With the federal election behind us, Australia stands at an important crossroads for environmental reform and climate policy. Over the past term, we saw the Government attempt a bold overhaul of environmental laws and climate frameworks – many of which faced roadblocks in Parliament. As the newly re-elected Government settles in, the direction it takes now will have a lasting impact on the country’s climate commitments, biodiversity outcomes, and transition to renewable energy.

While details remain to be seen, now is a key time for businesses, industry leaders and environmental practitioners to stay engaged and contribute to consultations as these policies evolve.

Where Are We Headed?

Here are the major themes and expectations shaping the road ahead:

• Climate Targets: The Government is holding the course on its net zero by 2050 ambition and 2030 emissions reduction target (43% below 2005 levels). The Climate Change Authority will guide the setting of a 2035 target, as required under existing law.
• Renewable Energy Push: Building on the Powering Australia Plan, the target remains for renewables to provide 82% of the National Electricity Market by 2030. The Government has pledged a further $8 billion in investment via the Clean Energy Finance Corporation to accelerate the shift to low-emissions technology – firmly opposing nuclear as an alternative.
• Nature Positive Reforms – Still in Play?: After ambitious reforms to the Environment Protection and Biodiversity Conservation (EPBC) Act stalled during Labor’s last term, it’s unclear how far the next wave of environmental reforms will go. That said, Prime Minister Albanese has confirmed that reform is still on the agenda, albeit in a revised form. Importantly, the commitment to biodiversity protection remains, supported by a $262 million pledge over five years to meet the ’30 by 30′ conservation target – protecting 30% of Australia’s land and marine areas by 2030.

A Look Back: Progress and Setbacks

In 2022, the Government outlined its Nature Positive Plan – the most significant proposed revamp of federal environmental laws since the EPBC Act came into effect over two decades ago. The reforms were based on Professor Graeme Samuel AC’s independent review and promised to reshape environmental governance, impact assessment, and biodiversity protection.

Only a fraction of this agenda was implemented:

• Nature Repair Market: Launched on 1 March 2025, this world-first legislated biodiversity credit scheme allows landholders and organisations to earn and trade biodiversity certificates by undertaking verified conservation and restoration activities.
• Water Trigger Expansion: Reforms extended the ‘water trigger’ under the EPBC Act to apply to all unconventional gas projects, strengthening protections for vital water systems.

Other key components – like the proposed creation of Environment Protection Australia and Environment Information Australia – were introduced to Parliament but ultimately shelved in early 2025 due to lack of Senate support.

Looking Forward: What Should We Expect?

Although the full legislative reform agenda remains uncertain, the outcome of the election appears to have strengthened Labor’s Senate position, which could open the door for further environmental legislation.

For now, we can expect:

• Continued momentum on renewable energy and emissions reduction;
• Selective engagement with environmental law reform, likely in consultation with states, industry, and environmental groups;
• Increased funding and focus on biodiversity outcomes through programs like the Nature Repair Market and 30 by 30 initiatives.

Why It Matters

The decisions made in the next few months will shape how Australia manages its natural assets, responds to climate risk, and positions itself in a decarbonising global economy. For businesses, there’s a real opportunity – and responsibility – to align with these shifts. Staying informed, participating in consultations, and preparing for regulatory changes will be key.

The Joint Ore Reserves Committee (JORC) has released its draft 2024 Code for public consultation, setting the stage for a step-change in the way Australia’s mining and resources industry communicates project viability and value.

This isn’t just a technical update—it’s a fundamental realignment with the modern expectations of investors, regulators, financiers, and communities. The proposed changes embed Environmental, Social and Governance (ESG) considerations, mine closure planning, and the structured use of multidisciplinary specialists into the core of public reporting for Exploration Results, Mineral Resources, and Ore Reserves.

Gone are the days when modifying factors could be treated as a footnote. The draft JORC Code signals that a project’s success is not just defined by geology and economics, but also by its social licence, environmental footprint, regulatory credibility, and long-term legacy.

Key Updates in the Draft JORC Code (2024)
1. Mandatory ESG Considerations in Public Reporting

The most prominent update is the introduction of mandatory ESG evaluation in all stages of reporting. ESG is now positioned as a core modifying factor—placing the onus on Competent Persons (CPs) to either directly assess, or transparently acknowledge, the ESG risks and opportunities that influence project outcomes.

What this means in practice:

• Environmental: Assessment of biodiversity impacts, water security, tailings and waste management, land disturbance, climate-related risks (e.g. flooding or bushfire), greenhouse gas emissions, and rehabilitation obligations.
• Social: Consideration of local and Indigenous community expectations, cultural heritage protections, landholder access, workforce capacity, housing impacts, and the project’s social licence to operate.
• Governance: Transparency regarding permitting pathways, compliance status, regulatory uncertainty, land tenure, and alignment with company governance structures and ESG performance frameworks.

Importantly, the Code does not expect every CP to be an ESG expert—but it does expect CPs to understand when ESG risks are material, and to engage recognised Specialists to fill those knowledge gaps. These ESG aspects will need to be explicitly described, not just assumed.

2. Mine Closure Is a Core Part of Reserve Evaluation

Another pivotal change is the formal integration of mine closure planning and liabilities into the Reserve estimation process. The Code makes clear that closure is not a distant event—it is a present-day risk that must be modelled and costed.

Competent Persons will now need to:

• Demonstrate that closure costs (progressive and final) have been quantified and factored into financial modelling
• Identify whether closure plans are approved, under development, or contested
• Account for the feasibility of relinquishment and any long-term monitoring obligations
• Assess how post-mining land uses align with community and regulatory expectations
• Consider whether residual risk could materially alter project viability, either technically or reputationally

Closure planning is no longer optional. It must now be aligned with life-of-mine scheduling, project valuation, and the narrative presented to markets.

3. Specialist Input is Mandatory, Not Just Preferred

The draft Code introduces an explicit requirement: if the Competent Person lacks competence in an area material to the project’s outcome, a named and qualified Specialist must be engaged, and their input clearly documented in the Public Report.

This includes (but is not limited to):

• ESG
• Tailings and water management
• Geotechnical risk
• Heritage and community engagement
• Closure planning
• Hydrogeology or groundwater modelling

This promotes transparency, prevents unqualified commentary, and ensures that assumptions are properly interrogated. The use of Specialists must be scoped, sourced, and declared—in other words, integrated into the reporting framework, not appended as an afterthought.

IEMA’s Role: Helping You Adapt and Thrive

At IEMA, we see this new Code as a welcome evolution, but not one that needs to be over complicated or adding multiple layers to the process.

A quiet revolution is brewing in the regions of New South Wales. The kind of revolution that could redefine what we do with the thousands of hectares of land left behind by decades of mining — and what kind of future we offer to the communities who live on it.

A new report from the NSW Legislative Council, Report No. 53 – Beneficial and Productive Post-Mining Land Use, argues that mine closure doesn’t have to mean abandonment. Instead, it lays out a bold case for something far more ambitious: turning former mine sites into engines of regional renewal.

“This is not just about planting grass and walking away,” the report suggests. “It’s about building energy precincts, housing, advanced manufacturing hubs, biodiversity corridors and even eco-tourism zones.”

The stakes are high. More than 30 coal mines are expected to close in NSW by 2040. Without reform, the state risks leaving behind stranded infrastructure, frustrated communities and squandered economic potential. But with the right changes? A very different picture emerges.

The Problem with the Status Quo

At the heart of the issue is a planning and regulatory system that hasn’t kept pace with the energy transition.

Under current laws, mine rehabilitation focuses almost entirely on environmental stability. The goal is to return land to a “safe, stable and sustainable” state — typically defined decades in advance, long before local economies and energy markets started shifting.

That rigidity, the report argues, is now a serious liability.

What’s Being Proposed

The committee’s recommendations, grounded in 77 submissions and six public hearings, offer a blueprint for change:

• A full legislative review of the Mining Act 1992 and Environmental Planning and Assessment Act 1979 to support adaptive land use.
• Creation of Place Delivery Groups to coordinate regional planning and unlock development.
• Appointment of a Mine Rehabilitation Commissioner to lead cross-government efforts and cut through complexity.
• Incentives to support innovation — especially clean energy, circular economy projects and reuse of infrastructure.
• A skills audit and reskilling strategy to support communities as workforces shift from mining to emerging industries.

What Stakeholders Said: Insights from 77 Submissions

The NSW Legislative Council’s inquiry into post-mining land use received 77 submissions from a wide range of stakeholders — from local councils and mining companies to environmental groups and clean tech innovators. Here’s a breakdown of the key voices and their messages:

• Local Councils Representative submitters: Muswellbrook, Singleton, Lake Macquarie, Cessnock, Narrabri, Wollondilly Called for place-based planning models, zoning reform, infrastructure reuse, and earlier engagement in post-mining land use decisions.
• Mining Companies Representative submitters: BHP, Glencore, Yancoal, MACH Energy, Idemitsu Sought streamlined development consent processes, flexibility to modify final landforms, and greater support for repurposing mining assets.
• Industry Associations Representative submitters: NSW Minerals Council, AMEC, Property Council of Australia, Business Hunter Advocated for coordinated leadership, regulatory certainty, and investment-friendly frameworks to unlock beneficial reuse.
• Community and Environmental Groups Representative submitters: Lock the Gate Alliance, Nature Conservation Council, Wollar Progress Association Emphasised the importance of transparency, biodiversity restoration, community voice, and cultural heritage in land use planning.
• Research and Academia Representative submitters: CSIRO, CRC TiME, University of Newcastle (Institute for Regional Futures) Highlighted the need for evidence-based planning, regional economic visioning, integrated land strategies, and demonstration projects.
• Clean Tech and Energy Startups Representative submitters: Green Gravity, Gravitricity, ZEN Energy Proposed using mine voids and infrastructure for pumped hydro, gravity-based storage, hydrogen production, and clean energy innovation.
• Workforce & Unions Representative submitters: Mining and Energy Union, BCR Advisory, Australian Workers’ Union Stressed the urgency of workforce planning, job security, and retraining opportunities to support just and inclusive transitions.

What Becomes Possible: A Future-Focused Vision

By implementing the recommendations of this report, NSW can unlock transformational opportunities in six key domains:

1. Clean Energy Precincts Mine voids repurposed for pumped hydro. Solar and wind farms built on cleared land. Hydrogen hubs co-located with industrial users. Impact: Accelerate net-zero transition and attract regional investment.
2. Circular Economy and Critical Minerals Tailings reprocessed for rare earths. Recycling hubs established on industrial footprints. Old rail and road infrastructure repurposed for logistics. Impact: Create resilient supply chains and regional manufacturing jobs.
3. Regenerative Landscapes and Cultural Renewal Buffer zones rewilded. Country co-managed with Traditional Owners. Eco-tourism destinations built around heritage. Impact: Restore nature, empower culture, and diversify local economies.
4. Liveable Regional Development Zoning updated to allow new housing, health, and education precincts. Infrastructure investment aligned across government. “Legacy land” transformed into new communities. Impact: Ease regional housing pressure and boost construction sectors.
5. Reskilling and Employment Transitions Training centres launched in mining towns. Retraining tailored to new sectors like renewables and agritech. Long-term careers created — not just temporary jobs. Impact: Prevent social dislocation and build long-term regional resilience.
6. Global Leadership in Transition Strategy NSW becomes a case study in successful coal transition. Best practices exported to other jurisdictions. Funding, partnerships and R&D attracted through reform. Impact: Cement the state’s reputation as a leader in the net-zero economy.

Who Will Invest in Former Mine Sites — And How Do We Attract Them?

Reimagining post-mining land as a foundation for future industries will take more than vision — it will take investment. The potential is clear: clean energy hubs, circular economy facilities, industrial precincts, housing, tourism, and nature-based regeneration. But who funds these transformations, and how do we bring them to the table?

The answer: a diverse and growing network of domestic and global investors are actively looking for the kinds of opportunities that post-mining land presents — provided the groundwork is laid.

Energy and Infrastructure Investors

Renewable energy developers and infrastructure funds are seeking large, strategically located land parcels with access to the grid. Former mine sites, especially those with existing infrastructure like substations or water access, are ideal for solar, wind, pumped hydro, and hydrogen projects.

What these investors need is policy certainty, streamlined planning approvals, and a clear pathway to access and develop the land. With the right coordination, post-mining land can play a central role in delivering on Australia’s net-zero commitments.

Circular Economy and Resource Recovery

Another class of investors is emerging from the circular economy and resource recovery sectors. These firms are interested in repurposing mine tailings, recovering critical minerals, and establishing recycling hubs. Industrial footprints and rail-linked sites offer particular appeal — especially if state and local planning instruments support their reuse.

Engaging these players requires data transparency, site readiness, and demonstration of viable reuse models through pilot programs.

Property and Industrial Development

Some former mine sites, particularly those near regional growth corridors, are also catching the eye of property and industrial developers. These investors are interested in transforming land into logistics hubs, industrial estates, or even new residential precincts.

To unlock their interest, sites must be backed by a regional development vision, clear zoning pathways, and infrastructure planning that aligns with population and economic growth strategies.

Tourism, Conservation, and Cultural Enterprises

Rehabilitated mine sites with natural beauty, ecological value, or cultural significance have the potential to support eco-tourism ventures, nature reserves, or Indigenous-led cultural experiences.

Attracting investment in this space depends heavily on early engagement with Traditional Owners, clarity around land tenure, and recognition of the non-financial — but high-impact — value these projects can deliver.

Impact Investors and Global ESG Capital

Internationally, the appetite for investments that align with climate action, social equity, and environmental restoration is growing fast. These investors — from impact funds to philanthropic capital — are looking for projects with measurable outcomes and long-term partnerships.

They are particularly drawn to post-mining projects that demonstrate a clear social licence, strong community engagement, and alignment with just transition principles.

What It Takes to Unlock Investment

To attract these investors, NSW must do more than promote land. It must prepare it.

That means:

• Developing investment-ready precincts through coordinated planning and governance
• Providing clear regulatory pathways and flexible land use frameworks
• Offering transparent site data, infrastructure assessments, and risk mapping
• Backing strategic sites with government co-investment or incentive frameworks
• Fostering public-private-community partnerships with a shared vision for long-term benefit

Investment will not come because land is available — it will come because opportunity has been clearly defined, risk has been managed, and outcomes are aligned.

In post-mining regions, that alignment is now possible. What’s needed next is intent — and follow-through.

What Happens If We Don’t?

If NSW fails to act, it risks locking in decline:

• Stranded infrastructure decommissioned rather than reused.
• Rising unemployment and social dislocation in mining communities.
• Lost opportunity for biodiversity, reconciliation, and regional reinvention.
• Missed investment as policy uncertainty drives capital elsewhere.
• A leadership moment that could define NSW lost to hesitation.

“If we don’t seize this moment, we will have failed to turn the end of mining into the beginning of something better.” — Submission to the inquiry

Making It Happen: The Role of Each Stakeholder

The path to transformation will only succeed if everyone plays their part. Here’s what each stakeholder needs to do:

• Local Councils Lead place-based planning, reform local zoning, engage communities early, and unlock priority sites.
• Mining Companies Adapt final land uses, share site data, repurpose infrastructure, and co-invest in regional transition.
• NSW Government Deliver legislative reform, fund Place Delivery Groups, appoint a transition authority, and coordinate agency action.
• Industry Associations Advocate for reform, develop standards, bridge industry and government, and share lessons.
• Community and Environmental Groups Push for transparency, co-design land uses, lead local projects, and uphold accountability.
• Research Institutions Provide evidence, support innovation pilots, guide workforce programs, and track impact.
• Clean Tech Innovators Deploy solutions for energy and resource reuse, lead project development, and demonstrate viability.
• Workforce and Unions Protect jobs, shape reskilling efforts, and help communities navigate transition fairly.
• Investors and Developers Unlock private capital for post-mining precincts, partner with councils, and activate long-term value.

The Time to Act is Now

This isn’t just about mine closure. It’s about reframing regional NSW for the next century.

The reforms in Report No. 53 won’t be easy — but they are achievable. With strong leadership, aligned policy, and genuine community partnership, we can make post-mining land a platform for clean energy, regional development, and ecological renewal.

Let’s ensure that the legacy of coal is not just what we extracted — but what we built afterward.

Executive Summary

• Australia’s mandatory climate reporting from 2025 requires climate scenario analysis across short, medium, and long terms.
• Mine closure and post-closure phases are materially affected by climate risks and must be included in corporate disclosures.
• Climate scenario modelling can strengthen closure plans by anticipating environmental changes, improving cost estimates, and building regulatory and community trust.
• GIS technology and climate data allow mining companies to spatially model the impacts of climate scenarios on closure outcomes.
• Risks extend beyond the mine lease boundary, impacting regional land uses, ecosystems, and transition economies.
• Mining companies that embed climate resilience into closure planning will lead on ESG performance, risk management, and investor confidence.

Introduction
Mine closure is often thought of as the final act of mining — a technical and regulatory exercise to rehabilitate disturbed land. But Australia’s incoming mandatory climate-related financial disclosure framework, starting from January 2025, changes that paradigm completely.

Under the new regime, mining companies must analyse and disclose how climate change impacts their entire business model — not just their operating mines, but also their closure plans, post-closure obligations, and even legacy sites. Climate scenario modelling — a key feature of the reporting standards — offers an essential tool to stress-test closure strategies and embed climate resilience into the heart of mine lifecycle planning.

In this article, we explore why closure planning cannot be left out of mandatory climate reporting and how scenario analysis can create stronger, smarter, and more trusted mine closure outcomes.

Mandatory Climate Reporting: A New Reality
Australia’s Sustainability Reporting Standards, particularly AASB S2, require entities to disclose:

• Climate-related risks and opportunities,
• Their financial impacts over the short, medium, and long term,
• The outcomes of climate scenario analysis,
• And the governance and risk management structures that support climate resilience.

Importantly, these obligations apply to the entire business, not just current operations. Closure and post-closure liabilities, environmental risks, and social transition risks are all firmly in scope.

Why Closure Planning Must Evolve

Closure is a Material Risk

Mine closure carries long-tail risks:

• Environmental liabilities (erosion, acid mine drainage, vegetation failure),
• Financial liabilities (rehabilitation funds, maintenance of water treatment facilities),
• Social risks (community transition failure, reputational damage).
  These risks have the potential to be exacerbated by climate change — and therefore must be identified, quantified, and disclosed under the new standards.

Scenario Modelling Strengthens Closure Planning

Climate scenario analysis enhances closure planning in multiple ways:

• Environmental Resilience: Stress-tests rehabilitation success under hotter, drier, or more extreme rainfall conditions.
• Financial Resilience: Identifies potential cost escalations, informing more accurate financial provisioning and assurance.
• Strategic Resilience: Tests the viability of post-mining land uses under changing climates, improving transition planning.
• Governance Resilience: Integrates closure risks into board-level risk management and sustainability strategies.

Closure plans built without climate scenario modelling risk being outdated the moment they are completed.

Climate Risks Extend Beyond the Mine Lease

Closure-phase climate risks do not respect lease boundaries. They affect:

• Neighbouring ecosystems and landholders (e.g., water flows, dust, fire risk),
• Regional economies (e.g., transition to agriculture or carbon farming),
• Cumulative impacts across landscapes, particularly in mining-intensive regions.

In this context, climate-resilient closure is not just an operational task — it’s an essential part of corporate ESG strategy and regional sustainability leadership.

The Critical Role of GIS and Climate Data in Scenario Modelling

A powerful enabler of effective climate scenario analysis is the integration of Geographic Information Systems (GIS) and high-resolution climate data. This spatial approach adds a critical dimension to mine closure planning:

• Mapping Vulnerabilities: GIS allows companies to visualize how temperature increases, rainfall shifts, flood risks, and fire hazards might spatially impact rehabilitation areas, tailings storage facilities, and final landforms.
• Predicting Erosion and Stability Risks: By overlaying climate models onto topography and soil data, companies can predict future erosion patterns and slope stability under different climate scenarios.
• Designing Adaptive Landforms: Spatial models can inform the design of landforms and drainage systems that are more resilient to altered hydrology and extreme weather events.
• Optimizing Post-Mining Land Use: GIS analysis helps evaluate future land suitability for agriculture, conservation, or carbon offsetting based on changing climate conditions.
• Communicating with Stakeholders: Spatial climate models offer intuitive visualizations for engaging regulators, communities, and investors in understanding climate-related closure risks and mitigation strategies.

By harnessing GIS and climate data together, mining companies move from conceptual to evidence-based, spatially explicit closure strategies — strengthening compliance, resilience, and stakeholder confidence.

Practical Steps to Embed Climate Scenario Modelling into Closure

Mining companies should:

1. Select relevant climate scenarios (aligned with IPCC pathways) for each region and asset.
2. Integrate climate datasets with GIS layers of environmental and rehabilitation features.
3. Quantify climate impacts spatially on landforms, hydrology, vegetation, and infrastructure.
4. Model financial implications for closure and post-closure liabilities under different scenarios.
5. Document and disclose assumptions, methodologies, and risk mitigation strategies transparently.
6. Continuously update closure strategies as climate projections evolve.

Early adopters will be better positioned to demonstrate leadership to regulators, investors, and communities.

The Strategic Advantage

Companies that integrate climate scenario analysis and spatial modelling into closure planning:

• Build more resilient and cost-effective rehabilitation solutions,
• Enhance investor confidence through transparent risk management,
• Strengthen regulatory trust by anticipating future challenges,
• Maintain social license by demonstrating responsible, forward-looking closure outcomes.

Mine closure is no longer simply an environmental compliance obligation — it’s a strategic ESG and financial priority.

Take homes……

As mandatory climate reporting becomes reality, the mining sector must broaden its view: Mine closure and post-closure periods are at the very center of climate risk exposure — and opportunity.

Climate scenario modelling, combined with GIS-based spatial analysis, offers the tools to future-proof closure plans, protect financial resources, and strengthen corporate sustainability narratives.

The companies that act now will not only meet compliance — they will lead the transition to a more resilient, trusted, and sustainable mining sector.

As mine closure evolves into a more structured and regulated phase of the mining lifecycle, independent peer reviews have emerged as an essential tool for stress-testing closure plans. Done well, they can identify significant risks, uncover strategic opportunities, and ultimately lead to better environmental, financial, and social outcomes.

Drawing on IEMA – Integrating Sustainability, Business & Community experience developing and reviewing closure plans across coal, hard rock, and industrial mineral sites, this article explores key technical areas where peer reviews can add tangible value.

Peer Review: Beyond Compliance

Peer reviews are sometimes perceived as a final gate in the regulatory process — a checkbox before submission. But at their best, they are a collaborative interrogation of closure logic, aimed at strengthening assumptions, validating risk treatments, and unlocking better outcomes.

Common peer review triggers include:

• Independent assurance for regulators or boards
• Pre-submission review of closure plans or cost models
• Change in closure scope or post-mining land use vision
• Periodic review under internal assurance frameworks

The following technical insights highlight where reviews often yield the greatest benefits.

Cost Models: Where Strategic Value Can Be Found

Closure cost estimates are a central component of a mine’s liability profile, yet they are often based on layered conservatism, outdated assumptions, or generic rates. Through independent review, we routinely uncover opportunities to refine these models.

Common Costing Pitfalls Identified in Technical Review

1. Underestimated Monitoring Durations
2. Redundant or Duplicated Rehabilitation Phases
3. Missed Opportunities for Early Works
4. Inaccurate Earthworks and Haulage Assumptions
5. Oversimplified Revegetation Models
6. Incomplete Demolition and Decommissioning Scope
7. Regulatory Delay Risk Underestimated
8. Holding Costs Post-Closure
9. Tailings and Water Management Facilities
10. Contractor Management and Mobilisation

By reviewing these assumptions in detail, we help clients not only meet regulatory expectations but improve internal decision-making and funding efficiency.

Hydrology, Voids, and Uncertainty

Final voids and water infrastructure often carry the greatest long-term environmental risk. Reviews frequently challenge:

• The robustness of water balance models
• Final void fill timelines and geochemical behavior
• Surface infrastructure integration with rehabilitated catchments

These issues often benefit from multidisciplinary scrutiny by hydrologists, hydro geochemists, and geotechnical engineers to ensure performance-based closure.

Tailings, Waste, and Landform Transitions

Tailings dams and waste rock facilities require significant scrutiny. We often find:

• Closure timeframes that underestimate tailings drying or cover material placement
• Incomplete costing of seepage barriers or revegetation performance
• Untapped opportunities to remove or rehandling waste early in the closure cycle (or better during operations)

Technical reviews in this space can drastically change the long-term liability trajectory and improve the safety profile of the final landform.

Post-Mining Land Use and Stakeholder Alignment

Closure success is increasingly judged by its social and legacy outcomes. Independent reviews often identify:

• Failure to assess high value beneficial landuse options
• Weak connections between closure objectives and stakeholder aspirations
• Underdeveloped integration of community land use preferences or cultural values
• Gaps in documentation to support future access, signage, or co-use arrangements

Reviews supported by social performance and cultural heritage experts can transform these elements from afterthoughts into drivers of closure success.

Delayed Relinquishment and Residual Liability

Even technically successful sites can face years of residual holding costs due to incomplete regulatory closure. Peer reviews help:

• Misalignment between approved completion criteria and the monitoring that delays the sites ability to demonstrate that the rehabilitation is on the trajectory for success.
• Failing to capture and record evidence that demonstrates effective processes in all phases (ITPs)
• Identify missing documentation or evidence for sign-off
• Recommend early actions that target lingering uncertainty and potential residual risk aspects
• Cost the full spectrum of post-closure obligations — not just physical works, but legal, social, and governance processes

Why IEMA’s Peer Reviews Add Value

At IEMA – Integrating Sustainability, Business & Community we approach peer reviews with the same depth of care we apply to closure planning itself. What makes our approach unique is our ability to bring together diverse technical specialists — from hydrologists and geochemists to social scientists and cultural heritage professionals — into a coherent, structured review process.

Because we’ve developed closure plans ourselves, we know where things often get overlooked — and how to build defensible, cost-efficient strategies that regulators, communities, and boards can trust.

Final Thought

Independent Peer Review is more than due diligence — it’s an opportunity to elevate closure planning, challenge embedded assumptions, and ensure mine closure delivers value well beyond compliance. As expectations grow for transparency, ESG outcomes, and relinquishment readiness, technically robust reviews will play a critical role in delivering success.

If you’re in the middle of a closure review, preparing a cost model, or developing a relinquishment roadmap — we welcome the chance to connect and contribute to better closure outcomes across the sector.

In recent years, ESG (Environmental, Social and Governance) has become deeply embedded in the way businesses report, invest, and strategise. It was driven by climate urgency, global agreements like the Paris Accord, and a rapidly growing set of frameworks like the TCFD, GRI, ISSB, and UN SDGs.

But things are changing.

As the political landscape shifts back toward the centre-right in many parts of the world, the ESG conversation is evolving. Compliance and alignment with global standards are no longer the only game in town. ESG is starting to look more local, more practical, and more integrated with core business value.

This doesn’t mean ESG is going away — far from it. But it does mean the way businesses approach ESG must change. It’s no longer just about ticking boxes. It’s about performance, people, and purpose.

ESG in a Centre-Right World: From Guidelines to Ground Truth

Centre-right governments tend to resist regulation and favour market-led solutions. That’s changing the ESG dynamic. Boards are asking:

• What’s material to our business?
• What are the commercial benefits?
• How do we show outcomes, not just intentions?
• The result? A leaner, sharper ESG — focused on what matters most.

Australia’s Reporting Regime: Momentum You Can’t Ignore

In Australia, the mandatory climate-related financial disclosure regime kicks off in 2025 for Tier 1 reporters. Even if the political winds shift and mandatory requirements are softened or delayed, the direction is set.

Investors, banks, clients, and insurers are already requiring ESG transparency. Inertia will keep the market moving — with or without regulation.

For businesses not yet captured by the rules, now is the time to act. By moving early, you can:

• Build internal ESG capability
• Establish data systems and governance
• Position yourself ahead of slower competitors

In ESG, being ready is a competitive edge.

ESG Is Now a Talent Strategy

One of the strongest cases for ESG in a centre-right environment? Your people.

Younger generations — and increasingly, employees of all ages — want to work for companies that reflect their values. ESG is about creating workplaces that are:

• Purpose-led
• Inclusive
• Sustainable
• Transparent

Companies that live their ESG values attract stronger talent, retain their best people, and build better cultures.

In a tight labour market, that’s not idealism — it’s smart workforce strategy.

ESG and Access to Capital

Even without mandates, ESG is already baked into lending, insurance, and investment decisions. Poor ESG performance means:

• Higher premiums
• Tighter lending conditions
• Lost investor interest
• Exclusion from tenders and supply chains

Banks and super funds aren’t waiting for regulation. They’re pricing ESG risk now. If you’re not aligned, you’re paying for it — one way or another.

ESG as a Risk Management Tool

Good ESG is good business risk management. It helps companies:

• Prepare for climate and energy shocks
• Address modern slavery and supply chain ethics
• Manage reputational risk
• Maintain community trust and social licence

When done well, ESG is not the risk — it’s how you manage it.

Local, Not Just Global

ESG used to be about aligning with frameworks created in New York, Brussels, or Geneva. That still matters — but increasingly, ESG is judged by what happens on the ground.

In Australia, this includes:

• Creating regional jobs
• Partnering with Indigenous communities
• Rehabilitating land and water
• Building community trust

The most credible ESG stories are local and lived, not just reported.

Digital ESG: A Smarter Way Forward

New tools are changing the game. From AI to ESG data platforms, businesses are moving beyond spreadsheets and PDFs to real-time reporting and performance dashboards.

Digitising ESG:

• Saves time and cost
• Creates clearer insights
• Makes reporting scalable and repeatable
• Supports integration across finance, HR, ops, and risk

Technology makes ESG smarter, faster, and easier to embed.

The Cost of Waiting

Tempted to wait? Don’t.

Doing nothing now could mean:

• Lost tenders
• Scrambling to meet reporting deadlines
• Failing to attract top talent
• Falling behind in your industry

Inaction is not neutral. It’s risky.

ESG: From Compliance to Culture

ESG isn’t disappearing. It’s evolving.

The smartest organisations are embedding ESG not in their compliance teams — but in their strategy, operations, culture, and communications. ESG is no longer just about satisfying regulators. It’s about building resilient businesses that attract talent, reduce risk, access capital, and earn community trust.

In short, ESG is growing up. And those who act early, act smart, and act locally will be the ones who lead.

As industries shift towards more sustainable operations, mine closure planning is undergoing a significant transformation. Traditionally, mine closures have followed a linear model, where resources are extracted, used, and then discarded. However, by embedding circular economy principles, closures can extend beyond mere compliance to deliver long-term environmental and economic benefits. A key tool enabling this transition is circular flow analysis, which employs various modelling and assessment techniques to identify opportunities for circularity within mine closure strategies.

 

From Linear to Circular: The Power of Circular Flow Analysis

Circular flow analysis is a suite of quantitative and qualitative methods that examine the movement of materials, energy, waste, and economic value within a system. These approaches help mine closure planners understand how resources circulate within the system, identifying opportunities to retain value, repurpose materials, and close resource loops. This data-driven methodology enables targeted interventions that minimise waste, maximise reuse, and reduce environmental impact.

 

Key Applications of Circular Flow Analysis in Mine Closure

1. Material Flow Analysis (MFA) for Resource Recovery
2. Water Flow Modelling for Sustainable Management
3. Energy Flow Modelling for Renewable Integration
4. Biodiversity and Ecosystem Flow Analysis

 

Technical Methods for Circular Flow Analysis in Mine Closure

To implement circular economy strategies effectively, several technical methods are employed to analyse and optimise resource flows:

1. Material Flow Analysis (MFA)
   • A systematic approach to quantifying material movement within a system.
   • Helps identify resource recovery opportunities and potential for reuse in mine closure projects.
2. Life Cycle Assessment (LCA)
   • Evaluates the environmental impact of a mine closure strategy across its entire life cycle, from extraction to rehabilitation.
   • Aims to optimise sustainability outcomes by reducing waste and emissions.
3. Substance Flow Analysis (SFA)
   • Tracks specific chemical substances or pollutants within a mining system.
   • Useful for managing contaminants in tailings, mine water treatment, and soil remediation.
4. Systems Dynamics Modelling (SDM)
   • Simulates complex interactions between material, energy, and economic flows.
   • Helps predict long-term sustainability outcomes and informs decision-making in circular mine closure planning.
5. Industrial Ecology and Symbiosis Modelling
   • Focuses on creating closed-loop systems where waste from one industry serves as input for another.
   • Applied to repurpose mining waste in construction, manufacturing, or agriculture.
6. Circularity Assessment Models (CAMs)
   • Evaluates the circularity performance of a mine closure strategy by mapping resource flows and intervention points.
   • Benchmarks sustainability performance against global circular economy standards.

 

Key Strategies for a Circular Economy in Mine Closure

1. Repurposing Mining Infrastructure and Materials
   • Reusing mine buildings and equipment for alternative industries such as vertical gardens, manufacturing, research, tourism, or intensive agriculture or aquaculture.
   • Deconstructing and salvaging materials such as steel, concrete, and machinery for reuse in new construction projects or other existing projects.
   • Considering former tailings storage facilities as sources of secondary minerals through advanced re-processing technologies.
2. Maximising Beneficial Land Use
   • Converting decommissioned sites into renewable energy hubs, such as solar or wind farms.
   • Creating new agricultural or forestry projects, turning rehabilitated land into productive farming zones, considering manufacturing, vertical gardens, etc.
3. Circular Water Management and Ecosystem Rehabilitation
   • Designing closed-loop water treatment systems to ensure mine water is treated and reused efficiently for other long term beneficial uses.
   • Applying bioengineering techniques to restore soil and water quality in degraded mine landscapes.
   • Creating artificial wetlands and natural filtration systems to support local biodiversity while improving water management.

The Future of Circular Mine Closure: A Data-Driven Approach

By integrating circular flow analysis into mine closure planning, industry stakeholders can move beyond linear decommissioning to circular, regenerative strategies. This approach is important because it:

• Optimises resource use by tracking materials, water, and energy.
• Reduces waste and emissions through intelligent planning.
• Creates long-term value by repurposing infrastructure and resources.

As expectations evolve, circular flow analysis and circular economy principles will be vital in ensuring that former mine sites become long-term assets rather than environmental liabilities.

Mining communities face a critical challenge: how to reinvent themselves beyond closure of the mine. The current approach to mine closures in NSW have the potential to leave the regions struggling as it is dominated by biodiversity and traditional grazing outcomes which are a remnant of the current Planning and Approval process. However, a new solution is emerging—Circular Economy (CE) Hubs—which integrate waste recovery, renewable energy, sustainable food production, and advanced manufacturing into a self-sustaining industrial ecosystems, particularly in areas that are currently industrial areas with significant infrastructure like high voltage power, water and sheds.

Around the world, former industrial sites are being repurposed into thriving economic hubs that drive investment, create jobs, and position mining regions as leaders in sustainable industries. This article explores case studies of successful CE hubs and examines how an approach that looks outside the current thinking to new things like integrating vertical farming, intensive agriculture, and industrial symbiosis which has the potential to create a high-value, resilient economy post-mining.

 

Case Studies: Circular Economy Hubs in Action

1. Kalundborg Symbiosis, Denmark – Industrial Resource Sharing

The People-Centric Approach to Carbon Management

It’s no secret that sustainability initiatives often live or die by the level of employee buy-in. Organisations that succeed in engaging their workforce find that the benefits extend far beyond compliance or public relations. For SMEs, where resources are often stretched, harnessing the passion and creativity of employees can be a game-changer.

“People want to see the difference they’re making,” says Andrew Hutton, Managing Director of IEMA. “When employees are equipped with tools to track and reduce emissions, it fosters a sense of ownership and collective responsibility. Sustainability becomes personal, not just a corporate goal.”

Engaging employees in emissions reduction offers several advantages:

• Awareness and Accountability: Involving staff in sustainability initiatives raises awareness of the environmental impacts of their roles, encouraging accountability and innovation in daily operations. For SMEs, this can unlock low-cost or no-cost opportunities to reduce emissions through behavioural changes.
• Empowered Action: Providing employees with access to tools like real-time emissions tracking allows them to see the immediate effects of their actions, making sustainability tangible rather than abstract.
• A Collaborative Culture: Carbon management often requires input from multiple departments. In smaller businesses, this fosters teamwork across often tightly knit teams, creating stronger bonds.
• Job Satisfaction and Retention: A workplace that values sustainability is often more appealing to employees, especially younger generations, who see environmental action as a key organisational responsibility. This is particularly important for SMEs competing for top talent against larger organisations.

More importantly, it signals a shift in how organisations of all sizes approach their role in securing intergenerational equity. This is not just about meeting regulations or ticking ESG boxes. It’s about embedding sustainability into the very fabric of how a business operates, involving employees, clients, and stakeholders in a shared journey towards a fairer, greener future.

As Andrew Hutton explains: “Sustainability isn’t something you achieve alone. It’s about collaboration, innovation, and putting people at the heart of the process. For small and medium-sized businesses, the opportunity to lead in this space is immense. By partnering with Sumday, we’re helping businesses of all sizes empower their teams and create lasting change.”

Across NSW, coal mines that once powered entire communities are beginning to look to the future. From Gloucester, the Hunter Valley, Lake Macquarie, and to Wollongong in New South Wales, mining towns are grappling with the same urgent question: What comes next? Its not going to all hit now, but as mines naturally arrive at the end of their economical life along with a global transition away from fossil fuels , the focus is shifting to what these post-mining landscapes can offer—and how they can continue to provide jobs and opportunities for local our local communities.

Renewable energy projects and environmental rehabilitation are an important part of the solution mix, but they cannot provide the whole answer. For mining communities that have relied on high-paying, skilled jobs, the solution lies in combining these initiatives with bold and pragmatic land-use strategies that prioritise economic continuity, job creation, and long-term prosperity.

Repurposing Mining Land for Employment

Mining has always required a skilled workforce—engineers, heavy machinery operators, logistics managers—trained to work in demanding environments. These skills don’t have to disappear when the mines do. Across the globe, former mining regions are reimagining their futures with a focus on industries that provide meaningful employment.

One of the greatest untapped opportunities for transitioning mining sites lies in leveraging the existing infrastructure. Most mine sites are equipped with extensive facilities such as large industrial sheds, rail connections, water management systems, high-energy power supplies, fuel storage, and water infrastructure. These assets represent significant capital investments that, if preserved, could drastically reduce the costs of repurposing the land for alternative uses. However, current mine closure plans often focus on decommissioning and demolishing this infrastructure, eliminating a vital resource that could be repurposed to support new industries and job creation.

• Industrial and Manufacturing Hubs: In Germany’s Ruhr Valley, a region once defined by coal mines is now thriving as a center for industrial technology and logistics. Similarly, in Canada’s Sudbury region, mining expertise has been leveraged to create a robust mining services and equipment manufacturing industry, sustaining thousands of jobs.
• Housing Development: Closer to home, former mining areas near Lake Macquarie, Wollongong, and Newcastle present unique opportunities to address Australia’s growing housing crisis. Its not new – Belmont, Redhead, Dudley, Catherine Hill Bay and Wyee are all residential areas that were once mining land. With population growth driving demand for new homes, other sites in NSW could see disused mining land transformed into residential developments, creating construction jobs while delivering much-needed housing.

Housing as a Catalyst for Jobs

The transformation of post-mining land into housing developments offers more than just homes—it can revitalise entire regions. Residential projects require significant investment in infrastructure, such as roads, schools, and utilities, creating thousands of jobs in the process. Beyond construction, the influx of new residents supports local businesses, healthcare services, and schools, laying the foundation for sustainable economic growth.

Reimagining the Post-Mining Landscape

But there’s more…….Beyond housing, there are other industries that can breathe new life into these regions:

• Intensive Agriculture: Rehabilitated mining land offers a unique opportunity for intensive agriculture projects such as aquaculture, vertical farming, feedlots, and poultry farms. These industries require less arable land than traditional farming while providing steady employment opportunities. For instance, aquaculture can utilise water-filled pits from mining operations, while vertical farming offers year-round crop production in repurposed industrial spaces.
• Eco-Industrial Parks: Areas like the Latrobe Valley in Victoria are exploring eco-industrial parks that combine industrial development with environmental restoration, generating jobs in construction, operations, and maintenance.
• Mining Services and Technology: Even after mining stops, the expertise of mining regions can be redirected into mining equipment manufacturing and innovation. Sudbury, Canada, has set a benchmark in this area, showing how a mining legacy can support cutting-edge industries.

Challenges and Opportunities

The road ahead requires a balanced and thoughtful approach. Renewable energy projects, while a critical part of the solution, may not always be the best fit for every mining site. These projects are often well-suited to former mine sites located further away from population centres, where the large tracts of land and existing infrastructure can support wind, solar, and battery storage facilities with minimal disruption. They play a vital role in Australia’s transition to a cleaner energy future and can provide jobs and economic value in more remote areas.

However, for former mining sites located closer to major urban centres, alternative land uses may deliver greater benefits to communities. Housing developments, intensive agriculture, industrial hubs, and eco-industrial parks have the potential to create more local jobs, drive economic growth, and meet pressing regional demands such as housing shortages and food production. These alternatives also allow for the integration of these sites into the broader urban fabric, ensuring that communities continue to thrive.

Crucially, the significant infrastructure already present on mining sites offers a head start for these projects. Preserving and repurposing facilities such as sheds, water and power systems, and rail connections can dramatically reduce the capital investment required, making these sites more attractive for redevelopment. Mining communities closer to urban areas have the opportunity to reimagine their futures in ways that align with regional needs and priorities, while remote sites can contribute to broader national goals such as renewable energy production. This tailored approach ensures that every site reaches its full potential in creating jobs and supporting local economies.

Governments, mining companies, and local stakeholders must collaborate to design and implement these strategies. Strong regulations, incentives for innovation, and investment in retraining programs will be key to ensuring communities are not only part of the solution but also benefit from the transition.

A New Chapter for Mining Towns

The closure of a mine doesn’t have to signal the end for a community. With strategic planning and a focus on job creation, post-mining landscapes can become the foundation of thriving, diverse economies. For regions like Wollongong, Newcastle, Lake Macquarie, the Hunter Valley, and Gloucester, the opportunity is clear: transform disused mining land into housing, intensive agricultural hubs, and industrial centers that create jobs and ensure long-term prosperity.

The communities that helped power Australia’s growth deserve a future filled with opportunity. By preserving existing infrastructure and investing in employment-driven land-use strategies, we can ensure they have one.
