Our commitment to achieving a Net Positive Impact (NPI) on biodiversity provides the basis for how we manage our nature-related impacts, risks and opportunities.
Aligning to the ICMM No Net Loss or Net Gain approach, we focus on implementing the mitigation hierarchy to ensure that our positive contributions to biodiversity and ecosystems outweigh residual negative impacts. This is in line with our broader sustainability objectives to focus efforts on restoration and enhancing natural habitats.
In 2018, as part of our original Sustainable Mining Plan, we committed to achieving Net Positive Impact by implementing the mitigation hierarchy – mitigating, rehabilitating, and offsetting where we could not avoid disturbance.
Our previous Net Positive Impact commitment applied a static 2030 target across the business. However, the continuous development of the measurement of Net Positive Impact has highlighted that site-level impacts are dynamic and shift over time. As a result, we have since recognised that applying a fixed target across all operations does not reflect this variability. Instead, we are targeting maintaining a continuous, externally validated pathway to Net Positive Impact on biodiversity throughout the life of our assets.
The original commitment relied on achieving NPI in aggregate which allowed biodiversity losses at one site to be offset by gains elsewhere in the portfolio. Our revised approach, detailed in our new Sustainability Strategy (February 2026), reflects the variability across all operations and includes the operation and context-specific local requirements as agreed with regulators and stakeholders.
The NPI baseline year remains 2018, serving as the reference point for measuring change. Each site will use the baseline condition and demonstrate, over time, that it is on a credible and externally verified pathway to achieving NPI. This will include setting intermediate milestones and delivering local, time-bound actions aligned with the Global Biodiversity Framework (GBF) and other site-specific priorities. This pathway approach allows us to track progress from 2018 through the life of the asset. The revised target emphasises each site’s responsibility to deliver NPI for biodiversity at operations and reflects our broader strategy to contribute towards a nature positive future. Demonstrating that a site is on a credible pathway to NPI throughout the life of the asset signals a sustained, long-term commitment to biodiversity and responds to societal expectations for holistic, systemic action.
We measure our progress towards Net Positive Impact consistently across diverse geographies and ecological contexts by applying the single, Group-wide biodiversity metric of Quality Habitat Hectares (QHH).*
QHH was co-developed with international conservation organisation Fauna & Flora, to ensure the measure was credible and robust. QHH enables a standardised and objective assessment of the quantity (hectares), and quality of ecosystems impacted in and around our operations. By using this approach, we can quantify actions to avoid disturbance, reduce and restore habitats, and identify opportunities to contribute to nature positive outcomes wherever we operate, as well as assess the timing and cost to implement actions.

The QHH metric provides a clear, comparable understanding of habitat condition and extent, enabling us to quantify both losses and gains over time. As it develops it will also be integral to how we plan, operate and close our assets. Each operation will use its QHH trajectory to guide the development of its bespoke Biodiversity Management Programmes, determine the effectiveness of mitigation measures and inform decisions about when, where and how we invest in restoration and conservation.
Although QHH remains our principal metric, we continue to monitor developments in global biodiversity accounting and policy. As nature-related standards evolve, we will consider complementary approaches where they enhance transparency or strengthen decision-making.
* IUCN’s Net Positive Impact Approach is centred on the application of the mitigation hierarchy – avoid, minimise, restore and offset impacts – supported by measurable indicators. The Quality Habitat Hectares (QHH) methodology offers a consistent framework for quantifying both losses and gains arising from project activities.
