This ZEB Talk features presentations by Ms. Martina Alig and Ms. Wu Jiayan on embodied carbon emissions in the building sector. Ms. Alig introduces the Swiss Life Cycle Assessment Database (KBOB), a key tool for calculating and benchmarking embodied emissions. Ms. Wu highlights China’s rising embodied carbon share amid low-energy building growth and the challenges of creating a unified life cycle assessment database due to diverse climate zones and regional development differences.
