Rio Tinto has completed its $6.7 billion acquisition of Arcadium Lithium in the U.S. The Royal Court of Jersey approved the deal on March 5, officially making Arcadium Lithium a part of Rio Tinto Lithium. This acquisition also brings the Rincon lithium project into Rio Tinto’s growing portfolio.

Rio Tinto’s Big Bet on Arcadium Lithium

  • With this acquisition, Rio Tinto aims to grow the capacity of its Tier 1 assets to over 200 thousand tonnes per year of lithium carbonate equivalent (LCE) by 2028.

Furthermore, it expects strong growth, higher EBITDA, and improved cash flow in the coming years. It will deploy advanced technologies and its strong global hold to boost its market presence in the lithium sector.

Explaining more, Rio Tinto Chief Executive Officer Jakob Stausholm said,

“Today we are delighted to welcome the employees of Arcadium to Rio Tinto. Together, we are accelerating our efforts to source, mine and produce minerals needed for the energy transition. By combining Rio Tinto’s scale, financial strength, operational and project development experience with Arcadium’s Tier 1 assets, technical and commercial capabilities, we are creating a world-class lithium business which sits alongside our leading iron ore, aluminium and copper operations. We believe we are well-positioned to deliver the materials needed for the energy transition while maintaining our focus on.”

As part of the agreement, Arcadium Lithium shareholders will receive $5.85 per share. To fund the purchase, Rio Tinto is using a bridge loan facility, which it plans to replace with long-term debt financing.

Following the acquisition, Arcadium Lithium’s shares and CHESS Depositary Receipts (CDIs) will be delisted from the New York Stock Exchange (NYSE) and the Australian Securities Exchange (ASX).

Lithium: The Power Player in Rio Tinto’s Future

The global shift toward electric vehicles (EVs) is fueling demand for lithium and other battery minerals. Rio Tinto expects lithium to become a crucial part of its portfolio, contributing more than 10% of its earnings (EBITDA) by 2033.

Other than Acradium Lithium, Rio Tinto invested $2.5 billion in the Rincon project in Argentina, which was approved last year in December 2024.

This expansion will increase the site’s annual capacity to 60,000 tonnes of battery-grade lithium carbonate. Additionally, it also includes a 3,000-tonne starter plant and a larger 57,000-tonne facility.

Construction is set to begin in mid-2025, after all permit approvals. After a three-year ramp-up, full production is expected by 2028. The Rincon mine will operate for 40 years while maintaining a low-cost position in the industry.

Navigating the Lithium Storm

The ongoing decline in lithium prices has sparked strong industry reactions. Some mining companies are delaying new projects, while others are cutting costs to stay profitable. Smaller lithium miners are feeling the most pressure. Without strong financial backing, many are struggling to survive. Some have even halted operations or are seeking mergers to stay afloat.

Notably, major producers like Albemarle and SQM plan to cut production, hoping to prevent further price drops and stabilize the market.

However, with these two massive lithium deals, Rio Tinto is consolidating its position in the global lithium market. Notably, the Acardium acquisition occurred amid an excess supply and significantly lower prices since their peak in 2022.

Despite battery advancements, lithium remains crucial, especially in China and Europe, where EV adoption is rising. Long-duration storage may boost demand, but alternative technologies could compete.

Rio Tinto’s lithium expansion plans support its sustainable mining strategy. Let’s discover how the mining giant is mitigating mining emissions.

Rio Tinto’s Net Zero Goals 

Rio Tinto has set ambitious targets to cut Scope 1 and 2 emissions by 50% by 2030 (compared to 2018 levels) and to achieve net-zero emissions by 2050. Its latest sustainability report revealed:

  • 2024 gross Scope 1 and 2 emissions: 30.7 Mt CO2e
  • 2024 emissions reduction: 3.2 million tonnes of CO2e through renewable energy contracts
  • Projected additional reductions by 2030: 3.6 million tonnes per year

To reach these goals, Rio Tinto has signed major renewable power purchase agreements and invested in solar and wind energy projects.

Additionally, the company is committing $143 million in Western Australia to develop BioIron™, an innovative ironmaking process that could slash CO2 emissions by up to 95% compared to traditional blast furnace methods.

Roadmap to a Greener Future

Rio Tinto’s comprehensive strategy to achieve its 2030 emissions target includes transitioning to renewable electricity and reducing process heat emissions at its alumina refineries. A key priority is cutting emissions at its Pacific Aluminium operations, particularly at the Boyne and Tomago smelters.

The company is also advancing other sustainability initiatives:

  • Richards Bay Minerals: Expanding renewable energy contracts
  • Queensland Alumina Limited (QAL): Improving alumina processing efficiency

Expanding the Use of Carbon Credits

To meet its 2030 net emissions target, Rio Tinto plans to use high-quality carbon credits from nature-based solutions. These credits will be capped at 10% of the company’s 2018 baseline emissions.

Most of these credits will come from Australian Carbon Credit Units (ACCUs), supporting compliance with the country’s Safeguard Mechanism. Rio Tinto remains committed to transparency in its emissions reporting. The company will clearly distinguish between its gross operational emissions and net emissions while also disclosing the volume and type of carbon credits used.

Advancing Carbon Capture and Mineralization Technologies

Rio Tinto is actively developing innovative ways to capture and store carbon emissions from fossil fuel use. In 2024, the company focused on identifying the most effective methods to capture low-concentration CO2 from aluminum smelters’ flue gas.

This effort includes adapting direct air capture for higher CO2 levels and modifying point-source technologies for lower concentrations, though both approaches remain in early development stages.

In early 2025, Rio Tinto partnered with Hydro to evaluate carbon capture technologies for aluminum emissions. Additionally, its collaboration with Carbfix is in the pipeline. They plan to begin CO2 mineralization at the ISAL site by 2028.

Meanwhile, at the Tamarack project in Minnesota, Rio Tinto recently completed a 1,137-meter exploratory well to assess the mineralization potential of local rock formations.

Designing an Insetting Program: A Step-by-Step Playbook for Procurement

Published

on

Insetting program design starts with your supplier map. The carbon claim comes much later.

Consider a coffee procurement team that funds a farm intervention before checking its sourcing data. The supplier aggregates coffee lots from several regions. The buyer lacks farm-level traceability. Another purchaser expects to report the same outcome. A more attractive project brochure solves none of these problems.

If the distinction between a value-chain intervention and a purchased credit is still open, read CCC’s Insetting vs Offsetting guide before you set the brief.

Insetting program design begins with the purchasing relationship and works outward. You need to decide 1) where an intervention belongs, 2) what business problem it addresses, 3) who pays for it, 4) how results will be measured, and 5) what the evidence will let you say about them. This five-step playbook turns that sequence into a procurement plan.

Step 1: Insetting program design starts with supplier mapping

Start with the commodities that matter most to your Scope 3 inventory and sourcing continuity. Ask finance for spend by supplier, sustainability for the emissions baseline, and category managers for origin and volume records. Then identify which suppliers can trace material to a jurisdiction, sourcing region, producer group, or individual land-management unit.

The level of traceability affects what you can account for. Under the GHG Protocol Land Sector and Removals Standard, the spatial boundary for purchased land-based products depends on the traceability associated with each volume. Farm-specific factors or removals require physical traceability through an acceptable chain-of-custody model. A contract with a tier-one trader, by itself, does not establish a link to the farms behind its deliveries.[1]

Build a first-pass table with five columns: commodity and annual volume; supplier and origin; current traceability level; land-use and production risks; and the business owner who can change the purchasing terms. Mark missing data plainly. A blank cell is cheaper to fix before a program starts than after a claim is drafted.

If your company sets an SBTi Forest, Land and Agriculture target (FLAG), keep its land-related target boundary separate from energy and industry emissions. The current FLAG guidance also requires relevant companies to assess primary deforestation-linked commodities in their value chains.[2]

Step 2: Choose a commodity and jurisdiction for a pilot

Select one supply corridor where the sourcing connection can be established and procurement has a reason to stay. A useful pilot has repeat purchases, suppliers willing to share records, an intervention matched to a diagnosed problem, and a defined plan to measure the result. Carbon potential alone is a poor selection rule if the supplier cannot deliver the crop your business needs.

Compare candidate regions on land-use risk, supplier concentration, local rights and tenure, the availability of baseline data, and exposure to drought, erosion, or forest conversion. Check the relevant legal requirements separately. A nature project does not satisfy a due-diligence obligation merely because it has a carbon method attached.

Consider a coffee buyer sourcing from two districts. In the first, producer-group records identify the farms, while recent dry seasons have increased rejected green coffee lots. In the second, deliveries pass through several intermediaries and farm origins are unknown. Pilot shade management in the first district, with local agronomic advice and quality checks built into the plan. The buyer can trace purchases there and test the intervention against a defined sourcing problem.

Use a short decision memo to record why the selected corridor beats the alternatives, what remains uncertain, and what would stop the pilot. That memo is the first control against a project drifting toward whatever happens to photograph well.

Step 3: Design the supplier engagement and commercial model

The intervention needs an owner on each side of the contract. Decide who supplies planting material or training, who maintains the practice, who bears the cost if a harvest disappoints, and how long the buyer expects to purchase from participating suppliers. Where smallholders participate, budget cash flow and technical support for practices that offer a later return.

Put these terms in a supplier agreement or pilot addendum. It should cover eligible farms and volumes, consent to data collection, access for monitoring, any land or carbon rights that matter, benefit sharing, and what happens if the purchasing relationship ends. Ask local counsel and producer representatives to review the arrangement. The Accountability Framework is a useful reference for supply-chain work involving forests, ecosystems, and human rights.[3]

Avoid assigning an automatic carbon benefit to the buyer. The contract should say which party has the right to report each outcome, how overlapping claims will be checked, and how any issued credits will be handled. A reduction reported in a buyer’s inventory cannot simply be sold for someone else’s offset claim without an accounting review. SBTi FLAG guidance excludes purchased credits used as offsets from near-term FLAG target achievement.[2]

Set commercial measures beside environmental ones: delivered volume, rejection rate, supplier retention, and procurement cost. They tell you whether the program works as a supply-chain investment, even if carbon accounting takes longer to resolve.

Step 4: Build monitoring, reporting, and verification before rollout

Agree on the baseline and data flow before paying for a full rollout. Identify the land units or sourcing regions in scope, the practices that change, the records suppliers already keep, and the additional measurements the program requires. Decide which data can come from field visits, transaction records, or remote sensing, and who checks each source.

For carbon, separate three questions. Did the practice happen? Did emissions or removals change under an applicable method? Can the buyer attribute a defensible share to its purchased goods without double counting? The GHG Protocol’s 2026 guidance includes dedicated chapters on spatial boundaries, data and methods, evaluating actions, credited outcomes, and assurance.[1] These are distinct jobs. A photograph of a planted tree answers only part of the first.

CCC’s MRV and Additionality article explains the separate evidence questions a project reviewer will ask.

Create an evidence file for every reporting period: dated supplier and farm records, purchase volumes, methods and emission factors, uncertainty, quality checks, and changes from the baseline. Specify who can challenge the data and how corrections are recorded. If a project also seeks credit certification, keep project accounting and corporate inventory accounting separate. The GHG Protocol says its land standard focuses on entity-level inventories and does not set the rules for credit certification.[4]

Start with the minimum viable measurement design that can survive review. Add complexity when the pilot tells you which data actually changes a decision.

Step 5: Decide what can be reported and claimed

Insetting program design needs reporting rules before the marketing copy. Procurement, sustainability, finance, and legal should agree on four distinct outputs: operational performance; observed land or nature outcomes; inventory effects, if the accounting criteria are met; and any separately issued credits. One dashboard can display them, but they should not share a single unqualified headline.

SBTi FLAG guidance allows certain land-based removals within a company’s operations or supply chain to contribute to FLAG pathways, subject to criteria including permanence, traceability, data quality, and allocation. It does not allow purchased offsets to meet near-term FLAG targets.[2] Eligibility therefore depends on evidence and the applicable target rules, not on calling an activity “insetting.”

Draft a claims register. For each proposed sentence, record the period, boundary, data owner, calculation method, reviewer, and whether the result is measured, estimated, or still a goal. If the evidence supports only “we funded a pilot with 200 farms,” say that. Do not turn a funding fact into a verified emissions reduction.

What good looks like by year three

Treat year three as a review point, not a promised payback date. A mature pilot should have mapped participating supply volumes, a stable supplier agreement, a repeatable data collection process, and a comparison of commercial and environmental results against the baseline. It should also have a documented answer for outcomes that cannot be included in the buyer’s inventory.

Scale only where the pilot improves a sourcing decision and the evidence can follow the product. If neither condition holds, redesign the intervention or change the corridor. A disciplined program can conclude that a site is unsuitable. That is useful procurement intelligence.

The Strategic Case for Nature-Based Carbon Investments

Published

on

Nature-based carbon investments deserve consideration when they address a specific business dependency and produce outcomes you can measure. Imagine Moonbucks, a global coffee roaster planning next season’s espresso blend. It is considering natural Grade 4 coffee from Jimma, in southwestern Oromia, Ethiopia. Its sourcing decisions affect the roasting schedule and the cash tied up in coffee purchases. Moonbucks needs to understand which measures could protect that supply, what they would cost and how it would judge the results.

1. Define the sourcing problem before choosing a project

Moonbucks needs a dependable component for its espresso blend. Its procurement team wants continuity of volume and an agreed cup profile. Replacing a shipment at short notice could require new sample approval and changes to the blend, and given the schedules for cultivation, processing, and freight delivery, is practically impossible. Moonbucks needs to get this right, and its initial concern is inconsistent deliveries. It commissions an assessment of the supplying farms and post-harvest chain. The questions cover land condition, harvest availability and whether drying or storage problems are affecting saleable lots.

This distinction changes the investment brief. A tree-planting proposal cannot be assumed to fix drying problems. Better storage cannot restore eroded land. The team must establish which problem exists before selecting the response.

CCC’s guide to finding nature-based solutions in your supply chain explains where to look. Here, the next task is to turn a broad concern into a testable proposal.

2. Develop nature-based carbon investments around the actual supply chain

The assessment would trace Moonbucks’ purchases back through the exporter and supplying producer groups. Which farms supply the contracted lots? Who controls land-management decisions? How long does the buyer expect to maintain the purchasing relationship?

Furthermore, Jimma natural Grade 4 cannot be treated as interchangeable with every Ethiopian coffee. Moonbucks would need to test any substitute against its own blend and quality requirements.

Suppose Moonbucks’ assessment identifies an opportunity to maintain shade trees and restore vegetation along exposed streambanks. The IPCC describes agroforestry as a way to store carbon in vegetation and soil, with potential benefits for erosion control and water quality.1 Moonbucks would need local advice on species, growing conditions and maintenance before deciding how these measures fit its sourcing plan.

The proposal now has a defined sourcing connection and a candidate intervention. The next steps are to test its effect on production, assess carbon eligibility and build the financial case.

3. Compare the proposal with other ways to protect supply

WBCSD’s Nature-based Solutions Blueprint recommends comparing nature-based options with other responses across their benefits and costs.2 For Moonbucks, that means evaluating the landscape proposal alongside drying improvements, storage controls and alternative sourcing arrangements.

The product’s natural-process designation matters. Moonbucks should examine the drying and dry-milling chain alongside land conditions. Its team would check storage practices, contamination risks and incoming-lot quality to see whether problems arise before or after the coffee leaves the farms.

The revised proposal might combine land stewardship with separate post-harvest controls. Each component needs its own purpose and budget. A sustainability label should not obscure which activity is expected to solve which problem.

The project develops as the evidence improves. Its scope should follow the diagnosis rather than preserve the first idea unchanged.

4. Establish what the carbon outcome could count toward

Moonbucks’ sustainability team now tests the proposed carbon case separately from the sourcing case. Is the objective a measurable change in Moonbucks’ value-chain emissions, verified credits for separate voluntary use, or distinct outcomes under carefully defined arrangements?

Scope 3 covers value-chain emissions. A purchasing relationship alone does not prove that a farm intervention can be included in Moonbucks’ inventory. The team needs an applicable accounting method, defensible boundaries and evidence supporting attribution.

SBTi’s FLAG Guidance (forest, land and agriculture), version 1.2, says purchased credits used as offsets cannot meet near-term FLAG or energy and industry targets. Eligible land-based removals are subject to accounting requirements.3 Moonbucks needs to test its proposal against those rules before including an outcome in its targets.

For Moonbucks’ Jimma proposal, maintaining existing trees and establishing new vegetation could involve different carbon questions. Specialists must examine the baseline and additionality, meaning what changes because the project proceeds. They must also assess measurement and the risk that stored carbon is lost. CCC’s MRV and additionality article introduces those tests.

Until that work is complete, Moonbucks should not budget an assumed Scope 3 reduction or credit-sale receipt. Direct emissions reductions remain the priority.

5. Build a financial case that survives weaker assumptions

Moonbucks’ finance team would now build a multi-year budget. UNEP’s State of Finance for Nature 2023 compares current finance with the investment needed to meet climate, biodiversity and land-restoration goals.4 The company would cost its proposed activities, farmer participation and ongoing monitoring. Verification, where required, is a separate expense. Maintenance and responsibility for replacing failed plantings must remain visible after the initial establishment budget ends.

Operational benefits need equally careful treatment. If fewer rejected lots reduce emergency purchasing, count that saving once. Do not add “supply resilience” as another financial benefit when it represents the same avoided cost.

Moonbucks should compare a base case with slower benefits, higher implementation costs and no carbon revenue. It should also distinguish production outcomes from quality and shipment outcomes. A single good harvest would not prove that the landscape intervention caused better delivery performance.

A project can remain worth funding even when its carbon case needs more work. That decision must rest on the operational evidence and the company’s objectives, without unsupported environmental claims.

6. Fund a pilot with a clear expansion decision

Moonbucks’ first approval would fund a bounded pilot, rather than commit the entire sourcing program. Before spending, Moonbucks would agree on participating farms, responsibilities and the evidence needed at review.

Its scorecard could track farmer participation, implementation costs and plant survival, alongside accepted coffee volumes and lot-quality results. Carbon measurements would follow the selected method. Farm-level traceability must connect the intervention to the actual sourcing relationship.

Suppose Moonbucks’ review later finds that storage changes explain most quality improvements, while the land measures need longer observation. Those findings would shape the next decision: expand the proven component, adjust the landscape work or pause further spending. They would not justify crediting all improvements to tree planting.

This gives nature-based carbon investments a practical place in a multi-year strategy. Funding increases as the evidence supports it, and the project can change direction before a larger commitment.
