More companies are rolling out CO2-emissions friendly cement – but can the industry deliver a green building revolution in time to save the environment ?

If water is essential to life , cement must run a close second . It ’ s hard to think how our lives would function without the durable , waterproof and ubiquitous material . Around 2.5 tonnes of concrete are poured for every person on the planet every year and global demand isn ’ t likely to shrink soon either , when you consider many emerging economies are going through a construction boom and 80 percent of the world ’ s population is expected to live in cities by 2050 .
The one major drawback is that cement production accounts for around 8 percent of global CO2 emissions and more than half are linked to the process for producing clinker . The cement manufacturing process also includes emissions of airborne pollution in the form of dust , greenhouse gases , noise and vibration when operating machinery and during blasting in quarries , and damage to countryside from quarrying .
