Rio Tinto delivered a mixed but resilient performance in the full-year 2025. While weaker iron ore prices weighed on profits, strong copper growth and disciplined cost control helped the mining giant keep earnings stable and maintain its dividend.
The world’s largest iron ore producer reported underlying earnings of $10.87 billion for the year ended December 31, unchanged from 2024. However, net profit fell 14% to $9.97 billion, compared to $11.55 billion a year earlier.
Despite the profit decline, Rio Tinto kept its shareholder payout steady. It declared an ordinary dividend of $6.5 billion, maintaining a 60% payout ratio. This marked the tenth straight year the company paid at the top end of its target range.
Iron Ore Softens, Copper and Aluminium Step Up
Lower iron ore prices hurt earnings. As the backbone of Rio Tinto’s business, iron ore remains critical. However, copper and aluminium delivered strong support.
Copper production rose 11% year over year. The key driver was the ramp-up of the Oyu Tolgoi underground project in Mongolia, where output surged 61%. This project is now complete and will play a major role in future copper growth.
Aluminium also performed well across the value chain. The company achieved record annual bauxite production of 62.4 million tonnes. As a result of higher volumes and better productivity, Rio Tinto reduced operating unit costs by 5% in real terms during 2025.
Operational cash flow strengthened. Net cash from operating activities rose 8% to $16.8 billion. Meanwhile, underlying EBITDA climbed 9% to $25.4 billion. These gains reflected operational discipline and tighter cost management.
Looking ahead, the company aims to deliver a 4% compound annual unit cost improvement through 2030. It also expects productivity initiatives to generate $650 million in annual benefits by early 2026.
Big Projects Drive Future Growth
Rio Tinto made significant progress across its global project pipeline in 2025. The major milestones are explained below:
Simandou Iron Ore Project
The Simandou project in Guinea reached a major milestone. The company shipped its first high-grade iron ore in December. This project is expected to strengthen long-term supply and improve product quality.
Pilbara Replacement Mines
In Western Australia’s Pilbara region, the Western Range replacement mine opened on time and on budget. Additionally, construction began at three more brownfield iron ore mines. Four of the five major replacement projects are now either ramping up or under construction.
Copper Expansion
The Oyu Tolgoi underground development is complete. Rio Tinto also achieved first production of Nuton copper at the Johnson Camp mine. The company remains on track to deliver 3% compound annual growth in copper-equivalent production through 2030.
Lithium Growth
In March, Rio Tinto closed its acquisition of Arcadium ahead of schedule. The focus now shifts to advancing lithium projects in Argentina and Canada. The company targets 200,000 tonnes per year of lithium carbonate equivalent capacity by 2028.
Together, these projects strengthen Rio Tinto’s position in future-facing commodities like copper and lithium, which are essential for electrification and the energy transition.
Strong Balance Sheet and Capital Discipline
Despite profits falling, Rio Tinto’s financial position remains solid. Its strong cash flow supports consistent dividends and future investment. The company plans to unlock between $5 billion and $10 billion from its asset base. It is currently reviewing options for its borates and titanium dioxide (TiO₂) businesses and considering infrastructure monetization.
Management also streamlined operations. It reduced its structure from four product groups to three core divisions, i.e., iron ore, aluminium & lithium, and copper
Additionally, the company reduced contractor numbers and discretionary spending. It also placed the Jadar project into care and maintenance and stopped non-core studies. These steps sharpened its focus on value-generating assets.
Climate Action: Progress with Challenges
Sustainability remains an important part of Rio Tinto’s long-term strategy. The company spent $612 million on decarbonization initiatives in 2025, up from $589 million in 2024
In 2025:
- Gross Scope 1 and 2 emissions were 31.5 million tonnes of CO₂ equivalent, down 14% from the 2018 baseline of 36.7 million tonnes.
- Scope 3 emissions, which include customer use of products, reached 575.7 million tonnes of CO₂ equivalent. These emissions represent the largest share of its climate footprint. After applying high-quality carbon offsets, net emissions were 17% below baseline.
However, progress slowed compared to prior years. Emissions fell by just 0.2 million tonnes from 2024 levels. Increased production in iron ore and copper partly offset reductions.
Renewable Energy Contracts and Carbon Credits
The mining giant relies on renewable energy contracts and renewable diesel use, especially at its Kennecott site. It also retired about 1.01 million Australian Carbon Credit Units (ACCUs) to meet regulatory requirements.
Still, the path to its 2030 target of a 50% reduction in Scope 1 and 2 emissions depends on third-party renewable projects and successful commercial agreements. These factors remain outside the company’s direct control.
Around 7% of its electricity came from renewable sources, slightly lower than 78% in 2024 due to accounting adjustments in reported figures.
Environmental and Water Management
Air quality indicators such as NOx, SOx, and fluoride levels remained relatively stable over five years. However, PM10 levels increased slightly over the past three years. To reduce emissions at the source, Rio Tinto continues to upgrade equipment with best-available technologies. It also expands air monitoring networks around its operations.
Water management improved in 2025. Total operational water withdrawals declined to 1,147 gigalitres, down from 1,250 gigalitres in 2024. Freshwater withdrawals also fell slightly to 386 gigalitres.
Water recycling increased to 374 gigalitres, showing better reuse practices. Meanwhile, total water discharges dropped to 626 gigalitres.
The company advanced several community-focused water initiatives, including implementing a new water strategy at QIT Madagascar Minerals. It also increased transparency by publishing detailed water performance data.
The Bigger Picture
Overall, Rio Tinto delivered steady underlying earnings in a challenging pricing environment. Iron ore weakness pressured profits, yet copper and aluminium provided strong support.
At the same time, disciplined capital allocation, operational efficiency, and large-scale project execution strengthened its long-term outlook.
Looking forward, growth will rely heavily on copper and lithium. These metals sit at the heart of global electrification and decarbonization trends. If Rio Tinto delivers on its cost improvements and project milestones, margins and cash flow could improve further.
However, climate targets remain ambitious. Achieving deeper emissions cuts will require faster renewable energy deployment and broader collaboration across its value chain.
In short, 2025 showed resilience rather than rapid growth. Rio Tinto balanced shareholder returns, project expansion, and sustainability progress. Now, its future depends on executing its copper-led strategy while navigating commodity cycles and climate commitments.

More and more small and medium-sized businesses are hearing the same question from their larger customers: What is your carbon footprint? That question now travels down entire supply chains, and it arrives next to tender requirements, certification criteria, and rising customer expectations.
The accounting differences that decide whether your nature investment shows up in inventory, in BVCM, or nowhere at all.
The question reaches a procurement team about three weeks before the next sustainability committee meeting. Someone has read about insetting. Someone else has just signed off on an offset purchase. The CSO wants to know if the two are interchangeable. The answer is no, and the GHG Protocol Land Sector and Removals Standard is the reason why.
This article walks through what each term means at audit-grade specificity, what the standards actually say about how each gets counted, and how to decide which tool fits which target. The insetting vs offsetting question is one of the most-searched in corporate climate strategy, and one of the most poorly answered. By the end of this piece, you should be able to brief a committee on the difference without notes.
The two definitions, in plain English
Offsetting means buying carbon credits generated outside your value chain and retiring them against your residual emissions. The reduction happens somewhere else, financed by you, and the credit is the receipt.
Insetting means investing in emission reductions or removals inside your own value chain, typically with suppliers, where the reduction is directly linked to the products and services you buy. The reduction happens inside the boundary of your Scope 3 inventory, and the accounting treatment is fundamentally different.
The shorthand from the University of Oxford’s Nature-based Insetting Initiative is useful: insetting is what you do with the supply chain you have; offsetting is what you do with the supply chain you do not have.
What the GHG Protocol Land Sector Standard actually says
The GHG Protocol Land Sector and Removals Standard, finalised in 2024 after a multi-year pilot, sets the rules for how land-based emission reductions and removals enter corporate inventories. The Standard distinguishes between inventory accounting (Scope 1, 2, and 3) and project or intervention accounting (a separate methodology for crediting).
For insetting, the practical implication is that supplier-level interventions, when properly measured and attributed, can reduce your Scope 3 category 1 (purchased goods and services) emissions in your inventory. The reduction is not a credit retired against the inventory; it is a lower inventory number, period.
For offsetting, the credit is retired separately. It can be reported as a contribution toward a net-zero claim under the SBTi Beyond Value Chain Mitigation framework or as part of a VCMI Carbon Integrity claim, but it does not lower the inventory number.
A practical consequence: if your Science Based Target requires a 50% absolute reduction in Scope 3 emissions by 2030, insetting moves you toward the target. Offsetting does not. This single point of difference reshapes the procurement decision.
When insetting counts toward Scope 3 (and when it does not)
Insetting counts toward Scope 3 only when several conditions are met:
- The intervention must occur with an entity in your value chain.
- The emissions reduction or removal must be measured against a defensible baseline.
- The reduction must be attributed to your share of that supplier’s output, not double-counted with other buyers.
- It must follow the inventory accounting rules in the GHG Protocol Land Sector Standard, not the project accounting rules used to generate credits.
The most common failure mode is double counting. If your supplier sells the same reduction as a credit on the voluntary market and also reports it to you as a Scope 3 reduction, the math breaks. The Standard requires you to address this risk, typically by purchasing and retiring the supplier-issued credit as part of your inventory or by contractual provisions that prevent the supplier from selling the reduction twice.
When insetting does not count toward Scope 3: when the intervention sits with a supplier you do not buy from, when the baseline is not defensible, when the attribution is unclear, or when the documentation does not survive audit. Those cases default to Beyond Value Chain Mitigation, which is still useful but operates on a different ledger.
The procurement and supplier engagement question
Insetting is harder than offsetting. That is the unfashionable truth most buyers eventually confront. Offsetting is a transaction; insetting is a relationship.
To run an insetting program, you need supplier mapping precise enough to know which farms or facilities sit at which Scope 3 boundary. You need an engagement model that gets suppliers to participate, which usually requires multi-year commitments and shared economics. You need an MRV architecture that measures the right things and produces audit-ready documentation. And you need a contractual structure that prevents double counting and protects both sides.
The trade-off you receive in return is significant. Reductions count against your inventory rather than your residual. Supplier relationships deepen, which protects sourcing continuity. Yield and quality improvements often follow regenerative interventions, which reduces your input cost over time. And the regulatory file, under CSRD, CSDDD, EUDR, and the SBTi FLAG Guidance, is materially stronger.
Choosing the right tool for the right target
A practical decision rule. If your target is a science-based Scope 3 reduction and you operate in a FLAG sector or source FLAG commodities, insetting is the structurally correct tool. If your target is a net-zero claim that includes neutralising hard-to-abate residual emissions outside your value chain, BVCM via high-integrity offsets is the structurally correct tool. Most companies with material Scope 3 exposure need both, in different proportions, sequenced over time.
The sequencing matters. Insetting takes longer to stand up but produces a permanent reduction in the inventory. Offsetting can be transacted faster but does not change the inventory and now sits under tighter claim restrictions. Treat them as complementary tools with different jobs, not as substitutes. The Accountability Framework Initiative and the IUCN Global Standard for Nature-based Solutions both provide useful guardrails for the insetting side, with biodiversity, human rights, and benefit-sharing requirements that go beyond carbon math.
If you are mapping a Scope 3 reduction roadmap and need to scope which interventions count toward your inventory versus which sit in Beyond Value Chain Mitigation, the carbon and sustainability experts at Carbon Credit Capital can help you structure a nature-based supply chain investment program that fits your FLAG exposure, your target architecture, and your audit horizon. Schedule a consultation.
Net zero is often described as a balancing act: cut what you can, account for the rest, and reach zero on the ledger. That framing is useful, but it leaves something out. It treats every tonne of carbon as interchangeable and every route to zero as equally sound, while the science tells a more specific story.
