Carbon Markets in India: CCTS, Offset Mechanism and Article 6 Explained

Quick Answer: India’s Carbon Credit Trading Scheme (CCTS), notified by the Ministry of Power on 28 June 2023 under the Energy Conservation (Amendment) Act 2022, is India’s first compliance carbon market framework. It creates tradeable Carbon Credit Certificates (CCCs), administered by the Bureau of Energy Efficiency (BEE) with trading regulated by the Central Electricity Regulatory Commission (CERC), and is designed to link with global markets under Article 6 of the Paris Agreement.

What is India’s Carbon Market? The Direct Answer

India’s carbon market is built around the Carbon Credit Trading Scheme India framework — a compliance-based cap-and-trade system that sets greenhouse gas emission intensity targets for energy-intensive industries and allows entities that outperform their targets to sell Carbon Credit Certificates to those that fall short. The scheme was notified in June 2023 and operationalised in a phased manner from 2024–25, with the BEE as scheme administrator and CERC as the trading regulator. It replaces and builds upon the older Perform, Achieve and Trade (PAT) scheme as India’s principal market-based climate instrument.

What is a Carbon Market? Cap-and-Trade vs Baseline-and-Credit

Carbon markets put a price on emissions so that pollution carries an economic cost. Two broad designs exist:

• Cap-and-trade (compliance market): A regulator sets an emissions cap or emission-intensity target. Entities below the target sell surplus allowances; those above must buy. Example: EU Emissions Trading System, and now India’s CCTS.
• Baseline-and-credit (voluntary market): A project that reduces emissions below a business-as-usual baseline (e.g., afforestation, renewable energy) earns credits sold to willing buyers — corporations seeking carbon neutrality. Example: Verified Carbon Standard projects.

Compliance markets are legally binding; voluntary markets depend on corporate demand. India’s offset mechanism under CCTS deliberately bridges the two.

Energy Conservation (Amendment) Act 2022: Legal Foundation of CCTS

The Energy Conservation (Amendment) Act, 2022 amended the Energy Conservation Act, 2001 to explicitly empower the central government to specify a carbon credit trading scheme. Key provisions include:

• Enabling the issuance of carbon credit certificates and their trading in a designated market.
• Empowering the government to set energy consumption norms that can be expressed as emission intensity targets.
• Authorising the Centre to specify a minimum share of non-fossil energy consumption for designated consumers (giving legal backing to renewable purchase obligations).
• Extending coverage to large residential and commercial buildings with a connected load above a prescribed threshold, supporting an energy conservation and sustainable building code.
• Widening the governing council of the BEE to include environmental and climate expertise.

Carbon Credit Trading Scheme (CCTS): How It Actually Works

Under the CCTS framework:

• BEE (under the Ministry of Power) acts as the scheme administrator — it finalises sectoral emission intensity targets, verifies compliance and issues Carbon Credit Certificates.
• CERC regulates the trading of certificates and carbon trading exchanges.
• Grid operators (POSOCO/Grid-India) are associated with the registry functions, ensuring accurate data on electricity use for intensity calculations.
• The compliance cycle works in phases: targets are notified for obligated entities (initially the energy-intensive designated consumers covered under PAT), entities report performance, verification follows, and certificates are issued. Over-performers sell CCCs; under-performers buy them to meet targets or face penalties under the Energy Conservation Act.

India announced the first compliance cycle targets for select sectors for 2025–26, moving from the older PAT cycles to emissions-intensity-based trajectories aligned with NDC goals.

The Offset Mechanism Under CCTS

The offset mechanism — notified in December 2023 and elaborated in subsequent amendments — allows non-obligated entities (those not bound by compliance targets) to voluntarily register emission-reduction projects and earn Carbon Credit Certificates. Key features:

• Open to entities such as renewable energy projects, afforestation, waste-management and energy-efficiency projects meeting approved methodologies.
• Projects must demonstrate additionality — reductions beyond what would occur anyway.
• The National Steering Committee for Indian Carbon Market (NSCICM) approves methodologies and oversees registration; the BEE manages the offset registry.
• Credits generated can be traded domestically, giving smaller green project developers a revenue stream and feeding market liquidity.

Article 6 of the Paris Agreement: The Global Linkage

Article 6 of the 2015 Paris Agreement sets the rules for international carbon cooperation (finalised in detail at COP26 Glasgow and refined at COP29 Baku). It has three arms:

• Article 6.2 — Bilateral cooperation: Countries trade Internationally Transferred Mitigation Outcomes (ITMOs) under bilateral agreements, requiring “corresponding adjustments” so the same tonne of carbon is not counted twice by seller and buyer.
• Article 6.4 — Centralised mechanism: A UN-supervised carbon crediting mechanism (successor to the Kyoto Protocol’s Clean Development Mechanism) with a registry, methodologies and sustainable development checks. Operational rules were largely finalised at COP29 (2024).
• Article 6.8 — Non-market approaches: Cooperation without trading, such as capacity building and joint climate finance initiatives.

India’s International Carbon Credit Strategy

India historically was the largest generator of CDM credits under the Kyoto Protocol, hosting thousands of registered projects. Post-Paris, India’s position has evolved:

• Domestic-first stance: India stated at COP27 (2022) that credits under CCTS would initially be used to meet the country’s own NDCs before being sold abroad.
• Corresponding adjustments: If credits are exported under Article 6.2 or 6.4, India must add the sold emissions back to its own inventory — a cost India weighs carefully while its NDCs remain demanding.
• CDM transition: India pushed for smooth transition of eligible CDM projects/activities to the Article 6.4 mechanism, though only a small fraction of global CDM projects sought transition by the 2025 deadline.
• India has been negotiating bilateral Article 6.2 agreements to eventually monetise surplus mitigation without compromising NDC achievement.

Challenges and Criticisms of India’s Carbon Market

• MRV gaps: Reliable measurement, reporting and verification infrastructure is still maturing; weak MRV risks credibility of credits.
• Overlap with existing schemes: Coexistence of PAT (energy efficiency), Renewable Purchase Obligations and CCTS creates complexity and potential double counting; the eventual subsuming of PAT into CCTS needs careful transition.
• Liquidity and pricing concerns: Thin early trading volumes could cause price volatility and weak price discovery.
• International linkage uncertainty: Rules on corresponding adjustments and Article 6 demand remain fluid, complicating long-term investor planning.
• Capacity constraints: Many designated consumers, especially MSME-linked units, lack technical capacity for intensity accounting.

Significance for Climate Goals: NDCs and Net Zero 2070

CCTS is central to India’s market-based decarbonisation pathway. India’s updated NDCs (2022) include reducing the emissions intensity of GDP by 45% from 2005 levels by 2030 and achieving about 50% cumulative electric power installed capacity from non-fossil sources by 2030, en route to net zero by 2070. By pricing carbon, CCTS channels private capital toward emission reductions, complements the green hydrogen mission and renewable build-out, and positions Indian industry for carbon border measures such as the EU’s CBAM.

Frequently Asked Questions

When was the Carbon Credit Trading Scheme notified in India?

The CCTS was notified by the Ministry of Power on 28 June 2023 under the Energy Conservation Act framework as amended in 2022. The offset mechanism framework followed in December 2023, with compliance targets for the first cycle notified subsequently.

What is the difference between compliance and voluntary carbon markets?

A compliance market (like CCTS) imposes legally binding emission caps or intensity targets on obligated entities. A voluntary market lets projects sell credits to willing buyers without legal obligation. India’s offset mechanism bridges both — non-obligated entities voluntarily generate credits that can flow into the compliance market.

Can Indian carbon credits be sold internationally under Article 6?

Eventually, yes. Under Article 6.2 (bilateral ITMOs) and 6.4 (centralised mechanism), credits can be exported, but sellers must make corresponding adjustments so the reduction is not double-counted. India’s stated stance is domestic-first — using CCTS credits for its own NDCs before authorising exports.

Is the CCTS relevant for UPSC Prelims or Mains?

Both. Prelims can test facts — notification date, parent Act, BEE/CERC roles, Article 6 provisions. Mains GS Paper 3 (environment and economy) and Essay can ask about carbon markets, climate governance and net-zero pathways.

How is CCTS different from the existing PAT scheme?

PAT trades energy-efficiency certificates (Escerts) based on specific energy consumption norms; CCTS trades carbon credits based on emission-intensity targets. Both operate under the Energy Conservation Act and are administered by BEE, but CCTS is broader and aligned with greenhouse-gas accounting and Article 6 linkages.
