The rating for cement relies on kilograms of embodied carbon dioxide equal per tonne (KgCO2e/t). For concrete, it’s kilograms per cubic metre (KgCO2e/m3).
The rating is expressed as “World Warming Potential” (GWP), calculated in response to Environmental Product Declarations (EPDs) requirements.
Definitions for “low carbon” and “close to zero” carbon emissions got here from the cement manufacturing definitions of the Worldwide Power Company and the GCCA 2050 Cement and Concrete Trade Roadmap for Internet Zero Concrete.

“As world demand for sustainable development grows, the necessity for higher transparency across the carbon footprint of development supplies is extra vital than ever.”
He stated the brand new system would “empower your entire worth chain to speed up decarbonisation”.
Riccardo Savigliano, head of vitality and decarbonisation on the UN Industrial Growth Organisation, stated: “This can be a enormous step ahead in the direction of harmonising world definitions for low emission cement and concrete within the assist of decarbonisation.”
Marlène Dance, sustainable design skilled at Bouygues Bâtiment Worldwide, stated: “We imagine a globally constant carbon ranking system adopted by all nations and utilized by all concrete suppliers could be a recreation changer.”
