Neeraj Akhoury, CEO India Holcim and Managing Director and CEO, Ambuja Cements, draws a clear path for sustainable shift towards blended cement, which would lead to lesser use of clinker, thereby enabling the industry to reach its decarbonisation targets.

In today’s world, cement stands shoulder to shoulder with core sectors like steel, energy and others as one of the key building blocks to nation building. With the current market size of $325 billion, the cement industry (in GDP terms) would rank among the top 50 industrialised nations in the world today. By 2028, this market is expected to grow to $460 billion. And when that happens, the global cement industry would have raced past another dozen or more countries in GDP terms.
Leaders in the cement sector across the world are not only aware of the opportunity this represents, but the weight of the responsibility that comes with it. Almost all major cement producers have committed themselves to a Net Zero future, an important decarbonisation movement that has also taken the larger industrial world by storm.

Planning Ahead
In the cement sector, we have identified every stage in the value chain as a potential target for decarbonisation. The execution of this change is happening within the bigger framework of ‘Circular Economy’. In simple terms, the principles of circular economy pushes manufacturers to treat every material (natural and processed) to be used in perpetuity. A key element in this system is the ability to cut down or reduce as one of the three Rs, along with reuse and recycling to achieve long term sustainability.
For the cement sector, one of the focus areas has been reduction of the use of clinkers in the manufacturing process, or what in industry parlance is called ‘clinker factor’. Clinker is an intermediary material used in the production of cement.
The reduction of clinker factor is achieved by replacing it with alternative blending materials like pozzolana, slag or fly ash (industrial waste) to produce blended cements. This reduces the carbon intensity of the cement—a primary lever for reduction of carbon emissions.
So, the more we shift towards blended cement, the lesser will be the use of clinker and thus move the cement industry closer to its ultimate decarbonisation targets.
The growing demand for blended cement in a country like India is particularly very effective in combating climate change. India is today the second-largest cement producer and consumer, with the share of blended cement of around 75 per cent of our total production mix. However, India’s per capita cement consumption at around 235 kg is less than half of the global average (520 kg).

Surging Demand
The economic growth we are foreseeing over the next few years and decades including the target of becoming a $5 trillion GDP will push the demand for cement to much higher levels. The surge in demand for cement can be environmentally sustained only by our efforts to push for wider use of blended and green cement. From the manufacturers point of view such a shift is already gaining a lot of momentum through more investment in R&D-led innovation to improve products and processes and in no small measure a strong and consistent consumer-focussed advocacy.
As one of the leading markets for cement in the world, this is an historic opportunity for India to establish its leadership in the true sense of the word.

India’s Cement Sector Cuts Energy Use, but Worker Safety Worsens

iFOREST finds efficiency gains alongside water and safety concerns

India’s cement sector has improved its energy and carbon efficiency, but rising groundwater use in water-stressed regions and deteriorating worker safety remain significant concerns, according to a report by the International Forum for Environment, Sustainability & Technology (iFOREST). The findings also highlighted weak policy implementation and gaps in sustainability reporting.

India, the world’s second-largest cement producer, uses about 2.54 gigajoules of energy per tonne (GJ/t), below the global average of 2.88 GJ/t. However, renewable sources accounted for only 5.1 per cent of the sector’s energy mix, indicating continued dependence on conventional sources.

The report assessed 18 cement companies against 107 Business Responsibility and Sustainability Reporting indicators for FY24 and FY25. The companies covered 87 per cent of India’s cement production. Carbon emissions intensity declined from 0.58 to 0.57 tonnes of carbon dioxide per tonne, but total emissions increased 4 per cent to 224.3 mn t, equivalent to about 6 to 7 per cent of India’s overall emissions.

Overall water withdrawal declined 9.5 per cent during the study period, while withdrawals in water-stressed areas, mainly in Rajasthan, increased by more than 20 per cent. Groundwater’s share of withdrawals in these areas rose from 27 per cent to 38 per cent, raising concerns about the sector’s impact on vulnerable water resources.

The sector employs about 228,000 people, including 63 per cent contractual workers, 3.1 per cent women and 0.07 per cent persons with disabilities. Women in key managerial roles earned 26.8 per cent less than men, while median pay for women workers fell 11.1 per cent in FY25 as men’s pay increased. Worker injuries rose 36.5 per cent to 359, and fatalities increased from 17 to 22, with workers accounting for more than 90 per cent of deaths.

iFOREST recommended cement-specific reporting guidance, standardised metrics, mandatory production disclosure and third-party verification. It also called for environmental, social and governance policies to be integrated into business strategies and implemented more effectively on the ground.

Ambuja Cements expects its sales volumes to grow faster than the cement industry during the second half of fiscal year 2027, as it seeks a recovery in institutional demand after a weak first half. The Gautam Adani-owned company is aiming to rebuild volumes while protecting profitability.

The company reported a 90 per cent year-on-year decline in consolidated net profit attributable to owners of the parent to Rs. 1.93 bn for the quarter ended 30 September, from Rs. 17.74 bn a year earlier. The previous year’s profit included a reversal of income-tax provisions worth Rs. 16.97 bn. Revenue from operations rose marginally to Rs. 91.66 bn from Rs. 91.3 bn.

Trade volumes increased 8.6 per cent year-on-year in the September quarter, but weaker institutional sales left overall volumes broadly unchanged. Ambuja Cements expects both trade and institutional sales to turn positive in the third and fourth quarters. Trade sales are made through dealers and distributors, while institutional or business-to-business sales involve bulk supplies to infrastructure developers, government projects and real estate companies.

The company had earlier reduced institutional sales that did not generate adequate returns. It now plans to rebuild the business selectively, while continuing to prioritise trade sales and higher-value products. Trade accounted for 74 per cent of sales in the quarter, up six percentage points from a year earlier, while premium products increased to 37 per cent of trade sales from 35 per cent. Blended cement’s share rose to 82 per cent from 77 per cent.

Ambuja Cements commissioned 4.6 mn t of capacity during the quarter. Another 3.2 mn t at Bathinda in Punjab and Jodhpur has stabilised, with the facilities expected to ramp up in the second half. A further 2.4 mn t facility at Varkala in Bihar is scheduled for commissioning during the period. Higher fuel and logistics costs remain a challenge, while the company has realised a cement price increase of about Rs. 10 per bag in October and is targeting operating costs of Rs. 4,250 per t for the full year.
