World Cement Association Calls for Industry Action

The cement industry is responsible for 8 per cent of global CO2 emissions

The cement industry is responsible for 8 per cent of global CO2 emissions—a staggering figure that demands urgent action, particularly as 2024 marked the first year the planet surpassed the 1.5°C global warming limit. Recognising this critical juncture, the World Cement Association (WCA) has released a landmark White Paper, “Long-Term Forecast for Cement and Clinker Demand”, which projects a sharp decline in long-term cement and clinker demand. By 2050, annual clinker production is expected to fall below 1 Gt from its current level of 2.4 Gt, with far-reaching implications for global carbon emissions and the viability of carbon capture projects.

WCA CEO Ian Riley underscores the complexity of this challenge:
“Carbon capture remains a vital tool for tackling emissions in hard-to-abate sectors like cement. However, flawed demand assumptions and the fragmented nature of cement production globally could undermine the feasibility of such projects. Industry stakeholders must rethink their strategies and embrace innovative, sustainable practices to achieve meaningful emissions reductions.”

Key Findings from the WCA White Paper
The WCA White Paper provides a comprehensive roadmap for the industry’s decarbonisation journey, highlighting the following critical insights:
1. Declining Cement and Clinker Demand: Global cement demand is expected to drop to approximately 3 billion tonnes annually by 2050, while clinker demand could decline even more steeply, reaching just 1.5 billion tonnes annually.
2. Implications for Carbon Capture and Storage (CCS): With reduced clinker production, the need for CCS is expected to decline, necessitating a shift in investment and policy priorities.
3. Alternative Materials and Clinker-Free Technologies: These innovations hold transformative potential for reshaping demand patterns and cutting emissions.
4. Supply Chain Optimisation: Enhancing logistics and reducing waste are key strategies for adapting to evolving market dynamics.

A Path to Lower Emissions
Clinker production, the largest source of CO2 emissions in cement manufacturing, generates one-third of emissions from fuel combustion and two-thirds from limestone decomposition. According to our white paper, transitioning to lower-carbon fuels could reduce specific fuel emissions per tonne of clinker by nearly 70% by 2050. Overall CO2 emissions from cement production are forecast to decline from 2.4 Gt in 2024 to less than 1 Gt by 2050, even before factoring in carbon capture technologies.

Ian Riley emphasised: “This white paper provides actionable insights to help the cement industry accelerate its decarbonisation journey. By prioritising innovation and collaboration, the industry can achieve substantial emissions reductions and align with global climate goals.”

The need of present time is stronger buildings, industrial or common utility buildings, such as Malls, Railway stations, hospitals, offices, bridges etc. For this, there is need of long durable, tough and stable concrete, which could stand under normal and seismic conditions. Tough railway bridges are required for bullet trains to pass without any damage. Railway tunnels, sea-links, coastal roads, bridges and multistorey buildings, are the need of the hour. The question comes, is the normal cement called OPC is sufficient to take care of such requirements or better combination of cements and sand mixtures is required?
Introduction
A good stable building structure can be made with a good quality of cement+sand+water system. Its quality can be enhanced by keeping the density of admixture higher (varies from 30 in normal buildings to bridges etc to 80). Further enhancement in the properties of various cements admixtures is made by adding several additives which give additional strength, waterproofing, flexibility etc. These are called construction chemicals…

The National Council for Cement and Building Materials (NCB) has signed a memorandum of understanding with a leading cement manufacturer to strengthen skill development and capacity building in the construction sector. The agreement was formalised at NCB premises in Ballabgarh and was signed by the Director General of NCB, Dr L. P. Singh, and the head of technical services at UltraTech Cement Limited, Er Rahul Goel. The collaboration seeks to bring institutional resources and industry expertise into a structured national training effort.

The partnership will deliver structured training and certification programmes across the country aimed at enhancing the capabilities of civil engineers, ready?mix concrete (RMC) professionals, contractors, construction workers and masons. Programme curricula will cover material quality testing, concrete mix proportioning, durability assessment and sustainable construction practices to support improved construction outcomes. Emphasis is to be placed on standardised assessment and certification to raise practice levels across diverse construction roles.

Practical learning elements will include workshops, site demonstrations, technical seminars and exposure visits to plants and RMC facilities to strengthen applied skills and on?site decision making. The Director General indicated confidence that a large number of professionals and workers would be trained over the next three to five years under the initiative. The partnership is designed to complement flagship government schemes such as the Skill India Mission and to align training outputs with national infrastructure priorities.

By combining the council’s technical mandate with industry experience, the initiative aims to develop a more skilled and quality?conscious workforce capable of meeting rising demand in infrastructure and housing. NCB will continue to coordinate programme delivery and quality assurance while industry partners provide practical exposure and technical inputs. The collaboration is expected to support long?term capacity building and more sustainable construction practices nationwide.

JSW Cement has strengthened its national presence by commencing production at its greenfield integrated cement plant in Nagaur, Rajasthan, marking its entry into the north Indian market.
With this commissioning, the company’s installed grinding capacity has increased to 24.1 MTPA, while total clinker capacity, including its joint venture operations, stands at 9.74 MTPA.
The Nagaur facility comprises a 3.30 MTPA clinkerisation unit and a 2.50 MTPA cement grinding unit, with an additional 1.00 MTPA grinding capacity currently under development. Strategically located, the plant is positioned to serve high-growth markets across Rajasthan, Haryana, Punjab and the NCR.
The project has been funded through a mix of equity and long-term debt, with Rs 800 crore allocated from IPO proceeds towards part-financing the unit.
Parth Jindal, Managing Director, JSW Cement, stated that the commissioning marks a key milestone in the company’s ambition to become a pan-India player. He added that the project was completed within 21 months and positions the company to achieve its targeted capacity of 41.85 MTPA by FY29.
Nilesh Narwekar, CEO, JSW Cement, highlighted that the expansion aligns with the company’s strategy to tap into rapidly growing northern markets driven by infrastructure development. He noted that the company remains focused on delivering high-quality, eco-friendly cement solutions while progressing towards its long-term capacity goal of 60 MTPA.
The Nagaur plant has been designed with sustainability features, including co-processing of alternative fuels and a 7 km overland belt conveyor for limestone transport to reduce road emissions. The facility will also incorporate a 16 MW Waste Heat Recovery System to improve energy efficiency and lower its carbon footprint.
JSW Cement, part of the JSW Group, operates across the building materials value chain and currently has eight plants across India, along with a clinker unit in the UAE through its joint venture.
