The CIB Working Commission W115 "Construction Materials Stewardship" was established in January 2007. The W115 taskforce mission is to:

  • drastically reduce the deployment and consumption of new non-renewable construction materials, to replace non-renewable materials with renewable ones whenever possible, to achieve equilibrium in the demand and supply of renewable materials and ultimately to restore the renewable resource base, and

  • carry out these tasks in ways to maximize positive financial, social and environmental and ecological sustainability effects, impacts and outcomes.
