India’s industrial sector emitted over one-fifth of national GHGs in 2022: manufacturing fuel use 13% and industrial processes/product use 9%, according to India’s First Biennial Transparency Report. The PAT scheme is transitioning into a market-based Carbon Credit Trading Scheme while many manufacturing sub‑sectors remain outside both frameworks.
Why this matters
Governance and policy
Industrial emissions shape India’s ability to meet nationally determined targets and the net‑zero by 2070 commitment. Policy choices determine regulatory burden, market signals, compliance capacity and international credibility.
Economic and energy security
Emission‑intensity targets affect manufacturing competitiveness, energy demand, capital flows and investment in low‑carbon technology. Carbon markets will create price signals, revenue streams and compliance costs for industries and power sector entities.
Environment and social impact
Industrial decarbonisation reduces local air pollution, occupational hazards and climate risk exposure for communities dependent on manufacturing and construction.
India’s industrial emissions: current profile
Industry accounted for over 20% of national emissions in 2022. Manufacturing fuel consumption contributed 13% and industrial processes and product use 9%. A large share of manufacturing and construction emissions is recorded as “non‑specific industries”.
PAT scheme: purpose, scope and limits
Purpose and mechanics
PAT targeted energy efficiency in a set of energy‑intensive industries, awarding Energy Savings Certificates (ESCerts) for verified improvements and allowing trading to meet targets.
Scope
- Original coverage: Thirteen energy‑intensive sectors (phased cycles).
- Remaining under PAT: Thermal power plants, railways, DISCOMs and commercial buildings.
Limitations
- Compliance gap: Non‑compliance rose between cycles, undermining effectiveness.
- Market frictions: Delays in ESCert issuance and trading reduced liquidity and enforcement reach.
- Focus: Energy efficiency metrics alone did not fully capture emissions from process CO2 or product‑use emissions.
Transition to Carbon Credit Trading Scheme (CCTS): rationale and design
Policy makers shifted from PAT to a performance‑based CCTS to move from energy‑efficiency targets to legally binding greenhouse‑gas emission‑intensity limits and an exchangeable carbon instrument.
Key features
- Target metric: Emission intensity (GHG per unit output) rather than only energy saved.
- Legal status: Binding GHG intensity targets for compliance years including 2025–26 and 2026–27.
- Market instrument: Carbon Credit Certificates (CCCs) tradeable on exchanges under CERC rules.
- Scale: Design covers nine industrial sectors and aims to create a domestic carbon market measured in hundreds of millions tCO2e.
CCTS implementation, scope and market mechanics
- Sectoral scope: Aluminium, cement, fertilisers, iron & steel, petrochemicals, petroleum refining, pulp & paper, textiles and chlor‑alkali.
- Compliance start: Obligations came into force for roughly 490 entities across seven energy‑intensive sectors from FY 2025–26; subsequent notifications extended targets to over 740 facilities.
- Market infrastructure: Indian Carbon Market Portal launched to administrate registration, issuance and transfer. CERC regulations define terms for purchase and sale of CCCs on power exchanges.
- Scale estimate: Independent estimates place potential coverage at about 477 million tCO2e for the initial market universe.
- Trading timeline: First public trading of CCCs anticipated imminently, subject to exchange operational readiness and registry settlement processes.
Institutional and regulatory framework
- Operational bodies: Power Ministry oversight, market portal operator, sectoral nodal agencies and registry operators for CCC issuance.
- Regulations: CERC regulations govern CCC trading on power exchanges and set contractual conditions for buyers and sellers.
- Compliance enforcement: Legally binding targets imply administrative penalties and market‑based settlement for shortfalls.
Policy gap: the “non‑specific industries” problem
Over 40% of manufacturing and construction emissions are recorded as “non‑specific industries” in the inventory. These are not disaggregated into clear sub‑sectors and therefore are outside PAT and CCTS mandates.
- Practical effect: A large emission share lacks sectoral targets, monitoring protocols and access to market mechanisms.
- Data shortfall: Aggregated reporting obscures fuel mix, process emissions and mitigation potential for many small and medium sub‑sectors.
Implications for India’s net‑zero objective
Excluding a substantial portion of manufacturing and construction emissions from calibrated policy instruments weakens the cumulative mitigation outcome and raises the cost of later corrective action. Effective pathway to net‑zero requires both upstream (heavy industry) and downstream (SME and construction) measures.
Challenges and policy options (way forward)
| Dimension | Challenge | Policy option |
|---|---|---|
| Data | Aggregated “non‑specific” coding; limited sub‑sector inventories | Mandate disaggregated reporting, national manufacturing energy surveys, facility‑level monitoring |
| Coverage | Large emission share outside market and targets | Phase expansion of CCTS/PAT to defined sub‑sectors; use threshold‑based inclusion |
| Market functioning | Liquidity, price formation and registry integrity | Streamline CCC issuance, ensure timely settlement, facilitate demand via public procurement of credits |
| Compliance & capacity | SMEs lack technical and financial capacity | Provide targeted finance, technical assistance, pooled crediting mechanisms and standardised baselines |
| Integrity | Risk of double counting and weak additionality tests | Robust MRV protocols, independent verification, linkages to national registry |
Comparison: PAT versus CCTS
| Dimension | PAT | CCTS |
|---|---|---|
| Primary metric | Energy savings (ESCerts) | GHG emission intensity (CCC) |
| Legal form | Targeted energy efficiency programme | Legally binding emission‑intensity obligations with tradable certificates |
| Coverage | Selected energy‑intensive sectors; some sectors remain | Nine industrial sectors plus phased inclusion; targets for >740 facilities |
| Market performance | ESCert delays, rising non‑compliance | Structured trading rules under CERC, registry and market portal |
| Enforcement | Administrative implementation with variable compliance | Binding GHG targets and market settlement mechanisms |
Model Questions
1. Examine the rationale behind India’s transition from the Perform, Achieve and Trade (PAT) scheme to the Carbon Credit Trading Scheme (CCTS). Discuss the key features and potential of the CCTS in achieving India’s industrial emission reduction targets. [GS-III: Economic Development]
The transition responds to PAT’s market and compliance weaknesses by shifting to emission‑intensity targets and tradable Carbon Credit Certificates (CCCs). CCTS sets legally binding GHG intensity limits, covers major sectors, establishes a registry and exchange trading under CERC rules, and mandates targets for hundreds of facilities. Potential lies in clear price signals, broader emission coverage and enforcement, but success depends on MRV integrity, market liquidity and inclusion of uncovered sub‑sectors.
2. Critically analyse the policy gap posed by “non‑specific industries” in India’s industrial climate strategy. What are the implications of this oversight for India’s net‑zero aspirations, and suggest measures to address it? [GS-III: Environment & DM]
“Non‑specific industries” account for over 40% of manufacturing and construction emissions but lack sub‑sectoral definition and mandates. The gap reduces aggregate mitigation, delays cost‑effective actions and raises future abatement costs, endangering net‑zero timelines. Remedies: disaggregate inventory data, adopt threshold‑based inclusion into CCTS/PAT, implement sectoral baselines, target SME finance and technical support, and strengthen facility‑level MRV to bring these emissions under regulation.
3. Elaborate on the institutional and regulatory framework underpinning India’s newly launched Carbon Credit Trading Scheme (CCTS). Discuss its significance as a governance mechanism for industrial decarbonisation. [GS-II: Governance]
CCTS operates with a national Carbon Market Portal, sectoral nodal agencies, CERC regulations governing CCC trades on power exchanges, and an emissions registry for issuance and retirement. It creates a compliance ecosystem combining legal targets, market instruments and administrative oversight. As governance mechanism it shifts regulation from voluntary measures to binding market‑based compliance, enabling enforceable reductions, transparent accounting and policy signals for investment in low‑carbon technologies.
4. Compare and contrast the Perform, Achieve and Trade (PAT) scheme with the Carbon Credit Trading Scheme (CCTS). How does the CCTS represent an evolution in India’s approach to industrial decarbonisation, and what challenges persist? [GS-III: Economic Development]
PAT focused on energy efficiency and ESCert trading; it faced issuance delays and rising non‑compliance. CCTS targets emission intensity with legally binding GHG limits and tradable CCCs, broader sectoral scope and formal exchange rules. Evolution includes performance‑based regulation, clearer enforcement and market architecture. Remaining challenges: bringing “non‑specific” emitters into scope, ensuring MRV integrity, market liquidity, SME capacity building and avoiding double counting of credits.
