Building a Carbon Credit Portfolio in India (2026): How to Split Your Budget Across Project Types
Most Indian companies buy carbon credits the way they buy stationery: one project, one invoice, one retirement certificate. That works for a first purchase. It stops working once the volume grows, an auditor asks questions, or a single project underdelivers. A portfolio approach, spreading a budget across several project types and vintages, is how mature buyers manage price, quality and reputational risk at the same time.
This guide is for the sustainability lead, CFO or procurement head who has already decided to buy and now needs to decide what to buy, in what proportion. If you are still at the first step, start with our step-by-step guide to buying carbon credits in India.
Why a single-project purchase is the riskiest option
A one-project purchase concentrates three risks. Delivery risk: the project may issue fewer credits than expected, or later. Quality risk: if that one project is criticised, your entire claim is exposed. Price risk: you lock the whole budget at a single point in the market.
Quality risk deserves particular attention. According to a March 2026 analysis by Senken citing Calyx Global data as of November 2025, only about 8% of rated projects were eligible for the ICVCM's Core Carbon Principles (CCP) label. The same analysis reports that the ICVCM had assessed more than 60 methodologies, approving 38 and rejecting 22. A buyer who picks credits without checking methodology status can easily end up holding a large share of unlabelled supply. Our explainer on the CCP label for Indian buyers covers how to read this.
A portfolio does not make a weak credit strong. It stops one weak credit from defining your whole climate claim.
The four building blocks of a buyer portfolio
Most corporate portfolios can be described as four buckets. The right mix depends on your purpose: voluntary carbon-neutral claims, supplier or customer expectations, or preparation for CCTS compliance.
Durable removals. Biochar and engineered removals store carbon for long periods and sit at the high-quality end. They are also the most expensive. See our biochar buyer's guide for how Indian projects are structured.
Nature-based removals. Afforestation, reforestation and revegetation (ARR) and mangrove projects. Co-benefits are visible and easy to communicate, but permanence and survival need monitoring. Our ARR and VM0047 guide explains what to check.
Avoidance and reduction credits. Cheaper per tonne. Quality varies widely by methodology, so only CCP-labelled or well-assessed methodologies belong here. The trade-offs are set out in nature-based vs avoidance credits.
Compliance-grade units. If your company is, or may become, an obligated entity under India's CCTS, Carbon Credit Certificates (CCCs) are a separate instrument with a separate purpose. Do not treat them as interchangeable with voluntary credits.
What each bucket costs: reference ranges for 2026
Prices differ sharply by project type, which is exactly why mixing matters. Senken's published 2026 ranges, based on its own transaction data and developer offers and last updated 15 September 2026, are indicative only:
Biochar: roughly €105 to €200 per tonne. For Indian biochar the same source cites about €105 for artisanal and €120 to €150 for industrial projects.
Mangrove restoration: roughly €50 to €75 per tonne.
ARR: roughly €22 to €50 per tonne.
Improved forest management: roughly €25 to €30 per tonne.
REDD+: roughly €12 to €15 per tonne.
Direct air capture: from about €450 to over €1,000 per tonne.
These are single-source indicative ranges, not quotes, and they are in euros. Your delivered price will depend on vintage, registry, volume, co-benefits and contract structure. For a rupee view of what Indian buyers typically pay, see our India carbon credit price guide.
A simple way to split the budget
There is no universal ratio, and anyone quoting one without knowing your footprint and goals is guessing. A workable method has four steps:
Fix the purpose first. A claim that credits will be retired against residual emissions needs higher-quality, ideally CCP-labelled units. Contribution-style funding of local projects can tolerate more variety.
Set a floor for quality. Decide in writing which registries, methodologies and verification standards are acceptable. Reject anything outside the list before price comparison begins.
Cap concentration. Many buyers limit any single project or developer to a defined share of the total, and spread delivery across more than one vintage year.
Weight by risk appetite. A conservative buyer tilts toward removals and labelled credits and accepts a higher average price. A cost-sensitive buyer with a lower-stakes claim tilts toward verified nature-based and avoidance units, but keeps documentation tight.
Illustratively, a mid-sized manufacturer might hold a small durable-removal tranche for its most visible claims, a larger nature-based tranche with local co-benefits, and a modest avoidance tranche limited to labelled methodologies. Treat that as a template to adapt, not a recommendation.
Contract and timing choices that protect a portfolio
Portfolio logic also applies to how you buy. Splitting volume between immediate spot purchases and forward offtake agreements reduces timing risk and smooths price exposure; we compare the options in spot vs forward vs offtake. Whichever route you use, insist on clear delivery, replacement and retirement terms. Our checklist of purchase agreement clauses lists the ones that matter most.
Finally, plan the accounting and tax treatment before you sign, and keep retirement evidence for every tranche. A portfolio with five projects means five serial-number trails to reconcile at audit.
Regulatory details such as CCTS rules and ICVCM assessments change frequently. Please confirm current positions against the official notifications from the Ministry of Power, BEE and the ICVCM before committing budget.
