This session explores why the construction industry needs to shift from using Supplementary Cementitious Materials (SCM) percentages to Global Warming Potential (GWP) data as the primary metric for measuring concrete sustainability. Industry leaders will discuss how this transition can drive more meaningful carbon reductions and better align with broader sustainability goals.

Key discussion points:

• Why SCM percentages alone are an insufficient proxy for concrete decarbonisation
• How GWP data provides a more accurate measure of environmental impact in kg CO2 per cubic metre
• The availability of GWP data through Environmental Product Disclosures (EPDs)
• Real-world examples of successful implementation of GWP-based requirements
• Strategies for incorporating GWP criteria into procurement and construction processes
