We never talk about the emissions caused from cement, which produces more carbon dioxide than the entire aviation industry. Did you know that 5% of all CO2 production comes from cement?

There is finally an alternative. The British engineering firm, Novacem, has created a new cement that uses magnesium silicates, which emit no carbon dioxide when they are heated. As the cement hardens, it absorbs CO2. In all, it removes about .6 tons of carbon dioxide per ton of cement used.
