CCTS Readiness & PAT Transition Consulting for Indian Industries

Preparing Obligated Entities for India's New Carbon Market

As of April 1, 2025, India's industrial compliance landscape has fundamentally changed. The Carbon Credit Trading Scheme (CCTS), notified under the Energy Conservation (Amendment) Act, 2022, has replaced the Perform, Achieve and Trade (PAT) scheme as the primary regulatory instrument for energy-intensive industries. For approximately 461 obligated entities across 9 sectors, the era of measuring compliance in tonnes of oil equivalent has ended. Compliance is now measured in tonnes of COâ‚‚ equivalent per unit of product output — and verification is conducted by Accredited Carbon Verification Agencies (ACVAs), not traditional energy auditors.

SARK Engineers & Consultants helps Indian industries prepare for this transition. Building on 70+ completed PAT-scheme audits and 20 years of BEE-aligned MRV discipline, we specialize in CCTS readiness consulting: the technical, documentation, and data-system preparation that obligated entities need before their first ACVA verification.

Who Must Comply with CCTS?

If your facility is in any of the following sectors and was previously a PAT Designated Consumer, you are almost certainly an obligated entity under CCTS:

Sectors with targets already notified (compliance in force):

  • Aluminum (notified October 2025)

  • Cement (notified October 2025)

  • Chlor-Alkali (notified October 2025)

  • Pulp & Paper (notified October 2025)

  • Petroleum Refining (notified January 2026)

  • Petrochemicals (notified January 2026)

  • Textiles (notified January 2026)

Sectors with targets pending notification:

  • Iron & Steel

  • Fertilizer

Coal-fired power generation is expected to be added in a subsequent phase. Once all nine initial sectors are notified, approximately 740 entities will hold legally binding GHG emission intensity targets.

Frequently Asked Questions — CCTS Readiness

​

Q1. What is CCTS and how is it different from PAT?

The Carbon Credit Trading Scheme is India's first compliance-based carbon market, notified under the Energy Conservation (Amendment) Act, 2022. It replaces the Perform, Achieve and Trade (PAT) scheme for energy-intensive industries by changing the compliance metric from energy consumption (TOE) to greenhouse gas emission intensity (tCOâ‚‚e per unit of product). The trading instrument is the Carbon Credit Certificate (CCC) instead of the Energy Saving Certificate (ESCert). Verification is conducted by Accredited Carbon Verification Agencies (ACVAs) instead of BEE-empanelled energy auditors.

​

Q2. Which sectors are currently under CCTS compliance obligations?

As of January 2026, seven sectors have notified greenhouse gas emission intensity targets and are in active compliance: aluminium, cement, chlor-alkali, pulp & paper, petroleum refining, petrochemicals, and textiles. Two remaining sectors from the first nine — iron & steel, and fertilizer — are awaiting target notification. Approximately 461 obligated entities are currently covered.

​

Q3. How do I know if my facility is an obligated entity under CCTS?

Obligated entities are notified by the Ministry of Environment, Forest and Climate Change (MoEFCC) through the Greenhouse Gas Emission Intensity Target Rules, 2025. If your facility was a PAT Designated Consumer in one of the nine transitioning sectors, you are almost certainly an obligated entity. SARK Engineers offers a complimentary applicability review to confirm your status and identify your specific baseline and target.

​

Q4. What is an Accredited Carbon Verification Agency (ACVA)?

An ACVA is an organization accredited by the Bureau of Energy Efficiency to conduct validation and verification under CCTS. Accreditation follows ISO 14065 competency requirements and is mandatory before a verification body can formally verify GHG inventories, emission intensity calculations, or project-level emission reductions for CCC issuance. ACVA accreditation is organizational — it is distinct from individual auditor certification. As of early 2026, BEE is processing Round 2 of ACVA accreditation applications.

​

Q5. Can SARK Engineers verify my facility for CCC issuance?

No. CCTS verification for CCC issuance must be conducted by an independent, BEE-accredited ACVA. Independence requirements specifically exclude the consulting firm that prepared the facility for verification. SARK Engineers acts as your readiness and preparation partner — we ensure your facility is verification-ready, and an independent ACVA then performs the formal verification. This separation is a deliberate feature of the CCTS architecture, modelled on international best practice under the EU ETS and other compliance carbon markets.

​

Q6. What is the compliance year for CCTS?

The first CCTS compliance year started on April 1, 2025. Targets are set in three-year windows with annual reporting. The baseline year for most notified sectors is FY 2023-24. Entities must submit annual emission intensity data, undergo ACVA verification, and surrender Carbon Credit Certificates equivalent to any shortfall against target.

​

Q7. What happens if my facility misses its CCTS target?

An entity that fails to meet its annual target must purchase Carbon Credit Certificates equivalent to the shortfall from over-performing entities through the Indian Carbon Market. If the entity cannot obtain sufficient CCCs or fails to surrender them, penalties apply under the Environment (Protection) Act, 1986 and the Greenhouse Gas Emission Intensity Target Rules, 2025. Failure to maintain proper MRV documentation can independently trigger non-conformity findings during ACVA verification, delaying CCC issuance or resulting in adverse verification conclusions.

​

Q8. Can over-achievement on CCTS targets generate tradable credits?

Yes. Obligated entities that reduce their emission intensity below their notified target earn Carbon Credit Certificates equivalent to the over-performance. These CCCs are tradable on Indian power exchanges under CERC oversight. First CCC trading is expected to commence by mid-2026. Each CCC represents one tonne of COâ‚‚ equivalent reduction.

​

Q9. How is GHG emission intensity calculated for my sector?

Emission intensity is calculated as tonnes of COâ‚‚ equivalent per unit of product output, with sector-specific numerator and denominator definitions set by BEE and notified in the Greenhouse Gas Emission Intensity Target Rules, 2025. For example, cement intensity is expressed per tonne of cementitious product, aluminium intensity per tonne of liquid aluminium, and pulp & paper intensity per tonne of product at the sub-sector level. Scope 1 and Scope 2 emissions are both included. Sub-sector disaggregation is often required for multi-product facilities.

​

Q10. Can my existing PAT records be reused for CCTS compliance?

Partially. Your PAT records provide a strong foundation for CCTS compliance because they already include energy consumption data, production records, and plant boundary definitions. However, PAT data must be converted into GHG emission intensity metrics using appropriate emission factors, process emissions must be added (especially for cement, steel, aluminium, and fertilizer), and the documentation must be restructured to match ACVA evidence expectations. A PAT-to-CCTS transition audit is typically the fastest path to CCTS readiness for facilities with mature PAT records.

​

Q11. How long does CCTS readiness preparation take?

A typical engagement for a medium-sized obligated entity preparing for its first CCTS verification takes 10-14 weeks: 1-2 weeks for applicability and boundary setting, 3-4 weeks for GHG inventory development, 2-3 weeks for MRV system design, 2-3 weeks for emission intensity calculation and gap analysis, and 1-2 weeks for mock verification and readiness review. Integrated multi-plant facilities or facilities with significant data gaps may require longer engagements.

​

Q12. Is CCTS linked to CBAM or international carbon markets?

CCTS is an independent domestic compliance market. However, international alignment is a stated policy objective. The BEE has clarified that ACVA accreditation follows ISO 14065, and CCTS evidence standards align with ISO 14064 series — both of which are internationally recognized. Facilities exporting to the European Union should note that CCTS compliance does not automatically satisfy CBAM (Carbon Border Adjustment Mechanism) reporting obligations, which have separate requirements, but strong CCTS documentation significantly reduces the incremental burden of CBAM compliance.
