World Cement Association Calls for Industry Action

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

Published

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 Cyberabad Traffic Police issued a traffic advisory as road works begin for the laying of a cement concrete (CC) road from Jaya Shankar Statue to RRR Restaurant at Parvathnagar in Madhapur limits. The advisory indicated that traffic diversions will be in place for 30 days from May 16 to ensure the smooth flow of vehicles and to minimise congestion on the affected stretch. The measure aims to balance uninterrupted construction activity with the movement needs of commuters.

Traffic moving from Toddy Compound towards Parvathnagar village will be diverted at Parvathnagar junction towards Sunnam Cheruvu and the 100 feet road. Local motorists and public transport operators have been advised to follow the diversionary route as directed by traffic personnel on duty. Alternate routes and signage have been planned to mitigate delays and to manage peak hour congestion.

Police officials said the diversion had been planned to facilitate uninterrupted road works while maintaining traffic movement in the area. Commuters were urged to plan their travel accordingly and to cooperate with traffic staff managing the stretch. Authorities indicated that enforcement of diversions would be active and that violations could attract penalties.

The 30 day schedule is intended to allow contractors to complete the laying and curing phases with minimal interruption to vehicular flow. Residents and businesses in adjacent localities have been advised to factor the diversion into deliveries and travel plans. The traffic police promised continuous monitoring of the works and the operational diversions and emphasised that temporary inconvenience was necessary for longer term improvement of the road network. Traffic personnel will be stationed at key junctions and additional signage and temporary markings will be displayed to guide motorists and pedestrians through the revised alignments while public transport services will follow the diversion where feasible and operators have been asked to adjust timetables to minimise disruption.

HeidelbergCement India (HeidelbergCement India) has received regulatory consent to establish a cement blending and grinding unit at Village Dongaliya, Tehsil Punasa, District Khandwa in Madhya Pradesh. The consent was granted by the Madhya Pradesh Pollution Control Board under the Water (Prevention & Control of Pollution) Act, 1974 and the Air (Prevention & Control of Pollution) Act, 1981 and is dated 17 May 2026. The company disclosed the development in a filing made under Regulation 30 of the SEBI (Listing Obligations and Disclosure Requirements) Regulations, 2015.

The project plan envisages procurement of long term availability of fly ash and the allotment of land on lease for setting up the unit. The proposed facility is described as a blending and grinding installation which will process cementitious materials sourced from nearby operations and suppliers. Company filings state the measures required to secure raw material logistics and statutory compliance before commencing construction.

The addition of a grinding unit in Khandwa is intended to strengthen regional supply and improve logistical efficiency by reducing haulage distances for finished product. The unit is expected to complement existing capacities in central India and to offer flexibility in product mix through blending operations. The reliance on fly ash as a supplementary cementitious material will necessitate long term supply agreements with thermal power producers and coordination with waste utilisation policies.

The disclosure to the regulator and to the stock exchanges follows standard corporate governance practice and aims to keep investors apprised of capital expenditure initiatives. The company indicated that subsequent permits and clearances would be sought in accordance with applicable environmental and land use rules. The project is presented as part of HeidelbergCement India’s broader strategy to optimise capacity distribution and to respond to regional demand dynamics.

The new solution promisescontinuous, real-time tertiary air flow measurement in cement plant operations.

PROMECON GmbH has launched the McON IR Compact, an infrared-based measuring system designed to deliver continuous, real-time tertiary air flow measurement in cement plant operations. The system addresses the longstanding process control challenge of accurate tertiary air monitoring under extreme kiln conditions. It uses patented infrared time-of-flight measurement technology that operates without calibration or maintenance intervention.

Precise tertiary air measurement is a critical requirement for stable rotary kiln operation. The McON IR Compact is engineered to function reliably at temperatures up to 1,200°C and in the presence of abrasive clinker dust. Its vector-based digital measurement architecture ensures that readings remain unaffected by swirl, dust deposits or drift. Due to these conditions conventional measurement systems in pyroprocess environments are often compromised.

The system is fully non-intrusive and requires no K-factors, recalibration or periodic readjustment, enabling years of uninterrupted operation. This design directly supports plant availability and reduces the maintenance overhead typically associated with process instrumentation in high-temperature zones.

PROMECON has deployed the McON IR Compact at multiple cement facilities, including Warta Cement in Poland. Plant operators report that the system has aided in identifying blockages, optimising purging cycles for gas burners, and supplying accurate flow data for AI-based process optimisation programmes. The practical outcomes include more stable kiln operation, improved process control, and earlier detection of process disturbances.

On the energy side, real-time tertiary air data enables reduction in induced draft fan load and helps flatten process oscillations across the pyroprocess. This translates to lower fuel and energy consumption, fewer unplanned shutdowns, and a measurable reduction in NOx peaks. This directly reflects on the downstream cost implications for plants operating SCR or SNCR systems for emissions compliance.
