Key takeaways:
- Integrating sustainability from concept to closure strengthens mining operations by enhancing competitiveness and improving long-term resilience
- Strategic water management and climate risk readiness are critical for long-term operational continuity
- Bridging sustainability strategy and execution improves efficiency, transparency, and stakeholder trust
Over the past decade, sustainability in the mining industry has evolved from a primarily compliance-driven approach into a strategic component that directly influences project viability, financing, and competitiveness. Today, topics such as water resource management, community engagement, climate resilience, and carbon footprint reduction are deeply integrated into technical and financial decision-making from the earliest stages of project development.
This evolution reflects a broader shift in how project success is defined. Mining projects are now evaluated not only on technical and economic performance, but also on their ability to manage environmental and social risks, respond to changing regulations, and demonstrate long-term resilience. A double materiality lens is increasingly applied, evaluating both project impacts and how sustainability-related factors influence financial outcomes. Climate risk, water availability, and social license are now key financial considerations, directly affecting timelines, capital allocation, operating costs, and overall project viability. As a result, sustainability has become a core component of risk management, operational continuity, and investment confidence.
International frameworks such as the International Council on Mining and Metals (ICMM) Principles and International Finance Corporation (IFC) Performance Standards, are helping shape this transition alongside emerging approaches to climate-related and non-financial risk management. Sabrina Galli, Environmental Engineering Specialist at Ausenco, explains: “Sustainability is no longer a defensive exercise—it now plays a key role in risk management, operational resilience, and long-term access to capital.”
Sustainability from the start
The early stages of a project, particularly conceptual and prefeasibility studies, are critical in shaping its future performance. At this phase, it is still possible to significantly influence outcomes, building adaptability into the project to respond to regulatory or market changes. Based on Ausenco’s experience, most of the environmental, social, and economic impacts are identified during these initial phases. This aligns with IFC PS1 principles and ICMM guidelines.
Embedding environmental and social specialists into early project risk assessments and multidisciplinary workshops can help identify sustainability risks and opportunities before they become costly design or execution challenges. Hilary Evans, Sustainability Project Integration Lead notes: “Some of the most valuable sustainability discussions happen during multidisciplinary risk workshops, where engineering, operations, environmental, and social perspectives come together early enough to influence project decisions.” Rather than focusing only on impact identification, early-stage sustainability integration helps uncover financial risks and opportunities that influence project viability. Decisions around facility location, water management strategies, and technology selection influence not only environmental performance, but also permitting, community relationships, operational resilience and long-term costs.
Water strategy plays a fundamental role. Assessing resource availability, watershed interactions, regulatory requirements, and future expansion scenarios during conceptual engineering can reduce uncertainty, optimise infrastructure, and safeguard operational continuity. Increasingly, it is a best practice to incorporate forward-looking climate scenario modelling and projected forecasts alongside historical data to better anticipate long-term variability and risks. As Marcelo Navarrete, Senior Water Resources Specialist at Ausenco, notes: “Water strategy can no longer be assessed solely from a compliance perspective; it is now a critical variable for the sustainable development of projects.”
For example, defining early-stage strategies such as water recirculation or the use of alternative sources may require higher upfront investment, but can significantly reduce operational risks and the need for redesign in later stages. For a mining client in northern Chile, we supported the evaluation of different alternatives to optimise the construction and performance of dewatering wells. Through a multi-criteria analysis combined with operational experience and applied research, we were able to identify opportunities to reduce uncertainties, optimise execution timelines, and strengthen decision-making.
Bringing the gap: from strategy to execution
One of the most common challenges in integrating sustainability is bridging the gap between strategic commitments and practical implementation. As projects progress into detailed engineering and construction, sustainability goals must be translated into clear, measurable, and verifiable technical criteria embedded in design specifications, procurement processes, and construction standards.
Indicators such as water consumption, energy efficiency criteria, emission levels, and waste management help align multidisciplinary teams and enable a more effective balance between CAPEX, OPEX, and environmental performance. They also provide a basis for quantifying sustainability-related risks and opportunities, enabling their integration into project controls, financial models, and investment decisions.
During the construction phase, governance becomes particularly critical. Sustainability commitments established during design must be translated into practical execution through procurement strategies, contractor requirements, site controls, and performance monitoring. Embedding sustainability criteria into contracts and project execution helps improve accountability across contractors and suppliers, supports faster and more informed decision-making, and reduces the risk of deviations during construction. In this context, sustainability becomes not only a reporting exercise, but a practical tool for improving project delivery, operational resilience, and stakeholder confidence.
Drawing on her experience, Hilary notes: “In practice, the projects that perform best are those where sustainability expectations are clearly integrated into contractor responsibilities, project controls, and day-to-day decision-making from the start. This alignment helps reduce rework, manage change more effectively, and keep teams accountable throughout execution.”
In the operational phase, early integration of sustainability translates into more resilient projects, capable of adapting to regulatory, climatic, and social changes. Efficient resource management, combined with continuous improvement and defined change management processes, helps reduce contingencies and supports sustainable performance over time.
Setting your project up for success and long-term performance
Integrating sustainability throughout the project lifecycle means addressing closure considerations from the earliest stages. Designing with closure in mind helps reduce environmental liabilities, optimise costs, and deliver lasting positive outcomes for communities and the surrounding environment.
At the same time, aligning with robust non-financial reporting and sustainability-related financial disclosure frameworks, such as the Global Reporting Initiative (GRI) standards, the International Sustainability Standards Board (ISSB/IFRS S2), and emerging standards like the Taskforce on Nature-related Financial Disclosures (TNFD), enhances transparency, traceability, and trust among stakeholders.
“When sustainability strategy is integrated and shared across both site and corporate teams, it becomes a real competitive advantage,” says Sabrina Galli. “It enables organisations to anticipate regulatory changes, improve efficiency, and strengthen their social license to operate.” In this context, digitalisation and performance data play a key role by supporting better decision-making, driving continuous improvement, and advancing decarbonisation initiatives without compromising productivity.
In a project in Latin America, we acted as strategic partners in the harmonisation of sustainability standards, translating them into practical operational frameworks in Chile and Argentina. The work included the development of a comparative matrix between local and international standards, along with a gap analysis that enabled the identification of risks, assessment of impacts, and defined improvement actions. One of the main challenges was translating regulatory requirements and general guidelines into practical actions applicable to projects. Clear foundations were established for sustainability implementation that was measurable and aligned with current and future operational needs, strengthening transparency and social license to operate.
Looking ahead, trends such as operational decarbonisation, strategic water management, resilience to climate variability, informed Indigenous consent, and the adoption of Mining 5.0 technologies will continue to evolve industry standards. In this environment, sustainability is a baseline requirement for resilient projects, where efficient and traceable resource management becomes a key enabler of operational continuity and long-term value.
