The project consists of ceramic tile flooring and precast concrete ceiling panels in some areas. According to LEED standards, these products are inherently non-emitting sources. How can we demonstrate that these products do not emit pollutants by their nature?

the most current version of the v4.1 reference guide provides some detailed guidance, that was not included in earlier versions.
"Stone, ceramic, and porcelain tiles; powder-coated metals, plated or anodized metals, glass, clay brick, and solid wood are material which, on their own, are considered inherently nonemitting without additional information. For any other materials, a manufacturer chemical inventory of the the product to at least 0.1% (1,000 ppm) is required to confirm the product complies with the inherently nonemitting sources criteria."
also in the most current v4.1 ref guide:
"exclude poured concrete...wet-applied products applied to the floor should be included within the paints/coatings category".
In your instance, I believe ceramic tiles get a pass but the precast concrete ceiling panels will probably require an Health Product Declaration to confirm compliance. Since concrete often includes more than stone, gravel, sand, cement and water...there are probably plasticizers and hardeners added to the concrete - and these items may include emitting sources.
Hope this Helps!

Can we use a concrete trail mix report to ensure compliance with credit complaints?
Thank you
