Concrete is tipping us into climate catastrophe

from The Guardian: …Cement, the key component of concrete and one of the most widely used manmade materials, is now the cornerstone of global construction. It has shaped the modern environment, but its production has a massive footprint that neither the industry nor governments have been willing to address.

Because of the heat needed to decompose rock and the natural chemical processes involved in making cement, every tonne made releases one tonne of C02, the main greenhouse warming gas…

…up to 8% of the world’s, are now sourced from cement production. If it were a country, the cement industry would be the third largest in the world, its emissions behind only China and the US…

…technological change will not alone drive cement emissions down fast enough. What is needed to speed up cuts is a global cement, or concrete tax. Only if the whole industry is forced to pay far more for the emissions of its product will companies shift to cleaner practices…

…The cement industry has transformed the world and enriched both itself and mankind. But it now threatens to tip the environment into uncontrolled warming. It’s now payback time and the industry must respond urgently to the problem it has helped to create.

I don’t believe the pressing need for decarbonization has broadly reached the construction industry in many parts of the world,” Vass said.
