US: The Portland Cement Association (PCA) hosted a one-day session in mid-June 2023 aimed at establishing guidelines for the definition of 'low carbon' cement and concrete. The association called the session a 'Critical first step' towards ensuring clarity for stakeholders.
The PCA said "Low carbon is increasingly defined in the eye of the beholder, with little or no regard to either upstream and downstream impacts or short-term and long-term strength, durability and resilience concerns."
