India's Carbon Market Goes Live: Inside the Carbon Credit Trading Scheme

Part 3 of a 5-part series on India's Sustainability and Climate Change Laws

For decades, Indian environmental regulation worked on a simple, blunt logic: pollute beyond a permitted limit, and face a penalty. That command-and-control model is now being layered with something far more sophisticated - a market that lets companies buy, sell and bank the right to emit, with real money riding on environmental performance.

The legal foundation for this shift is the Energy Conservation (Amendment) Act, 2022, which created the architecture for India's Carbon Credit Trading Scheme, or CCTS, and the broader Indian Carbon Market it sits within. What was once a regulatory abstraction is now, as of 2026, an operating reality for hundreds of Indian companies.

How the Compliance Mechanism Actually Works

The CCTS replaces the older Perform, Achieve and Trade scheme, which measured energy efficiency, with a system that measures actual greenhouse gas emissions intensity - tonnes of CO2 equivalent per unit of output. Companies in designated energy-intensive sectors are assigned legally binding emission intensity targets. Beat your target, and you earn tradeable Carbon Credit Certificates that can be sold on India's power exchanges. Miss it, and you must buy and surrender an equivalent number of certificates to make up the shortfall.

This is no longer theoretical. Compliance obligations are already in force for roughly 490 entities across seven energy-intensive sectors - aluminium, cement, chlor-alkali, pulp and paper, petroleum refining, petrochemicals and textiles - covering the compliance years 2025-26 and 2026-27, with FY2023-24 data used as the baseline. Once targets for the remaining sectors, including iron and steel, are finalised, close to 740 entities are expected to fall under the scheme, placing India among the largest emissions trading systems anywhere in the world. The first actual trading of compliance-based credits is expected by the second half of 2026, regulated by the Central Electricity Regulatory Commission and administered by the Bureau of Energy Efficiency, with the Grid Controller of India operating the registry.

Crucially, non-compliance is not a cheap option. Entities that fail to surrender enough certificates face a penalty calculated at twice the average certificate price - a structure designed to make buying credits always the more rational choice, ensuring the scheme has real economic teeth rather than functioning as a paperwork exercise.

The Offset Mechanism: A Second, Voluntary Track

Running alongside the compliance mechanism is a voluntary offset mechanism, open to entities that fall outside the mandatory scheme. Renewable energy developers, agroforestry projects, waste-to-energy operators and even individual farmers can register qualifying emissions-reduction projects to generate certificates of their own, which can then be sold either to obligated companies needing to top up compliance or to voluntary corporate buyers chasing net-zero pledges. Several methodologies covering biogas, hydrogen and forestry projects have already been notified, with dozens of entities registering projects in the scheme's early months.

The Legal Questions Nobody Had to Answer Before

What makes this genuinely new legal territory is the nature of the asset being created. A carbon credit is intangible property whose value comes entirely from verified environmental performance, not physical production - and Indian law has had to catch up fast. Who owns the carbon rights generated by a multi-stakeholder renewable project? Can those rights be separated from the underlying land title? How should environmental attributes be allocated contractually among project partners to prevent the same reduction being counted twice? What indemnity structures protect a buyer if a project later fails verification?

These are not hypothetical questions for law firms working in this space - they are the daily substance of carbon emission reduction purchase agreements, project documentation, and registry dispute resolution. Without legal certainty on ownership, transfer and verification, a market like this simply cannot function. In that sense, lawyers in this field are not just regulating the Indian Carbon Market; they are actively building it, transaction by transaction.

There is also a geopolitical urgency behind all this. As the next article in this series explains, a domestic carbon price is no longer just a climate policy choice for India - it has become a trade necessity, as Indian exporters confront a new European carbon border tax that took full effect at the start of 2026.
