Sustainable Building: Ensuring Value for Money in the Cement and Concrete Industry


Value for Money: The global cement and concrete industry is a cornerstone of modern construction, providing essential materials for infrastructure development.

However, it also stands as a significant contributor to CO2 emissions. As the world shifts towards sustainable practices, the industry faces the dual challenge of reducing its environmental impact while ensuring value for money for stakeholders.

This article delves into the intricacies of emissions, market opportunities, technological advancements, cost considerations, investment trends, and regulatory frameworks, providing a comprehensive guide on how to ensure the best value for money in sustainable building materials.

Understanding CO2 Emissions in the Cement and Concrete Industry

Cement production is inherently carbon-intensive, primarily due to the transformation of limestone (CaCO3) into lime (CaO), a key ingredient in clinker. This process releases significant amounts of CO2.

Additionally, clinker production is energy-intensive, consuming about 945 kWh per tonne, with 90% of this energy being fossil-based. Cement production further adds approximately 100 kWh per tonne. Addressing these emissions is crucial for the industry’s sustainability efforts.

Market Opportunities and Growth Projections

The global concrete market was valued at $617 billion in 2020 and is projected to reach $972 billion by 2030, with a compound annual growth rate (CAGR) of 4.7%. The market is divided into ready-mix concrete and precast concrete.

Ready-mix concrete is delivered in a fluid state to construction sites, while precast concrete is cast and cured offsite before installation.

Green and recycled concrete are emerging as environmentally friendly alternatives, offering a lower carbon footprint and incorporating recycled materials.

Technological Advancements in Concrete Production

Technological innovations are driving the green concrete market, which is experiencing rapid growth with a CAGR of around 12.8% from 2023 to 2029. Advances in concrete composition and production processes are pivotal in reducing the environmental impact of construction materials.

Europe currently leads the global green concrete market, with its size valued at approximately $9.3 billion in 2023 and projected to reach $21.8 billion by 2032, growing at a CAGR of 9.6%.

Price Parity and Cost Considerations in Green Concrete

Achieving value for money with green concrete often involves lower costs compared to traditional grey concrete. This is due to the use of industrial waste materials such as fly ash, slag, and silica fume, which are cheaper than virgin raw materials.

Carbon capture and storage (CCS) technologies, used in blue cement/concrete, also offer potential cost benefits by reducing raw material needs, though their current scalability and costs remain challenging.

Emerging technologies like biotechnology, electrochemistry, and alternative building materials are still in their nascent stages (TRL 1–6) and may take over five years to mature and become commercially viable.

These innovations hold promise for further reducing the environmental footprint of cement and concrete production.

Transitioning to net-zero emissions in the cement industry is expected to increase costs by 40–120%, translating to a modest 1.5–3% rise in overall construction costs. This suggests a willingness among stakeholders to absorb higher costs for sustainable materials.

The estimated total investment needed to achieve net-zero emissions by 2050 is $1.42 trillion, covering cement-making equipment, supply chain infrastructure, and carbon capture technology.

Public and private sector commitments are driving investment in sustainable construction materials. Initiatives like ConcreteZero, led by the Climate Group, aim for 100% net-zero concrete by 2050.

Companies like Brimstone and Sublime Systems have secured significant funding, indicating strong market interest in low-carbon cement.

Regulatory Landscape for Green Concrete

The regulatory landscape for concrete is conservative due to the critical safety requirements of structural applications. In Europe, the EN framework classifies concrete by strength, durability, and composition.

Recent updates, such as EN 197–6, have increased the allowable percentage of recycled materials in cement to 35%. The Carbon Border Adjustment Mechanism (CBAM) aims to equalize CO2 reduction costs between EU and non-EU cement suppliers, becoming effective in 2027.

In the United States, the Inflation Reduction Act (IRA) has allocated $6 billion for decarbonizing energy-intensive industries, including cement, with the goal of achieving net-zero emissions by 2050. Specific regulations, such as the approval of CarbonCure as an ASTM C494 Type S admixture, support these efforts.

Globally, the Global Cement and Concrete Association (GCCA) has outlined a roadmap to net-zero production by 2050, focusing on carbon capture, process optimization, and concrete reuse. Major cement companies worldwide are participating in this initiative.
