Within the composite wood evaluation language, how would one account for or get recognition for a composite wood product that is exempt from CARB? .

What would be an example of such a product? Do you have emissions data, and/or info on whether UF was added?

Softwood plywood for example.

Barry, what is the binder used in softwood plywood?I think I have an answer to your original question, just checking a couple of things.

Barry, according to the expert at USGBC whom I spoke with, CARB exempt composite wood products automatically meet the composite wood requirements of this credit, with the reason given that they have no-added urea formaldehyde.

@Tristan Roberts Since there is no Carb exempt box/dropdown in the LEM material calculator. What would be the best way to go about documenting softwood plywood or OSB paneling since there is no formal certifiaction documents for these products only loose referances from manufactureres quoting sections of CARB TSCA which states softwood ply and OSB are not considered composite woods. Is it better to move these products to walls catogory and give up on the catogory because there is no CDPHv1.1 docs either?   Or keep these products in the composite wood catogory and in the URL for product info make a statements simialr to:  "Composite wood products are defined as particleboard, MDF and hardwood plywood. With respect to engineered wood products certified under the CARB/EPA TSCA VI regulations OSB and softwood plywood engineered wood products are not covered by the regulations."
