A graphic from The Oil Drum — Gigatons per Year of Cement Produced:
Quoting from the website:
Remember, in China, oil isn't used in cement production. In the "clinker" stage, it's all coal. In the blending stage it's electricity (which is generated 80% from coal in China).And cement production in China is inefficient. There are hundreds of small plants, both wet and dry processes, and the local environmental impact is severe.
There is some interesting discussion about the chart in that site's comments.
For more about cement production and its environmental impacts, see the Environmental Building News feature, "Cement and Concrete: Environmental Considerations." Much more information about the cement industry is in BuildingGreen Suite as well.
