Feature: Change.jpeg - Cement Production
Updated: Aug 19, 2022
Cement production accounts for about 8% of global carbon dioxide emissions. Why? This is because the process used to produce calcium for cement requires the burning of limestone, which produces carbon dioxide. Making 1 ton of cement creates 1 ton of carbon dioxide. To build the average US sized home (2400 sq ft), roughly 45600kg of cement are used, producing 45600kg of carbon dioxide in the process. This would take 1000 trees a little more than 2 years to absorb.😱
There’s probably not much you can do to tackle this problem, unless you happen to own an architectural firm. However, promising research is being done, with researchers trying to create biocement, green concrete, and others even trying to make it out of seawater!
