Cement plants account for 5 percent of global emissions of carbon dioxide, the main cause of global warming. Cement has no viable recycling potential; each new road, each new building needs new cement. Making cement means making pollution, in the form of carbon dioxide emissions.

Concrete is the most common construction material used in the world. Cement is the principal ingredient in concrete. Producing one tonne of cement results in the emission of approximately one tonne of CO2,besides CO2, both cement and concrete production generate considerable quantities of air-pollutant emissions.

Red-hot kilns used to make cement (a primary ingredient of concrete) emit 5 percent of the world’s man made carbon dioxide. Which is main pollutant for global warming and climate change. Cement can absorb this green house gas from the air and it can help a lot to reduce CO2 level into the air. Cement has a huge environment burden.
