Priced Out: Carbon Credits and the Tier-2 Industrial Corridor Blind Spot
When India's next major industrial cluster enters the market, such as a Delhi Mumbai Industrial Corridor (DMIC) node in a Tier-2 city or a National Investment and Manufacturing Zone (NIMZ) in a mid-sized manufacturing district, it will enter a regulatory environment that has already decided, by design, that it does not quite belong. This is a consequence of the regulations and frameworks designed for cities with enterprise-grade auditing infrastructure, certified verifiers within driving distance, and the administrative bandwidth to run an annual carbon compliance cycle.
India now has a national carbon trading scheme in the form of the Carbon Credit Trading Scheme (CCTS). What it does not yet have is a version of that scheme that functions beyond the Tier-1 boardroom.
The Market Is Live. The Map Is Wrong.
India’s industrial decarbonisation officially entered its regulatory era with the notification of the CCTS, establishing a rate-based mechanism to price emissions across nine intensive sectors: aluminium, chlor alkali, cement, fertiliser, iron and steel, pulp and paper, petrochemicals, petroleum refinery, and textile.
However, a fundamental geographic mismatch exists between the system's design and its target landscape.
The architecture of the Indian carbon market assumes a baseline of enterprise-grade Monitoring, Reporting, and Verification (MRV), readily accessible third-party verifiers, and high institutional bandwidth, but these resources remain largely concentrated in Tier-1 cities. Meanwhile, industrial emissions are accelerating in Tier-2 nodes under the National Industrial Corridor Development Programme (NICDP). Without addressing this spatial divide, the market risks becoming a Tier-1 boardroom exercise rather than a transformative tool for India's emerging industrial heartlands.
How Tier-2 Remains Excluded
The current architecture excludes Tier-2 industrial corridors through three structural mismatches.
First, the Designated Consumer (DC) thresholds, such as 7,500 Tonnes of Oil Equivalent (TOE) for each of the industries of Aluminium and Pulp & Paper, inherited from the Perform, Achieve and Trade (PAT) scheme. These thresholds keep corridor-scale industries out by design, prioritising only the largest emitters.
Sector | Minimum annual energy consumption |
Aluminium | 7,500 TOE |
Cement | 30,000 TOE |
Cement Grinding | 10,000 TOE |
Chlor-alkali | 12,000 TOE |
Iron & Steel | 20,000 TOE |
Petrochemical | 1,00,000 TOE |
Petroleum Refining | 90,000 TOE |
Pulp & Paper | 7,500 TOE |
Textiles | 3,000 TOE |
Second, there is a severe MRV infrastructure gap. Participation requires annual monitoring of Scope 1 and 2 emissions, adherence to standardised templates, and the submission of performance assessment documents within four months of the financial year's end. Such reporting systems are rarely established in developing zones such as DMIC with its 24 investment nodes spread across six states, where administrative capacity is already stretched.
Third, a verifier desert exists outside Tier-1 hubs. Accredited Carbon Verification Agencies (ACVAs) must be empanelled by the Bureau of Energy Efficiency (BEE), yet existing technical institutions and energy auditors are heavily localised in Tier-1 centers. Out of a pool of 85 Accredited Energy Auditor (AEA) firms that BEE relies on, 30 are concentrated in Delhi NCR alone.
The PAT scheme serves as a cautionary precedent; it struggled with poor compliance enforcement and limited participation due to similar geographic and technical barriers. International parallels reinforce this concern: the China National ETS rollout was preceded by years of regional pilots in major cities to build sub-national capacity before a unified market could be operationalised. Even now, the Chinese system relies on a multi-level governance structure where municipal authorities manage covered entities directly, a layer of oversight that India’s corridor zones currently lack. Without replicating this phased, localised capacity-building, India’s market architecture will likely outrun the operational realities of its newest industrial clusters.
What CCTS Access Would Actually Look Like
Taking Nagpur’s Multi-modal International Cargo Hub and Airport (MIHAN) as a concrete illustration, CCTS participation reveals immediate operational hurdles.
For an industrial unit in the MIHAN Special Economic Zone (SEZ) to participate, it would need to perform rigorous annual GHG monitoring using standardised BEE templates. However, the institutional oversight for this is unclear. While the National Steering Committee oversees the national framework and BEE acts as the administrator, the specific roles of State Designated Agencies (SDAs) and State Pollution Control Boards (SPCBs) in enforcing corridor-level compliance are poorly defined. An industrial unit would be stranded between a central administrator in Delhi and a local authority with no clear carbon mandate.
The most visible gap is access to a BEE-accredited verifier. The system mandates that third-party agencies verify emissions reports to ensure market integrity. Yet, technical expertise for GHG validation remains largely clustered in Tier-1 education and research hubs. A unit in MIHAN would likely have to source specialised auditors from distant metropolitan centres, significantly increasing transaction costs and bureaucratic delays. This turns the abstract institutional argument into a traceable operational problem: a MIHAN-based industrialist is saddled with the Tier-1 compliance costs without the Tier-1 infrastructure. This isolation is further compounded by the lack of local testing centres and vocational training for carbon accounting, leaving corridor-scale units unable to build the internal capacity required for the CCTS's annual compliance cycle.
Building the Market Where the Emissions Are
To bridge this divide, policy must move beyond general climate laments, such as the broad net-zero commitments without implementation architecture, toward integrated market readiness. Sub-national carbon market readiness should be embedded as a core NICDP mandate, ensuring that "plug and play" infrastructure includes digital MRV backbones. Leveraging standardised baselines and aggregation methodologies, similar to those explored under international frameworks such as Article 6.4 under the Paris Agreement and the European Union Emissions Trading System (EU-ETS), could allow corridor-level units to pool their mitigation efforts. The BEE and carbon market authorities must also launch a targeted verifier development programme outside Tier-1 cities to decentralise the ACVA ecosystem.
With trading expected to launch by the end of this year, these architecture decisions must be made now; retrofitting these corridors later will prove costlier than building the market correctly from the outset.
India's carbon market ambition is real. The CCTS represents a genuine policy bet: that pricing emissions can drive industrial transformation at scale. But ambition and architecture are not the same thing. If the system continues to be built around the institutional geography of Tier-1 India, it will price the emissions it can most easily reach, not the ones that are growing fastest. The industrial corridors taking shape in Tier-2 cities are not peripheral to India's climate story but its next chapter. Getting the architecture right at this point is not optional, it is a necessity.
