Armstrong vinyl plank flooring

I looked on the site to see if I could find any reviews for floor paneling or tiling manufacturers offering a reasonable level of effort to create sustainable products for the cost and environmentally concerned customer =) I was/am happy to say that I believe I found that manufacturer in Armstrong's Vinyl Plank Flooring. Offering flooring options which are composed of recycled and smart sourced wood was reassuring as was seeing that the manufacturer hold's themselves to the same expectations with a LEED platinum rated headquarters for the North American Production. Feel free to view their page here. http://www.armstrong.com/flooring/armstrong-flooring-sustainability.html My question however, is how closely is the production measured/tested? Is there a universal certification offered?
