Spot vs Forward vs Offtake: How Indian Companies Should Structure Carbon Credit Purchases in 2026
Most Indian companies buy carbon credits the same way they buy stationery: one purchase order, one delivery, done. That works for a small carbon-neutral claim. It stops working the moment your volumes grow, your claims are scrutinised, or your obligations under the Carbon Credit Trading Scheme (CCTS) begin to bite. At that point the question is no longer only ‘which project?’ but ‘which contract structure?’
This guide explains the three structures a buyer meets in practice, spot, forward and offtake, what each one costs you in risk, and how a sustainability lead or CFO in India can combine them. If you are earlier in the journey, start with our step-by-step guide to buying carbon credits in India.
Spot, forward and offtake: what you are actually buying
The three structures differ mainly in when the credits exist and when you pay.
Spot: the credits are already issued and sit in a registry account. You pay at the day's price and the credits are transferred and retired, usually within days. You carry price risk but almost no delivery risk.
Forward: you contract today for credits to be issued later, typically over one to five years, often paying upfront or in milestone tranches. You carry issuance risk: the project may under-deliver, be delayed, or have its methodology revised.
Offtake: a long-term agreement, commonly five to fifteen years, under which you take credits as the project issues them each year. It is mostly used for scarce, higher-cost categories such as durable carbon removal, and it comes with make-good, reversal and quality-floor clauses.
These ranges are market conventions, not legal categories, so always read the actual contract. A broker's ‘forward’ can be another developer's ‘offtake’.
What the numbers say about price and risk
Global data gives useful context for how these structures are used. Sylvera's 2025 figures, as reported by CarbonCredits.com, show roughly 168 million credits retired on the spot market in 2025, while announced offtake deals reached about $12.25 billion, up from about $3.95 billion in 2024. The implied average offtake price was around $160 per credit against roughly $6 on the spot market.
The gap between spot and offtake prices reflects what is being bought, not the contract type: offtakes mostly fund expensive removals, while spot is dominated by cheaper avoidance credits.
Advisory commentary such as Regreener's 2026 pricing note suggests forward contracts are typically priced 15 to 30% below the expected future spot price, with fixed, indexed or escalating pricing (often 2 to 5% a year). Treat that as a negotiating reference rather than a rule: it is one firm's view, and Indian project types will price differently. For India-specific ranges, see our carbon credit price guide for 2026.
When spot is the right call for an Indian buyer
Spot suits buyers whose need is small, one-off or time-bound. Examples include offsetting a single event, closing a modest residual-emissions gap before an annual report, or testing a project type before committing.
Advantage: you see exactly what you are buying, including the vintage, registry serial numbers and retirement certificate, before you pay.
Advantage: no counterparty exposure to a project that has not yet delivered.
Drawback: you buy at whatever the market charges that day, and high-integrity supply from specific project types can be thin when you need it.
Drawback: repeated small purchases cost more in time and diligence than one planned programme.
When forward and offtake contracts earn their place
If your emissions gap is recurring and sizeable, buying year after year on the spot market leaves you exposed to price swings and to being unable to source the quality you want. Forward and offtake contracts address that, and they can also reduce your cost per tonne, but only if you manage the delivery risk.
Consider a forward or offtake structure when:
You have a multi-year net-zero or carbon-neutral commitment with predictable annual volumes.
You want priority access to a specific project type, for example agroforestry, biochar or improved cookstoves in India, that is hard to source at volume.
You are an obligated entity planning for CCTS targets and want a view of future costs. Note that compliance obligations are met with Carbon Credit Certificates (CCCs), not voluntary credits, so forward contracts for voluntary credits do not substitute for compliance.
You can tolerate paying before delivery, and your finance team has agreed how prepayments will be treated. Our note on GST, income tax and accounting treatment is a good starting point.
Contract terms that protect a forward buyer
The real protection in a forward or offtake deal sits in the clauses, not the headline price. Before signing, insist on clear answers to these points, and see our 27-question carbon credit RFP template for the full list.
Replacement or make-good: what happens if the project under-issues, is suspended, or a methodology is revised? You should get replacement credits of equal quality or a refund, not just an apology.
Staged payments: tie tranches to milestones such as registration, first verification and first issuance, rather than paying everything on signature.
Quality floor: specify registry, methodology, vintage window and, where relevant, whether the credits carry the ICVCM Core Carbon Principles label.
Reversal and buffer terms: for nature-based credits, confirm how reversals are covered.
Retirement on your behalf: credits should be retired in your name or your nominated beneficiary's, with a registry-verifiable certificate.
Pricing mechanism: fixed, indexed or escalating, and who bears currency movement if the contract is in dollars or euros.
A practical blended approach
Most mature buyers do not choose one structure. One reasonable pattern: hold a core of long-dated volume for your predictable annual need, cover the next one to two years with forwards on projects you have diligence on, and keep a smaller spot allocation to true up at year end once your inventory is final. Regreener suggests mixes such as 10 to 30% spot, 20 to 40% forward and 40 to 70% offtake for very risk-averse long-term buyers, but those proportions assume large, removal-heavy portfolios and are unlikely to fit a mid-sized Indian company's first programme. A sensible starting point is mostly spot plus one pilot forward contract with a developer you have audited.
Keep the market backdrop in view as well. Our H2 2026 voluntary carbon market outlook covers supply and pricing trends, and the CERC 2026 trading rulebook explains how CCC trading is meant to work on power exchanges. Rules and timelines are evolving, so confirm details against the official CERC and BEE notifications before you commit to any plan.
