Committed to the planet
As a custodian of Western Australia's precious metals value chain, The Perth Mint recognises its responsibility to minimise environmental impacts and is committed to responsible resource use, improving energy efficiency and reducing carbon emissions.
By embedding these considerations into our operations, we support State Government priorities, respond to stakeholder expectations and help ensure our business remains resilient into the future.
We aim to balance environmental, social and economic considerations in a way that protects and enhances long-term value for the State, our customers, our employees and the community.
Management systems
We have ISO14001 (Environmental Management Systems) and ISO 45001 (Occupational Health and Safety Management Systems) certification recognising our Integrated Management System across our East Perth and refinery sites.
Greenhouse gas emissions and energy
We have elected to voluntarily report scope 1 and scope 2 greenhouse gas emissions following the Australian National Greenhouse and Energy Reporting (NGER) methodology as a measurement framework.
We apply an operational control approach to set our organisational boundary (our emissions reporting boundary). This means our scope 1 and scope 2 emissions comprised activities over which we have direct operational control.
We engage Bureau Veritas to perform independent assurance reports.

Climate change
As part of our commitment to integrate climate-related considerations into governance processes, we have validated the findings of our 2024-25 first-pass climate risk assessment with internal stakeholders, confirming key climate-related risks and opportunities across the business.
Waste management
Our Waste Management Strategy and site-specific Waste Management Plans guide a consistent approach to waste avoidance, resource recovery and operational efficiency across our operations. We have targeted actions to reduce waste generation, improve resource recovery outcomes and support continuous improvement.
