Cement is a conventional building material for construction industry. Emissions from cement manufacturing are one of the major contributors in global warming and climate change. It is estimated that 5-6% of all carbon dioxide greenhouse gases generated by human activities originates from cement production. This paper focuses to cover the environmental issues and problems with the cement as a building material in the construction industry at present and also studies the choice of fly ash, which is a waste material from coal industry and has a problem of disposal. As the flyash has the low embodied energy it can be used as an alternative energy efficient building material.

Keywords: Flyash, energy efficient, embodied energy, cement, environmental hazards.
