Carbon Forward Sales and Pre-Issuance Funding for Voluntary Carbon Projects With Call Options and Put Options
Carbon forward sales can convert future verified carbon credits into present project funding. For voluntary carbon projects, the structure works only when delivery risk, MRV risk, registry risk, price risk and buyer claim risk are documented with discipline.
Carbon Forward Sales In The Voluntary Market
A carbon forward sale is a contract for the future delivery of carbon credits that have not yet been issued. The buyer agrees to purchase eligible credits at a fixed price, floating price, floor price or formula-based price once the project reaches validation, verification and registry issuance.
For a voluntary carbon project, this can create a practical route to pre-issuance funding for carbon projects. The project sponsor receives cash before credit issuance, then delivers credits later from the project’s verified output. The commercial problem is simple. The buyer wants future supply. The project needs funding before the registry has issued credits.
That funding can support PDD preparation, MRV systems, fieldwork, community payments, planting, project implementation, validation, verification, registry costs and sponsor working capital. It should never be treated like free cash. The forward buyer is taking delivery risk and will usually demand pricing, covenants and remedies that reflect that risk.
The Main Structures
| Structure | How It Works | Best Use | Main Risk |
|---|---|---|---|
| Forward Sale | Buyer agrees today to purchase future eligible credits at a fixed or formula price. | Projects with credible issuance schedule and buyer demand. | Shortfall, delayed issuance or credits failing buyer eligibility criteria. |
| Prepaid ERPA | Buyer advances cash before delivery under an emission reduction purchase agreement. | Pre-issuance funding for carbon projects with strong legal rights and MRV plan. | Buyer overexposure if the project fails to issue credits. |
| Carbon Stream Agreement | Investor funds the project in exchange for a share of future credits or sale proceeds. | Projects needing development capital across multiple issuance periods. | Long-dated project performance and governance risk. |
| Call Option | Buyer pays for the right to purchase future credits at a strike price. | Buyers seeking supply access without full forward purchase obligation. | Project may receive less upfront cash than under a prepaid forward. |
| Put Option | Project receives the right to sell credits to a buyer or investor at a floor price. | Projects seeking minimum price support for financing or budgeting. | Buyer must absorb downside price exposure if market prices fall. |
| Put-Call Collar | Project has downside price protection and buyer has upside purchase rights. | Balanced structures where both parties share market price risk. | Requires tight drafting around eligible credits, exercise timing and settlement. |
How A Carbon Forward Sale Funds A Project Before Issuance
Project Need
Early-stage voluntary carbon projects often need funding before credits exist. Costs may include methodology work, PDD drafting, baseline studies, MRV equipment, field sampling, stakeholder engagement, safeguards, validation and verification preparation.
Buyer Motive
Forward buyers may want early access to scarce future supply, known pricing, specific project geography, nature-based exposure, removal credits, co-benefits, or credits tied to a long-term procurement strategy.
Funding Mechanics
The buyer can pay a deposit, milestone advance, prepaid purchase amount or staged funding. Payment may be released against validation, monitoring milestones, verification or registry issuance.
Delivery Mechanics
The seller delivers eligible issued credits into the buyer’s registry account. The contract should define vintage, standard, methodology, geography, credit type, buyer claim status and replacement credit rights.
Call Options On Future Carbon Credits
A call option gives the buyer the right to buy future carbon credits at a defined strike price or formula. The buyer is usually paying for access, not taking full purchase obligation on day one.
For voluntary carbon projects, call options can be useful where the buyer wants priority access to future credits but the project is too early for a full prepaid forward. The buyer may pay an option premium, provide technical support, fund part of MRV, or agree to purchase credits only if they meet specified eligibility criteria.
Example structure. A corporate buyer pays an option premium for the right to purchase up to 200,000 issued VCUs over five years at a strike price of USD 18 per credit, subject to Verra issuance, defined methodology, no double counting, safeguards compliance and accepted buyer claim status.
Put Options For Price Support
A put option gives the project sponsor the right to sell future credits to a buyer, investor or fund at a defined floor price. This can help the project show minimum revenue support when raising development capital.
Put options are commercially harder to obtain because the buyer absorbs downside price risk. They may work when the buyer has a long-term demand profile, when the project has strategic value, or when the option is part of a broader stream financing or offtake package.
Example structure. A carbon stream investor grants the project a put right for eligible issued credits at USD 12 per credit, while receiving a call right above that level for part of the project’s annual issuance. The put protects the project. The call gives the investor upside access.
What The Contract Must Define
- Eligible credit definition covering registry, standard, methodology, project type and credit vintage.
- Project status covering concept, PDD, validation, monitoring, verification and issuance stage.
- Delivery schedule with expected issuance dates, transfer deadlines and grace periods.
- Purchase price using fixed price, floating price, floor price, collar or index-based formula.
- Prepayment terms including deposit, staged advance, escrow, milestone release and repayment triggers.
- Shortfall remedies covering replacement credits, make-whole payments, delivery extensions or refund rights.
- Carbon rights proving the seller can generate, receive, sell and transfer credits.
- MRV covenants requiring monitoring, reporting, data retention and verification readiness.
- Registry controls covering account authority, serial numbers, transfer process and retirement instructions.
- Buyer claim status covering VCM use, CORSIA, Article 6 authorization or corresponding adjustment needs.
- Force majeure covering fire, drought, political action, registry delay and methodology change.
- Security package covering pledge of contract rights, account control, escrow, parent support or step-in rights where available.
The Pricing Problem
Pre-issuance carbon credits are worth less than issued credits because they carry project delivery risk. The price discount should reflect stage, methodology confidence, credit type, buyer claim utility, country risk, registry risk, issuance timing and credit quality.
A project with validated design, clear land rights, strong MRV and a signed VVB pathway should price better than a concept-stage project with only a projected credit volume. The difference can be brutal. Buyers do not fund dreams. They fund delivery probabilities.
| Project Stage | Funding Position | Commercial Interpretation |
|---|---|---|
| Concept Stage | Small option premium or development advance. | High risk. Buyer should avoid large prepayments unless rights and project control are unusually strong. |
| PDD Prepared | Milestone-based forward or option structure. | Moderate early risk. Methodology and baseline still need validation. |
| Validated Project | Forward sale, prepaid ERPA or stream agreement. | Stronger funding case. Verification and issuance risk remain. |
| Verified But Not Issued | Short-tenor bridge or purchase advance. | Lower risk if registry issuance path is clear. |
| Issued Credits | Spot sale, repo-style facility or inventory finance. | Credit exists. Price risk and buyer claim fit become the main issues. |
Forward Sales Need A Clean Carbon Rights Chain
A buyer cannot safely prepay for future credits if the seller cannot prove the right to deliver them. The project file should connect land rights, carbon rights, project proponent authority, registry account control and credit sale authority.
For a voluntary carbon project, this usually means the landowner, local sponsor or concession holder signs a carbon rights assignment or carbon project development agreement with the project company. The project company then signs the forward sale, prepaid ERPA, option agreement or carbon stream agreement with the buyer or fund.
Clean chain. Land rights and carbon rights move from the landholder or local sponsor to the project vehicle. The project vehicle registers the project, manages MRV and receives issued credits. The buyer receives eligible credits under the forward sale or option exercise.
High Integrity Still Controls The Financing
Forward sales should not be used to finance weak credits. A buyer paying before issuance should underwrite the same integrity factors that a serious buyer checks at purchase. That includes additionality, conservative baseline, permanence, leakage, safeguards, stakeholder consent, no double counting, registry process and credible MRV.
ICVCM’s Core Carbon Principles provide a quality benchmark for high-integrity credits. VCMI’s Claims Code focuses on how companies use and claim carbon credits after meeting or showing progress toward emissions reduction targets. Those two areas matter for forward buyers because future delivery is only valuable if the credit can be used credibly when it arrives.
Best Transaction Package For A Voluntary Carbon Project
For most early-stage voluntary carbon projects, the cleanest commercial package is staged. Start with a modest development advance or option premium. Increase funding after land rights, carbon rights, methodology fit, validation and MRV readiness are confirmed.
Stage One
Option agreement or small pre-development advance tied to exclusivity, diligence access, carbon rights review and methodology screening.
Stage Two
Prepaid ERPA or carbon stream agreement after PDD preparation, land and carbon rights confirmation, safeguards review and VVB engagement.
Stage Three
Larger forward purchase or stream financing after validation, monitoring evidence and credible issuance schedule.
Red Flags In Carbon Forward Sales
- No carbon rights assignment. The seller cannot prove it owns or controls the future credits.
- Loose eligible credit language. The contract does not define registry, methodology, vintage, project type or buyer claim status.
- No shortfall remedy. The buyer has no practical remedy if credits are delayed or never issued.
- Overfunding too early. A large prepayment is made before validation, MRV plan or legal rights are confirmed.
- Article 6 confusion. The seller implies authorization or corresponding adjustment without host-country documentation.
- Weak replacement credit rights. Replacement credits are allowed but not defined by standard, vintage, quality or claim utility.
- No MRV covenants. The seller is not contractually required to keep the evidence trail needed for verification.
Transaction Takeaway
Carbon forward sales can be a powerful tool for pre-issuance funding for carbon projects. They turn future carbon credit delivery into a financing asset before credits exist. Call options help buyers secure future supply. Put options help projects create price support. Collars can balance both sides.
The structure only works when the project file is real. A forward contract cannot fix weak land rights, missing carbon rights, poor MRV or inflated credit projections. The bankable version is disciplined, staged and tied to verifiable project milestones.

What is a carbon forward sale?
A carbon forward sale is a contract to sell future carbon credits before they have been issued. The buyer agrees to purchase eligible credits after validation, verification and registry issuance, usually at a fixed price or formula price.
Can carbon forward sales provide pre-issuance funding for carbon projects?
Yes. A prepaid forward sale or prepaid ERPA can provide funding before credit issuance. The funding should be staged against project milestones such as carbon rights confirmation, PDD preparation, validation, monitoring, verification and issuance.
What is a call option on carbon credits?
A call option gives a buyer the right to purchase future carbon credits at a defined strike price or formula. It is useful when the buyer wants priority access to future supply without committing to a full purchase at the outset.
What is a put option on carbon credits?
A put option gives the project sponsor the right to sell future credits at a defined floor price. It can support financing by giving the project a minimum revenue case, subject to credit delivery and eligibility conditions.
What should a carbon forward sale agreement include?
It should define eligible credits, registry standard, methodology, vintage, project boundary, delivery timing, price, prepayment terms, shortfall remedies, MRV covenants, replacement credit rights, buyer claim status and governing law.
Is a carbon forward sale the same as a carbon stream?
No. A forward sale usually covers the purchase of future credits. A carbon stream usually funds the project in exchange for a share of future credits or sale proceeds over time. The structures can overlap in practice.
