Action 2 Acting across the entire value chain The decarbonization of building materials and solutions will be a key issue for decades to come and requires cross-sectoral debate, from design to transport. Several approaches are possible, including redesigned formulations, modernized processes, lighter products, and optimized logistics. Next, we look at new practices to build better, while emitting less.

Operating in the context of extremely scarce raw materials, vast global fossil fuel consumption and climate change, the sector is determined to change its model of very high fossil fuel consumption. The linear approach to the use of buildings is shifting; those in the sector are now taking into account the entire life cycle of buildings, to reduce the carbon footprint. 52 SAINT-GOBAIN
