India's Carbon Credit Trading Scheme and Pricing

A frequent trap in this cluster asks which body regulates trading of Carbon Credit Certificates, or quietly swaps a carbon tax for a cap-and-trade scheme in a statement question, betting that the aspirant has memorised the word "carbon" without the underlying economics. This chapter tests the market and institutional side of climate mitigation: how a country prices carbon, how it trades credits for cutting it, and how it banks carbon in living systems rather than in machinery.

Renewable Energy and Climate Mitigation Tech covers Carbon Capture, Utilisation and Storage (CCUS) technology and NITI Aayog's 2022 policy framework in depth, including the 750 MTPA target. This note covers carbon markets, carbon pricing economics, and natural sequestration instead, a different half of the same "carbon" umbrella.

India's Carbon Credit Trading Scheme

The Carbon Credit Trading Scheme (CCTS) was notified by the Ministry of Power on 28 June 2023, making it India's first mandatory domestic carbon market, officially termed the Indian Carbon Market (ICM). Its legal basis is Section 14AA, inserted into the Energy Conservation Act, 2001 by the Energy Conservation (Amendment) Act, 2022, which empowered the central government to specify a carbon credit trading scheme and designate an agency to issue certificates, each representing one tonne of CO2 equivalent reduced, avoided or removed.

The scheme runs on two tracks. The Compliance Mechanism is mandatory and evolved out of the older Perform, Achieve and Trade (PAT) scheme, itself run under the National Mission for Enhanced Energy Efficiency, one of the eight missions under the National Action Plan on Climate Change (2008). Under compliance, the government sets an entity-specific greenhouse gas emission-intensity target, in tonnes of CO2 equivalent per unit of output, for each obligated industrial unit. A unit that beats its target earns tradable Carbon Credit Certificates (CCCs); a unit that misses it must buy CCCs to cover the shortfall or pay a penalty. This is an important distinction from a classic cap-and-trade scheme: CCTS fixes an intensity target per unit of output, not an absolute ceiling on a sector's total emissions, a design that fits an economy still expanding its industrial base. The Offset Mechanism, added in December 2023, is voluntary, letting non-obligated entities register their own emission reduction, removal or avoidance projects and earn credits, a domestic alternative to international voluntary carbon markets.

Phase 1 of the compliance track covers seven energy-intensive sectors, aluminium, cement, chlor-alkali, pulp and paper, petroleum refining, petrochemicals and textiles, roughly 490 obligated entities transitioning off the PAT scheme, with iron and steel and fertiliser identified for a later phase. Institutionally, the National Steering Committee for the Indian Carbon Market (NSCICM), chaired by the Secretary, Ministry of Power, and co-chaired by the Ministry of Environment, Forest and Climate Change, oversees the scheme. The Bureau of Energy Efficiency (BEE) is the administrator; the Grid Controller of India operates the registry that issues and tracks CCCs; and the Central Electricity Regulatory Commission (CERC) regulates the actual trading of certificates.

CCTS did not invent this trading architecture, it inherited it. PAT, launched by BEE on 4 July 2012, already ran in three-year cycles and already let underperforming Designated Consumers buy their way to compliance, using Energy Saving Certificates (ESCerts), each equal to one tonne of oil equivalent of energy saved, traded weekly on the Indian Energy Exchange and Power Exchange India Limited, with CERC as regulator even then. CCTS keeps the power-exchange trading model and CERC's regulatory role but changes the underlying metric: ESCerts counted energy saved (in toe), CCCs count carbon reduced (in CO2 equivalent). A question that describes CCTS as India's "first" carbon credit trading platform, rather than the first to price carbon specifically, is glossing over this decade-long PAT lineage.

Carbon tax versus cap-and-trade

Economists group carbon pricing into two broad instruments. A carbon tax is a price instrument: the government fixes a price per tonne of CO2 emitted, and the resulting quantity of emissions cut is left uncertain, discovered only after firms respond to that price. A cap-and-trade scheme, or emissions trading system (ETS), is a quantity instrument: the government fixes a cap on total emissions, allocates or auctions tradable allowances within that cap, and lets the market discover the price of an allowance through trading. A tax gives price certainty and quantity uncertainty; cap-and-trade gives quantity certainty and price uncertainty. The European Union's ETS is the standard example of the second kind, built on a hard, declining cap.

India's own history shows the tax route being tried and then abandoned. The Clean Energy Cess, introduced by the Finance Act, 2010 as an excise duty on coal, lignite and peat, took effect from 1 July 2010 at Rs 50 per tonne, a de facto carbon tax on coal. It rose to Rs 100 per tonne in 2014-15, Rs 200 per tonne in 2015, and Rs 400 per tonne in 2016-17. It was abolished with the rollout of GST in July 2017, replaced by a GST Compensation Cess on coal at the same Rs 400 per tonne rate, but repurposed to compensate states for GST revenue loss rather than to fund clean energy. As part of the GST 2.0 reforms in September 2025, that Rs 400 per tonne cess on coal was itself withdrawn, with the GST rate on coal raised from 5% to 18% instead, so coal today carries no dedicated carbon-linked levy at all.

India therefore has no economy-wide carbon tax in force. Its principal domestic carbon-pricing instrument is the CCTS, and even that is not a textbook cap-and-trade scheme: it is an intensity-based baseline-and-credit system benchmarked to output, not an absolute cap on total sectoral emissions. A statement that calls CCTS "India's carbon tax" or "an absolute emissions cap" is testing exactly this distinction.

The choice is not accidental. An absolute cap freezes or shrinks a sector's total emissions regardless of how much it produces, which suits an economy whose industrial output is no longer growing fast. India's industrial base is still expanding, so an intensity target lets output grow while still rewarding whichever unit cuts CO2 per tonne of cement or aluminium fastest, an approach consistent with the government's repeated position that its mitigation obligations should track its stage of development rather than mirror a developed economy's absolute cap.

Natural and blue carbon sequestration

Beyond industrial capture, carbon is also drawn down and stored by living systems, a genuinely different mechanism from CCUS. India's updated Nationally Determined Contribution (2022) commits "to create an additional carbon sink of 2.5 to 3 billion tonnes of CO2 equivalent through additional forest and tree cover by 2030," delivered through afforestation, agroforestry and restoration of degraded and open forest land, and tracked periodically through the Forest Survey of India's State of Forest Report.

Soil organic carbon is a second pathway: agricultural soils store carbon in organic matter, and degraded or over-tilled soils release it back to the atmosphere as CO2, while practices such as reduced or zero tillage, crop residue retention, organic manure and agroforestry rebuild that stock instead of letting it oxidise away. Because this happens below ground, it does not show up in a forest-cover satellite survey the way afforestation does, which is precisely why exam questions treat it as a separate sequestration pathway from planting trees, even though both ultimately store carbon in organic matter. The global "4 per 1000" initiative, launched by France at COP21 in Paris on 1 December 2015, frames the scale of this pathway: it proposes that a 0.4% annual increase in the organic carbon stock of the world's agricultural soils, in the top 30 to 40 cm, could meaningfully offset humanity's net annual anthropogenic CO2 emissions. It is a voluntary international coalition of governments, research bodies and civil society, not a scheme with binding national targets.

Blue carbon refers to carbon captured and stored by coastal and marine ecosystems, specifically mangroves, seagrass meadows and salt marshes, the three ecosystems formally recognised as blue carbon ecosystems. These systems lock carbon into waterlogged, low-oxygen sediment, where it can stay buried for centuries, a different storage mechanism from a forest's above-ground biomass, and one reason coastal wetlands, mangrove and seagrass alike, are consistently found to sequester carbon several times faster per unit area than a mature tropical forest, even though they cover a far smaller global area. India's coastline supports all three. MISHTI, the Mangrove Initiative for Shoreline Habitats and Tangible Incomes, was announced in para 85 of the Union Budget 2023-24, following India's joining the Mangrove Alliance for Climate launched at COP27 in November 2022. Run by the Ministry of Environment, Forest and Climate Change, MISHTI targets restoring approximately 540 sq km of mangroves across nine coastal states and four Union Territories over five years (2023-2028), projecting around 22.8 million person-days of work and an estimated carbon sink of 4.5 million tonnes of carbon. It is implemented through convergence of the Compensatory Afforestation Fund Management and Planning Authority (CAMPA), which funds roughly 70% of the outlay, and MGNREGS, with technical support from the National Centre for Sustainable Coastal Management (NCSCM), Chennai.

Exam angle

This cluster is tested by swapping a name, a date or a mechanism for a similar-sounding one. CCTS, notified in June 2023, is easily confused with the National Green Hydrogen Mission, approved in January 2023, so anchor each scheme to its own notification month. CCTS is an intensity-based baseline-and-credit system, not a hard emissions cap, and it is not a tax, three separate claims a single option can get wrong at once. India's actual experiment with a carbon tax, the Clean Energy Cess on coal, ran from 2010 to 2017 and no longer exists in any form since the September 2025 GST reform, so a question describing India as currently levying "a carbon tax on coal" is out of date. Natural sequestration numbers are easy to conflate: the NDC's forestry sink target (2.5 to 3 billion tonnes of CO2 equivalent by 2030) is a different figure from the Panchamrit's separate one-billion-tonne cut in projected total emissions, and MISHTI's mangrove-specific 540 sq km target is not a general afforestation number. The "4 per 1000" initiative is a global, voluntary framework, not an Indian government scheme, a distinction UPSC likes to blur.

• India's NDC forestry target: additional carbon sink of 2.5 to 3 billion tonnes CO2 equivalent through forest and tree cover by 2030.
• "4 per 1000" initiative: France, COP21, 2015; 0.4% annual rise in agricultural soil organic carbon, a voluntary global coalition.
• Blue carbon ecosystems: mangroves, seagrass, salt marshes. MISHTI (Union Budget 2023-24): 540 sq km of mangrove restoration, 9 states and 4 UTs, 2023-2028, via CAMPA and MGNREGS convergence.

The three instruments in this note also nest inside one another. CCTS is how India prices carbon inside its own economy; the Clean Energy Cess-to-GST story is why it did not choose a tax to do so; and natural sequestration, forestry, soil and blue carbon together, is the sink side of the ledger that every emissions-cutting scheme is ultimately measured against on the way to net zero by 2070. A question naming any one of CCTS, the Clean Energy Cess or MISHTI in isolation is usually really asking whether the aspirant can place it correctly inside this larger carbon-management architecture.
