But concrete still remains the most used building material worldwide. “We can’t get away from concrete, but we need to use it better.” The workshop focused on how to improve material efficiency. “We have to use all materials,” Scrivener noted, “but we need to consider where they come from and how they can be produced as energy-efficiently and emissions-free as possible.” Co-moderator Harry Gugger presented the workshop findings in the form of six propositions. The first was “Reduce materials need and impact by intelligent Marginal gains for a big effect “The reality that we are facing is the explosion in demand of construction materials.” This is not only negative; it has led to an improved standard of living for millions of people. But it cannot be denied that one cause of accelerating climate change is that the enormous demand for new buildings is being met with the consumption of available materials.
