India’s Carbon Credit Trading Scheme: What Obligated Entities Need to Know in 2026

India’s Carbon Credit Trading Scheme (CCTS) represents the most consequential shift in the country’s climate governance architecture since the Energy Conservation Act was amended in 2022. With the Bureau of Energy Efficiency (BEE) now deep into the operationalisation process, the window for obligated entities to prepare is narrowing faster than most boardrooms appreciate. This article sets out what designated consumers and potential participants need to understand — and what they should be doing right now.

The Notification That Changed Everything: 28 June 2023

On 28 June 2023, the Ministry of Environment, Forest and Climate Change (MoEFCC) notified the Carbon Credit Trading Scheme, 2023 under Section 12 of the Energy Conservation (Amendment) Act, 2022. This was not a policy paper or a discussion document. It was a legally binding notification in the Gazette of India, establishing the framework for a compliance carbon market that will eventually cover a significant share of India’s industrial greenhouse gas emissions.

The notification established several foundational elements:

  • A National Steering Committee chaired by the Secretary, MoEFCC, responsible for overall governance, target-setting, and international linkage decisions.
  • BEE as the Administrator, tasked with developing the detailed rules, registry infrastructure, MRV protocols, and day-to-day market operations.
  • The Indian Carbon Market (ICM) as the umbrella construct, comprising both a compliance mechanism and a voluntary offset mechanism.
  • Carbon Credit Certificates (CCCs) as the tradeable unit, each representing one tonne of carbon dioxide equivalent (tCO2e) reduced or removed.

The notification also made clear that the existing Perform, Achieve and Trade (PAT) scheme — which deals in energy savings certificates (ESCerts) denominated in tonnes of oil equivalent — would eventually transition into the CCTS framework. This is not a replacement; it is an evolution from energy efficiency to GHG intensity as the compliance metric.

BEE’s Progress: What Has Been Done So Far

Since the notification, BEE has been working through a systematic operationalisation process. As of early 2026, the following milestones are either completed or in advanced stages:

  • Technical committees have been constituted for each major sector to develop GHG intensity benchmarks. These committees include industry representatives, academic experts, and officials from line ministries.
  • Draft methodologies for GHG accounting at the installation level have been circulated to industry associations, drawing heavily on ISO 14064-1 and the GHG Protocol Corporate Standard.
  • The registry architecture is being developed in collaboration with the Grid Controller of India (formerly POSOCO) and CRISIL, building on the existing REC registry infrastructure but with significant enhancements for GHG tracking.
  • Stakeholder consultations have been held across multiple rounds, with sector-specific workshops for cement, iron and steel, aluminium, fertilisers, and thermal power.
  • International engagement with the EU, Singapore, and Japan on potential linkage frameworks and mutual recognition of carbon credits — a process that has accelerated following the EU CBAM’s definitive period commencing in January 2026.

What BEE has not yet done is finalise the sector-specific benchmarks or announce the first compliance period start date. This is the source of considerable uncertainty — and the reason why many obligated entities are delaying preparation, which is a strategic error we will address below.

The 13 Designated Consumer Sectors and Thresholds

The Energy Conservation Act identifies designated consumers across 13 sectors. Under CCTS, these sectors form the initial compliance universe:

  • Thermal power plants (generation capacity threshold: 30 MW and above)
  • Iron and steel (production capacity threshold: approximately 30,000 tonnes per annum)
  • Cement (production capacity threshold: approximately 30,000 tonnes per annum)
  • Aluminium (smelter capacity thresholds as specified under PAT)
  • Fertilisers (all major urea, DAP, and complex fertiliser plants)
  • Textiles (energy consumption threshold-based)
  • Pulp and paper
  • Petrochemicals
  • Chlor-alkali
  • Railways (traction energy consumption)
  • Petroleum refineries
  • Commercial buildings (connected load or contract demand thresholds)
  • Discoms (distribution companies, for demand-side management obligations)

The exact thresholds for CCTS participation have not been finalised, but BEE has signalled that the initial coverage will broadly mirror the PAT scheme’s designated consumer list — approximately 1,000 to 1,200 industrial units across these sectors. Over time, the scheme is expected to expand to additional sectors and lower thresholds, potentially covering 2,000+ entities.

The PAT-to-CCTS Transition: What Changes

The transition from PAT to CCTS is not merely a relabelling exercise. It involves fundamental changes in the compliance metric, the accounting methodology, and the market dynamics:

From Energy Intensity to GHG Intensity

PAT measures performance in specific energy consumption (SEC) — energy consumed per unit of production, denominated in tonnes of oil equivalent per tonne of product. CCTS will measure performance in GHG intensity — tonnes of CO2 equivalent per unit of production or per unit of economic output. This means that fuel mix, process emissions, and electricity grid emission factors all become relevant, not just energy efficiency.

From ESCerts to CCCs

ESCerts (1 ESCert = 1 tonne of oil equivalent saved) will give way to Carbon Credit Certificates (1 CCC = 1 tCO2e reduced). The conversion methodology between the two is still being developed, but it will need to account for the emission factor of the energy saved — a megawatt-hour of coal-fired electricity saved has a different GHG value than a megawatt-hour of gas-fired electricity saved.

Scope Expansion

PAT focuses primarily on energy consumption at the plant boundary. CCTS is expected to cover at minimum Scope 1 (direct emissions from owned/controlled sources) and Scope 2 (indirect emissions from purchased electricity), with the possibility of limited Scope 3 coverage for specific sectors in later phases. Process emissions — such as the calcination of limestone in cement or the reduction of alumina in aluminium smelting — will be fully included, which PAT does not directly capture.

Timeline

The PAT scheme is currently in its seventh cycle (PAT VII). BEE has indicated that the transition to CCTS will be phased, with the most emissions-intensive sectors (thermal power, iron and steel, cement, aluminium) moving first, likely in the 2026-2028 timeframe. Other sectors may continue under a modified PAT framework until CCTS benchmarks are ready. The exact transition schedule remains subject to the finalisation of sector benchmarks and the National Steering Committee’s approval.

GHG Intensity Benchmarking: How It Will Work

The benchmarking methodology is the heart of the compliance mechanism. Based on BEE’s consultations and the international precedents India is drawing on, the expected approach is:

  • Baseline establishment: Each designated consumer will need to establish a verified GHG intensity baseline for a reference period (likely 2-3 years of historical data). This requires installation-level GHG inventories following a standardised methodology.
  • Sector-specific benchmarks: BEE’s technical committees will set sector benchmarks based on statistical analysis of the reported intensities — likely using a percentile approach (e.g., the sector average, the top quartile, or a declining trajectory).
  • Compliance targets: Each designated consumer will receive an intensity reduction target relative to their baseline or the sector benchmark, to be achieved over a compliance period (expected to be 3 years initially).
  • Overachievement generates CCCs: Entities that reduce their GHG intensity below their target can sell surplus reductions as CCCs on the exchange.
  • Underachievement requires purchase or penalty: Entities that fail to meet their target must purchase CCCs from the market or face financial penalties.

This is broadly similar to the EU ETS benchmarking approach but adapted for India’s industrial structure and data availability. The key difference is that India is starting with intensity-based targets (emissions per unit of output) rather than absolute caps (total emissions), which allows for industrial growth while still driving decarbonisation per unit of production.

What Designated Consumers Should Be Doing Right Now

The single biggest mistake we see across Indian industry is waiting for the final rules before starting preparation. The rationale — “why invest in systems before we know exactly what’s required?” — is understandable but dangerously short-sighted. Here is why, and what should be happening today:

1. Establish Installation-Level GHG Inventories

Regardless of the final benchmarking methodology, every designated consumer will need a verified GHG inventory at the installation level. This is not the same as the energy audits you have been doing under PAT. A GHG inventory requires:

  • Identification of all emission sources (combustion, process, fugitive, and mobile sources)
  • Activity data collection systems (fuel consumption, production volumes, electricity purchases, raw material inputs)
  • Application of appropriate emission factors (IPCC default, national, or installation-specific)
  • Uncertainty assessment and quality control procedures
  • Documentation sufficient for third-party verification

If you are starting from scratch, building a robust GHG inventory system takes 6-12 months. Starting now means you will have at least one full year of verified data before the first compliance period begins.

2. Build MRV Systems Aligned with ISO 14064

The Measurement, Reporting and Verification (MRV) architecture that BEE is developing draws heavily on ISO 14064 (Parts 1, 2 and 3). Organisations should be:

  • Implementing data collection systems that meet ISO 14064-1 requirements for organisational-level GHG quantification
  • Establishing internal quality assurance/quality control (QA/QC) protocols for emissions data
  • Training plant-level personnel on GHG accounting principles — this is a different skill set from energy management
  • Engaging accredited verification bodies to conduct trial verifications of their GHG inventories, identifying gaps before compliance reporting begins

The MRV system is not just about compliance. It is the foundation for identifying decarbonisation opportunities, benchmarking against peers, and building the data infrastructure needed for BRSR disclosures, CBAM reporting, and voluntary ESG ratings.

3. Model Your GHG Intensity Trajectory

Using your current GHG inventory data, model your intensity trajectory under different scenarios:

  • What is your current GHG intensity (tCO2e per tonne of product or per unit of revenue)?
  • Where do you sit relative to the sector average? (BEE has published some indicative data through its PAT reporting.)
  • What reduction is achievable through operational efficiency alone?
  • What capital investment would be needed to achieve 10%, 20%, or 30% intensity reductions?
  • At what carbon price does each abatement option become economically viable?

This marginal abatement cost analysis will determine whether you are a buyer or seller in the carbon market — and by how much. Entities that do this analysis now will be able to make informed capital allocation decisions rather than scrambling to buy credits at the last minute.

4. Assess Your CBAM Exposure

If you export to the European Union, the CCTS-CBAM nexus is critical. The EU’s Carbon Border Adjustment Mechanism reduces the CBAM duty by the amount of effective carbon price paid in the country of origin. If India’s CCTS results in a meaningful carbon price, your CBAM liability could be significantly reduced. Understanding your CCTS position and your CBAM exposure together is essential for strategic planning. (We cover CBAM in detail in our companion article.)

5. Engage with the Policy Process

BEE’s stakeholder consultations are ongoing. Industry associations — CII, FICCI, and sector-specific bodies — are coordinating responses. Entities that engage constructively with the benchmark-setting process are more likely to see benchmarks that reflect operational realities rather than theoretical ideals.

The Expected First Compliance Period

Based on BEE’s published timelines and the pace of stakeholder consultations, the most likely scenario for the first compliance period is:

  • 2026-2027: Finalisation of sector benchmarks and MRV protocols; mandatory baseline data submission by designated consumers in priority sectors (thermal power, iron and steel, cement, aluminium).
  • 2027-2028: First compliance period begins, likely as a “learning period” with reduced stringency targets and administrative penalties rather than punitive financial consequences.
  • 2028-2030: Full compliance period with trading on the designated exchange, market-determined CCC prices, and escalating penalties for non-compliance.

This timeline could accelerate if international pressure (particularly from the EU CBAM) creates urgency, or slow down if data quality issues prove more challenging than expected. Either way, the preparation timeline for industry is the same: start now.

Penalties for Non-Compliance

The Energy Conservation (Amendment) Act, 2022 provides for penalties that are significantly more severe than the original Act:

  • Failure to comply with GHG emission norms: Penalty of up to Rs 10 lakh, with an additional penalty of up to Rs 10,000 for every day of continued non-compliance.
  • Failure to furnish information or returns: Penalty of up to Rs 5 lakh.
  • Obstruction of inspections: Fine and potential imprisonment.

Beyond statutory penalties, the real cost of non-compliance will be market-driven. If an entity needs to purchase CCCs to meet its target and delays until the end of the compliance period, it will face elevated market prices as other short entities compete for limited supply. Early movers who invest in abatement or accumulate surplus credits will have a structural cost advantage.

There is also the reputational dimension. India’s BRSR framework requires listed companies to disclose their environmental performance, and SEBI is increasingly attentive to the quality of these disclosures. A CCTS non-compliance event will be visible to investors, rating agencies, and customers — particularly international customers who are themselves under supply chain decarbonisation pressure.

The Voluntary Offset Mechanism

The CCTS notification also establishes a framework for a voluntary offset mechanism, under which non-obligated entities can generate CCCs through verified emission reduction projects. This is India’s answer to the voluntary carbon market, but with sovereign oversight and quality assurance:

  • Eligible project types are expected to include renewable energy, energy efficiency, methane capture, afforestation/reforestation, and potentially carbon capture.
  • Methodologies will be developed by BEE, drawing on international standards (CDM, Gold Standard, Verra VCS) but adapted for Indian conditions.
  • Credits generated under the voluntary mechanism may be usable for compliance purposes, subject to quantitative limits and quality criteria.

This creates opportunities for project developers, renewable energy companies, and entities that can generate verified emission reductions outside the compliance perimeter. However, the quality bar is expected to be high — there is no appetite within the policy establishment for a repeat of the CDM-era controversies around additionality and environmental integrity.

International Linkage: The Bigger Picture

India has been cautious but strategic about international carbon market linkage. The CCTS notification empowers the National Steering Committee to explore bilateral and multilateral linkage arrangements, and discussions are underway with several jurisdictions:

  • EU ETS: Full linkage is distant, but mutual recognition of carbon credits for CBAM purposes is a near-term priority.
  • Singapore: The International Carbon Credit (ICC) framework provides a potential pathway for bilateral credit transfers.
  • Article 6 of the Paris Agreement: India is actively participating in Article 6.2 (bilateral cooperative approaches) and Article 6.4 (the successor to the CDM) negotiations, which will determine the framework for international carbon credit transfers.

For obligated entities, the practical implication is that CCTS compliance may eventually be achievable through a combination of domestic abatement, domestic credit purchases, and international credit purchases — but the rules governing international credits will be restrictive, and domestic abatement will always be the most strategically sound approach.

Building Your CCTS Readiness Roadmap

Based on our work with designated consumers across multiple sectors, we recommend a six-phase readiness approach:

  • Phase 1 (Months 1-3): GHG inventory gap assessment — compare your current data infrastructure against ISO 14064-1 requirements and BEE’s draft MRV protocols.
  • Phase 2 (Months 3-6): System build — implement data collection, calculation, and documentation systems for installation-level GHG accounting.
  • Phase 3 (Months 6-9): Baseline establishment — complete at least one full reporting cycle and engage a verification body for an independent assurance engagement.
  • Phase 4 (Months 9-12): Strategic analysis — model your intensity trajectory, benchmark against sector peers, develop a marginal abatement cost curve, and assess your likely position as a buyer or seller.
  • Phase 5 (Ongoing): Policy tracking and engagement — monitor BEE announcements, participate in consultations, and adapt your strategy as the rules are finalised.
  • Phase 6 (Compliance period): Active market participation — trade CCCs, optimise your abatement-vs-purchase strategy, and integrate carbon costs into operational decision-making.
