The Institutional Infrastructure of Carbon Markets – Why Registries, Not Just Credits, Will Define India's Carbon Future

Introduction: The Quiet Transformation

For years, voluntary carbon markets have been judged on one question: Can carbon credits be trusted?

Questions around project quality, exaggerated climate claims, and inconsistent methodologies have dominated discussions among policymakers, businesses, and investors. New initiatives, including the Integrity Council for the Voluntary Carbon Market's (ICVCM) Core Carbon Principles and the Voluntary Carbon Markets Integrity Initiative (VCMI), have sought to establish higher standards for carbon credits and improve confidence in their use.

But while much of the attention has focused on the quality of carbon credits, another transformation has been unfolding quietly in the background. The institutions that record ownership, verify transactions, and prevent double counting are becoming just as critical to the future of carbon markets as the credits themselves.

A carbon registry performs a role similar to that of a securities depository in financial markets. It records when a carbon credit is issued, tracks every transfer of ownership, and confirms when a credit has been permanently retired. This creates a transparent and auditable record throughout the credit's lifecycle.

As India prepares to scale its own carbon market ecosystem and businesses increasingly integrate carbon markets into their decarbonisation strategies, understanding this shift is becoming a strategic business imperative.

India's Carbon Credit Trading Scheme (CCTS) is now in its operational phase. Compliance obligations are in force for approximately 490 entities across seven energy-intensive sectors, with the first compliance date on July 31, 2026. The Indian Carbon Market Portal was launched on March 21, 2026, serving as the central digital backbone of the Indian Carbon Market.

According to the World Bank's State and Trends of Carbon Pricing 2026 report, carbon markets continue to expand globally, supported by growing institutional participation and increasing demand for transparent governance frameworks.

This guide examines the institutional infrastructure of carbon markets—what registries are, why they matter, how they are evolving, and what this means for businesses participating in India's CCTS.

Credit Integrity vs. Market Integrity: A Critical Distinction

The distinction between credit integrity and market integrity is increasingly important.

Credit integrity asks whether a carbon credit genuinely represents one tonne of emissions reduced or removed. This is the question that has dominated carbon market discourse for years. It encompasses additionality, permanence, robust quantification, and third-party verification.

Market integrity asks whether participants can confidently buy, sell, finance, and retire those credits with complete transparency and reliable ownership records.

A carbon credit can be of the highest quality—real, additional, and permanent—but if the market infrastructure that tracks its ownership and prevents double counting is weak, the credit's value and credibility are undermined.

One cannot replace the other. A stronger registry cannot improve a weak carbon project, just as a stock exchange cannot improve the financial performance of a listed company.

However, efficient market infrastructure enables participants to transact with greater confidence, reduces operational risk, and improves transparency across the market.

This is the quiet transformation happening in carbon markets worldwide. The institutions that record ownership, verify transactions, and prevent double counting are becoming just as important as the credits themselves.

What Is a Carbon Registry? The Financial Market Analogy

A carbon registry performs a role similar to that of a securities depository in financial markets. It records when a carbon credit is issued, tracks every transfer of ownership, and confirms when a credit has been permanently retired. This creates a transparent and auditable record throughout the credit's lifecycle.

Key Registry Functions

Function	Description
Issuance Recording	Records when a carbon credit is created
Ownership Tracking	Tracks every transfer of ownership
Retirement Confirmation	Confirms when a credit has been permanently retired
Double Counting Prevention	Ensures each credit is only counted once
Serial Number Assignment	Assigns unique identifiers to each credit

The Financial Market Parallel

Financial Market	Carbon Market
Stock exchanges	Power exchanges (for trading)
Securities depositories	Carbon registries
Clearing houses	Registry verification systems
Market data providers	Carbon credit ratings agencies

Without trusted registries, even high-quality carbon credits face credibility challenges. Buyers cannot easily determine whether a credit has already been sold, transferred, or retired elsewhere, increasing the risk of double counting and reducing confidence in market transactions.

---

Why Registries Matter: Beyond Project Quality

The importance of robust tracking is increasingly recognised internationally. One of the ICVCM's Core Carbon Principles specifically requires carbon-crediting programmes to maintain secure registry systems capable of uniquely identifying and tracking every carbon credit throughout its lifecycle.

Why Registries Are Critical

Reason	Explanation
Prevent Double Counting	Without registries, the same credit could be sold multiple times
Enable Market Confidence	Buyers need assurance of ownership and retirement
Support Financing	Investors need reliable ownership records
Facilitate Compliance	Regulators need transparent tracking
Enable International Trading	Cross-border transfers require trusted registries

The Registry's Role in Market Trust

Registries do not determine whether a carbon project delivers genuine climate benefits—they determine whether the market itself can be trusted.

This is a critical distinction. A high-quality credit tracked through a weak registry loses value. A moderate-quality credit tracked through a robust registry retains credibility. The registry infrastructure is the foundation upon which market trust is built.

The Evolution: From Independent Standards to Institutional Infrastructure

For much of their history, voluntary carbon markets evolved through independent standards bodies such as Verra, Gold Standard, and others. These organisations developed methodologies, certified projects, and operated their own registries.

That model is beginning to change.

Verra's decision to modernise its registry in partnership with S&P Global Commodity Insights signals a broader evolution toward institutional-grade market infrastructure. Rather than operating registry systems independently, standards organisations are increasingly collaborating with companies experienced in commodity market infrastructure, market intelligence, and transaction systems.

The Evolution Timeline

Phase	Registry Model	Characteristics
Phase 1	Independent registries	Operated by standards bodies; limited integration
Phase 2	Collaborative registries	Partnerships with financial infrastructure providers
Phase 3	Institutional-grade registries	Integrated with financial markets; global interoperability

The Financial Market Parallel

This mirrors the evolution of traditional financial markets. Stock exchanges, custodians, clearing houses, and market data providers each perform specialised functions that collectively create confidence in financial transactions. Carbon markets have historically combined many of these responsibilities within standards organisations themselves. As participation grows, those roles are beginning to separate, reflecting the needs of a more mature marketplace.

The shift is not about replacing climate science with technology. Scientific debates around additionality, permanence, and project quality remain central to the credibility of carbon credits. Registry infrastructure simply addresses a different challenge—market integrity.

Verra and S&P Global: A Watershed Moment

Verra's decision to modernise its registry in partnership with S&P Global Commodity Insights is a watershed moment for carbon market infrastructure.

What This Means

Aspect	Implication
Institutional Integration	Carbon registries integrating with financial market infrastructure
Transparency	Enhanced tracking and reporting capabilities
Credibility	S&P Global's reputation for market data and infrastructure
Interoperability	Potential for cross-registry integration
Market Maturity	Carbon markets evolving toward financial market standards

The Significance for India

For India's CCTS, this evolution is directly relevant. The Indian Carbon Market Portal, launched in March 2026, represents India's own move toward institutional-grade carbon market infrastructure.

As India prepares to scale its own carbon market ecosystem, this shift could influence how businesses buy credits, finance climate projects, and participate in global carbon trading.

India's Registry Infrastructure: CR-I and the ICM Portal

Carbon Registry India (CR-I)

CR-I is India's first domestic carbon registry, established by the Network for Certification and Conservation of Forests (NCCF). It provides a platform for:

• Listing of GHG emission reduction projects
• Registration of eligible projects
• Verification of GHG emission reductions
• Issuance of Marketable Carbon Units (MCUs)

The Indian Carbon Market Portal

On 21 March 2026, Power Minister Manohar Lal Khattar launched the Indian Carbon Market Portal at the Prakriti 2026 International Conference on Carbon Markets in New Delhi.

The portal serves as the central digital backbone of the Indian Carbon Market, enabling end-to-end processes from entity registration to the issuance of Carbon Credit Certificates (CCCs), including validation, verification, and accreditation of third-party monitoring, reporting, and verification (MRV) bodies.

The platform is designed to serve both obligated and non-obligated entities and includes provisions for interacting with international carbon markets under Article 6 of the Paris Agreement, allowing project developers to register activities intended for cross-border crediting.

Registry Functions in India

Function	Responsible Entity
Carbon Registry	Carbon Registry India (CR-I) / Grid Controller of India
Trading Platform	Power Exchanges (IEX, PXIL, Hindustan Power Exchange)
Regulatory Oversight	Central Electricity Regulatory Commission (CERC)
Administration	Bureau of Energy Efficiency (BEE)

The ICVCM Core Carbon Principles and Registry Requirements

The Integrity Council for the Voluntary Carbon Market (ICVCM) has established the Core Carbon Principles (CCPs)—a global threshold for carbon credit quality.

Registry-Related CCP Requirements

One of the ICVCM's Core Carbon Principles specifically requires carbon-crediting programmes to maintain secure registry systems capable of uniquely identifying and tracking every carbon credit throughout its lifecycle.

Key Registry Requirements

Requirement	Description
Unique Identification	Every credit must have a unique serial number
Lifecycle Tracking	Credits must be tracked from issuance to retirement
Public Transparency	Registry data must be publicly accessible
Security	Registries must be secure against fraud and manipulation
Interoperability	Registries should enable cross-border transfers

What This Means for Indian Projects

For Indian carbon projects to achieve CCP labelling and access premium markets, they must be registered on registries that meet these requirements. CR-I is India's domestic registry, while Verra and Gold Standard are international options.

The Double Counting Problem and How Registries Solve It

What Is Double Counting?

Double counting occurs when the same emission reduction is claimed by multiple parties or used for multiple purposes. This can happen when:

• The same credit is sold to multiple buyers
• A credit is claimed for compliance and voluntary purposes
• A credit is counted towards multiple countries' NDCs

How Registries Prevent Double Counting

Mechanism	Description
Unique Serial Numbers	Each credit has a unique identifier
Transfer Tracking	Every transfer is recorded
Retirement Recording	Retired credits cannot be used again
Public Transparency	Anyone can verify credit status
Registry Reconciliation	Registries cross-check transfers

The India Context

Under the CCTS, the Grid Controller of India serves as the Registry, maintaining electronic accounts for all participants and ensuring that CCCs are not double counted. The ICM Portal provides the digital infrastructure for registry functions.

---

The Role of Registries in India's CCTS

The Three Pillars

India's carbon market operates through three key institutions:

Institution	Role
Bureau of Energy Efficiency (BEE)	Administrator—designs procedures, manages registration
Grid Controller of India	Registry—maintains electronic accounts, tracks CCCs
Central Electricity Regulatory Commission (CERC)	Regulator—sets price bands, oversees market operations

Registry Functions Under the CCTS

Function	Description
Account Management	Maintains electronic accounts for all participants
CCC Tracking	Tracks issuance, transfer, and holding of CCCs
Transaction Verification	Verifies and authenticates transfers
Ownership Recording	Records legal ownership of CCCs
Double Counting Prevention	Ensures transparency and accurate accounting

The ICM Registry

The ICM Registry, where registration and certificate management happen, is operated by Grid Controller of India. It serves as the central platform for CCC tracking and exchange.

For Investors and Financiers

Implication	Action Required
Due Diligence	Verify ownership and retirement through registries
Risk Assessment	Assess registry infrastructure as part of investment risk
Portfolio Management	Track carbon asset holdings through registries

The Four Implications for Indian Businesses

According to the World Bank's State and Trends of Carbon Pricing 2026 report, Indian businesses should expect several changes:

1. Greater transparency in carbon procurement - Companies purchasing carbon credits are likely to have access to richer project-level information, clearer transaction histories, and stronger evidence supporting retirement claims.

2. Higher expectations from investors and global customers - International investors increasingly expect companies to demonstrate not only that they purchase high-quality credits but also that those credits are transparently tracked and supported by robust governance systems.

3. Improved access to climate finance - Banks, insurers, and institutional investors are generally more comfortable participating in markets where ownership records are transparent and transactions are independently verifiable.

4. Greater interoperability across markets - As registry systems become more connected, businesses operating internationally may find it easier to navigate different standards, reducing fragmentation across voluntary carbon markets.

For sustainability leaders, carbon procurement is likely to evolve from an ESG reporting activity into a strategic business function that resembles financial risk management.

The CBAM Connection: Why Registries Matter for Exporters

The CBAM Requirement

Under the EU's Carbon Border Adjustment Mechanism (CBAM), importers must declare the embedded emissions of their imports. This requires verifiable, auditable emissions data.

How Registries Support CBAM Compliance

Registry Function	CBAM Relevance
Emissions Tracking	Verifiable emissions data for CBAM declarations
Carbon Price Evidence	Evidence of carbon prices paid domestically
Transparency	Publicly verifiable compliance data
Credibility	Official, government-backed registry

The India-EU FTA CBAM Annexure

The India-EU FTA includes a dedicated framework to address concerns surrounding the EU's Carbon Border Adjustment Mechanism, with safeguards aimed at easing compliance for Indian exporters, particularly small and medium enterprises.

The agreement contains a separate annexure on CBAM that lays out a comprehensive work plan to help India navigate the EU's carbon tax regime.

The annexure includes provisions covering verification processes, calculation of embedded carbon emissions, and engagement with EU authorities to ease compliance for smaller exporters.

A trusted registry infrastructure is essential for these provisions to function effectively.

The Future: Institutional-Grade Carbon Markets

The Trend Toward Institutional Infrastructure

For years, carbon market reform has focused on improving what is traded. The next phase will increasingly focus on improving how those trades are recorded, verified, and governed.

This evolution may receive less public attention than debates over carbon credit quality, but it could prove equally consequential.

The Implications for India

Trend	India Implication
Registry Modernisation	CR-I and the ICM Portal must evolve to meet global standards
Interoperability	Indian registries must connect with international registries
Transparency	Greater public access to registry data
Financial Integration	Integration with financial market infrastructure

The Long-Term Vision

Carbon credits will remain the foundation of voluntary carbon markets. Yet the institutions supporting those markets—registries, transaction platforms, and governance systems—may ultimately determine whether carbon markets mature into transparent, investable and globally trusted financial ecosystems.

Markets capable of attracting long-term institutional capital require trusted infrastructure as much as credible assets.

For Indian businesses preparing for the country's emerging carbon economy, the message is clear: the future of carbon markets will depend not only on buying better carbon credits, but also on participating in markets built on stronger institutions.
