Healthy ecosystems support people, livelihoods and economic prosperity. Responsible environmental management is essential to sustaining these shared resources over the long term.
Biodiversity underpins the ecosystems that support communities and the economy. Mining activities may intersect with areas of high ecological value, and our operations and adjacent communities both depend on services that ecosystems provide, such as habitat condition, clean water and air, erosion control and climate regulation. We’re committed to protecting biodiversity and we aim to achieve no net loss (NNL) at our managed operations by the end of closure. This means striking a balance between biodiversity losses and gains.
Our Environment Standard outlines the requirements to protect priority biodiversity features for our managed assets. The standard covers the requirement to implement the mitigation hierarchy (avoid, minimise, restore, offset) throughout the mining lifecycle. This includes baseline and impact assessments, monitoring, and adaptive management.
As ICMM members, we report our progress against the commitments outlined in the ICMM Nature Position Statement. At an asset level, we also focus on implementing applicable regulatory, lender (for example International Finance Corporation Performance Standard 6 (IFC PS6)) or other commitments.
We have developed a risk framework that provides a consistent approach to how we identify, assess, manage and communicate biodiversity-related risk across our portfolio. It builds on our Environment Standard and includes a library of controls. The framework aims to verify that biodiversity management is both operationally effective and strategically aligned with our environmental commitments. Biodiversity is also incorporated within our principal environment risk. Our framework covers 2 categories:
We use the framework to understand our risk exposure across our portfolio at a point in time. We also compile biodiversity data for our managed assets each year. Visit the Sustainability Fact Book for more detailed information. The mitigation hierarchy guides our approach to managing environment and biodiversity risks and impacts across our global portfolio. This includes:
Avoidance
Minimisation
Rehabilitation
Offset
We collect data on biodiversity and receiving environments across our operations, some of which is shared in our Sustainability Fact Book.
Examples:
These are some of our partnerships that focus on delivering biodiversity outcomes:
Sustainability reporting
No Net Loss (NNL): the point at which nature losses occurring as a result of our activities are balanced by proportional gains (through rehabilitation, restoration or conservation), relative to a defined baseline state.
Baseline: for existing operations, NNL is typically measured against a baseline of 2020 or earlier; for new operations and expansions, it is measured against a pre-operational baseline.
Mitigation Hierarchy: used to achieve NNL through first avoiding impacts, then minimizing, followed by rehabilitation of degraded areas, and finally use of offsets or conservation gains to balance any residual losses.
