How 'green' concrete can help cities fight climate change

Aug 15, 2021Low-carbon concrete involves injecting recycled CO2 from industrial emitters like fertilizer and power plants into concrete. The CO 2 then chemically converts into a mineral and gets embedded in the concrete, making it stronger and helping concrete producers use less cement for roads and buildings.. The built environment is responsible for over 40% of the world's CO2 emissions

Carbon dioxide capture from emissions sources will increase by several orders of magnitude between now and 2021 as the world decarbonises fossil fuel usage. Much of that captured carbon dioxide (CO2) will be sent underground for permanent storage in geological formations and much of it will be utilised for emerging CO2 applications.
