Carbon Markets Need a Trust Rail: Why India Should Build Carbon DPI
India’s carbon market rests on confidence in a specific claim: that one tonne of carbon dioxide equivalent (CO₂e) reduced, avoided or removed is exactly what it says it is. Unlike a physical commodity that can be weighed at the point of sale, a carbon credit derives its value from the evidence chain behind it. Its credibility depends on whether buyers, regulators and financiers can trace the underlying data, methodology and verification that support the certificate.
India has already created the foundation for this market through the Carbon Credit Trading Scheme (CCTS). The next step is to build the digital evidence layer that makes carbon claims measurable, auditable, verifiable and financeable at national scale. This is the case for treating digital measurement, reporting and verification (dMRV) as part of India’s next Digital Public Infrastructure (DPI) frontier: Carbon Digital Public Infrastructure (Carbon DPI).
CCTS provides the foundation; trust will determine the market
CCTS gives India the legal, institutional and market architecture for carbon trading. It identifies the administrator, registry, verifiers, trading regulator, obligated entities, non-obligated entities and the tradable instrument: the Carbon Credit Certificate (CCC). It also builds on India’s earlier experience with the Perform, Achieve and Trade (PAT) scheme, which familiarised Indian industry with target-based compliance, performance measurement and tradable certificates.
This means India does not need to design a carbon market from scratch. The institutional spine already exists. The next challenge is to ensure that the evidence flowing through this architecture is consistent, traceable and trusted. A CCC is credible only when the claim behind it can be followed from plant-level data to approved calculation logic, independent verification and registry issuance.
Manual measurement, reporting and verification (MRV) can support early compliance, but a large, multi-sector carbon market requires a more durable trust architecture. Plant data often sits across meters, spreadsheets, enterprise resource planning (ERP) systems, supervisory control and data acquisition (SCADA) systems, laboratory records and production logs. When this information is compiled retrospectively, verification becomes document-heavy and errors are discovered late.
dMRV strengthens the foundation already created by CCTS. It does not replace the regulatory architecture; it makes that architecture executable at scale. Once common data standards, calculation logic, audit trails and verification-ready evidence packs are created, the same infrastructure can support more plants, sectors, verifiers and compliance cycles.
Core insight
CCTS gives India the market architecture. Carbon DPI gives it the evidence layer needed to make every CCC traceable, auditable and financeable.
Why the DPI model fits carbon
India has used DPI to solve trust problems before. The Unified Payments Interface (UPI) created a common public rail for payments. The Open Network for Digital Commerce (ONDC) applies similar logic to commerce by enabling interoperable discovery and transactions across platforms. Carbon markets present the same structural challenge: many participants, scattered data, high trust requirements and a need for standardised exchange.
Carbon DPI would not mean that the state operates every carbon service. It would mean that the public layer defines the common standards, application programming interfaces (APIs), calculation logic, verification rules and governance protocols. Private providers can still build measurement tools, analytics platforms, compliance dashboards, verification services and finance products. The public layer stays thin; the market builds above and below it.
DPI analogy
UPI: ₹1 must move as ₹1.
ONDC: one order must be discoverable and executable across the network.
Carbon DPI: one tonne CO₂e must be measured, verified and traceable.
Why this is technically feasible across sectors
Industrial sectors differ in fuels, processes, materials and production outputs. Yet the carbon accounting logic underneath them is more common than it first appears. Across sectors such as cement, aluminium, iron and steel, fertiliser, refineries, petrochemicals, textiles, chlor-alkali, and pulp and paper, emissions accounting follows a shared sequence: capture industrial activity data, calculate combustion, process and indirect emissions, aggregate total greenhouse gas emissions, and normalise performance into Greenhouse Gas Emission Intensity (GEI).
This common carbon accounting spine makes digital implementation feasible. Sector-specific modules can apply Bureau of Energy Efficiency (BEE)-aligned methodology logic while still using a shared architecture for data capture, validation, audit trails and verification-ready evidence.
Why this is technically feasible
CCTS sectors are operationally different, but they share a common carbon accounting spine: industrial data, emissions calculation, verification evidence and GEI.
What needs to happen next
India should build Carbon DPI while CCTS is still taking shape. Early design choices will determine whether the market grows around fragmented reporting practices or shared digital standards. The implementation path is clear: standardise sector data schemas, digitise BEE-aligned calculation modules, create verification-ready evidence packs, link plant systems to verifiers and the registry through common APIs, and preserve a thin public standard layer that enables private innovation.
The strategic opportunity is significant. A digital-native carbon market can reduce compliance friction, improve buyer confidence, support climate finance and help Indian industry prove carbon performance in export markets. It can also help India avoid the transition costs faced by older carbon markets that are now modernising manual legacy systems.
