The Carbon Credit Trading Scheme (CCTS): India's own carbon market

How did India's carbon market evolve?

India's carbon market did not begin with CCTS. It grew out of two decades of energy-efficiency regulation, starting with the Energy Conservation Act, 2001, and the Perform, Achieve and Trade (PAT) scheme that followed under it, which set energy-efficiency obligations for energy-intensive industry and allowed the resulting savings to be traded as certificates.

The lineage matters for anyone reading the scheme for the first time. CCTS inherits the institutional habits of PAT — sectoral targets, certificate trading, an administering agency — and extends them from energy consumed to greenhouse gases emitted. That is a larger change than it sounds: energy saved can be metered directly, while emissions avoided or removed have to be established against a counterfactual baseline.

How does the Indian Carbon Market work?

The Indian Carbon Market under CCTS runs on two mechanisms that reach two different populations. The compliance mechanism applies to obligated entities that have been given greenhouse gas emission intensity (GEI) targets; the offset mechanism opens the market to eligible projects developed by entities that carry no such obligation.

The distinction is worth holding onto, because the two mechanisms fail in different ways. Compliance turns on the accuracy of an entity's own emissions and production accounting. The offset mechanism turns on whether a project's claimed reductions would have happened anyway — which is a question about a scenario that never occurred, and therefore about the quality of the evidence assembled around it.

Who takes part in CCTS, and in which role?

CCTS assigns distinct roles, and a project developer entering the market needs to know which one it occupies. Four roles carry most of the weight:

• Obligated entities — industrial and energy-intensive entities in notified sectors, holding greenhouse gas emission intensity (GEI) targets set according to their sector and operational performance.
• Non-obligated entities — organisations without a GEI target, which can still participate by developing eligible projects under the offset mechanism.
• Bureau of Energy Efficiency (BEE) — the agency that has developed the methodologies for offset activities across energy, industry, waste, agriculture and forestry.
• Accredited Carbon Verification Agencies (ACVAs) — the independent bodies that verify reported reductions and the calculations behind them under the CCTS framework.

Nothing in the scheme lets a participant occupy two of these roles at once for the same tonne. Separating who claims a reduction from who confirms it is the structural reason a verified credit means more than a reported one.

Why do methodologies matter in the carbon market?

A methodology is what turns a real-world activity into a countable quantity of carbon, and without one there is no credit. Reducing emissions is not by itself sufficient: a standardised methodology is required to establish how those reductions are quantified, against what baseline, and within what boundary. Under the CCTS offset mechanism, the Bureau of Energy Efficiency has developed methodologies for activities in energy, industry, waste, agriculture and forestry.

• Reference scenario — what would have happened without the project.
• Project boundary — the physical and organisational limits of what is counted.
• Relevant sources and sinks of greenhouse gases within that boundary.
• Additionality — whether the activity depended on carbon-market incentive.
• Project and baseline emissions — the two quantities whose difference becomes the credit.
• Leakage — emissions displaced outside the boundary rather than avoided.
• Parameters to monitor, and the frequency at which they are monitored.
• Emission factors used to convert measured activity into tonnes of CO₂ equivalent.
• Net emission reductions or removals — the final creditable quantity.

Methodologies are therefore the technical basis of the carbon market, and the reason two projects doing visibly similar work can generate very different numbers of credits. They exist to make reductions measurable, consistent and verifiable rather than merely plausible. For a worked example of how one methodology handles a single project type, see our explainer on VM0047, Verra's afforestation, reforestation and revegetation methodology.

What is MRV, and why is it the backbone of CCTS?

MRV stands for monitoring, reporting and verification, and it is the process that decides whether a claimed reduction becomes a credit. Under CCTS, independent verification is carried out by Accredited Carbon Verification Agencies (ACVAs), and accurate verification is difficult to achieve without a robust monitoring and reporting record underneath it.

• Monitoring — collecting the relevant project data, which depending on the activity may include energy consumption, fuel use, production volumes, methane recovery or renewable electricity generation.
• Reporting — documenting that information and the resulting emission reduction calculations in line with the applicable requirements.
• Verification — independent review of the reported information and the calculations by an accredited agency.

MRV is where most projects actually stall, because the burden is continuous rather than one-off: a crediting period runs for years, and the monitoring record is examined again at every verification cycle. This is the part of the lifecycle that digital MRV exists to address — capturing each observation already bound to a location, a timestamp and the methodology requirement it satisfies, rather than reconstructing the evidence months later from spreadsheets.

Why does additionality matter?

Additionality is the test of whether a project's climate benefit is real in market terms, and it asks one question: would the emission reductions or removals have happened without the carbon-credit incentive? If the activity would have gone ahead regardless of carbon-market participation, its claimed climate benefit may fail the additionality test.

Demonstrating additionality is how a market distinguishes carbon-finance-driven action from business-as-usual activity that has been relabelled. It is also the claim hardest to evidence after the fact, which is why baseline and additionality assessment sits early in the project lifecycle rather than at the point of issuance.

What does a CCTS project lifecycle look like?

A CCTS offset project moves through a defined sequence designed to establish that reductions or removals are real, measurable and verifiable before any certificate is issued. For an eligible project, the journey runs through eleven stages:

• 1. Project identification — the activity and the site are defined.
• 2. Eligibility assessment — whether the activity and location qualify under the scheme.
• 3. Methodology selection — which approved methodology governs the quantification.
• 4. Baseline and additionality assessment — the counterfactual scenario and the case that the project depends on carbon finance.
• 5. Project documentation — the design, boundary, monitoring plan and calculations, written up.
• 6. Registration — the project enters the system under the applicable procedures.
• 7. Monitoring — the parameters set out in the methodology are tracked over the crediting period.
• 8. Emission reduction or removal calculation — monitored data is converted into tonnes of CO₂ equivalent.
• 9. Independent verification — an Accredited Carbon Verification Agency reviews the report and the calculations.
• 10. Credit issuance — Carbon Credit Certificates are issued for the verified quantity.
• 11. Trading or utilisation — certificates are traded or used against an obligation.

At every stage the project is assessed, documented and monitored, and independent verification sits deliberately between the project's own calculation and the issuance of any certificate. The sequence also explains why carbon projects take as long as they do: the evidence for stage nine has to be designed at stage four. Our guide to how a forestry carbon project actually gets built walks through the equivalent pipeline on the voluntary market side, where the same ordering problem appears.

What does CCTS mean for businesses?

CCTS is simultaneously a compliance requirement and a commercial opportunity, and which one it is depends on whether an organisation holds a GEI target. Obligated entities need to understand their emission intensity targets and identify credible pathways to reduce emissions; non-obligated organisations can develop eligible carbon projects under the offset mechanism.

• Sound methodology — the right approved methodology, correctly applied.
• Accurate data — measured, not estimated after the fact.
• Robust MRV — monitoring and reporting a verifier can actually follow.
• Transparent accounting — assumptions and boundaries stated openly.
• Independent verification — the step that converts a claim into a credit.

For both populations the fundamentals are identical, which is the most useful thing to take from the scheme: the future of India's carbon market rests not on the number of credits generated but on the credibility of the climate impact those credits represent.

What is the future of CCTS?

The Indian Carbon Market is still developing, but its direction is becoming clearer: the compliance mechanism is beginning to extend across energy-intensive sectors, while the offset mechanism continues to build out methodologies, procedures and its verification ecosystem. Five areas are likely to matter most as the market matures.

• Greater sectoral participation — more sectors and project activities as the framework and methodologies develop.
• Stronger MRV systems — reliable monitoring, digital data management and independent verification, which market credibility depends on.
• Demand for high-quality carbon projects — closer attention to genuine additionality, transparency, long-term carbon storage and clear, measurable climate benefits.
• Carbon-removal solutions — nature-based and technology-based removals, where they meet the relevant methodological and monitoring requirements.
• Alignment with global carbon markets — interaction with international climate frameworks, including Article 6 of the Paris Agreement, as the applicable rules and mechanisms evolve.

Read together, those five point the same way: the scarce commodity in India's carbon market will not be projects, it will be defensible evidence. Two of the five — stronger MRV and demand for high-quality projects — are measurement problems before they are policy problems.

How does Flora Carbon AI fit into India's carbon market?

Flora Carbon AI builds the measurement layer that both CCTS mechanisms ultimately rely on. Flora Carbon AI is a Kolkata-based company that develops nature-based carbon projects and builds AI-powered digital MRV — field data capture, satellite monitoring and registry-ready reporting — so that emission reductions and removals can be evidenced rather than asserted. Four tools cover the lifecycle stages where evidence is created:

• FloraTrace — QR-based tree tagging and GPS plot tracking, so each field observation is anchored to a verifiable point on the ground.
• FloraScope — satellite land screening, land-use and land-cover mapping, and change detection over time, without requiring GIS expertise in-house.
• FloraCarbon Calculator — sequestration modelling across Gold Standard, Verra (VCS) and CDM methodologies.
• FloraGPT — support for methodology selection, project documentation drafting and audit preparation.

That work is already running on the ground rather than on paper: mangrove reforestation monitoring in the Sundarbans, a Gold Standard grouped agroforestry programme with around 100 farmers in Purulia district, West Bengal, and a 2,000-plus farmer agroforestry project in Timor-Leste, alongside work in the Amazon region and East Africa. Flora Carbon AI aligns its methodology work with Gold Standard, Verra (VCS), Plan Vivo, ICR and CDM frameworks. See what digital MRV looks like for carbon projects in India, browse the projects we support, or talk to the team if you are scoping a project and want to know what evidence it will need.

What should you take away from CCTS?

The move to a low-carbon economy takes more than ambitious targets: it takes systems that turn climate action into measurable, verifiable and accountable results. CCTS is a substantial step towards building that system in India, and the organisations best placed to participate will be those that understand the whole lifecycle — methodology selection, baseline assessment, MRV, verification and issuance — rather than only the trading at the end of it.

Flora Carbon AI does not treat carbon markets as a credit-trading mechanism alone. The more useful framing is that a carbon market is an evidence market: it links carbon science, technology and data to real-world climate action, and the next phase of India's carbon market is less about generating credits than about generating credible climate impact.
