Survey Questions

  • where is this project located (city, state/province, country)
  • does the country/region the project is located in have existing laws/regulations regarding legal wood? are they effectively enforced?
  • how much wood, relative to other materials, was used on this project (by cost)?
  • prior to attempting this credit, what was your understanding of illegal wood in the buildings industry supply chain in your region?
  • prior to the work the project team did on this credit, was verified legal wood something that was required in any standard project spec used by the project team?
    • if yes, what specific language was used?
    • if no, did the project team develop standard specification language for future use?
  • What specific piece of this ACP was the most difficult:
    • 100% legality verification?
    • 70% responsibly sourced verification?
    • procurement of certified wood?
  • was legality documentation readily available from your upstream wood suppliers?
    • what documentation were they able to provide?
    • was this the first time that a project team asked the supplier for documentation to verify legality for wood?
  • who, on the project team, was responsible for documentation? did the project team need to hire an outside expert to facilitate achievement?
  • Did this credit influence or change the wood that was ultimately used on the project?
  • One of the goals of this ACP is to assess the feasibility of the creation of a prerequisite around legal sourcing of building materials.
    • How transformational do you think a prerequisite requiring legality verification for forest products would be?
    • How feasible do you think a prerequisite requiring legality verification of forest products would be?
    • How feasible do you think legality verification of all materials would be?
