Greenhouse Gas Emission Intensity Target Rules

India's First Legally Binding Greenhouse Gas Emission Rules: A Step Forward or Half a Leap?

On October 11, 2025, the Central Pollution Control Board (CPCB) became the enforcement arm of India's first legally binding Greenhouse Gas Emission Intensity Target Rules, 2025. These rules aim to regulate the carbon footprint of 282 specific industrial units across four sectors—aluminium, cement, chlor-alkali, and pulp & paper—shaping India's long overdue domestic carbon market under the Carbon Credit Trading Scheme (CCTS), 2023. The announcement calibrated specific emission intensity targets measured in tonnes of carbon dioxide-equivalent per unit output (tCO₂e/unit), redefining how sectors historically resistant to regulation interact with climate commitments. A bold move, but is it enough?

Breaking From Past Patterns

India's earlier attempts at industrial decarbonisation relied on the Perform, Achieve, Trade (PAT) scheme. While PAT incentivized energy efficiency across designated consumers, it struggled to create a vibrant trading market. That was its Achilles’ heel: no functioning price signals, no liquid carbon market, and emissions intensity reductions were non-binding. The CCTS, 2023 overhauls this framework, tying compliance to market-based penalties and enforceable targets. In essence, it injected grit into a soft instrument. Unlike PAT, these new rules are tied to strict monitoring mechanisms through CPCB, which supplements its mandate with financial penalties and environmental compensation for non-compliance.

The shift to product-output intensity targets is another break from precedent. Sectoral baselines—designed for years 2025–26 and 2026–27—acknowledge the vast differences in emission benchmarks across industries. For instance, the aluminium sector, responsible for nearly 15 million tons of CO₂ annually, faces targets that explicitly account for its process-linked emissions. A one-size-fits-all approach would have been untenable given the scale and diversity of emissions profiles.

The Institutional Machinery Behind the Rules

At the heart of this new framework lies the Carbon Credit Trading Scheme (CCTS), operationalised under the Energy Conservation Act, 2001, amended in 2022. This grants the Bureau of Energy Efficiency (BEE) and CPCB the authority to oversee the issuance, verification, and endorsement of carbon credits. These credits, tradeable within the domestic market, are designed to prop up industries that exceed their compliance targets.

Penalties for non-compliance add teeth to the rules, but the efficacy of enforcement largely depends on India's capacity to deploy robust Measurement, Reporting, and Verification (MRV) systems. Without standardised protocols and credible audits, even legally binding targets risk becoming toothless paper decrees. Moreover, the Rules demand high coordination between industries and state pollution control boards—a known bottleneck in Indian environmental governance.

The Numbers: What the Data Tells Us

The optimism surrounding India's domestic carbon market has been bolstered by its Paris Agreement commitment to reduce emissions intensity of GDP by 45% by 2030 compared to 2005 levels. But ground realities temper the narrative. Consider this:

• India's industrial sector contributed to approximately 26% of total GHG emissions in 2020, with cement and aluminium ranking among the top polluters.
• The carbon credit market is estimated to generate trading opportunities worth ₹25,000 crore annually, assuming compliance targets are met.
• Despite these Rules applying to 282 units initially, industries under review collectively account for less than 13% of India’s industrial GHG emissions—a significant gap.

The implicit assumption is that incremental sectoral coverage will occur, but the timeline remains vague. Unlike China's National Emissions Trading Scheme, which targets absolute emissions in power plants as its initial phase, India’s focus on emission intensity sidesteps hard caps, reflecting a preference for incremental control over larger systemic transformation.

Uncomfortable Questions

The irony of the GEI Target Rules, 2025, lies in their framing as a "legally binding" mechanism. While CPCB penalties and compensatory norms give the Rules procedural heft, enforcement hinges on the genuine implementation of MRV systems—a weak link in India's climate governance. The experience with PAT showed that data verification was uneven, bureaucratic, and prone to manipulation.

Another question relates to market volatility: can India manage the price oscillations likely in a fledgling carbon market? Earlier PAT certificates suffered from poor uptake due to weak market liquidity; trading volume was modest, and price discovery mechanisms were dysfunctional. If this pattern repeats, the CCTS risks under-delivering on its economic promise to catalyse cleaner technology adoption.

The Rules also test institutional capacity to scale compliance beyond top-tier industries to smaller players, who often lack the resources for high-cost technology upgrades. ₹15,000 crore in transition financing through India's Green Climate Fund has been announced, but analysts question whether this allocation is sufficient to cover sector-wide transformation.

Comparative Anchor: Lessons from South Korea

The Korean Emissions Trading Scheme (K-ETS), operational since 2015, offers critical lessons. As Asia’s first mandatory cap-and-trade system, K-ETS began with electricity and heavy industries, expanding annually with stringent compliance rates. Key to its success was the integration of transparent MRV technologies, such as blockchain and automated reporting systems, ensuring credit integrity. India's GEI rules trail far behind in this regard, with MRV power still heavily reliant on manual protocols. South Korea’s early inclusion of technology subsidies also cushioned industrial adaptation costs—a strategy conspicuously absent in India’s rollout.
