India's Carbon Credit Trading Scheme (CCTS) is the country's first compliance carbon market — a mandatory, target-based mechanism built on the amended Energy Conservation Act, distinct from voluntary carbon credit markets and distinct from the older PAT (Perform, Achieve and Trade) energy-efficiency scheme it partly builds on.
How the mechanism works, structurally
CCTS designates obligated entities — initially concentrated in energy-intensive sectors such as aluminium, cement, iron and steel, and other large industrial emitters — and assigns each a greenhouse gas emissions intensity target (emissions per unit of output, not an absolute cap). Entities that beat their target generate Carbon Credit Certificates they can sell; entities that miss it must either improve operations or buy certificates to cover the shortfall. The Bureau of Energy Efficiency (BEE) administers the technical and target-setting side, with the Ministry of Environment, Forest and Climate Change (MoEFCC) providing the overarching regulatory framework, and the Central Electricity Regulatory Commission role in market oversight for the trading mechanism.
The intensity-based design — rather than an absolute cap — is a deliberate structural choice suited to an economy still growing industrial output, and it echoes the logic PAT already used for energy efficiency, now extended explicitly to GHG emissions rather than just energy consumption.
What "obligated" actually requires, in data terms
Before a target can even be assigned, an entity needs a defensible emissions intensity baseline — verified Scope 1 (and typically Scope 2, given purchased electricity is a major input for covered sectors) emissions, normalised against production output, for a defined baseline period. This is where most first-wave obligated entities discover gaps: production data and emissions data are frequently tracked in different systems, at different granularities, by different teams, and reconciling them into a single verifiable intensity figure is nontrivial the first time it's attempted.
The monitoring, reporting, and verification (MRV) requirements that follow are similar in spirit to CBAM's — facility-level data, defined emission factors, third-party verification — which means Indian exporters already building CBAM-grade MRV systems for EU-bound steel, aluminium, or cement are, in practice, building most of the same infrastructure CCTS compliance requires domestically.
Scope 3 relevance, even though the obligation is Scope 1/2
CCTS targets are set on direct and energy-related emissions, not the full Scope 3 inventory. But two Scope 3 connections matter in practice for obligated entities:
- Upstream input emissions increasingly show up in customer due diligence. As more of an obligated entity's customers — domestic and export — run their own Scope 3 supplier assessments, the intensity data generated for CCTS compliance becomes reusable evidence for exactly those customer requests, rather than a separate disclosure burden.
- Certificate trading itself becomes a Scope 3-adjacent decision. For entities considering purchasing carbon credit certificates to cover a shortfall, understanding where those reductions physically occur, and how they'll be treated in downstream customer inventories and disclosures, is becoming part of standard due diligence before a purchase — not an afterthought.
Where to start
For a first-wave obligated entity, the sequence that avoids scrambling later is: lock down a verifiable baseline emissions intensity figure now, build the facility-level MRV system to the standard third-party verification will require, and treat any parallel CBAM or BRSR reporting obligation as a shared data-infrastructure project rather than three separate compliance exercises running on three separate timelines.
