World Environment Day on 5th June was ushered in with a greater gusto in India than ever before. In keeping with the theme of this year’s celebration, ‘Only One Earth,’ the Government of India has also taken substantial steps such as banning single use plastic among others.

Considering the urgency with which the cement sector is moving towards decarbonisation, here are some facts that are propelling cement players to take immediate action:

The steel and cement sectors would see a three-to-four-fold increase in demand and a near tripling of sectoral CO2 emissions by 2050, making the industrial sector the single largest source of CO2 emissions in India, as per an estimate by The Energy and Resources Institute (TERI) and World Business Council for Sustainable Development (WBCSD).
More than half of all CO2 emissions since 1751 have been emitted in the last 30 years, says a study by Institute for European Environmental Policy (IEEP).
The 20 big companies that contributed to almost 33 per cent of world-historic emissions are from the energy and cement sectors.
The per capita consumption of cement in India is 195 kg, which is far less than the world average of 500 kg and 1000 kg of China, as per Bureau of Energy Efficiency.

Decarbonisation of the cement industry cannot be achieved without technology. Using state-of-the-art technology, cement companies should aim at…

Making their processes more energy efficient
Using renewable energy sources
Shifting to alternative fuels
Investing in carbon capture and storage
Utilising other industrial waste as raw material
Exploring alternative cementitious materials
Recycling waste and having circular processes

Technology and R&D are the two tools that will enable the cement sector to harness alternative energy such as solar thermal power, make improvements in the usage of biomass and green hydrogen and increase material circularity.
A significant achievement in India has been the substitution of part of the limestone with by-products from other processes in the form of industrial wastes like slag from steel plants and fly ash from thermal power plants. This blending has greatly contributed to helping the Indian cement industry perform better than global players in terms of specific emissions of CO2 per tonne of cement. Slag Cement can substitute 70-80 per cent of OPC in various grades of concrete mixtures, while it can be used 100% in massive mass concrete projects and other industrial structures. Achieving higher thermal efficiencies helps conserve the use of coal. Equally noteworthy has been the gainful utilisation of industrial, municipal and agricultural wastes and biomass to serve as alternative fuels that replace fossil fuels.
We see a lot of constructive initiatives undertaken by the government, too, in this journey towards decarbonisation. For instance, last year, India and the United Kingdom announced the Industrial Deep Decarbonization Initiative (IDDI). It is one of the largest and most diverse coalitions of governments and the private sector to create net-zero carbon industrial products. Over the next three years, the governments will work towards decarbonisation of heavy industries, including, of course, cement. While the sentiment is in the right place here, only time will tell if the efforts match up to the expected outcome.

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.
