Cement has the highest carbon footprint construction materials.Estimated that every person take up 3 tonnes of cement in the world, Imagine how much CO2e of our world population of 7 billion? It's manufacturing alone make up of 4% of world CO2e.
It has become a norm in any building construction since it's introduction, ranging from reinforcement concrete to wall plastering, floor screeding and mortar for bricklaying. Since its present is essential to current construction technology it is necessary to find ways to minimize its wastage by close monitoring and control during the construction stage.
Good news is that more and more materials& construction technology is emerging in replacing the high cement content materials. however, most of the builders and developers in Malaysia still a distance far from adopting a relative high initial cost green materials but what worst is that even materials wastage control is almost none-existence.
Hope the spreadsheet below help builders in calculating the quantity needed, allowing more accurate estimation in monitoring and control its usage, and eventually reduce the wastage and cost.
*The Carbon equivalent calculated in the spreadsheet is embodied carbon during manufacturing stage only. A cradle-to-grave or cradle-to-cradle stage will need more information from sourcing, transportation to operation during its expected life duration to deconstruction and reuse or recycle.
