments in which we operate.

Powering Sishen and Kolomela with Renewables

The Northern Cape hosts some of Africa’s strongest solar and wind resources which hlep strengthen renewable availability for generation and wheeling to industrial off takers like our mines. Our climate pathway targets a 28% reduction in operational GHG emissions by 2030 (from a 2020 baseline) - making clean electricity a cornerstone of our decarbonisation plan

To reduce our scope 2 emissions, we are participating in Anglo American’s RREE initiative. As part of this initiative, we are developing a 63 MW solar PV plant at Sishen that will reduce our scope 2 emissions by approximately 30% by late 2026.

We are further pursuing an 11 MW renewable wheeling contract at Kolomela, which is expected to reduce our scope 2 emissions by approximately 85% by 2026.

What this means: Our on‑site generation reduces reliance on carbon‑intensive grid power and buffers the operation against power‑supply volatility—while wheeled renewables scale the decarbonisation impact across our sites.

We continue to support energy security through relevant forums – Energy Intensive Users Group of Southern Africa, the Minerals Council, and Business Leadership South Africa as Eskom works to improve generation availability and transmission capacity in the Northern Cape.

By pairing on‑site solar at Sishen with wheeled wind and solar through Envusa Energy, we’re turning ambition into action – our footprint today while building the platform for our ambitions. We’ll keep executing projects, partnering across the system, and navigating Northern Cape grid constraints responsibly – so our mines run on cleaner, more reliable power and our climate progress endures.

Our ambition is to deliver positive environmental outcomes, minimise out footprint and achieve carbon neutrality.

We’re integrating water stewardship, nature‑positive rehabilitation and tailings excellence across our operations so that weather events, rehabilitation projects and responsible tailings management work together to deliver positive environmental outcomes. Guided by IRMA insights and our adaptive water management approach, we protect, preserve and restore shared catchments, while our GISTM‑aligned tailings practices strengthen safety, transparency and long‑term land resilience for our operations and host communities. This is how we turn strategy into measurable impact – positioning us for resilience, and championing healthy environments in practice.

Our integrated approach

  1. Adaptive Water Management (AWM)
  2. We introduced site‑level AWM measures – water modelling, risk-based dewatering, rain‑readiness planning, and enhanced quality and quantity monitoring - to anticipate extremes and improve water reliability for our operations and host communities.

  3. Restoring biodiversity and ecosystem services
  4. We apply science‑based restoration to rehabilitate disturbed land, manage invasive species and align rehabilitation with conservation priorities. This supports our ambition for nature‑positive outcomes over the life of our assets and complements progressive closure planning disclosed in our annual sustainability report.

  5. Tailings stewardship and land stability
  6. At both our operations, our GISTM (Global Industry Standard on Tailings Management) programme formalises risk controls, surveillance and emergency preparedness for our TSFs. Our 2025 GISTM Disclosure details facility characteristics, consequence classification and conformance status, evidencing our systematic approach to safe, stable and progressively rehabilitated tailings facilities.

  7. Physical Climate Change Risk and Resilience (PCCRR)
  8. Our PCCRR approach quantifies acute and chronic climate hazards – intense rainfall, flooding, lightning, high winds, heat and prolonged drought – and maps our exposure across mining value chain.

    In looking at sensitive habitats and receptors, host communities and the broader value chain, we are looking towards enhancing our adaptation measures. Our approaches include:

    • These include adaptive water management (water‑balance modelling, stormwater attenuation, flood routing and aquifer recharge),
    • Nature‑based solutions (such as wetland/riparian restoration and erosion control), and
    • Tailings and slope design reviews aligned to GISTM.

We strengthen readiness through redundancy and early‑warning monitoring (rain, flow, piezometers, heat and lightning), plus heat‑stress ergonomics and shift protocols, and scenario‑based drills.

Our integrated approach transcends resource management, aligning environmental and social outcomes with long‑term value. We are contributing to the foundation for resilient operations and host communities that can sustain industries, communities and ecosystems for generations to come. This is responsible mining in practice.
