Abstract: The Building & Infrastructure sector in India is a prime contributor to the CO2 emission in the atmosphere. This is because of the developing economic system and because of the boom in construction activity, growing use of energy-intensive materials like cement, brick, steel. The inevitable boom of the population in the the coming decade will bring about big boom in the the use of constructing materials. The simplest feasible way to minimise the CO2 emission is to evolve to "Sustainable Materials" or "Alternative Building Materials" which might be low energy materials. The Indian construction sector is amongst the largest in ingesting the raw materials/natural assets and the production of construction materials. A giant type of products and materials are being manufactured and eaten up in the construction sector like Cement, Steel, Bricks and many others. Buildings have varieties of carbon emission: Embodied carbon and Operational carbon- Where embodied carbon emission refers to the whole quantity of greenhouse emission precipitated in the course of the existence cycle of the building material while operational carbon emission refers to the whole sum of whole greenhouse emission of the whole construction other than the materials, electricity consumption, heating, cooling and many others. Natural materials along with soil, stones, wood and many others are the precise building materials to reap low carbon footprint, and they possess a great ability of reuse and recycling/ or they may be bio-degradable placing no damage to the environment. Some materials and techniques are- Blended cement, Stabilized mud blocks, Compacted fly ash blocks, Rammed earth wall, Less energy-intensive flooring & roofing system.
