I'm working on a project in Norway and I'm somewhat confused about the documentation for Certified Wood.

The Reference Guide states: Collect all *vendor* invoices for permanently installed wood products, FSC certified or not, purchased by the project contractor and subcontractors. Vendors are defined as those companies that sell products to the project contractor or subcontractors”.

So I read this as saying I *only* need invoices from vendors – correct? Not earlier in the supply chain? The diagram in the Reference Guide (Figure 1, page 270) seems to imply that organizations earlier in the supply chain need to provide documentation too (forest needs certificate, transportation company may need CoC ). Or is this covered by the invoice? The form on LEED Online only asks for 100% of “invoices”. I’ve asked around, and people I know have gotten project certified both ways.

Also, I have a casework sub providing casework, and their organization has FSC certification, and I have a document stating that. According to this FAQ helpfully posted previously https://us.fsc.org/frequently-asked-questions.296.htm “All other organizations will need to be FSC CoC certified in order for the certified wood products they fabricate and install to count toward MRc7. This includes organizations like cabinetmakers and architectural millworkers that manufacture products off-site and then install them on-site (even if considered a subcontractor).” So they comply with this.

But, I’m unclear who is the vendor in this case – the casework shop, or the people who sold the wood to them? If the casework shop is the vendor (selling to the contractor), then they need to provide an invoice for that sale (to the contractor)?

The second question is more to gain any insight (I think I know the answer). Why does this credit require not only itemizing the *non* FSC new wood, but also requires you to provide invoices for this non-FSC wood? Other credits, for example MRc4 - Recycled, allow you to just report only the qualifying recycled material, and not even itemize the non-recycled material. Why is this credit different? Why can’t you just report the total cost of all new wood and just provide the documentation for the certified wood? I am having a difficult time getting this documentation, and I don't understand the point of it.

Thanks
