India’s greenhouse gas framework pushes industries towards tailored decarbonisation targets

India’s new greenhouse gas emission intensity framework marks a significant step in turning climate ambition into enforceable industrial policy. The rules, which sit within the country’s carbon credit trading architecture, are designed to support India’s wider Paris Agreement commitments, including a 47 per cent reduction in emissions intensity of GDP by 2030 and net-zero by 2070.

The first phase of the scheme is now aimed at nearly 490 industrial units across some of the economy’s most carbon-intensive sectors, including cement, aluminium, chlor-alkali, pulp and paper, petroleum refining, petrochemicals, textiles and secondary aluminium, according to government material. Earlier notifications focused on a smaller group of high-emitting sectors, but the compliance net has since widened as the policy has moved beyond design and into implementation.

At the heart of the framework is a simple but consequential idea: firms will be judged on greenhouse gas emissions per unit of output. That makes the policy more flexible than an absolute cap, but it also creates a more complicated challenge for regulators and industry alike. Not every sector can cut emissions at the same speed or at the same cost, and not every plant starts from the same technical baseline.

That matters because industrial decarbonisation is rarely uniform. In cement, part of the emissions profile comes from the chemistry of clinker production, while in aluminium the carbon burden is closely tied to electricity use. In refining, petrochemicals and textiles, process complexity, fuel choice and equipment efficiency can vary sharply from site to site. As a result, what looks like a modest target on paper may be inexpensive for one company and expensive for another.

This unevenness is not a flaw in the policy so much as a reflection of industrial reality. The government has set different targets across sectors, and in some cases across product types, precisely because a one-size-fits-all approach would have ignored the differences in abatement potential and operational constraints. Cement plants, for example, face reductions in the range of 4.7 per cent to 7.6 per cent over the compliance period, while some pulp and paper units may face cuts of as much as 15 per cent. Aluminium and chlor-alkali are expected to make steadier, more moderate gains.

The more difficult issue is that even within a single sector, the cost of avoiding an extra tonne of emissions can differ widely. Facilities with newer equipment, better fuel access, stronger logistics or more efficient heat recovery systems will generally find compliance easier than older plants with legacy infrastructure. That makes the distribution of costs as important as the national target itself.

For that reason, the measurement backbone of the system will be just as important as the target-setting exercise. Credible monitoring, reporting and verification is essential if the market for carbon credits is to function with confidence. Without reliable baselines and transparent emissions data, the trading mechanism risks becoming administratively heavy while delivering limited climate value.

The broader policy question is how India manages the transition from target-setting to actual industrial transformation. Supportive measures will be crucial for sectors and plants facing higher abatement costs, particularly where capital requirements are large and technology upgrades are slow to pay back. Financing, technical assistance and clearer decarbonisation pathways could help reduce the burden on firms that are structurally disadvantaged.

There is also a strategic case for phased expansion. As the framework matures, further coverage will likely need careful calibration, especially if sectors such as iron and steel are brought in later. The success of the system will depend not only on how ambitious the targets are, but on whether they are aligned with technology readiness, investment cycles and the practical realities of industrial operations.

India has now moved beyond announcing intent. The harder task is to make the mechanism work fairly, with enough market depth, institutional credibility and policy support to turn emissions intensity targets into real-world reductions.
