Building Better Today for a Better Tomorrow
Concrete is an ancient building material. It has been used in buildings, roads, sidewalks, bridges, tunnels, and more for centuries. As with almost any human invention, its production process has changed over the years. Today, thanks to new aggregate materials, concrete is mixed better. Modern concrete is more fluid, allowing it to be poured into different forms.
But the environmental impact of concrete making has worsened.
Today, each ton of concrete releases 0.91 tons of carbon dioxide,
according to National Ready Mixed Concrete Association data.
This amounts to more than 8% of global carbon pollution.
If concrete were a country, it would be the world’s third largest carbon emitter behind China and the US – you read that right!
We use 40 billion tons of concrete each year.
This is three times as much as forty years ago on a per capita basis. And the trend is only getting worse. Of great concern is the projection that the number of buildings worldwide is expected to double by 2060 – imagine the magnitude of the environmental impact by then.
Concrete is the most widely produced man-made material in the world. We must lose no time in reducing carbon emissions from its production.
GreenVibe has built a deep-tech solution to optimize concrete mixes and reduce overdesign in both planning and building. This saves 10 – 20% on cement use, creating substantial cost savings for builders as well as a significant improvement on sustainability.
It’s time concrete became greener.
We have to wake up to the fierce urgency of the now.
