Supply Chain Decarbonisation Through Carbon Credits – A Guide for Indian Companies Managing Scope 3 Emissions

Introduction: The Hidden Carbon in Your Supply Chain

Every company has a carbon footprint. But for most companies, the largest part of that footprint is invisible—hidden in the supply chain.

For a typical company, Scope 3 emissions—emissions from the supply chain, business travel, employee commuting, and product use—can account for 80-90% of total emissions. For many sectors, the proportion is even higher.

The numbers are stark. India's steel and aluminium exports to the European Union fell 24.4 percent in Financial Year (FY) 2025, with steel alone down 35.1 percent, before any Carbon Border Adjustment Mechanism (CBAM) financial obligation had taken effect. The decline suggests European buyers are already reorienting toward lower-emission producers—not just for their direct operations but across their entire supply chains.

As one analysis notes, "A large part of carbon risk will not sit within a company's own operations, but within its supply chain. Many businesses, which currently view carbon only from the lens of compliance, may discover that their exposure comes indirectly through suppliers, financing relationships, and export dependencies rather than from emissions alone."

This guide examines the role of carbon credits in supply chain decarbonisation, how Indian companies can manage Scope 3 emissions, and what businesses must do to prepare for a future where supply chain carbon performance determines market access.

The CBAM Connection: Scope 3 and Export Competitiveness

What Is CBAM?

The Carbon Border Adjustment Mechanism is the EU's carbon tariff on imports. It came into effect on January 1, 2026.

The Scope 3 Connection

CBAM currently covers Scope 1 and Scope 2 emissions for covered sectors. However, there is growing discussion about expanding CBAM to include Scope 3 emissions in the future.

The Impact on Indian Exporters

Impact	Description
Direct Impact	CBAM costs for Scope 1 and 2 emissions
Indirect Impact	Suppliers with high emissions may be excluded
Competitive Pressure	European buyers favour lower-emission suppliers
Supply Chain Reorientation	Buyers shifting to lower-emission producers

The India-EU FTA CBAM Annexure

The India-EU FTA includes provisions for engagement on carbon border measures, including:

• Product scope and embedded emissions coverage
• Monitoring, reporting and verification processes
• The possibility to take into account the carbon price effectively paid

The Strategic Imperative

For Indian exporters, managing Scope 3 emissions is not just about compliance—it is about maintaining market access in carbon-constrained markets.

The CCTS Connection: How Domestic Carbon Compliance Supports Scope 3 Reduction

The CCTS Framework

The Carbon Credit Trading Scheme (CCTS) covers Scope 1 emissions for obligated entities. This creates a direct incentive for suppliers to reduce their emissions.

The Supply Chain Effect

Effect	Description
Supplier Compliance	Suppliers reduce emissions to meet CCTS targets
Cost Pass-Through	Carbon costs are passed through the supply chain
Competitive Advantage	Low-carbon suppliers gain advantage
Data Availability	CCTS data provides supplier emissions data

The Offset Mechanism

The CCTS offset mechanism allows companies to purchase carbon credits to offset their emissions, including Scope 3 emissions.

The Domestic Carbon Price

India's domestic carbon price creates a price signal that:

• Encourages suppliers to reduce emissions
• Makes low-carbon products more competitive
• Provides a basis for carbon cost pass-through

The ICM Portal

The Indian Carbon Market Portal provides data on:

• Entity emissions
• Carbon credit transactions
• Compliance status

The Role of Carbon Credits in Scope 3 Management

The Carbon Credit Hierarchy

Priority	Approach	Description
1	Reduce	Reduce emissions within your operations
2	Influence	Encourage suppliers to reduce emissions
3	Offset	Purchase carbon credits for residual emissions

The Abatement vs. Offset Debate

As Shuchi Malhotra, lead advisor for carbon markets at the Environmental Defense Fund, emphasised: "Carbon credits are a complement to your overall decarbonization journey. They are not a substitute."

When to Use Carbon Credits

Scenario	Use of Carbon Credits
Residual Emissions	Offset emissions that cannot be reduced
Transition Period	Bridge to future reductions
Supplier Emissions	Offset supplier emissions
Product Emissions	Offset emissions from specific products

What to Look For in Carbon Credits

Factor	Why It Matters
Additionality	The credit represents real, additional reductions
Permanence	The reduction is long-lasting
Verification	The credit is independently verified
Registry	The credit is on a recognised registry
CCP Label	The credit meets ICVCM Core Carbon Principles

---

The Quality Imperative: Buying the Right Credits

The ICVCM Core Carbon Principles

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

The 10 Principles

Category	Principles
Governance	Effective governance, tracking and transparency, independent third-party validation and verification, robust methodology development
Emissions Impact	Additionality, permanence, robust quantification, no double counting
Sustainable Development	Sustainable development benefits and safeguards, contribution to net-zero

The Quality Checklist

Factor	What to Look For
Registry	Verra, Gold Standard, or CR-I
CCP Label	Does the credit carry the CCP label?
Additionality	Clear evidence of additionality
Permanence	Buffer pools, insurance, long-term monitoring
Quantification	Clear methodology, third-party verification
Co-benefits	SDG contributions, biodiversity protection, community benefits

The Price Premium for Quality

CCP-labelled credits maintain a significant premium over non-CCP credits. This premium reflects the market's recognition of the higher quality and integrity of CCP-labelled credits.

The Reputation Risk

Buying low-quality credits is a reputational and financial risk. Companies that purchase credits without due diligence face:

• Greenwashing accusations
• Reputational damage
• Potential regulatory action
• Wasted investment

The MSME Challenge: Addressing Supplier Emissions

The Scale of the Challenge

India's supply chain is dominated by MSMEs. These small and medium enterprises often lack:

• Carbon accounting capabilities
• Verification capacity
• Financial resources
• Technical expertise

The MSME Data Gap

Problem	Description
No Emissions Data	MSMEs often do not measure emissions
No Verification	MSMEs cannot afford third-party verification
No Digital Systems	Lack of carbon accounting software
No Technical Expertise	Cannot calculate embedded emissions

The Default Values Trap

If suppliers cannot provide actual emissions data, buyers must use default values provided by the European Commission. These default values are set at the highest benchmarks and can sharply inflate carbon costs.

Supporting MSME Suppliers

Action	Description
Capacity Building	Train suppliers on carbon accounting
Technology Support	Provide access to digital MRV tools
Financial Support	Help suppliers finance decarbonisation
Collaborative Projects	Work together on emissions reduction

The Government's Response

The Commerce Ministry is rolling out a nationwide district-level outreach initiative to help MSMEs adapt to the EU CBAM. This includes:

• District-level workshops
• Digital engagement tools
• Carbon mapping support
• Verification preparation

Pitfall 2: Poor Data Quality

Problem: Using inaccurate or incomplete supplier data.

Solution: Implement robust data collection and verification processes.

Pitfall 3: Greenwashing

Problem: Making misleading claims about carbon neutrality.

Solution: Be transparent. Use high-quality, verified credits.

Pitfall 4: Buying Low-Quality Credits

Problem: Purchasing credits that don't represent real reductions.

Solution: Conduct rigorous due diligence. Buy CCP-labelled credits.

Pitfall 5: Not Engaging Suppliers

Problem: Not working with suppliers to reduce emissions.

Solution: Engage suppliers early. Provide training and support.

Pitfall 6: Underestimating Costs

Problem: Not budgeting for Scope 3 management.

Solution: Develop a comprehensive budget. Explore financing options.
