Concrete cancer - what's the cure for 9% of global emissions?
Concrete is everywhere yet its use comes at an alarming environmental price, but new production techniques and alternative materials could help cure the cancer that concrete represents for the planet's health.
Concrete is used so copiously that its emissions are greater than all countries except for China and the United States. (Image source: Shutterstock.com)
More concrete is made by humans than any other product on Earth and with that voluminous output comes almost a tenth of all human carbon dioxide emissions.
Every kilogram of cement that is made sends a kilogram of CO2 into the atmosphere.
While cement and concrete have essentially been made the same way for a century, new techniques utilising alternative materials and processes do offer hope for a greener concrete future.
