Each year, Saint-Gobain's Sustainable Construction Observatory produces a Worldwide Barometer to take the pulse of sustainable construction in the real world: perceptions, barriers and progress levers, anticipated solutions, the most active stakeholders, and so on. It allows us to measure progress and identify action areas in which to focus our collective efforts. The 2nd edition of this international survey was conducted by the CSA Institute. Discover the key findings of the Sustainable Construction Barometer (2nd edition).
