Unknown to most and alarmingly, cement, the soul of concrete is responsible for roughly 7% of all global emissions, which is more than aviation and deforestation combined.
To reduce carbon footprint, there's a growing focus on cement tech these days, as it happens to be one of the trickiest obstacles on the path to getting carbon emissions down to net zero by the year 2050.
Finally On The Path to Net Zero
Forty of the world’s leading cement and concrete manufacturers joined forces yesterday to accelerate the transition to greener concrete by pledging to cut CO2 emissions by a further 25% by 2030, taking a giant step towards ‘Net Zero’ concrete by 2050.What's In The Mix?
Also on the cards are usage of alternative fuels, new chemistry and manufacturing processes, carbon capture and storage, increased efficiency in concrete use and pushing governments to approve new forms of concrete and buy them.
While the GCCA members have together outlined an ambitious programme, they have also called on governments, designers and contractors to fully play their part by assembling the right public policies and investments to support this global scale green transition.
While various pilot projects will be rolled out from 2023 onwards to ensure the goal is reached on time, it is time to see how governments and the private sector react to increased short term costs that such a green switch demands.
