Finance verified emissions reductions inside real value chains
Investors finance a named emissions reduction project in a real supply chain and hold one serialized, transferable credit per tonne. Future credits bought at validation pay for the implementation.
Climate exposure is easy to buy and hard to trust
Many industrial emissions reductions cost more per tonne than the carbon price the producer pays, if it pays one at all, and energy savings alone rarely close that gap. An inset credit adds a second source of revenue. Buyers in the same value chain pay for verified tonnes because the reduction sits in their own Scope 3. For a financier, a project with a thin energy-savings case then also has contracted credit volumes alongside the savings, each tied to a named plant, a baseline and a verification report.
What investors gain
Investors hold contracted volumes of verified credits from industrial projects, with buyers in the same value chain on the other side.
Exposure to verified emissions reductions
Each credit is one tonne of CO₂e verified by an independent body at a named project, with the baseline, the validation report and the verification report attached.
A live market
The Carbon3 marketplace is live, with real trading activity between members. Prices are set between buyer and seller.
Integrity by design
One holder per credit and a dated record of every issuance, transfer and retirement, which shortens due diligence and audit.
More than one exit
Sell to buyers in the same value chain or to other members, hold the credits, or retire them.
Inset credit prices are still forming. Nothing here is an offer or investment advice.
Future credits: finance before the reduction happens
Future credits are the main way to finance a project early. Realized credits are issued after each verification report.
Fund the implementation, hold the volume from the start
Future credits let an investor finance a project at validation and hold a contracted volume of credits from the start. They are usually priced lower than realized credits because the holder carries the delivery risk.
Future credits
From validation- For a planned reduction that has not happened yet.
- Issued to the project developer once the validation report confirms the project.
- Labeled Future on the Carbon3 registry.
- The holder carries the delivery risk, so they are usually priced lower.
Realized credits
After verification- For a reduction that has already happened.
- Issued to the project developer, one per tonne in the verification report.
- The independent verifier has confirmed the tonnes.
Both kinds are issued to the project developer and recorded on the Carbon3 registry. Every credit shows its category, so it is always clear which kind is held.
How an investor finances an emissions reduction
Finance can be tied to milestones, such as the validation report before implementation and the verification report before credits.
- 1Investor and supplier
Scoping and project definition
Choose a project on the Carbon3 platform or from the announced projects in the Data Hub pipeline. Review its scope, baseline, development plan and co-funders, and agree finance in exchange for a contracted share of credits.
- 2Independent verifier
Validation report
An independent verifier confirms the scope, baseline, methodology and additionality. This is a natural point for the first drawdown.
- 3Supplier
Implementation
The supplier installs the change and records the monitoring data.
- 4Independent verifier
Verification report
After each monitoring period, the verifier states the verified reduction in tonnes of CO₂e.
- 5Project developer, on the Carbon3 registry
Issuance to the project developer
Realized credits, one per tonne in the verification report, are issued to the supplier and recorded on the Carbon3 registry. Future credits can also be issued to it earlier, once the project is validated. They stay labeled Future, and buyers who take them carry the delivery risk.
- 6Supplier
Allocation
The supplier transfers the investor’s contracted share of credits. Every transfer is recorded.
- 7Investor
Sale or retirement
Sell to buyers in the chain or to other members, hold for later, or retire.
Finance in, verified credits out
The investor bridges the part of the cost that buyers will not pay up front.
Investor
Fund, lender or treasury
Supplier
Implements the project
Buyers
Companies in the same value chain
The investor’s share of credits is fixed in the contract. Each issuance and transfer is recorded on the Carbon3 registry.
How an investor gets paid back
This is the structure, step by step. Prices, volumes and timing are set in each financing agreement, and nothing here is a return or an offer.
- 1At validation
Finance the project
The investor agrees terms with the project developer, either a pre-payment for a contracted volume of future credits or a co-funding share with credits in proportion. Drawdowns can be tied to milestones such as the validation report.
Future credits - 2Implementation
The project is built
The project developer installs the change and collects the monitoring data. Future credits the investor holds stay labeled Future on the Carbon3 registry.
- 3After each verification
Verified tonnes come through
The independent verifier confirms the tonnes in a verification report. Realized credits for them are issued to the project developer, and those due to the investor are allocated to it on the registry.
Realized credits - 4Exit
Sell, hold or retire
The investor sells credits to buyers in the same value chain or to other members, at prices agreed between buyer and seller, holds them, or retires them. Every transfer is recorded.
If the project delivers fewer tonnes
The holder of future credits carries the delivery risk, and realized credits are only issued for verified tonnes. How a shortfall is handled is set in the financing agreement before implementation. See the methodology
Structure only. Nothing here is investment advice, a price or a projected return.
An investor funds most of a heat recovery retrofit
A glass container plant that supplies a beverage brand installs waste heat recovery on its furnaces. An investor pays most of the cost; the brand and the plant cover the rest.
Who pays what
| Funder | Share | Pays | Credits, years 1 to 5 | Of which future credits (years 1 and 2) |
|---|---|---|---|---|
| Investor | 60% | €900,000 | 15,120 t | 4,320 t |
| Buyer A (beverage brand) | 25% | €375,000 | 6,300 t | 1,800 t |
| Supplier | 15% | €225,000 | 3,780 t | 1,080 t |
| Total | 100% | €1,500,000 | 25,200 t | 7,200 t |
Future and realized credits in this example
1At validation
The 7,200 tonnes planned in years 1 and 2 are bought as future credits, so the money funds the implementation and the holders carry the delivery risk.
2After each verification
The 18,000 tonnes verified in years 3 to 5 are issued as realized credits, one per tonne in the verification report.
Cost per verified tonne
Spread over 5 years of credits, the project cost comes to €60 per verified tonne, a figure to compare with the internal carbon price or with the CBAM certificate cost an importer faces. Real prices are not shown.
Assumptions
- Project cost €1,500,000.
- Full rate of 6,000 t a year from year 3.
- No price or return is assumed. Prices are still forming.
- Credits are split in line with what each funder paid.
- One credit equals one verified tonne of CO₂e.
- No real companies, prices or projects. Fees are not shown.
- Illustrative split: the credits for years 1 and 2 are bought as future credits at validation; later years are taken as realized credits after each verification. The real split is agreed project by project.
Contracted credits over five years

Assumptions
- Same project and shares as the worked example.
- Nothing here is an offer or investment advice.
- Real results depend on verification.
- Illustrative split: the credits for years 1 and 2 are bought as future credits at validation; later years are taken as realized credits after each verification. The real split is agreed project by project.
Why supply-chain emissions reductions matter now
These are public figures and dates, each with its source.
Supply chains carry most of the footprint, and in 2023 companies reported supply-chain (Scope 3) emissions 26 times their own operational emissions.
Source: CDP and BCG, June 2024Few companies have a plan for those emissions yet, since only 15% of companies disclosing to CDP had set a Scope 3 target.
Source: CDP and BCG, June 2024Those emissions carry a price, since at $75 per tonne the upstream emissions of manufacturing, retail and materials firms imply a carbon liability above $335 billion.

What the credits are, and are not
Demand depends on how buyers can report the credits. These are the rules that decide it.
Counting each tonne once
- What the standard is
- Double counting happens when two companies claim the same tonne, when one tonne is sold twice, or when a reduction is credited by two programs. Standards such as the SBTi’s now require serialized tracking to prevent it.
- A reduction in the company’s own supply chain
- Several companies in one chain can fund the same project. Each receives its own serialized credits, so no tonne has two holders.
- One in its industry, outside its chain
- The same rule applies wherever the tonne sits: one serial number, one holder, and no credit for a reduction already credited by another program.
- What an inset credit does
- Each credit has a serial number and exactly one holder on the Carbon3 registry. A transfer moves it rather than copying it, and retirement closes it permanently. A reduction already credited elsewhere is excluded at validation.
GHG Protocol: Scope 3 Standard
- What the standard is
- The Greenhouse Gas Protocol sets the accounting rules most companies use for their emissions. Its Corporate Value Chain (Scope 3) Standard, published in 2011, covers the emissions in a company’s value chain in 15 categories, from purchased goods and transport to the use of sold products. It has no market-based method for Scope 3, so purchased certificates or credits do not change the Scope 3 figure, unlike electricity in Scope 2.
- A reduction in the company’s own supply chain
- A reduction at a supplier the company buys from lowers its Scope 3 inventory when it shows up in the data the company uses, for example a supplier-specific emission factor for the goods it purchases. A spend-based average will not show it.
- One in its industry, outside its chain
- A reduction at a producer outside the company’s own supply chain is not part of its inventory under any method. It can be disclosed separately as an action, not as a lower Scope 3 figure.
- What an inset credit does
- When a supplier in the buyer’s own chain reduces emissions, the buyer’s Scope 3 goes down through lower supplier emissions data. The inset credit is the proof of that emissions reduction and who funded it, and it is not counted a second time. An emissions reduction outside the buyer’s own chain is reported separately, not as a lower Scope 3 figure. The GHG Protocol’s Actions and Market Instruments workstream is developing a market-based approach for Scope 3. A consolidated draft is expected for public consultation in the second quarter of 2027, and the revised standard in the fourth quarter of 2028. Each Carbon3 credit records the supplier, project, baseline and verification report, so it can be reported under the current rules and reassessed under the new ones.
Science Based Targets initiative (SBTi)
- What the standard is
- The SBTi validates whether a company’s emissions reduction targets are consistent with climate science. Its Corporate Net-Zero Standard V2.0 was published on 11 June 2026. Validations under it open on 1 February 2027, and it becomes mandatory for new target submissions from 1 February 2028. Targets already validated under the earlier version stay valid for their cycle. Target ambition is always set on the company’s physical inventory.
- A reduction in the company’s own supply chain
- Reductions that show up in the company’s inventory support emissions reduction claims. A project implemented by or on behalf of the company in its own value chain, with measured outcomes reported in proportion to its contribution, can support target implementation and an “alignment” claim.
- One in its industry, outside its chain
- Action in a shared system the company draws on, such as a supply shed or logistics network, or at sector level, counts only where direct action in its own chain is constrained. It supports a separate “system contribution” claim, reported apart from the inventory.
- What an inset credit does
- Projects must be measured, additional and verifiable. Their outcomes must be uniquely attributed, with serialized tracking to prevent double counting. Credits a company sells on cannot also count for that company. The SBTi plans interim guidance on reporting projects and market instruments for consultation in the fourth quarter of 2026, so how a received inset credit is assessed is not yet fully settled.
EU rules on green claims
- What the standard is
- From 27 September 2026, EU consumer law (Directive 2024/825) bans claims that a product has a neutral, reduced or positive climate impact when the claim rests on compensating emissions with credits. Claims about measured reductions in the product’s own life cycle remain possible if they are substantiated.
- A reduction in the company’s own supply chain
- A product claim can rest on measured, substantiated reductions in that product’s own life cycle, which includes reductions at its suppliers.
- One in its industry, outside its chain
- A reduction outside the product’s life cycle cannot support a claim that the product has a neutral, reduced or positive climate impact.
- What an inset credit does
- Inset credits support Scope 3 reporting and progress towards targets, not product neutrality claims. A product claim has to rest on measured reductions in that product’s life cycle. Credits never replace a company’s own emissions reductions.

Questions from investors
Credits stay tied to the value chain where the emissions reduction happened. Holders are the supplier, the buyers and the investors or lenders that financed the project, plus members who buy credits from them. Each credit has one holder at a time, and every transfer is recorded on the Carbon3 registry.
