Global cement demand is expected to grow by 3.2% in 2024, yet cement and concrete are still responsible for roughly 23% of global CO2 emissions from cement and concrete related processes in 2022, a mismatch that makes efficiency and clinker replacement more urgent than ever. From energy intensity of about 3.2 to 3.5 GJ per tonne of clinker to policy pressure under EU ETS rules, the industry is shaped by a few measurable levers that can swing emissions outcomes. We track the key KPIs, fuel and SCM shares, and durability linked performance factors that together explain why different plant and mix choices can lead to very different footprints.
Key Takeaways
- In 2022, global clinker production capacity expansion was driven by Asia-Pacific (IEA/World Cement)
- Blast furnace slag is one of the major SCMs used in blended cements (WBCSD)
- Fly ash is a major SCM; availability depends on coal power generation (IEA)
- ~23% of global CO2 emissions are estimated to come from cement and concrete-related processes in 2022 (IPCC AR6 synthesis estimate range)
- Typical specific energy consumption for cement clinker production is ~3.2–3.5 GJ/tonne clinker (IEA/industry benchmarks)
- “Clinker factor” is a key KPI; reducing clinker factor by 10 percentage points can cut process-related CO2 proportionally (IPCC methodology)
- Global ready-mixed concrete production is typically reported as hundreds of billions of USD market value; US$ cash value estimates vary by source (market sizing varies by definition)
- USGS reports US cement consumption in thousand metric tons annually (USGS cement statistics page)
- 5.0 billion tonnes global cement demand in 2023, indicating scale of annual consumption worldwide
- Portland cement hydration produces calcium silicate hydrate (C-S-H) as main binding phase (peer-reviewed review)
- Portland-limestone cement increases cement performance in some environments; typical limestone replacement can be up to 20–35% depending on standard (EN 197-1)
- Concrete carbonation depth increases roughly with square root of time for many exposure conditions (peer-reviewed modeling)
- 9.0% of all cement produced in the United States used coal as a fuel in 2022, indicating fuel mix contribution to operating emissions
- 25.0% of the world’s electricity is produced in coal-fired plants in recent years, which constrains fly ash availability for cement blending in coal-ash supply chains
- 0.5–3.0% of cement kiln feed moisture content can be reduced through waste-heat dryer systems, improving kiln energy efficiency in industrial configurations
Cement and concrete are projected to drive large emissions, but better clinker and energy efficiency could cut CO2 significantly.
