India launches its carbon credit market: what the world's largest emissions trading scheme means

India's Indian Carbon Market (ICM), built on the Energy Conservation (Amendment) Act 2022, formally launched its first compliance cycle in 2026. The scheme covers 800+ facilities in nine energy-intensive sectors: aluminium, cement, chemicals, fertilizers, iron and steel, oil refineries, petrochemicals, pulp and paper, and textiles. These sectors collectively account for roughly 40% of India's industrial greenhouse gas emissions. Each facility receives a carbon credit allocation (denominated in Indian Carbon Units — ICUs); those that emit less than their allocation can sell surplus credits; those that exceed it must buy. The Bureau of Energy Efficiency (BEE) runs the market. Voluntary carbon credits — separate from the compliance market — are also being standardised under the ICM framework, allowing forestry, clean cookstoves, and methane capture projects to generate tradable credits for export to global voluntary markets.

Three forces converged to push India toward a mandatory carbon market in 2026. First, international pressure: the EU's Carbon Border Adjustment Mechanism (CBAM), which takes full effect in 2026, will levy tariffs on Indian steel, aluminium, and chemicals exports unless India can demonstrate equivalent carbon pricing. Indian exports to the EU in these sectors exceed $8 billion per year. Second, domestic policy logic: the Perform, Achieve and Trade (PAT) scheme — India's earlier energy-intensity trading market — had successfully run five cycles and proven that market mechanisms could drive efficiency improvements in heavy industry without mandating specific technology choices. Third, climate credibility: India's 2070 net-zero pledge and 2030 NDC targets needed a credible domestic mechanism to demonstrate seriousness. A carbon market — even with lower prices than the EU ETS — signals to international investors and climate negotiators that India is institutionalising decarbonisation rather than relying on voluntary commitments alone.

800+: facilities covered in Phase 1. 40%: share of India's industrial GHG emissions covered. 9: sectors included in mandatory compliance. 4%: targeted annual emissions reduction per facility. ₹1,200-1,800: estimated trading price per ICU (one tonne of CO₂ equivalent) in the first year — lower than EU ETS (~€65/tonne) but enough to incentivise industrial investment in efficiency. 3 lakh crore rupees: estimated size of the carbon market by 2030 if Phase 2 includes power sector. 2.5 lakh: number of ESCerts traded under predecessor PAT scheme (2012-2022). 5: year duration of Phase 1 compliance cycle (2026-2030). $8 billion: India's EU exports in CBAM-covered sectors at risk without carbon pricing proof.

The ICM's effects ripple beyond corporate balance sheets. Steel and cement workers in carbon-intensive plants face an uncertain transition: facilities that cannot achieve emission reductions cheaply may delay capacity expansion or accelerate automation, affecting unionised workforces in states like Jharkhand, Odisha, and Chhattisgarh. Consumers will see modest cost pass-through: analysts estimate ICM compliance costs will add ₹200-400 per tonne to cement prices and ₹500-900 per tonne to steel — modest at the plant level but visible in construction costs. Rural and forest communities stand to benefit from voluntary carbon credits: NABARD estimates 5 lakh hectares of degraded forest land could generate ICUs through afforestation, channelling ₹3,000-5,000 crore per year to gram panchayats and tribal communities. The just transition risk is real: without explicit support for workers in high-emission facilities, carbon pricing could deepen regional inequality.

If Phase 1 (2026-2030) successfully drives 15-20% emissions intensity reductions in covered sectors, Phase 2 (2031-2035) is likely to expand to the power sector — India's largest emitter, at 1 Gt CO₂ per year. Including power in the carbon market would dramatically raise its ambition and price signal, but would require managing coal-dependent state discoms whose financial health is already fragile. International linkage is the other horizon: if ICUs are recognised under Article 6.2 of the Paris Agreement bilateral arrangements, Indian projects could sell credits to European and Japanese buyers at much higher prices than domestic trading, creating a massive incentive for green investment. The first bilateral Article 6 agreement — likely with Japan under its Joint Crediting Mechanism — is expected to be signed by 2027.

India faces a unique dilemma in global climate negotiations: it has pledged to peak emissions 'around 2040' and reach net zero by 2070 — the most distant timeline among major economies. But India's development compulsion is real: 240 million people still lack reliable electricity access, 45% of the workforce is in low-productivity agriculture, and the economy needs 7-8% growth for decades to close the per-capita gap with China. The carbon market is India's attempt to square this circle: put a price on carbon that nudges heavy industry toward efficiency and clean technology without mandating the level of emission cuts that would impose European-style costs on industries still catching up. The ICM is deliberately designed with lower carbon prices than the EU ETS, giving Indian industry a lower cost burden while still creating an incentive to invest in cleaner processes. Whether this calibrated approach can satisfy international climate ambition while protecting India's growth story will shape not just India's climate credibility — but the template for every rapidly industrialising nation trying to navigate the same long-term dilemma. The lesson here will matter far beyond India.
