Commission Publishes Life-Cycle GWP Calculation Framework for Construction Materials

The European Commission published a calculation framework for determining life-cycle global warming potential (GWP) of construction materials. This framework supports implementation of the revised Energy Performance of Buildings Directive (EPBD), which requires life-cycle GWP to be calculated and disclosed in energy performance certificates for new buildings over 1,000 m² from January 2028, extending to all new buildings from January 2030. The methodology harmonizes life-cycle assessment approaches across the EU, building on ISO 14040/14044 principles to ensure consistent measurement of embodied carbon in construction products.
