Regional spotlight: Carbon markets & offsets integrity in India — what's different and why it matters

India issued more than 35 million carbon credits between 2012 and 2025 under the Clean Development Mechanism and voluntary standards combined, making it the world's second-largest credit origination country after China. Yet in 2025, the average price of an Indian carbon credit traded at $3.80 per tonne of CO2e on voluntary markets, roughly one-third the global voluntary market average and less than one-tenth the price of European compliance allowances. This pricing disconnect reflects not a lack of abatement potential but a confluence of regulatory transition, integrity concerns, and market fragmentation that investors must understand before deploying capital into one of the world's most consequential emerging carbon markets.

Why It Matters

India's carbon market trajectory carries outsized global significance for three reasons. First, the country is the world's third-largest greenhouse gas emitter, responsible for approximately 3.9 billion tonnes of CO2e annually, representing 7.5% of global emissions. The government's updated Nationally Determined Contribution (NDC) commits to reducing emissions intensity of GDP by 45% below 2005 levels by 2030 and achieving net zero by 2070. Achieving these targets requires mobilizing an estimated $10.1 trillion in climate finance through 2070 according to the Council on Energy, Environment and Water (CEEW), with carbon markets positioned as a primary capital mobilization mechanism.

Second, India is building a compliance carbon market from scratch. The Energy Conservation (Amendment) Act of 2022 empowered the Bureau of Energy Efficiency (BEE) to establish the Indian Carbon Market (ICM), comprising both a compliance mechanism for obligated entities and an offset mechanism for voluntary participants. The Carbon Credit Trading Scheme (CCTS) notification issued by the Ministry of Power in June 2023, with detailed implementation rules finalized in 2024, creates a cap-and-trade system targeting 800+ industrial facilities across 13 sectors including thermal power, iron and steel, cement, petrochemicals, and aluminum. When fully operational, the ICM will cover approximately 40% of India's industrial emissions, making it one of the largest compliance markets globally by emission coverage.

Third, India's carbon market design choices will influence other emerging economies. Nations across Southeast Asia, Africa, and Latin America are watching India's approach to integrating voluntary and compliance mechanisms, managing the transition from CDM-era credit inventories, and balancing domestic climate ambition with industrial competitiveness. A credible Indian carbon market strengthens the global carbon pricing architecture; a poorly designed one risks undermining confidence across all emerging market carbon systems.

Key Concepts

Indian Carbon Market (ICM) is the domestic cap-and-trade system being established under the Energy Conservation (Amendment) Act, 2022. The ICM operates through Carbon Credit Certificates (CCCs) issued by the BEE, with trading conducted on designated power exchanges (the Indian Energy Exchange and Power Exchange India Limited). The compliance market sets sector-specific emission intensity benchmarks, with obligated entities required to surrender CCCs equivalent to any excess above their benchmarks. The offset mechanism allows non-obligated entities to generate CCCs through verified emission reduction projects, which can then be sold to compliance buyers.

Perform, Achieve, and Trade (PAT) is the existing energy efficiency trading scheme operated by BEE since 2012, which the ICM is designed to absorb and expand. PAT covers approximately 1,100 designated consumers across 13 sectors, issuing Energy Saving Certificates (ESCerts) for overachievement of energy intensity targets. Through six completed cycles, PAT has documented cumulative energy savings of 92 million tonnes of oil equivalent. The transition from PAT's energy-intensity metric to the ICM's emission-intensity metric represents a fundamental shift that expands coverage to process emissions and enables direct comparability with international carbon prices.

Voluntary Carbon Market (VCM) in India encompasses projects registered under international standards including Verra's Verified Carbon Standard (VCS), Gold Standard, and the American Carbon Registry, as well as India-specific mechanisms. India hosts approximately 1,800 registered VCM projects, dominated by renewable energy (52%), energy efficiency (18%), and waste management (12%) methodologies. The relationship between domestic compliance credits (CCCs) and international voluntary credits remains a critical policy question, with the government signaling that international transfers of Indian carbon credits will require corresponding adjustments under Article 6 of the Paris Agreement.

Article 6 of the Paris Agreement governs international carbon market mechanisms, with Article 6.2 establishing bilateral cooperative approaches and Article 6.4 creating a new international crediting mechanism supervised by the UN. India has signed bilateral agreements with Japan (under the Joint Crediting Mechanism), Switzerland, and Singapore for carbon credit transfers, but has maintained strategic ambiguity about broader Article 6 participation. The government's 2025 position paper indicates that India will prioritize domestic use of mitigation outcomes and apply corresponding adjustments only to credits explicitly authorized for international transfer, limiting supply to global markets and potentially supporting domestic price discovery.

What's Working

PAT Scheme Has Proven Domestic Cap-and-Trade Feasibility

India's experience with PAT provides a functional foundation that many countries launching compliance carbon markets lack. Over six cycles spanning 2012-2025, PAT demonstrated that Indian industrial facilities can accurately measure, report, and verify energy performance against benchmarks. The scheme's monitoring, reporting, and verification (MRV) architecture, operated through designated energy auditors accredited by BEE, has processed over 15,000 facility-level reports. ESCert trading volumes on the Indian Energy Exchange reached 18.2 million certificates in the sixth cycle, with prices stabilizing at INR 350-500 ($4.20-6.00) per certificate. While these prices remain low relative to the social cost of carbon, the trading infrastructure, regulatory capacity, and institutional familiarity established through PAT significantly de-risk the ICM's launch.

Renewable Energy Credits Demonstrate Scale

India's voluntary carbon market has generated substantial project development experience, particularly in renewable energy. The country's installed renewable energy capacity reached 203 GW by December 2025 (excluding large hydro), with solar and wind projects accounting for 82% of registered VCM project capacity. Major project developers including ReNew Energy Global, Adani Green Energy, and Tata Power Renewable Energy have built sophisticated carbon credit origination operations integrated with their power generation businesses. This supply-side maturity means the ICM can draw on a deep pool of experienced project developers, validators, and verifiers rather than building market infrastructure from zero.

BRSR and SEBI Disclosure Requirements Are Driving Corporate Demand

The Securities and Exchange Board of India's (SEBI) Business Responsibility and Sustainability Reporting (BRSR) framework, mandatory for the top 1,000 listed companies by market capitalization since fiscal year 2023, requires disclosure of Scope 1 and Scope 2 emissions with Scope 3 reporting on a comply-or-explain basis. SEBI's BRSR Core framework extends mandatory ESG assurance to the top 150 companies from fiscal year 2024. These requirements are creating sustained corporate demand for carbon accounting capabilities and, increasingly, for offset credits to address residual emissions. Indian conglomerates including Reliance Industries (committed to net zero by 2035), Tata Group (2045 target), and Mahindra Group (committed to carbon neutrality across operations) are establishing internal carbon pricing mechanisms ranging from $10 to $25 per tonne, signaling future compliance demand significantly above current VCM prices.

What's Not Working

Regulatory Uncertainty Stalls Investment

The ICM's implementation timeline has experienced repeated delays, undermining investor confidence. The CCTS was notified in June 2023 with Phase 1 originally expected to launch in 2024, but baseline determination, emission factor standardization, and allocation methodology finalization pushed operationalization into late 2025 and early 2026. As of February 2026, obligated entities have received provisional emission intensity benchmarks for only 7 of 13 targeted sectors. The absence of confirmed cap levels, allocation timelines, and penalty structures means that compliance buyers cannot make forward procurement decisions, project developers cannot project credit demand with confidence, and financial intermediaries cannot structure derivative products.

The relationship between the ICM and existing VCM credits adds further complexity. The government has not clarified whether existing VCS or Gold Standard credits from Indian projects will be eligible for compliance surrender under the ICM, creating stranded asset risk for holders of an estimated 120+ million vintage Indian credits. This ambiguity has depressed VCM credit prices from Indian projects, with some buyers discounting Indian credits by 30-50% relative to comparable projects in other jurisdictions.

Additionality Concerns Persist for Legacy Projects

India's carbon credit history carries significant integrity baggage. A 2024 analysis by Carbon Market Watch found that 68% of Indian CDM renewable energy credits issued between 2012 and 2020 would likely not meet current additionality standards, as many credited projects were commercially viable without carbon revenue and would have proceeded regardless. The International Council on Voluntary Carbon Markets (ICVCM) Core Carbon Principles assessment, which began evaluating methodology categories in 2024, is expected to exclude a substantial portion of legacy renewable energy methodologies, further eroding the value of Indian credit inventories.

More recent projects face scrutiny as well. Verra's updated methodology for grid-connected renewable energy (VM0038) tightened additionality requirements in 2024, requiring investment barrier analysis and common practice tests that eliminate projects receiving concessional finance or benefiting from India's Renewable Purchase Obligations. Project developers report that new renewable energy projects in India increasingly fail additionality screens, pushing credit generation toward more complex and expensive methodologies including methane avoidance, clean cooking, and nature-based solutions.

MRV Infrastructure Gaps Threaten Credibility

While PAT established baseline MRV capabilities, the ICM's expanded scope to cover process emissions (not just energy intensity) exposes significant gaps in monitoring infrastructure. Cement plants, steel mills, and petrochemical facilities require continuous emissions monitoring systems (CEMS) or rigorous periodic measurement protocols for process emissions including CO2 from clinker production, blast furnace operations, and catalytic cracking. A 2025 assessment by The Energy and Resources Institute (TERI) estimated that only 35% of facilities targeted under ICM Phase 1 have installed CEMS meeting international standards, with retrofit costs of INR 1.5-4 crore ($180,000-480,000) per facility creating compliance cost concerns, particularly for smaller operators.

Third-party verification capacity also requires expansion. India has approximately 45 BEE-accredited energy auditing firms, but the ICM's broader scope demands expertise in industrial process emissions, land-use change, and greenhouse gas quantification methodologies that extend beyond energy auditing. Building this capacity while maintaining verification quality is a multi-year undertaking that risks either bottlenecking project registration or compromising audit rigor.

What's Next

India's carbon market is approaching an inflection point. The operationalization of ICM Phase 1, expected to cover thermal power and potentially iron and steel sectors first, will establish the initial price signal for Indian compliance carbon. Market consensus estimates place early CCC prices in the range of $5-15 per tonne, significantly below European and developed-market levels but meaningfully above current VCM prices for Indian credits. As allocation tightens through subsequent phases and additional sectors enter the compliance market, prices are projected to reach $20-35 per tonne by 2030 according to the India Carbon Market Forecast by ICF International.

The resolution of Article 6 corresponding adjustment rules will determine whether India becomes a major exporter of high-integrity carbon credits or primarily channels mitigation outcomes toward domestic compliance. Early indications suggest a restrictive approach: the government's stated preference for domestic utilization, combined with ambitious NDC targets requiring substantial internal abatement, points toward limited international supply authorization. For international investors and compliance buyers accustomed to sourcing cheap Indian credits on voluntary markets, this shift could tighten supply and recalibrate pricing assumptions across the global carbon market.

FAQ

Q: When will the Indian Carbon Market become fully operational? A: The ICM is being implemented in phases. Phase 1, covering thermal power generation and likely iron and steel, is expected to begin compliance obligations in 2026, with benchmark years using 2023-2024 emission data. Full rollout across all 13 targeted sectors is projected for 2028-2030. Trading infrastructure on IEX is technically ready, but regulatory finalization of sector benchmarks, allocation methods, and penalty structures continues.

Q: Can international investors participate in the Indian carbon market? A: The current CCTS rules permit trading by obligated entities and registered offset project developers on Indian power exchanges. Foreign institutional investors may participate through registered entities but face capital account convertibility restrictions and SEBI regulations governing commodity derivative trading. The Reserve Bank of India has not yet issued specific guidance on carbon credit trading by foreign portfolio investors. Bilateral Article 6 agreements (with Japan, Switzerland, Singapore) provide alternative channels for international credit transfer.

Q: How do Indian carbon credit prices compare with global markets? A: Indian VCM credits traded at an average of $3.80 per tonne in 2025, compared to $7.50 global VCM average, $12-18 for CORSIA-eligible credits, and $65-85 for EU ETS allowances. The price discount reflects additionality concerns for legacy renewable energy credits, regulatory uncertainty about ICM eligibility, and oversupply from large CDM-era inventories. New issuances from higher-integrity methodologies (nature-based, methane avoidance, clean cooking) command premiums of 40-80% over legacy renewable energy credits.

Q: What are the biggest risks for carbon credit investors in India? A: Key risks include regulatory timeline uncertainty (ICM delays extending 12-18 months beyond announced schedules), credit eligibility risk (existing VCM credits potentially excluded from ICM compliance use), corresponding adjustment risk (government restricting international transferability), price risk (early ICM prices potentially lower than projections due to generous initial allocations), and MRV quality risk (verification standards evolving and potentially invalidating previously issued credits). Diversification across project types, vintages, and standards mitigates concentration risk.

Q: How does India's approach differ from China's national ETS? A: India's ICM and China's national ETS differ in several key dimensions. China launched with a single sector (power generation) and is gradually adding industries; India plans to launch with multiple sectors simultaneously. China uses absolute emission caps; India's initial design uses emission intensity benchmarks, allowing emissions to rise if production grows faster than efficiency improvements. China's ETS covers approximately 5 billion tonnes of CO2e (the world's largest by volume); India's ICM will initially cover approximately 1.5-2 billion tonnes. China's ETS prices averaged $10-12 per tonne in 2025; India's ICM prices are expected to start at $5-15 per tonne. Both markets face similar challenges with MRV infrastructure, data quality, and market liquidity.
